Changjing · Bipolar (BJT) · SOT-353
UMY1N from Changjing, in a SOT-353. 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 | B1 | input | Base of the left-hand transistor in the schematic (Tr1 PNP 2SA1037AK or Tr2 NPN 2SC2412K), with Tr1 limits of VEBO -6 V and IC -150 mA. |
| 2 | E | passive | Common emitter of the PNP and NPN transistors (shared between Tr1 and Tr2). |
| 3 | B2 | input | Base of the right-hand transistor in the schematic, with Tr2 limits of VEBO 7 V and IC 150 mA if NPN. |
| 4 | C2 | passive | Collector of the right-hand transistor in the schematic, with VCEO of 50 V (Tr2) or -50 V (Tr1) and IC of 150 mA max. |
| 5 | C1 | passive | Collector of the left-hand transistor in the schematic, with VCEO of 50 V (Tr2) or -50 V (Tr1) and IC of 150 mA max. |
