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). |
