Overview
The DG309DY-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Semiconductors. It operates within a supply voltage range of 13 V to 36 V for single supplies, or ±15 V for dual supplies. The device features a maximum on-resistance of 100 Ohms and supports a continuous DC switch current of 20 mA. Electrical performance includes a maximum turn-on time of 200 ns and a maximum turn-off time of 150 ns. Power dissipation is rated at 600 mW. The component functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates four independent SPST analog switches in a compact surface-mount package
- Supports both single and dual power supply configurations for flexible system design
- Provides high isolation characteristics with low leakage current specifications
Applications
- Signal routing in data acquisition systems
- Multiplexing applications for sensor interfaces
- Programmable gain amplifier circuits
Procurement Notes
Verify the specific ordering suffix to confirm the package type and lead-free status. Confirm that the requested quantity matches the standard tube packaging format. Check for any recent product discontinuation notifications as this part may have limited availability. Ensure the supplier provides valid RoHS compliance documentation upon request.
Selection Notes
Select this component when a quad SPST configuration is required for moderate-speed signal switching. Verify that the 100 Ohm on-resistance meets the application's signal integrity requirements. Ensure the operating voltage stays within the specified 13 V to 36 V single-supply range. Consider thermal management if multiple channels are active simultaneously due to the 600 mW power dissipation limit.
Part Context
This device belongs to the DG series of CMOS analog switches produced by Vishay Siliconix. It serves as a surface-mount alternative to through-hole variants like the DG309CJ-E3. The component is designed for general-purpose analog signal switching tasks requiring reliable performance in industrial and commercial environments.
