SIP32431DR3-T1GE3

Overview

The Vishay Siliconix SIP32431DR3-T1GE3 is a P-channel MOSFET high-side load switch in a SC-70-6 surface-mount package. It supports an input voltage range of 1.5 V to 5.5 V and delivers a maximum continuous drain current of 1.2 A. The device features a typical on-resistance of 147 mΩ at 5 V. Key electrical characteristics include ultra-low leakage, a static current of 0.01 nA, and reverse current blocking capability. It operates within a temperature range of -40°C to +85°C with a power dissipation of 250 mW.

Feature Summary

• Slew rate controlled turn-on time for linear current rise
• Reverse current blocking functionality
• Ultra-low leakage and static current consumption
• Logic high-level enable control interface

Applications

• Battery-powered portable devices
• Power distribution in mobile systems
• Load switching for peripheral circuits
• High-side switching applications

Procurement Notes

Verify the specific suffix DR3 against the manufacturer datasheet to confirm the SC-70-6 package configuration. Ensure the T1 designation matches the required reel quantity specifications. Confirm RoHS compliance status and lead-free certification requirements prior to finalizing procurement orders for production integration.

Selection Notes

Select this component when low quiescent current and reverse blocking are critical for battery life extension. The 1.2 A current rating suits moderate load applications requiring controlled inrush current. Compare against SiP32411 for higher current needs or SiP32432 if logic low enable control is preferred over high-level activation.

Part Context

This part belongs to the SiP3243x series of high-side switches from Vishay Siliconix. It shares architectural similarities with the SiP32432 but differs in enable logic polarity. The series targets compact consumer electronics where space constraints and power efficiency are paramount design drivers.
