Overview
The DZ23C30HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC). It features two unidirectional voltage regulator diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 30 V with a tolerance of ±5%, ranging from 28.5 V to 31.5 V at a test current of 5.0 mA. Maximum power dissipation is 300 mW, and the maximum Zener impedance is 80 Ω. The device operates within a junction temperature range of -55°C to +150°C and is AEC-Q101 qualified.
Feature Summary
- Dual Zener diodes integrated in a single common cathode package for space-efficient designs.
- Tight voltage matching between both diodes ensures consistent performance within one case.
- AEC-Q101 qualification supports automotive electronics applications.
- Halogen-free construction meets environmental standards.
Applications
- Automotive circuit protection
- Voltage reference generation
- Surge suppression
Procurement Notes
Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm RoHS compliance and packaging specifications match project requirements. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines before soldering.
Selection Notes
Select this component when dual independent voltage regulation is required in a compact surface-mount footprint. Verify that the 30 V nominal breakdown voltage aligns with circuit design needs. Consider the 80 Ω impedance limit for dynamic load variations.
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 thermal characteristics, differing only in electrical breakdown parameters.
Replacement Considerations
Direct substitutes include other DZ23C30HE3-TP units from MCC. Cross-brand replacements require matching SOT-23-3 pinout, 300 mW power rating, and dual common cathode configuration.
