BUK9875-100A/CUX

Overview

The BUK9875-100A/CUX is an N-channel TrenchMOS logic level FET designed for automotive critical applications. It features a 100 V drain-source voltage rating and operates with a continuous drain current of 7 A at 25 °C solder point temperature. The device exhibits low on-state resistance, specified as a maximum of 84 mΩ at VGS = 4.5 V and ID = 8 A. Total power dissipation reaches 8 W at 25 °C. The component includes avalanche ruggedness capabilities with a non-repetitive energy rating of 49 mJ.

Feature Summary

Logic level gate drive compatibility
Automotive qualification compliant with AEC standards
Q101 compliance

Applications

12 V, 24 V and 42 V loads
Automotive power switching
General purpose power switching
Motor control
Lamp and solenoid driving

Procurement Notes

Verify the specific ordering suffix /CU against the manufacturer's current product data sheet to confirm package and marking details. Ensure the application environment remains within the specified junction temperature range of -55 °C to 150 °C. Confirm that thermal management strategies align with the provided thermal resistance values to maintain safe operating conditions during operation.

Selection Notes

Select this component when logic-level gate drive signals are available, as it supports full conduction at low gate voltages. The SC-73 (SOT223) package provides increased heatsink capability suitable for surface-mount designs. Verify that the required drain current does not exceed the 7 A limit under the expected thermal conditions of the final assembly.

Part Context

This part belongs to Nexperia's TrenchMOS family, utilizing trench technology to achieve low on-state resistance. The BUK9875-100A variant specifically targets high-voltage automotive applications requiring robust performance. The /CU suffix indicates the specific plastic surface-mounted package configuration with four leads in the SOT223 form factor.
