DG201BDQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BDQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates with dual supplies ranging from ±4.5 V to ±22 V or a single supply up to 25 V. The device features a maximum on-resistance of 85 Ω at room temperature and 100 Ω across the full operating range. Switching times are specified with a maximum turn-on time of 300 ns and a maximum turn-off time of 200 ns. It supports continuous current ratings of 30 mA and includes an epitaxial layer to prevent latchup.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation, as ordering suffixes may affect environmental declarations. Cross-reference the exact part number against current Vishay datasheets to ensure functional equivalence before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed signal paths within the DG201B family. Ensure the system voltage does not exceed the ±22 V dual supply limit. Verify that the required switching speed meets the 300 ns turn-on specification. Consider thermal derating requirements if power dissipation exceeds package limits in high-temperature environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201B series, representing an improved version of the industry-standard DG201A. It offers lower on-resistance, reduced leakage, and faster switching speeds compared to previous iterations. The TSSOP-16 package provides space savings suitable for dense printed circuit board layouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG201BDQ-E3 serves as a direct lead-free alternative without the tape-and-reel packaging. DG201BDY-T1-E3 offers identical electrical characteristics but utilizes a narrow SOIC-16 package instead of TSSOP.
