onsemi · Digital Transistors · SOT-23
MMUN2211LT3G from onsemi, 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 (input) terminal of the bias resistor transistor, which has a series input resistor R1 of 10 kΩ; the datasheet limits input forward voltage to 40 Vdc and input reverse voltage to 10 Vdc. |
| 2 | EMITTER | power_in | Emitter, labeled GROUND on the datasheet, serving as the common reference for the monolithic base-emitter bias resistor R2 of 10 kΩ. |
| 3 | COLLECTOR | output | Collector (output) terminal, rated for a collector-emitter voltage VCEO of 50 Vdc and continuous collector current IC of 100 mAdc. |
