2SC4081T106Q

Single Bipolar Transistors Overview

The 2SC4081T106Q is an NPN silicon general-purpose small signal amplifier transistor manufactured by ROHM Semiconductor. It operates with a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 150 mA, supporting a single pulse current of 200 mA. The device features a transition frequency (fT) of 180 MHz and a maximum power dissipation (PD) of 200 mW in the SOT-323 package. DC current gain (hFE) ranges from 120 to 560 depending on the rank, with a typical output capacitance (Cob) of 2.0 pF.
