BUK9E06-55B Description

Short technical summary and product information.

The BUK9E06-55B from Infineon is an N-channel enhancement mode Field-Effect Transistor (FET) utilizing TrenchMOS technology, packaged in a plastic SOT226 (I2PAK) for surface mounting. This device is designed and qualified for automotive critical applications, making it suitable for 12 V and 24 V loads, general purpose power switching, and driving motors, lamps, and solenoids.

 

Key electrical characteristics include a maximum drain-source voltage (VDS) of 55 V and a continuous drain current (ID) of up to 75 A at 25°C ambient temperature with a VGS of 5V. The on-state resistance (RDSon) is as low as 4.85 mOhm at VGS = 10V and 25A, and 5.16 mOhm at VGS = 5V and 25A, contributing to low conduction losses. The FET is rated for a maximum junction temperature of 175°C, making it suitable for thermally demanding environments.

 

This product is Q101 compliant and suitable for logic level gate drive sources. Its avalanche ruggedness is demonstrated by a non-repetitive drain-source avalanche energy (EDS(AL)S) of 679 mJ under specified conditions.
