DP350T05-7

Diodes Incorporated · Bipolar (BJT) · SOT-23

DP350T05-7 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 input Base of the PNP transistor; emitter-base voltage limit is -5.0 V (VEBO).
2 E passive Emitter of the PNP transistor; emitter-base breakdown V(BR)EBO is -5.0 V min at IE = -10 µA.
3 C passive Collector of the PNP transistor; rated VCBO and VCEO of -350 V and continuous collector current of -500 mA.
