SQ3985EV-T1_BE3

Overview

The SQ3985EV-T1_BE3 is an automotive-grade dual P-channel MOSFET from Vishay Siliconix, utilizing TrenchFET technology. It features a -20 V drain-source voltage and a continuous drain current of -3.9 A at 25 °C. The device operates within a junction temperature range of -55 °C to +175 °C. Key electrical parameters include a maximum on-resistance of 0.145 Ω at VGS = -4.5 V and 0.200 Ω at VGS = -2.5 V. Total gate charge is typically 3.1 nC at VGS = -4.5 V. It is housed in a TSOP-6 surface-mount package.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
TrenchFET power MOSFET architecture for optimized performance
100% tested for RDS(on) and single-pulse avalanche energy

Applications

Automotive load switching applications
High-side power control circuits
Low-voltage DC-DC converter input stages

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance with halogen-free requirements and lead finish specifications. Ensure that the component marking code matches the datasheet reference before integration into production assemblies.

Selection Notes

Select this component when a dual P-channel configuration is required in a compact TSOP-6 footprint. Evaluate thermal management requirements based on the specified junction-to-foot resistance and ensure the gate drive voltage meets the minimum threshold for the desired on-state resistance level.

Part Context

This part belongs to the SQ series of automotive MOSFETs manufactured by Vishay Siliconix. It shares the TSOP-6 package form factor with other devices in the lineup but is distinguished by its specific -20 V rating and dual-channel topology designed for space-constrained automotive electronics.
