RN1403

TOSHIBA · Digital Transistors · TO-236-3(SOT-23-3)

RN1403 from TOSHIBA, 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 Base input Base input through built-in bias resistor R1 = 22 kΩ (typ.) with R2 = 22 kΩ to emitter; VEB max 10 V.
2 Emitter passive Emitter terminal of the NPN transistor, typically connected to ground.
3 Collector passive Collector terminal of the NPN transistor; VCEO max 50 V and IC max 100 mA.
