MUN5232T1G from onsemi, in a SC-70-3. 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 | Input pin connected to the base through the integrated series bias resistor R1 (4.7 kΩ); input forward voltage is rated 30 Vdc and input reverse voltage 10 Vdc. |
| 2 | EMITTER | power_in | Emitter, labelled GROUND in the datasheet pin connections; the integrated base-emitter resistor R2 (4.7 kΩ) is connected between base and emitter. |
| 3 | COLLECTOR | output | Output pin; collector-emitter voltage is rated 50 Vdc and continuous collector current 100 mAdc. |
