Overview
The DG309BDJ-E3 is a quad single-pole single-throw (SPST) analog switch from the DG309B series, manufactured by Vishay Siliconix. It features a 16-pin Plastic DIP package and operates within an extended temperature range of -40 °C to +85 °C. The device supports dual supply voltages up to ±22 V or single supplies up to 44 V. Key electrical parameters include a maximum on-resistance of 100 Ω at full temperature range, turn-on time of 200 ns, and turn-off time of 150 ns. Supply current is typically 1 µA, with off-leakage currents in the nanoampere range.
Feature Summary
- CMOS fabrication process for low power consumption and high speed
- Extended analog signal handling capability up to ±22 V
- Improved charge injection compensation design minimizes switching transients
- Epitaxial layer integration prevents latchup issues
Applications
- Industrial instrumentation systems
- Test equipment signal routing
- Sample-and-hold circuits
- Communications systems
- Computer peripherals
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the specific ordering suffix '-E3'. Validate package integrity upon receipt, as the 16-pin DIP form factor requires appropriate handling during assembly. Cross-reference datasheet revision G specifications against procurement documentation to ensure parameter consistency.
Selection Notes
Select this part when a normally closed SPST configuration is required for analog signal paths. The 16-pin DIP package suits through-hole prototyping or legacy board designs. Ensure supply voltage limits do not exceed ±22 V for continuous operation. Consider thermal derating requirements if operating near the upper temperature limit of +85 °C.
Part Context
This component belongs to the DG309B family, representing an improved version of the industry-standard DG309. It offers lower on-resistance and leakage compared to predecessors like the DG308A/DG309. The 'DJ' suffix denotes the 16-pin Plastic DIP package, while '-E3' indicates lead-free termination compliant with RoHS directives.
Replacement Considerations
DG309BDJ: Non-RoHS compliant variant with identical electrical characteristics. DG309BDY-E3: Surface-mount SOIC-16 equivalent. DG309BDQ-E3: Compact TSSOP-16 alternative. Verify pinout compatibility and thermal dissipation differences when substituting packages.
