AZ23C6V8HE3-TP

Overview

The AZ23C6V8HE3-TP is a dual common anode Zener diode array manufactured by Micro Commercial Components. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5.88% at a test current of 5 mA. The device operates in a surface-mount SOT-23-3 package and dissipates up to 300 mW. Key electrical parameters include a maximum reverse leakage current of 2 µA at 4 V, a Zener impedance of 15 Ohms, and a voltage temperature coefficient of 4.5 mV/°C. It is qualified to AEC-Q101 standards for automotive applications and functions within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual common anode configuration integrates two Zener diodes into a single compact footprint.
• Automotive-grade qualification ensures reliability under rigorous environmental conditions.
• Low-profile SOT-23-3 package facilitates automated placement on high-density circuit boards.

Applications

• Voltage reference circuits requiring stable dual rails.
• Transient voltage suppression in automotive electronic control units.
• Clamping protection for sensitive input/output lines in industrial systems.

Procurement Notes

Verify the specific suffix HE3-TP against the target bill of materials to confirm halogen-free compliance and packaging format. Confirm that the AEC-Q101 automotive grade requirement aligns with the design specifications. Check for any recent product change notices regarding reel updates or labeling changes before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution is required in a minimal surface-mount area. The 6.8 V rating suits mid-range reference applications. Ensure the 300 mW power dissipation capability meets the thermal requirements of the host PCB layout. Verify that the 15 Ohm impedance is acceptable for the intended signal integrity constraints.

Part Context

This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. It shares the SOT-23-3 form factor with other variants in the family but differs in voltage ratings and specific electrical tolerances. The HE3 designation indicates a halogen-free compliant version of the standard AZ23C6V8-TP.

Replacement Considerations

The AZ23C6V8-TP is a non-halogenated variant within the same series. Verify if halogen-free certification is mandatory for the application. Other voltage variants in the AZ23C series share the package but require re-evaluation of circuit biasing and clamping levels.
