DZ4J082K0R

Overview

The Panasonic DZ4J082K0R is a dual silicon epitaxial planar Zener diode in an SMini4-F3-B package. It provides two isolated Zener elements with a nominal voltage of 8.2V at a test current of 5mA and a tolerance of ±5%. The device supports a total power dissipation of 200mW, operating within a temperature range of -40°C to +150°C. Key electrical parameters include a maximum reverse leakage current of 60nA, a Zener impedance of 20Ω, and a typical temperature coefficient of 4.7mV/°C. It features excellent ESD protection rated at ±8kV.

Feature Summary

• Dual configuration providing two independent Zener channels for constant voltage regulation or surge absorption.
• Low Zener operating resistance (Rz) combined with excellent rising characteristics of Zener current (Iz).
• High electrostatic discharge (ESD) immunity rated at ±8kV for robust circuit protection.
• Halogen-free and RoHS compliant construction suitable for general electronic equipment.

Applications

• Constant voltage reference circuits in office equipment and measuring instruments.
• Surge absorption circuits for communications equipment.
• Voltage clamping applications in household appliances.

Procurement Notes

Verify the specific ordering suffix against official Panasonic documentation to confirm packaging details and compliance status. Ensure that the procurement channel sources genuine components directly from authorized distributors to avoid counterfeit parts. Confirm that the delivered units match the exact part number DZ4J082K0R before integration into production lines.

Selection Notes

Select this component when a dual-channel Zener solution is required in a compact surface-mount footprint. The 200mW power rating and wide operating temperature range support diverse industrial environments. Verify that the 8.2V breakdown voltage aligns with the target circuit requirements and that the low impedance characteristics meet the signal integrity needs.

Part Context

This component belongs to the Panasonic DZ4J series of surface mount Zener diodes. The series is designed to offer significantly smaller packages compared to previous generations while maintaining high power dissipation capabilities. The DZ4J082K0R specifically utilizes the SMini4-F3-B package format, which corresponds to the JEITA SC-113BB standard.
