DMP4026SFVW-13

Overview

The DMP4026SFVW is a P-channel enhancement mode MOSFET from Diodes Incorporated, rated for a drain-source voltage of -40 V. It offers a maximum on-resistance of 25 mΩ at VGS = -10 V and 45 mΩ at VGS = -4.5 V. The device supports continuous drain currents of -49 A at TC = +25°C and -8.9 A at TA = +25°C. Packaged in a PowerDI3333-8 surface-mount format, it features a total gate charge of 45.8 nC at VGS = -10 V and operates within a junction temperature range of -55 to +150 °C.

Feature Summary

• Low on-state resistance ensures minimal power losses during conduction.
• Small form factor thermally efficient package enables higher density end products.
• Occupies just 33% of the board area occupied by SO-8 packages.
• 100% unclamped inductive switch (UIS) tested in production.

Applications

• Reverse-polarity protections
• Power-management functions
• DC-DC converters

Procurement Notes

Verify the specific ordering suffix matches the required packaging quantity; the -13 suffix indicates a 3000-unit tape and reel carrier. Confirm compliance with RoHS 2, RoHS 3, and halogen-free requirements if mandated by your design specifications. Ensure the selected component aligns with automotive quality standards only if explicitly requested through authorized channels.

Selection Notes

Select this component when designing high-efficiency power management circuits requiring low on-state resistance and superior switching performance. Evaluate thermal constraints carefully, as the device's power dissipation capabilities depend heavily on the PCB copper area and mounting method. Verify that the gate drive voltage meets the minimum threshold for optimal RDS(ON) reduction.

Part Context

This part belongs to the DMP4026 series of P-channel MOSFETs manufactured by Diodes Incorporated. It utilizes the PowerDI3333-8 package, which provides a compact footprint suitable for space-constrained applications. The series is designed to minimize on-state resistance while maintaining robust switching characteristics for modern electronic systems.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Do not assume cross-compatibility based solely on similar voltage or current ratings without verifying pinout and electrical parameter alignment.
