Taiwan Semiconductor, a global supplier of discrete power electronics devices, LED drivers, analog ICs and ESD devices, has expanded its PerFET family of power MOSFETs with the addition of 80 V and 100 V versions. Based on TSC’s proprietary PerFET device structures and processes, the new 80 V/100 V N-channel power MOSFETs offer a best-in-class figure of merit (FOM: R_DS(on)*Q = 184) and an industry-leading 175°C avalanche rating. The AEC-Q-qualified devices are ideal for automotive power applications—and myriad non-automotive commercial and industrial power applications that demand efficient, reliable performance.

PerFET devices are housed in TSC-designed, industry-standard-size (5 mm x 6 mm) PDFN56U (single/dual) packages whose wettable flank improves solder joint reliability and AOI accuracy during PCB assembly. The PerFETs’ low on-resistance (R_DS(on)) reduces conduction losses and their very low gate charge (Q_g) - optimized for high-speed communication applications - offers the most efficient solution available for 48 V input DC/DC converters.

Six devices comprise the new 100 V PerFET series, with single-output current ratings of 50 - 100 A and dual-outputs rated at 31 A. Target applications are 48 V automotive, SMPS, server and telecom, DC-DC converters, motor drives, and polarity switches. The new 80 V PerFET series also offers six devices. Single-output models feature current ratings of 33 - 110 A and 31 - 33 A for dual-output models. In addition to those targeted by the 100 V series, 80 V PerFETs are suitable for ideal diodes, USB-PD and type-C chargers/adapters, UPS, solar inverters, LED lighting, and telecommunications power applications.

“Because our PerFET power MOSFETs are built to automotive standards, design engineers can use them to achieve automotive-grade reliability in competitively priced, non-automotive applications - while eliminating proof-of-qualification paperwork necessary when using automotive parts,” said Sam Wang, vice president, TSC Products. “By adding 80- and 100-volt devices to our PerFET family, designers have even more options for increasing efficiency and reliability in their power-switching applications.
