ZXTN2018FTA

Diodes Incorporated · Bipolar (BJT) · SOT-23

ZXTN2018FTA from Diodes Incorporated, 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 B input Base of the NPN transistor; VEBO is limited to 7 V and continuous base current IB to 1 A.
2 E passive Emitter of the NPN transistor; connects to the load return or ground in typical low-side switching.
3 C passive Collector of the NPN transistor; VCEO 60 V, VCBO 140 V, continuous IC 5 A and peak ICM 12 A.
