Overview
The CMPZDA47V TR TIN/LEAD is a dual silicon Zener diode manufactured by Central Semiconductor Corp, housed in an SOT-323-3 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 4.7 V and a maximum power dissipation of 250 mW. The device operates within a temperature range of -65°C to +150°C and exhibits a maximum reverse leakage current of 3 µA at the specified test conditions.
Feature Summary
- Dual Zener diodes integrated into a single compact surface-mount package for space-constrained designs.
- Common cathode configuration simplifies circuit layout and reduces component count.
- High thermal stability supports reliable operation across extended industrial temperature ranges.
Applications
- Voltage reference circuits requiring precise dual rail generation.
- Over-voltage protection stages in sensitive signal paths.
- Clamping applications in communication equipment interfaces.
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with standard SMT reflow profiles and confirm that the requested quantity aligns with the manufacturer's minimum order requirements for reel-based distribution.
Selection Notes
Select this component when a dual Zener solution is required in a minimal footprint. Compare the 4.7 V breakdown voltage against circuit tolerance requirements. Evaluate the 250 mW power rating against expected peak currents to ensure adequate thermal headroom during continuous operation.
Part Context
This part belongs to the CMPZDA series of dual Zener diodes from Central Semiconductor. The series offers various voltage options in the SOT-323-3 package, providing designers with standardized dual-diode solutions for voltage regulation and protection tasks without increasing board area.
Replacement Considerations
Consult official cross-reference guides for equivalent dual Zener diodes in SOT-323 packages. Verify pinout compatibility and electrical parameter alignment before substitution.
