FMMT495TC

Diodes Incorporated · Bipolar Transistors - BJT · SOT-23

FMMT495TC from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B passive Base takes a base current IB rated at 200 mA maximum, and VBE(ON) is specified at 1.0 V maximum with IC = 500mA and VCE = 10V.
2 E passive Emitter is the reference terminal for the 7 V emitter-base breakdown rating (BVEBO) and for the VCE(SAT) limits of 0.2 V at 250mA and 0.3 V at 500mA.
3 C passive Collector carries 1 A continuous and 2 A peak pulse current (ICM) with a collector-emitter voltage rating of 150 V (VCEO).
