SST174-E3

Overview

The SST174-E3 is a small signal field-effect transistor manufactured by Vishay Siliconix. It is a single-element, P-channel silicon junction FET housed in a lead-free TO-236AB (SOT-23) package with three pins. The component is designed for general-purpose switching and amplification applications requiring low power consumption and high input impedance characteristics typical of MOSFET technology.

Feature Summary

• P-channel silicon construction for complementary circuit designs
• Lead-free compliant packaging meeting environmental standards
• Compact surface-mount form factor for space-constrained layouts

Applications

• General-purpose low-power switching circuits
• Battery-powered device management systems
• Signal amplification stages

Procurement Notes

Verify the specific datasheet revision and electrical parameter limits against current Vishay documentation before integration. Confirm that the TO-236AB package dimensions align with the target PCB footprint. Ensure thermal management requirements are met for the intended operating environment to maintain reliability.

Selection Notes

Select this component when a P-channel enhancement-mode MOSFET is required in a compact SOT-23 package. Evaluate threshold voltage and on-resistance specifications against the load requirements. Consider the lead-free RoHS compliance status if environmental regulations apply to the final assembly.

Part Context

This part belongs to the Vishay Siliconix discrete semiconductor portfolio, specifically within the small signal field-effect transistor category. It serves as a fundamental active component for analog and digital logic interfaces where efficient control of current flow is necessary in minimal physical space.
