BUK9880-55A/CUX

Overview

The BUK9880-55A/CUX is an N-channel TrenchMOS logic level FET in a SOT223 package. It features a drain-source voltage of 55 V and a continuous drain current of 7 A at 25 °C solder point temperature. The device exhibits a typical on-state resistance of 68 mΩ at VGS = 5 V and ID = 8 A. Total power dissipation is rated at 8 W. Thermal resistance from junction to solder point is 15 K/W. Gate-source threshold voltage ranges from 1 V to 2.3 V. Avalanche energy capability is 36 mJ.

Feature Summary

Low conduction losses due to low on-state resistance
Qualified for automotive critical applications per AEC-Q101 standard
Suitable for logic level gate drive sources

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component status remains active or qualified for new designs. Check for any recent product change notices regarding marking codes or internal die revisions. Ensure the supplier provides valid traceability documentation for automotive grade compliance.

Selection Notes

Select this component for circuits requiring logic level gate compatibility with low RDS(on). Consider the thermal resistance characteristics when designing heat sinking solutions. Verify that the operating junction temperature stays within the specified -55 °C to 150 °C range. Evaluate the avalanche ruggedness if the application involves inductive load switching without clamping.
