ROHM Semicon · Digital Transistors · SOT-323
DTC143ZU3T106 from ROHM Semicon, in a SOT-323. 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 | GND (EMITTER) | power_in | Ground/emitter terminal of the built-in NPN transistor; R2 (47kΩ) connects between this pin and the input. |
| 2 | IN (BASE) | input | Input/base terminal through built-in R1 = 4.7kΩ; input voltage range -5 to 30 V, VI(off) max 0.5 V and VI(on) min 1.3 V. |
| 3 | OUT (COLLECTOR) | output | Output/collector terminal; supply voltage VCC max 50 V and output current IO max 100 mA. |
