DZ23C22HE3-TP

Overview

The DZ23C22HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC) in an SOT-23 package. It features a common cathode configuration with two independent Zener diodes sharing a single ground terminal. The nominal Zener voltage is 22 V, with a tolerance of ±5% and a maximum test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the device operates within a junction temperature range of -55°C to +150°C. It holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Dual Zener diodes integrated into a single compact surface-mount package
• Common cathode configuration simplifies circuit layout
• AEC-Q101 qualified for automotive reliability standards
• Halogen-free "Green" device compliant with environmental regulations

Applications

• Automotive electronic circuits requiring voltage regulation
• Overvoltage protection for sensitive signal lines
• Voltage reference generation in low-power systems

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement channels. Counterfeit components pose significant risks; ensure traceability and compliance with MCC quality standards. Confirm RoHS compliance and packaging specifications match project requirements before finalizing orders.

Selection Notes

Select this component when a dual-channel voltage reference or protection scheme is needed in a space-constrained design. Ensure the required Zener voltage aligns with the 22 V nominal specification and that the 300 mW power rating accommodates the expected operating conditions.

Part Context

This part belongs to the DZ23C series from MCC, covering Zener voltages from 2.4 V to 47 V. All variants share the same SOT-23 footprint and electrical characteristics structure, differing only in their specific breakdown voltage ratings. This allows for standardized PCB layouts across different voltage requirements.

Replacement Considerations

Direct substitutes include Vishay's DZ23C22-G3-18 and Diodes Incorporated's DZ23C22-7, which offer identical 22 V dual Zener functionality in the SOT-23-3 package. Verify pinout compatibility and thermal resistance values when cross-referencing datasheets.
