Small-signal automotive mosfets

Taiwan Semiconductor has introduced ten AEC-Q101-qualified small-signal mosfets.

There are seven n-channel parts (including two duals), and three p-channel parts (one dual) in the ‘TQM’ line – see the table below.

Three packages are used: SOT-236, SOT-363 or SOT-323, and they are rated for >2kV ESD withstanding.

“In addition to automotive applications, these small-footprint MOSFETs are ideal for high-reliability commercial designs requiring automotive-grade levels of protection,” said the company. “Typical applications include switching circuits, high-speed line drivers, low-side load switching, relay drivers, and amplification.”

A trench structure is used, and they are made at the company’s IATF 16949-certified facilities.

J-STD-020 (level 1) is met for moisture sensitivity, and they are are halogen-free and RoHS compliant, with an optional PPAP.
