CMPZDA39V TR PBFREE

Overview

The CMPZDA39V TR PBFREE is a dual Zener diode array manufactured by Central Semiconductor Corp. It features two independent Zener diodes integrated into a single surface-mount package, specifically the SOT-23-3 configuration. The nominal Zener voltage for each channel is 39 V, with a power dissipation rating of 500 mW per device. The component operates within a junction temperature range of -65°C to +150°C and supports a maximum reverse leakage current of 10 nA at the test current of 50 µA. This configuration allows for space-efficient circuit design in applications requiring precise voltage referencing or protection.

Feature Summary

• Dual independent Zener channels integrated into a compact SOT-23-3 surface-mount package
• Nominal 39 V regulation voltage with low noise characteristics suitable for sensitive circuits
• High thermal stability supporting operation up to +150°C junction temperature

Applications

• Voltage reference circuits requiring dual stable potentials
• Over-voltage protection for differential signal lines
• Clamping applications in precision analog front-ends

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure the selected variant matches the required electrical parameters for the target application.

Selection Notes

Select this component when dual Zener regulation is required in a minimal footprint. Compare the 39 V nominal voltage and 500 mW power rating against circuit requirements. Consider the SOT-23-3 package constraints for PCB layout. Verify that the leakage current and dynamic impedance specifications meet the precision needs of the design.

Part Context

This part belongs to Central Semiconductor's line of dual Zener diode arrays. These components are designed to replace discrete dual-diode solutions, saving board space and assembly time. The series typically offers matched characteristics between channels, although specific matching data should be verified from the official documentation.

Replacement Considerations

Check for direct pin-compatible alternatives from Central Semiconductor or other manufacturers offering dual Zener arrays in SOT-23-3 packages. Verify that substitute parts match the 39 V nominal voltage, 500 mW power rating, and SOT-23-3 footprint before implementation.
