Product Type: Power MOSFET

Taiwan Semiconductor, a global supplier of discrete power electronics devices, LED drivers, analog ICs, and ESD protection devices, announces the introduction of the TQM Family of single and dual N-channel automotive grade power MOSFETs. Offered with drain-to-source breakdown voltage (BVDSS) of either 40V or 60V, all of the 14 parts in this AEC-Q101 family feature a maximum operating temperature (Tj) of 175° C. Unlike many other products in this class, all are 100% tested for compliance with a published maximum resistance and UIS/Avalanche rating. The devices are all packaged in an industry-compatible, wettable flank, 5×6 mm PDFN package.

The TQM Family offers designers a number of benefits and some improvements over competing devices:

• 100% UIS/Avalanche Ratings Compliance. Provides assurance of consistent safe operating area (SOA)
• RDS(ON), Max. Guaranteed. 100% testing for compliance with published specs allows the design to have tighter margins
• AEC-Q101 Certification. Assures proven quality and reliability in critical transportation electronics and other high-reliability applications
• 175°C Tj, Max. Essential for many automotive applications.
• Wettable Flank Packaging. Facilitate lower cost manufacturing (AOI vs X-Ray inspection) and offer higher production yields
• Product Part Approval Process (PPAP). Taiwan Semiconductor MOSFET fabrication facilities meet the most stringent AEC standards and PPAP documentation is available on request.

“The TQM Family combines Taiwan Semiconductor’s MOSFET technology expertise with innovative, wettable flank packaging to offer automotive power electronics designers with exceptional value,” reported Sam Wang, Vice President, TSC Products.
