2SD1816L-R-TN3-R

UTC(Unisonic Tech) · Bipolar Transistors - BJT · TO-252

2SD1816L-R-TN3-R from UTC(Unisonic Tech), in a TO-252. 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 B input Base of the NPN transistor; emitter-base voltage VEBO max 6 V.
2 C passive Collector of the NPN transistor; VCBO 120 V, VCEO 100 V, IC 4 A DC (8 A pulse).
3 E passive Emitter of the NPN transistor; current return for the collector current.
