DZ23C56-TP

Overview

The DZ23C56-TP is a dual common cathode Zener diode array manufactured by Micro Commercial Components. It integrates two independent Zener diodes within a single SOT-23-3 surface-mount package. The device features a nominal Zener voltage of 56 V with a 5% tolerance and a maximum power dissipation of 300 mW. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 10 Ohms, and a test current of 5 mA. It operates reliably across an extended temperature range from -55°C to +150°C.

Feature Summary

• Dual common cathode configuration for space-efficient circuit design
• High thermal stability with operation up to +150°C junction temperature
• Low leakage current specification for precision applications
• Compact SOT-23-3 package suitable for automated surface mount assembly

Applications

• Voltage reference circuits requiring dual stable potentials
• Over-voltage protection stages in signal conditioning paths
• Clamping networks for transient suppression in sensitive electronics

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before integration. Confirm that the SOT-23-3 footprint matches the target PCB layout requirements. Ensure supply chain sources are authorized to guarantee component authenticity and traceability for production quality control.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. The 56 V rating suits high-voltage reference or clamping tasks. Verify that the 300 mW power rating accommodates the expected continuous current without exceeding thermal limits. Consider the 10 Ohm impedance if low dynamic resistance is critical for the application performance.

Part Context

This part belongs to the DZ23C series of dual Zener arrays from Micro Commercial Components. It shares the SOT-23-3 form factor with other variants in the family, such as the DZ23C6V2-TP and DZ23C3V6-TP, which offer lower voltage ratings. The series provides a standardized mounting solution for multi-channel voltage regulation needs.

Replacement Considerations

Direct substitutes include other MCC dual Zener arrays in SOT-23-3 packages with matching voltage and power ratings, such as the DZ23C6V2-TP for lower voltage applications. Cross-brand equivalents must match the pinout, package dimensions, and electrical specifications precisely.
