PZTA42G

UTC Unisonic Tech · Bipolar (BJT) · SOT-223

PZTA42G from UTC Unisonic Tech, in a SOT-223. 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 of the NPN transistor; the datasheet rates the emitter-base voltage VEBO at 6 V (absolute maximum).
2 C passive Collector of the NPN transistor; rated for VCEO 300 V (PZTA42), collector current IC 500 mA and collector power dissipation PC 1 W.
3 E passive Emitter of the NPN transistor; the reference terminal for the 6 V emitter-base rating (VEBO).
