SI9706DY-E3

Overview

The SI9706DY-E3 is a specialized PC Card Interface Switch manufactured by Vishay Siliconix. It is designed for managing power and control signals in PCMCIA applications. The component operates within a temperature range of -40°C to +85°C and utilizes an SOIC-Narrow-8 surface-mount package. Key electrical parameters include a maximum operating voltage of 15 V and a typical on-resistance of 0.25 Ohms. The device supports single-supply operation and features low leakage current characteristics suitable for portable electronics.

Feature Summary

Integrated switching capability for PCMCIA interface power management
Low on-resistance for efficient signal transmission
Compact SOIC-Narrow-8 surface-mount packaging

Applications

PCMCIA card slot power control
Portable computer peripheral interfaces
Battery-powered device I/O protection

Procurement Notes

Verify the End-of-Life status with the manufacturer before design finalization, as this component may be discontinued. Confirm RoHS compliance documentation availability for regulatory requirements. Ensure the SOIC-Narrow-8 footprint matches your PCB layout constraints. Check for any specific handling precautions related to the legacy silicon process used in this part number.

Selection Notes

Select this component only if PCMCIA compatibility is required. Compare the 0.25 Ohm on-resistance against system voltage drop limits. Verify that the 15 V maximum rating exceeds your circuit's peak voltages. Consider the thermal performance in the SOIC-8 package under continuous load conditions.

Part Context

This part belongs to the Vishay Siliconix interface switch family, specifically tailored for legacy PC Card standards. It serves as a bridge between host controllers and expansion cards. The E3 suffix indicates lead-free composition compliant with environmental directives. It replaces older discrete switching solutions in compact form factors.
