MMDT5401DW from CBI, in a SOT-363. 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 | E1 | passive | Emitter of PNP transistor 1; emitter-base breakdown voltage is -5 V (VEBO). |
| 2 | B1 | passive | Base of PNP transistor 1; the saturation specs use IB = -1 mA to -5 mA. |
| 3 | C2 | passive | Collector of PNP transistor 2; VCEO is -150 V, VCBO is -160 V and IC is -600 mA max. |
| 4 | E2 | passive | Emitter of PNP transistor 2; emitter-base breakdown voltage is -5 V (VEBO). |
| 5 | B2 | passive | Base of PNP transistor 2; the saturation specs use IB = -1 mA to -5 mA. |
| 6 | C1 | passive | Collector of PNP transistor 1; VCEO is -150 V, VCBO is -160 V and IC is -600 mA max. |
