RN1404

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

RN1404 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 the built-in 47 kΩ bias resistor R1 (RN1404); VI(ON) 1.3 to 5.0 V range per datasheet table, VEBO max 10 V.
2 Emitter passive Emitter terminal of the NPN transistor, connected to ground in typical switching use; R2 (47 kΩ) sits between base and emitter.
3 Collector passive Collector terminal with VCEO max 50 V and IC max 100 mA.
