CMBT4401 Description

Short technical summary and product information.

The CMBT4401 is an NPN small signal transistor manufactured by Continental Device India Ltd (CDIL). It is designed for general purpose amplification and switching applications, handling collector currents up to 500 mA.

 

Key electrical characteristics include a collector-emitter voltage (VCEO) of 40V and a collector-base voltage (VCBO) of 60V. The device offers a DC current gain (hFE) ranging from 40 to 500, and a gain-bandwidth product (fT) of 200 MHz. Its complementary PNP type is the CMBT4403.

 

Packaged in a compact SOT-23 surface mount package, the CMBT4401 is suitable for space-constrained designs. It operates within a junction temperature range of -55 to 150°C and has a total power dissipation of 600mW at 25°C ambient.

 

This transistor is ideal for medium power amplification and switching tasks in various electronic circuits.
