CMPZDA43V TR PBFREE

Overview

The CMPZDA43V TR PBFREE is a dual Zener diode manufactured by Central Semiconductor Corp. It features a common cathode configuration housed in an SOT-23 package. The nominal Zener voltage is 43 V with a maximum power dissipation of 500 mW. The device supports a continuous forward current of 250 mA and operates within a temperature range of -65°C to +175°C. Reverse leakage current is specified at 5 µA at 32.7 V, with a maximum impedance of 70 Ohms.

Feature Summary

• Dual Zener diode structure with common cathode configuration
• High thermal stability supporting operation up to 175°C
• Compact surface-mount SOT-23 packaging for space-constrained designs

Applications

• Voltage reference circuits requiring dual regulated rails
• Clamping and protection in low-power signal lines
• Biasing networks in analog integrated circuits

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout orientation and electrical tolerances. Ensure the ordering code matches the required tape-and-reel quantity specifications. Cross-reference the RoHS compliance status with the latest environmental declaration provided by Central Semiconductor before finalizing procurement.

Selection Notes

Select this component when a dual Zener solution is preferred over discrete single units to save board space. Verify that the 43 V breakdown voltage aligns with the target circuit requirements. Confirm that the SOT-23 package thermal characteristics are sufficient for the expected power dissipation in the application environment.
