UMX2N
Changjing · Bipolar Transistors - BJT · SOT-363
UMX2N from Changjing, 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 the first NPN transistor (Tr1); the datasheet gives VEBO of 7 V maximum and IC of 150 mA maximum per transistor. |
| 2 | B1 | passive | Base of the first NPN transistor (Tr1); the datasheet gives VEBO of 7 V maximum with the emitter. |
| 3 | C2 | passive | Collector of the second NPN transistor (Tr2); the datasheet gives VCEO of 50 V, VCBO of 60 V and IC of 150 mA maximum. |
| 4 | E2 | passive | Emitter of the second NPN transistor (Tr2); the datasheet gives VEBO of 7 V maximum and IC of 150 mA maximum. |
| 5 | B2 | passive | Base of the second NPN transistor (Tr2); the datasheet gives VEBO of 7 V maximum with the emitter. |
| 6 | C1 | passive | Collector of the first NPN transistor (Tr1); the datasheet gives VCEO of 50 V, VCBO of 60 V and IC of 150 mA maximum. |
