BUK9237-55,118

Overview

The BUK9237-55,118 is an N-channel TrenchMOS logic level FET manufactured by NXP Semiconductors. It utilizes TrenchMOSTM1 technology to achieve very low on-state resistance. The device is housed in a DPAK (SOT428) plastic package and is rated for a drain-source voltage of 55V and a continuous drain current of 32A. This component is currently obsolete and no longer manufactured.

Feature Summary

N-channel enhancement mode field-effect power transistor
TrenchMOS logic level technology for low gate charge
Very low on-state resistance characteristics

Applications

Bosch EDC17C60 Engine Control Unit (ECU)
Automotive engine management systems
Power switching applications requiring logic level drive

Procurement Notes

This part number is officially classified as obsolete by the manufacturer. Direct procurement from NXP is not possible. Buyers must verify the authenticity and condition of available stock from third-party distributors or surplus suppliers. Ensure that any sourced units are genuine components and check for potential cross-references with newer generation equivalents if long-term supply stability is required.

Selection Notes

Select this component only for legacy designs where the specific electrical characteristics and pinout are critical. Due to its obsolete status, alternative sourcing carries higher risk. Engineers should evaluate modern replacements with similar voltage ratings and current capabilities that offer better availability. Verify that the replacement supports the same logic level gate drive requirements to maintain circuit compatibility without redesign.

Part Context

The BUK9237 series belongs to NXP's TrenchMOS family, designed for automotive and industrial power switching. These devices integrate advanced trench gate technology to minimize conduction losses. The specific -55 variant targets low-voltage applications, offering a balance between current handling capacity and thermal performance in compact surface-mount packages suitable for high-density PCB layouts.
