Overview
The DG3157DL-T1-E3 is a single-channel, single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and is housed in an SC-70-6 surface-mount package. The device features a maximum on-resistance of 15 Ohms and supports a DC switch current of 50 mA. Switching performance includes a maximum turn-on time of 2.6 ns and a maximum turn-off time of 2.6 ns. It functions within a temperature range of -40°C to +85°C with a maximum power dissipation of 250 mW.
Feature Summary
- High-speed CMOS technology enabling rapid signal switching
- Low on-resistance for minimal signal attenuation
- Compact SC-70-6 footprint for space-constrained designs
Applications
- Portable instrumentation signal routing
- Battery-powered measurement systems
- Communication equipment multiplexing
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure the specific tape-and-reel packaging matches production requirements.
Selection Notes
Select this component when low voltage operation below 2.5 V is required alongside fast switching speeds. Compare against the DG9411DL-T1-E3 if higher voltage tolerance is needed, noting its 2.25 V minimum limit. Verify that the 15 Ohm on-resistance meets system impedance requirements compared to lower resistance alternatives.
Part Context
This part belongs to the Vishay DG series of high-speed CMOS analog switches. It shares the SC-70-6 package form factor with other single-channel devices in the lineup, such as the DG9411DL-T1-E3. The series focuses on providing efficient signal path control for portable and battery-operated electronic applications requiring small footprints.
Replacement Considerations
Public records indicate the DG9411DL-T1-E3 as a recommended alternative within the same product family. Verify pin compatibility and electrical parameter differences before substitution.
