AZ23C12WHE3-TP

Overview

The AZ23C12WHE3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components. It features a nominal Zener voltage of 12 V with a tolerance of 5%. The device operates within a power dissipation limit of 300 mW and maintains a maximum reverse leakage current of 100 nA. Electrical testing is conducted at a test current of 5 mA, resulting in a Zener impedance of 20 Ohms. The component exhibits a voltage temperature coefficient of 0.075 %/°C. It supports an operating temperature range from -55 °C to +150 °C. The physical package is SOT-23, measuring 3.04 mm in length, 1.4 mm in width, and 1.12 mm in height.

Feature Summary

• Dual common anode configuration allows for compact circuit design within a single package.
• High-temperature resilience supports operation up to +150 °C for demanding environments.
• Low-profile SMD/SMT packaging facilitates automated assembly processes.

Applications

• Voltage reference circuits requiring stable dual polarity or split rail generation
• Over-voltage protection stages in consumer electronics
• Signal conditioning and clamping in industrial control systems

Procurement Notes

Verify the specific suffix HE3 against official manufacturer documentation to confirm RoHS compliance status and material composition details. Ensure the ordering part number matches the exact electrical specifications required for the target application. Cross-reference datasheet revisions to confirm consistency in thermal characteristics and package dimensions prior to final procurement decisions.

Selection Notes

Select this component when a dual Zener solution is needed in a minimal footprint SOT-23 package. The 12 V rating suits applications requiring precise voltage regulation or clipping near that threshold. Consider the 300 mW power dissipation capability for thermal management planning. Verify that the 5% voltage tolerance meets the system accuracy requirements compared to tighter tolerance alternatives.
