DZ23C20-TP

Overview

The DZ23C20-TP is a dual common cathode Zener diode manufactured by Micro Commercial Components (MCC). It operates in the SOT-23-3 surface-mount package with dimensions of 3.04 mm length, 1.4 mm width, and 1.12 mm height. The device features a nominal Zener voltage of 20 V with a 5% tolerance at a test current of 5 mA. Maximum power dissipation is rated at 300 mW, while maximum reverse leakage current is limited to 100 nA. The Zener impedance is specified at 55 Ohms. The component supports an operating temperature range from -55°C to +150°C and weighs approximately 8 mg per unit.

Feature Summary

• Dual common cathode configuration for space-efficient circuit design
• Automotive-grade reliability certified under AEC-Q101 standards
• Compact SOT-23-3 surface-mount footprint for automated assembly

Applications

• Voltage reference circuits requiring stable dual-channel regulation
• Clamping and protection stages in automotive electronic control units
• Signal conditioning modules within industrial sensor interfaces

Procurement Notes

Verify the specific datasheet revision and AEC-Q101 qualification status directly with Micro Commercial Components before finalizing procurement. Confirm that the SOT-23-3 package dimensions align with the target PCB land pattern. Ensure compliance with RoHS directives and check for any regional distribution restrictions applicable to this part number.

Selection Notes

Select the DZ23C20-TP when a dual Zener solution is required in a compact form factor for automotive or industrial environments. The 20 V breakdown voltage suits mid-range reference applications. Consider the 55 Ohm impedance for noise-sensitive designs. Verify thermal management requirements against the 300 mW dissipation limit during operation.

Part Context

This component belongs to the DZ23C series of dual Zener diodes from Micro Commercial Components. It shares the SOT-23-3 package and 300 mW power rating with other variants in the family, such as the DZ23C6V2-TP and DZ23C12-TP. The HE3 suffix denotes enhanced efficiency variants, while the standard TP suffix indicates the primary production version.

Replacement Considerations

Cross-reference with other MCC dual Zener diodes in the SOT-23-3 package if pinout compatibility is critical. Verify electrical parameters against alternative manufacturers' parts to ensure equivalent performance in voltage regulation and leakage characteristics.
