BCR400W Description

Short technical summary and product information.

The Infineon BCR400W is an active bias controller designed to provide a stable bias current across varying battery voltages and ambient temperatures. It is particularly useful for stabilizing the bias current of NPN transistors and FETs, with applications ranging from less than 0.2mA up to more than 200mA.

Key electrical characteristics include a maximum source voltage of 18V and a maximum control current of 10mA. The device exhibits a low voltage drop of 0.65V at 25mA collector current. It also offers a low quiescent current of 20-40µA at 3V source voltage and a minimum stabilizing current of 0.1mA.

The BCR400W is housed in a SOT343 package and is suitable for surface mount applications. Its ability to maintain stable bias current makes it an ideal supplement for various transistor types and can also function as a current source up to 5mA.

This component is qualified according to AEC Q101, indicating its suitability for demanding applications. The Pb-free (RoHS compliant) package is standard, with Pb-containing options available upon special request.
