2SC2411KT146Q

The 2SC2411KT146Q is an NPN bipolar junction transistor manufactured by ROHM Semiconductor, part of the 2SC2411K series. It is designed for medium-power switching and amplification applications, with a maximum collector-emitter voltage of 32V and a maximum collector current of 500mA. The device dissipates up to 200mW and operates at junction temperatures up to 150°C.

Key electrical characteristics include a DC current gain (hFE) ranging from 82 to 390 at VCE=3V and IC=100mA, with a minimum gain of 120 for this specific rank (Q). The collector-emitter saturation voltage is a maximum of 600mV at IC=500mA and IB=50mA, enabling efficient low-voltage operation. The transition frequency is typically 250MHz, and output capacitance is typically 6.5pF.

The transistor is housed in a surface-mount SMT3 package (also known as SOT-346 or TO-236-3/SC-59/SOT-23-3), with a supplier device package designation of SMT3. It is supplied on 180mm reels with 8mm tape width, with a basic ordering unit of 3000 pieces. The device is complementary to the 2SA1036K PNP transistor.

Typical applications include driving circuits and low-frequency amplifiers, where its high current capability and low saturation voltage are advantageous. The surface-mount package makes it suitable for automated assembly in compact electronic designs.
