DZ23C16HE3-TP

Overview

The DZ23C16HE3-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 integrated diodes sharing a single case. The nominal Zener voltage is 16 V, with a tolerance range of 15.20 V to 16.80 V at a test current of 5.0 mA. Maximum Zener impedance is specified at 40 Ohms, and maximum reverse leakage current is 0.1 µA at 12.0 V. The device supports a power dissipation of 300 mW, operates within a junction temperature range of -55°C to +150°C, and holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-constrained designs.
• Tight voltage matching between the two internal diodes ensures consistent performance.
• Automotive-grade qualification ensures reliability under demanding environmental conditions.
• Halogen-free construction meets green manufacturing standards.

Applications

• Voltage reference circuits requiring matched dual channels.
• Automotive electronic control units and instrument clusters.
• Over-voltage protection for sensitive signal lines.
• Clamping applications in industrial sensor interfaces.

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement from Micro Commercial Components Corp. to avoid counterfeit components. Confirm the specific suffix matches the required packaging format. Ensure compliance with RoHS directives and UL 94 V-0 flammability ratings as stated in the official datasheet documentation.

Selection Notes

Select this component when a matched pair of Zener diodes is required in a minimal footprint. The common cathode arrangement simplifies circuit topology compared to discrete solutions. Verify that the 16 V breakdown voltage aligns with the target regulation requirements and that the 300 mW power rating accommodates the expected thermal load in the final assembly.

Part Context

This part belongs to the DZ23C series of dual Zener arrays covering voltages from 2.4 V to 47 V. All variants share identical physical dimensions and electrical characteristics except for the specific Zener voltage values. The series is designed for automated insertion and offers high consistency across the product line.

Replacement Considerations

Direct substitutes include other DZ23C series parts with different voltage ratings if the circuit allows. Cross-brand equivalents must be verified against the SOT-23 pinout and electrical limits. No alternative part numbers are explicitly confirmed as functional replacements in the provided source material.
