Changjing · Bipolar (BJT) · SOT-223
CZT5401 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 | passive | Base terminal of the PNP transistor; the emitter-base voltage limit is -5 V (VEBO) and emitter-base breakdown is -5 V minimum at IE=-0.01mA. |
| 2 | COLLECTOR | passive | Collector terminal; limits are -160 V VCBO, -150 V VCEO, -600 mA IC, and 1 W collector power dissipation. |
| 3 | EMITTER | passive | Emitter terminal; the emitter-base voltage limit is -5 V (VEBO) with junction and storage range -55 to +150 ℃. |
