DTC143ZU3HZGT106

ROHM Semicon · Digital Transistors · SOT-323

DTC143ZU3HZGT106 from ROHM Semicon, in a SOT-323. 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 Ground / emitter of the built-in NPN transistor, connected to the R2 base-emitter resistor (47kΩ).
2 IN (BASE) input Input / base of the NPN digital transistor through built-in R1 = 4.7kΩ, with input voltage range -5 to 30 V, VI(off) max 0.5 V and VI(on) min 1.3 V.
3 OUT (COLLECTOR) output Output / collector of the NPN digital transistor, rated for VCC 50 V and output current up to 100 mA.
