2SC3357-E

KEXIN · Bipolar (BJT) · SOT-89

2SC3357-E from KEXIN, in a SOT-89. 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 Base input Base terminal of the NPN transistor; emitter-base voltage is rated at VEBO 3 V maximum, with IE = 100 µA used for the breakdown test.
2 Collector passive Collector terminal; rated at VCBO 20 V and VCEO 12 V maximum, with continuous collector current IC of 100 mA maximum.
3 Emitter passive Emitter terminal of the NPN transistor, referenced in the emitter-base breakdown and cut-off test conditions (VEB = 3 V).
