Toshiba Launches 100V N-Channel Power MOSFET with Its Latest Generation Process Technology[1] to Improve Efficiency in Switched-Mode Power Supplies for Industrial Equipment

KAWASAKI, Japan--(BUSINESS WIRE)--Sep 25, 2025--

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “ TPH2R70AR5,” a 100V N-channel power MOSFET fabricated with U-MOS11-H, Toshiba’s latest-generation process [1]. The MOSFET targets applications such as switched-mode power supplies for industrial equipment used in data centers and communications base stations. Shipments start today.

The 100V U-MOS11-H series improves on the drain-source On-resistance (R DS(ON) ), total gate charge (Q g ) and the trade-off between them (R DS(ON) × Q g ) delivered by Toshiba’s existing generation process, the U-MOSX-H series, reducing both conduction and switching power losses.

TPH2R70AR5 offers approximately 8% lower R DS(ON) and 37% lower Q g against TPH3R10AQM, a U-MOSX-H series product, plus a 42% improvement in R DS(ON) × Q g. It also achieves high-speed body diode performance through the application of lifetime control technology [2], which reduces reverse recovery charge (Q rr ) and suppresses spike voltage. Q rr is improved by approximately 38% and the R DS(ON) × Q rr is also improved by approximately 43%. These industry-leading [3] trade-off characteristics [4], both R DS(ON) × Q g and R DS(ON) × Q rr, minimize power loss, contributing to higher efficiency and power density in power supply systems. It also adopts the SOP Advance (N) package and offers excellent mounting compatibility with industry standards.

Toshiba also offers circuit design support tools: the G0 SPICE model, which verifies circuit function in a short time; and highly accurate G2 SPICE model that accurately reproduces transient characteristics. All are now available.

Toshiba will continue to expand its lineup of low-loss MOSFETs that enable more efficient power supplies and contribute to lower equipment power consumption.

Toshiba: TPH2R70AR5, a 100V N-channel power MOSFET with the latest generation process technology.

KAMPALA, Uganda (AP) — Uganda’s presidential election was plagued by widespread delays Thursday in addition to a days-long internet shutdown that has been criticized as an anti-democratic tactic in a country where the president has held office since 1986.

Some polling stations remained closed for up to four hours after the scheduled 7 a.m. start time due to “technical challenges," according to the nation's electoral commission, which asked polling officers to use paper registration records to ensure the difficulties did not “disenfranchise any voter.”

President Yoweri Museveni, 81, faces seven other candidates, including Robert Kyagulanyi, a musician-turned-politician best known as Bobi Wine, who is calling for political change.

The East African country of roughly 45 million people has 21.6 million registered voters. Polls were expected to close at 4 p.m., but voting was extended one hour until 5 p.m. local time. Results are constitutionally required to be announced in 48 hours.

In the morning, impatient crowds gathered outside polling stations expressing concerns over the delays. Umaru Mutyaba, a polling agent for a parliamentary candidate, said it was “frustrating” to be waiting outside a station in the capital Kampala.

“We can’t be standing here waiting to vote as if we have nothing else to do," he said.

Wine, the candidate, alleged electoral fraud, noting that biometric voter identification machines were not working at polling places and claiming that there was “ballot stuffing.”

Wine wrote in a post on X that his party's leaders had been arrested. “Many of our polling agents and supervisors abducted, and others chased off polling stations,” the post said.

Museveni told journalists he was notified that biometric machines weren't working at some stations and that he supported the electoral body's decision to revert to paper registration records. He did not comment on allegations of fraud.

Ssemujju Nganda, a prominent opposition figure and lawmaker seeking reelection in Kira municipality, told The Associated Press he had been waiting in line to vote for three hours.

Nganda said the delays likely would lead to apathy and low turnout in urban areas where the opposition has substantial support. "It’s going to be chaos,” he said.

Nicholas Sengoba, an independent analyst and newspaper columnist, said delays to the start of voting in urban, opposition areas favored the ruling party.

Emmanuel Tusiime, a young man who was among dozens prevented from entering a polling station in Kampala past closing time said the officials had prevented him from participating.

“My vote has not been counted, and, as you can see, I am not alone," he said he was left feeling “very disappointed.”

Uganda has not witnessed a peaceful transfer of presidential power since independence from British colonial rule six decades ago.

Museveni has served the third-longest term of any African leader and is seeking to extend his rule into a fifth decade. The aging president’s authority has become increasingly dependent on the military led by his son, Muhoozi Kainerugaba.

Museveni and Wine are reprising their rivalry from the previous election in 2021, when Wine appealed to mostly young people in urban areas. With voter turnout of 59%, Wine secured 35% of the ballots against Museveni’s 58%, the president’s smallest vote share since his first electoral campaign three decades ago.

The lead-up to Thursday's election produced concerns about transparency, the possibility of hereditary rule, military interference and possible vote tampering.

Uganda's internet was shut down Tuesday by the government communications agency, which cited misinformation, electoral fraud and incitement of violence. The shutdown has affected the public and disrupted critical sectors such as banking.

There has been heavy security leading up to voting, including military units deployed on the streets this week.

Amnesty International said security forces are engaging in a “brutal campaign of repression,” citing a Nov. 28 opposition rally in eastern Uganda where the military blocked exits and opened fire on supporters, killing one person.

Museveni urged voters to come out in large numbers during his final rally Tuesday.

“You go and vote, anybody who tries to interfere with your freedom will be crushed. I am telling you this. We are ready to put an end to this indiscipline,” he said.

The national electoral commission chairperson, Simon Byabakama, urged tolerance among Ugandans as they vote.

“Let us keep the peace that we have,” Byabakama said late Wednesday. “Let us be civil. Let us be courteous. Let’s be tolerant. Even if you know that this person does not support (your) candidate, please give him or her room or opportunity to go and exercise his or her constitutional right."

Authorities also suspended the activities of several civic groups during the campaign season. That Group, a prominent media watchdog, closed its office Wednesday after the interior ministry alleged in a letter that the group was involved in activities “prejudicial to the security and laws of Uganda.”
