SI1040X-T1-GE3

Overview

The SI1040X-T1-GE3 is a P-channel MOSFET from the Vishay Siliconix TrenchFET series, housed in an SC-89 (SOT-563F) surface-mount package. It features a drain-source voltage (Vds) of -8 V and a continuous drain current (Id) of 890 mA at ambient temperature. The device exhibits a maximum on-resistance (Rds(on)) of 890 mΩ at a gate-source voltage (Vgs) of -2.5 V. Power dissipation is rated at 236 mW, with an operating junction temperature range spanning from -55°C to +150°C.

Feature Summary

• Utilizes TrenchFET technology for optimized power switching performance.
• Integrated level-shift capability suitable for load switch applications.
• Compact SC-89 surface-mount package design.

Applications

• Portable battery-powered equipment
• Load switching circuits

Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications against the official manufacturer datasheet prior to procurement. Confirm that the component meets all required environmental compliance standards for the intended deployment environment. Ensure that static-sensitive handling procedures are strictly followed during storage and assembly to prevent electrostatic discharge damage to the semiconductor structure.

Selection Notes

Select this component when a low-voltage P-channel switch is required for space-constrained designs. The SC-89 package offers a small footprint compared to larger SO-8 alternatives. Evaluate the thermal constraints carefully, as the 236 mW power dissipation rating limits high-current continuous operation. Verify that the -8 V drain-source voltage rating exceeds the maximum circuit potential to ensure reliable blocking performance under all operating conditions.

Part Context

This part belongs to the SI1040X family of low-voltage P-channel MOSFETs designed for portable electronics. The TrenchFET process enables improved figure-of-merit characteristics relative to standard planar technologies. The SC-89 package provides a compact solution for modern printed circuit board layouts requiring minimal surface area occupation while maintaining adequate electrical isolation.

Replacement Considerations

Consult official substitution guides for verified equivalents. Cross-reference pinouts and electrical parameters before integrating alternative components into existing designs.
