Slkor SLKORMICRO Elec · Bipolar (BJT) · SOT-323

2SC4901 from Slkor SLKORMICRO Elec, in a SOT-323. 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 planar NPN high-frequency low-noise transistor; the datasheet gives no separate pin-level electrical limit for this pin, and the device absolute maximum ratings apply (VEBO 1.5 V, IC 50 mA, PC 100 mW).
2 Emitter passive Emitter terminal of the transistor; the datasheet gives no separate pin-level electrical limit for this pin, and the device absolute maximum ratings apply (VCBO 15 V, VCEO 9 V, IC 50 mA).
3 C passive Collector terminal of the transistor; the datasheet gives no separate pin-level electrical limit for this pin, and the device absolute maximum ratings apply (VCBO 15 V, VCEO 9 V, IC 50 mA, PC 100 mW).
