Overview
The CMPZDA2V7 TR TIN/LEAD is a dual Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 2.7 V and operates within a temperature range of -65 °C to +150 °C. The device is housed in an SOT-323-3 surface-mount package with a power dissipation rating of 275 mW. Key electrical characteristics include a maximum reverse leakage current of 3 µA, a Zener impedance of 10 Ohms, and a test current of 5 mA. The component supports a forward current of 10 mA with a forward voltage of 900 mV.
Feature Summary
- Dual configuration integrating two Zener elements in a single compact package
- Low leakage current specification for sensitive circuit applications
- Wide operating temperature range suitable for harsh environments
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping and protection stages in signal processing paths
- Biasing networks in low-power electronic systems
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status and tape-and-reel packaging details. Ensure compatibility with standard SMT assembly processes for the SOT-323-3 footprint. Cross-reference datasheet parameters with design requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener configuration is required in a minimal footprint. The 2.7 V nominal voltage suits low-voltage reference applications. Verify that the 275 mW power dissipation limit meets thermal constraints in the target enclosure. Confirm that the SOT-323-3 package dimensions align with the PCB layout specifications.
Part Context
This part belongs to the CMPZDA series of dual Zener diodes from Central Semiconductor. The series offers integrated dual-element solutions for space-constrained designs. The CMPZDA2V7 variant specifically provides a 2.7 V breakdown voltage. It complements other voltage options within the same family for flexible circuit design.
Replacement Considerations
Check for direct pin-compatible substitutes with identical 2.7 V dual Zener characteristics. Verify that alternative packages maintain the same electrical ratings and thermal performance. Ensure any replacement matches the SOT-323-3 form factor for seamless integration.
