MPSA13-TA
Changjing · Bipolar (BJT) · TO-92
MPSA13-TA from Changjing, in a TO-92. 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 | EMITTER | passive | Emitter of the NPN Darlington transistor; the emitter-base breakdown voltage V(BR)EBO is 10 V minimum at IE=0.1 mA. |
| 2 | BASE | passive | Base of the NPN Darlington transistor; base-emitter voltage VBE is 2.0 V at VCE=5 V and IC=100 mA. |
| 3 | COLLECTOR | passive | Collector of the NPN Darlington transistor; rated 30 V collector-emitter voltage, 0.5 A continuous collector current and 625 mW collector power dissipation. |
