# DTC143EU3HZGT106

**ROHM Semicon** · Digital Transistors · SC-70

DTC143EU3HZGT106 from ROHM Semicon, in a SC-70. 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 | power_in | Ground, connected to the emitter of the built-in NPN transistor and to R2, which is 4.7kΩ (typ.). |
| 2 | IN | input | Input, connected to the base through the built-in 4.7kΩ (typ.) R1, with an absolute maximum input voltage of -10 to 30 V. |
| 3 | OUT | output | Output, connected to the collector of the built-in NPN transistor, rated for 100 mA output current and 50 V supply voltage maximum. |
