DTB114ECHZGT116 from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 | Emitter of the built-in PNP transistor, used as the GND (+) reference; the datasheet gives VCC of -50V and IC(MAX) of -500mA for the part. |
| 2 | IN (BASE) | input | Base input through built-in R1 = 10kΩ, with R2 = 10kΩ to the emitter; input voltage range is -40 to 10V, VI(off) max -0.5V and VI(on) min -3.0V. |
| 3 | OUT (COLLECTOR) | output | Collector output of the built-in PNP transistor, rated for IC(MAX) of -500mA and VCC of -50V, with VO(on) max -300mV at IO = -50mA. |
