DZ23C36-TP

Overview

The DZ23C36-TP is a dual common cathode Zener diode array manufactured by Micro Commercial Components. It features a nominal Zener voltage of 36 V with a maximum power dissipation of 300 mW. The device is housed in an SOT-23-3 surface-mount package and operates within a temperature range of -55°C to +150°C junction temperature. Key electrical parameters include a maximum reverse leakage current of 100 nA at 25.2 V, a Zener impedance of 90 Ohms, and a test current of 2 mA. The component complies with RoHS standards and is supplied in reel, cut tape, or MouseReel packaging formats.

Feature Summary

• Dual common cathode configuration for space-efficient circuit design
• Surface-mount SOT-23-3 package suitable for automated assembly
• Automotive-grade AEC-Q101 qualification for reliability
• Wide operating temperature range from -55°C to +150°C

Applications

• Voltage reference circuits requiring dual independent references
• Clamping and protection stages in automotive electronics
• Signal conditioning modules in industrial control systems
• Power supply regulation and monitoring interfaces

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as distribution channels may list multiple packaging options such as reel or cut tape. Confirm AEC-Q101 compliance requirements if the application mandates automotive grade standards. Cross-reference the manufacturer part number with official datasheets to ensure compatibility with existing bill of materials and avoid substitution errors during procurement.

Selection Notes

Select this component when a dual Zener array with common cathode topology is required in a compact SOT-23 footprint. Ensure the 36 V breakdown voltage aligns with the target circuit reference levels. Verify that the 300 mW power rating suffices for the expected thermal environment. Consider the 90 Ohm impedance value for high-frequency noise performance requirements in sensitive signal paths.

Part Context

This part belongs to the DZ23C36 series of dual Zener arrays from Micro Commercial Components. It shares the same core electrical specifications as the AZ23C36HE3-TP but differs in internal configuration, offering a common cathode arrangement instead of common anode. Both devices utilize the SOT-23-3 package and target similar voltage regulation applications within the same thermal and power constraints.

Replacement Considerations

The AZ23C36HE3-TP serves as a functional substitute within the same product family. Designers must account for the difference between common cathode (DZ23C36-TP) and common anode (AZ23C36HE3-TP) configurations, which necessitates schematic polarity adjustments. Other series members like AZ23C36W-TP offer lower power ratings and should be evaluated for thermal adequacy.
