BUK7508-55A,127

Overview

The BUK7508-55A is an N-channel TrenchMOS standard level FET designed for automotive critical applications. It features a drain-source voltage of 55 V and a continuous drain current of 75 A at a mounting base temperature of 25 °C. The device exhibits low on-state resistance, measuring 6.88 mΩ at 25 °C and 16 mΩ at 175 °C under specified conditions. Total power dissipation reaches 254 W at 25 °C. It includes avalanche ruggedness with a non-repetitive energy rating of 670 mJ.

Feature Summary

Low conduction losses due to low on-state resistance
Qualified according to AEC-Q101 for automotive use
Suitable for standard level gate drive sources
Operates in thermally demanding environments up to 175 °C

Applications

12 V and 24 V loads
Automotive systems
General purpose power switching
Motors, lamps and solenoids

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component for high-current switching applications requiring robust thermal performance and automotive qualification. Ensure the gate drive source aligns with standard level requirements. Verify that the mounting base temperature remains within limits to sustain the 75 A continuous current rating. Consider the package's thermal resistance when designing heat dissipation strategies for sustained operation.

Part Context
