AZ23C15WHE3-TP

Overview

The AZ23C15WHE3-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It belongs to the AZ23 series and is housed in an SOT-323 surface-mount package. The device features a dual common-anode configuration, integrating two Zener diodes within a single compact footprint. This design facilitates automated assembly processes while maintaining precise voltage matching between the internal components. The unit is RoHS compliant and utilizes halogen-free materials.

Feature Summary

• Dual common-anode Zener array configuration for space-saving integration
• Tight voltage tolerance with delta V-Z less than or equal to 5 percent between matched pairs
• Compatible with automated surface-mount assembly processes
• Halogen-free construction with UL 94 V-0 rated epoxy resin

Applications

• Voltage reference circuits requiring matched dual channels
• Clamping applications in portable electronic devices
• Signal conditioning in compact consumer electronics
• Power management modules in space-constrained PCB designs

Procurement Notes

Verify the specific datasheet version before procurement, as MCC may update component specifications without changing the base part number. Confirm that the SOT-323 package dimensions align with your PCB footprint requirements. Ensure supply chain sources provide genuine MCC products to avoid counterfeit risks associated with small signal diodes.

Selection Notes

Select this component when a dual Zener solution is required in an SOT-323 package. The common-anode topology suits applications needing simultaneous clamping or reference functions. Compare leakage current specifications at operating temperatures against similar Vishay or Diodes Inc alternatives if thermal performance is critical.

Part Context

This part is part of the broader AZ23C family from Micro Commercial Components, which includes various voltage ratings such as 10V, 22V, and 36V variants. The HE3 suffix typically indicates a specific manufacturing lot or compliance marking consistent with MCC's RoHS standards. It serves as a direct replacement for legacy dual Zener designs previously implemented using discrete components.

Replacement Considerations

AZ23C15-E3-08 by Vishay General Semiconductor offers a comparable dual Zener specification in a similar small outline package. Verify pinout compatibility and thermal resistance differences before substituting in existing designs.
