AZ23B12HE3-TP

Overview

The AZ23B12HE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 12 V with a 5% tolerance and a maximum reverse leakage current of 100 nA. The device operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 300 mW. Packaged in an SOT-23 surface-mount case, it is designed for compact circuit applications requiring precise voltage regulation.

Feature Summary

• High thermal stability across extended operating temperatures
• Low leakage current characteristics

Applications

• Voltage reference circuits
• Signal clipping and protection
• Portable electronic devices

Procurement Notes

Verify the specific datasheet version for the AZ23B12HE3-TP to confirm electrical parameters and mechanical dimensions. Ensure compatibility with SOT-23 footprint requirements during PCB layout. Cross-reference manufacturer documentation for RoHS compliance status and handling precautions.

Selection Notes

Select this component when a dual Zener solution in a small outline package is required. Consider the 300 mW power dissipation limit and 12 V nominal voltage for appropriate biasing conditions. Verify that the SOT-23 package size fits the available board space constraints.

Part Context

This part belongs to the AZ23B series of dual Zener diodes from MCC. It shares the SOT-23 package form factor with other variants in the family but differs in Zener voltage ratings. The HE3 suffix typically indicates Halogen-free and Green compliant manufacturing processes.

Replacement Considerations

Check for direct equivalents such as the AZ23C12-TP or similar dual Zener diodes in SOT-23 packages from other manufacturers. Ensure voltage tolerance and power dissipation ratings match the original design requirements before substitution.
