DG309BDY-T1-E3

Overview

The DG309BDY-T1-E3 is a quad single-pole single-throw (SPST) normally closed analog switch manufactured by Vishay Siliconix. It operates on dual supplies ranging from ±4 V to ±22 V or a single supply of 4 V to 44 V. The device features a maximum drain-source on-resistance of 85 Ω at room temperature and ±15 V supplies, with a turn-on time of 200 ns and turn-off time of 150 ns under dual supply conditions. Power dissipation in the 16-pin narrow SOIC package is rated at 640 mW. Operating temperatures span from -40 °C to +85 °C.

Feature Summary

Normally closed configuration for digital control applications
CMOS compatible logic interface
Low charge injection design minimizes switching transients
Epitaxial layer prevents latchup

Applications

Sample-and-hold circuits
Industrial instrumentation
Test equipment
Communications systems

Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation as required by project specifications. Ensure the narrow SOIC-16 footprint matches the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring normally closed signal paths controlled by standard CMOS logic levels. Verify that the maximum on-resistance of 85 Ω meets the signal integrity requirements of the circuit. Consider the power dissipation limits of the SOIC-16 package when designing thermal management strategies for high-density layouts.

Part Context

This part belongs to the DG308B/DG309B series, which are improved versions of the industry-standard DG308A and DG309 devices. The DG309 variant specifically provides a normally closed switch configuration, contrasting with the normally open DG308B. Both utilize Vishay's proprietary silicon gate CMOS process for enhanced performance characteristics.
