BUK7908-40AIE,127

Overview

The BUK7908-40AIE is an N-channel TrenchPLUS standard level FET utilizing TrenchMOS technology in a TO-220 plastic package. It features integrated current sensing and ESD protection diodes, designed for automotive critical applications compliant with AEC-Q101. Key electrical parameters include a drain-source voltage of 40 V, continuous drain current up to 117 A at 25 °C mounting base temperature, and a typical on-state resistance of 68 mΩ at 25 °C. The device supports a junction temperature range from -55 °C to +175 °C.

Feature Summary

Integrated current sensing capability reduces component count
Electrostatically robust design with built-in protection diodes
Low conduction losses achieved through low on-state resistance
Qualified for automotive critical applications per AEC-Q101 standards

Applications

Electrical Power Assisted Steering (EPAS)
Variable Valve Timing for engines

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the intended application environment falls within the specified thermal limits and does not exceed absolute maximum ratings. Ensure compatibility with standard level gate drive sources as indicated in the product profile. Check for any recent Product Change Notifications regarding manufacturing site or material updates.

Selection Notes

Select this component when high current handling and precise current monitoring are required in automotive systems. The TO-220 package facilitates heatsink mounting for effective thermal management. Consider the 68 mΩ on-resistance for efficiency calculations. Verify that the 40 V rating aligns with the system's maximum operating voltage under all transient conditions.

Part Context

This part belongs to Nexperia's TrenchPLUS family of N-channel MOSFETs. These devices combine standard logic-level gate drive compatibility with advanced trench technology for improved performance. The inclusion of Kelvin source and dedicated sense pins distinguishes it from standard power MOSFETs by enabling accurate current feedback without external shunt resistors.
