DTD143ECHZGT116

ROHM Semicon · Bipolar Transistors - BJT · SOT-23

DTD143ECHZGT116 from ROHM Semicon, in a SOT-23. 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 R2 of the inner circuit.
2 IN (BASE) input Input/base pin through built-in R1 of 4.7kΩ, with input voltage rated -10 to 30 V and VI(off) max 0.5 V, VI(on) min 3.0 V.
3 OUT (COLLECTOR) output Output/collector pin rated 50 V supply voltage and 500 mA collector current, with VO(on) max 300 mV at IO = 50 mA.
