BF620

Nexperia · Bipolar (BJT) · SOT-89

BF620 from Nexperia, in a SOT-89. 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 E passive Emitter of the NPN transistor; the emitter-base voltage is limited to 5 V (VEBO).
2 C passive Collector of the NPN transistor; limited to 300 V collector-emitter (VCEO) and 50 mA collector current (IC), and the collector pad is the thermal reference for the mounting-pad derating figures.
3 B passive Base of the NPN transistor; peak base current is limited to 50 mA (IBM, single pulse, tp ≤ 1 ms).
