Taiwan Semi’s New 1,200V Automotive-Grade Low-Loss Diodes Offered in Three Package Sizes

Taiwan Semi is introducing a new series of automotive-grade, 1200V PLA/PLD low-loss diodes offered in industry-standard packages

BREA, CA, UNITED STATES, October 30, 2025 /EINPresswire.com/ -- Taiwan Semiconductor, global supplier of discrete power electronics devices, LED drivers, analog ICs, TVS and ESD protection, introduces a new series of automotive-grade, low-loss diodes offered in industry-standard packages. The 1,200V PLA/PLD series, with ratings of 15A, 30A or 60A, all feature low forward voltage (1.3Vf max), low reverse leakage (<10µA at 25 degrees C) and high junction temperature (175C Tj Max). Available in three popular packages (ThinDPAK, D2PAK-D and TO-247BD), the new 1,200V diodes enable easy drop-in replacement to improve efficiency in existing designs.

Applications benefiting from the efficiencies provided by these new low-loss diodes include: three-phase AC/DC converters, server and computing power (including AI power) systems, EV charging stations, on-board battery chargers, Vienna rectifiers, totem pole and bridgeless topologies, inverters and UPS systems, and general-purpose rectification in high-power systems of various types. The 1,200V PLA/PLD series is offered in six models produced to stringent automotive-quality standards. Two models (PLAD15QH, PLDS30QH) are fully AEC-Q qualified for automotive applications.

“Our new automotive-grade 1,200V diodes increase efficiency by dropping into existing applications using an industry standard pinout,” said Sam Wang, vice president, TSC Products. “Their low loss also makes sure new designs and applications can take advantage of the lower power dissipation, including a wide range of power electronics applications where performance and reliability are critical.”

Available Now: Samples: In-stock (DigiKey and Mouser)
Lead Time: Production Quantities: 8-14 weeks (ARO)
Design resources include comprehensive datasheets, spice models, Foster and Cauer thermal models and CAD files (symbol, footprint, 3D model).
