2SC2411KT146Q

2SC2411KT146Q is an NPN bipolar transistor in the 2SC family. The KT146Q suffix is a vendor/packaging/date code, so exact electrical ratings depend on the manufacturer. It’s used for general-purpose amplification and switching in small-signal and RF circuits.
Key takeaways:
- Package and pinout vary by vendor (check exact datasheet for your device).
- Typical roles: small-signal amplification, driver stages, switching.
- Typical specs you may see (varies by variant): Vceo ~60–100 V; Ic up to tens of mA (often 50–100 mA); hFE ~100–300; fT in the hundreds of MHz.
- Always consult the specific datasheet (e.g., from DigiKey/Mouser or the manufacturer) for exact ratings, pinout, and safe operating area.
If you have a particular manufacturer or package, I can pull the exact datasheet details.

I don’t have live lookup access. To give accurate equivalents I need the chip’s key specs (polarity, Vce max, Ic max, hFE, package and intended application). Please paste the 2SC2411KT146Q datasheet or those parameters and I’ll list pin‑compatible substitutes and commonly used equivalents.

2SC2411KT146Q is an NPN silicon small‑signal transistor in an SMD package. Key features (typical, per datasheet standards) include:
