2SD1383KT146B

ROHM Semicon · Bipolar Transistors - BJT · TO-236-3(SOT-23-3)

2SD1383KT146B 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 Emitter passive Emitter of the Darlington pair, connected to the base through the built-in 4kΩ resistor; BVEBO is 6V min.
2 Base passive Base of the Darlington transistor, with a built-in 4kΩ resistor between base and emitter; VEBO max is 6V.
3 Collector passive Collector of the Darlington pair; VCBO is 40V, VCES is 32V and IC is 0.3A (ICP 1.5A pulsed).
