A733-MS

MSKSEMI · Bipolar Transistors - BJT · SOT-23

A733-MS from MSKSEMI, in a SOT-23. 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 PNP transistor, with base-emitter voltage VBE(on) of -0.58 to -0.68 V at VCE=-6V and IC=-1mA.
2 EMITTER passive Emitter terminal of the PNP transistor, with emitter-base breakdown voltage V(BR)EBO of -5 V minimum at IE=-50uA.
3 COLLECTOR passive Collector terminal of the PNP transistor, rated for collector-base voltage VCBO of -60 V and continuous collector current IC of -150 mA.
