PZT4401

Changjing · Bipolar (BJT) · SOT-223

PZT4401 from Changjing, 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 BASE input Base terminal of the NPN transistor; the datasheet rates the emitter-base voltage VEBO at 6 V.
2 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet rates VCBO at 60 V, VCEO at 40 V, and collector current IC at 600 mA.
3 EMITTER passive Emitter terminal of the NPN transistor; the datasheet rates the emitter-base voltage VEBO at 6 V.
