Overview
The DZ23C22-HE3-08 is a dual common cathode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It is housed in an SOT-23-3 surface-mount package with a total power dissipation of 300 mW. The nominal Zener voltage is 22 V with a tolerance of ±5%. Key electrical parameters include a maximum reverse leakage current of 100 nA and a Zener impedance of 40 Ohms. The device operates within a temperature range of -55°C to +150°C and features a voltage temperature coefficient of 1 mV/°C.
Feature Summary
- Dual common cathode configuration for space-efficient circuit design
- Automotive grade qualification ensuring reliability in harsh environments
- Low leakage current characteristics for sensitive signal applications
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection in automotive electronic modules
- Clamping applications in data line protection schemes
Procurement Notes
Verify the specific ordering suffix and manufacturer lot codes against the latest Vishay datasheet before procurement. Confirm RoHS compliance status and AEC-Q101 qualification requirements for your specific application environment. Ensure the SOT-23-3 footprint matches your PCB layout constraints and thermal management plan.
Selection Notes
Select this component when a dual Zener configuration is required in a compact SOT-23-3 package. Compare the 300 mW power rating and 22 V breakdown voltage against system requirements. Consider the 40 Ohm impedance and low leakage current for precision applications. Verify that the operating temperature range meets the environmental conditions of the target assembly.
Part Context
This part belongs to the DZ23 series of Zener diode arrays from Vishay. It shares the SOT-23-3 form factor with other variants in the family, such as the AZ23 series. The HE3 suffix indicates a specific lead-free and halogen-free compliant version within the Vishay discrete semiconductor portfolio.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Vishay technical support or authorized distributors for verified cross-reference options compatible with the DZ23C22-HE3-08 specifications.
