DZ23C15HE3-TP

Overview

The DZ23C15HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC) in an SOT-23 surface-mount package. It features a common cathode configuration with two independent diodes housed within a single case. The nominal Zener voltage is 15 V, maintained within a ±5% tolerance band ranging from 14.25 V to 15.75 V at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW and operates across a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum Zener impedance of 30 Ohms and a maximum reverse leakage current of 100 nA at 11 V.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Automotive-grade qualification compliant with AEC-Q101 standards.
• Tight voltage matching between the two internal diodes ensures balanced performance.
• Halogen-free construction utilizing lead-free finishes and UL 94 V-0 rated epoxy.

Applications

• Voltage reference circuits requiring matched dual channels.
• Over-voltage protection stages in automotive electronic control units.
• Clamping applications in industrial signal conditioning systems.
• Power supply regulation modules operating under high thermal stress.

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement channels to mitigate counterfeiting risks. Confirm that the ordering suffix 'TP' corresponds to tape-and-reel packaging containing 3,000 pieces per reel. Ensure compliance with RoHS directives and halogen-free requirements as specified in the official datasheet documentation before finalizing purchase orders.

Selection Notes

Select this component when a dual-channel voltage reference or clamping solution is required in a minimal footprint. The SOT-23 form factor suits automated insertion processes. Verify that the 15 V breakdown voltage aligns with circuit requirements and that the 300 mW power rating accommodates expected thermal loads within the -55°C to +150°C operational envelope.

Part Context

This part belongs to the DZ23C series of dual Zener arrays produced by Micro Commercial Components. The series spans voltage ratings from 2.4 V to 47 V, all sharing the same SOT-23 physical dimensions and common cathode topology. The HE3 designation indicates enhanced environmental compliance, specifically regarding halogen content and lead-free manufacturing processes compared to standard variants.

Replacement Considerations

Direct substitutes must match the 15 V nominal voltage, 300 mW power rating, SOT-23-3 package, and dual common cathode configuration. Verify that alternative components meet AEC-Q101 automotive qualification if used in vehicle applications. Cross-reference Zener impedance and leakage current specifications to ensure circuit compatibility without redesign.
