TPM2102BC3

TECH PUBLIC · MOSFETs · SOT-323

TPM2102BC3 from TECH PUBLIC, in a SOT-323. 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	G	input	Gate terminal of the N-channel MOSFET, with a gate-source voltage limit of VGS ±10 V.
2	S	passive	Source terminal of the N-channel MOSFET; the datasheet gives no separate pin-level limit beyond the device ratings of VDS 20 V and ID 2.5 A.
3	D	passive	Drain terminal of the N-channel MOSFET, rated for a drain-source voltage of 20 V and a continuous drain current of 2.5 A at TA=25°C (steady state).
