SPZT2907AT1G

onsemi · Bipolar Transistors - BJT · SOT-223-4

SPZT2907AT1G from onsemi, in a SOT-223-4. 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 BASE passive Base terminal of the PNP epitaxial transistor; the datasheet gives emitter-base breakdown V(BR)EBO of −5.0 Vdc minimum and a maximum emitter-base rating VEBO of −5.0 Vdc.
2 COLLECTOR passive Collector terminal (electrically tied to pin 4 and the tab); the datasheet rates collector-emitter voltage VCEO at −60 Vdc and continuous collector current IC at −600 mAdc.
3 EMITTER passive Emitter terminal of the PNP transistor; the emitter-base rating is VEBO −5.0 Vdc.
4 COLLECTOR passive Collector terminal (electrically tied to pin 2 and the tab); the datasheet rates collector-emitter voltage VCEO at −60 Vdc and continuous collector current IC at −600 mAdc.
