PZT1816G-S-AA3-R

UTC Unisonic Tech · Bipolar (BJT) · SOT-223

PZT1816G-S-AA3-R from UTC Unisonic Tech, in a SOT-223. 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 terminal of the NPN transistor; the datasheet rates emitter-base voltage VEBO at 6 V, with BVEBO tested at IE = 10 µA.
2 C passive Collector terminal; absolute maximum ratings are VCBO 120 V, VCEO 100 V, and DC collector current IC 4 A (8 A pulse, duty 1/2, Pw 20 ms).
3 E passive Emitter terminal; the datasheet rates emitter-base voltage VEBO at 6 V.
