CMPZDA3V0 TR PBFREE

Overview

The CMPZDA3V0 TR PBFREE is a dual, common anode silicon Zener diode manufactured by Central Semiconductor Corp. It operates within a surface-mount SOT-23 package and provides a nominal Zener voltage of 3.0 V with a test current of 5.0 mA. The device supports a maximum power dissipation of 350 mW at 25°C ambient temperature. Electrical specifications include a maximum Zener impedance (ZZT) of 95 Ω at the test current and a reverse leakage current of 10 μA at 1.0 V. The component functions reliably across a junction temperature range from -65°C to +175°C.

Feature Summary

• Dual configuration with a shared common anode terminal for space-efficient circuit design
• High thermal stability supporting operation up to 175°C junction temperature
• Low forward voltage drop characteristic of 0.9 V maximum at 10 mA forward current

Applications

• Industrial voltage regulation circuits
• Commercial power supply protection
• Computer system logic level clamping
• Entertainment equipment signal conditioning

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm plating composition. The PBFREE designation indicates lead-free compliant terminals per standard industry definitions. Confirm the reel quantity matches automated assembly requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener topology with a common anode is required in a compact SOT-23 footprint. Ensure the 350 mW total power dissipation rating accommodates the combined thermal load of both diodes in the application environment. Verify that the 95 Ω impedance specification meets the noise and regulation requirements of the target circuit.

Part Context

This part belongs to the CMPZDA series, which covers a wide voltage range from 2.4 V to 47 V. All devices in this family share identical physical packaging and pinout configurations while varying only in their specific Zener voltage breakdown characteristics and associated impedance values.

Replacement Considerations

Direct replacements must match the SOT-23-3 package and dual common anode configuration. Verify that substitute components offer equivalent or superior power dissipation ratings and compatible operating temperature ranges to ensure mechanical and electrical interchangeability.
