DZ4J120K0R

Overview

The Panasonic DZ4J120K0R is a surface-mount Zener diode with a nominal voltage of 120V and a power dissipation of 200mW. It utilizes the SMini4 package for compact integration. Key electrical parameters include a maximum reverse leakage current of 50nA, a Zener impedance of 300 ohms, and a maximum operating temperature of +150°C. The component is RoHS compliant and designed for high-reliability applications requiring stable voltage regulation in small form factors.

Feature Summary

• Compact SMini4 surface-mount package design
• High-temperature operation capability up to 150°C
• Low reverse leakage current for precision regulation

Applications

• Voltage reference circuits
• Over-voltage protection
• General-purpose voltage regulation

Procurement Notes

Verify end-of-life status before procurement as availability may be restricted. Confirm package compatibility and thermal requirements against current design specifications. Check for authorized distributors offering remaining stock or qualified replacement components from the same manufacturer series.

Selection Notes

Select this component when a 120V Zener voltage is required in a minimal footprint. Ensure the circuit can handle the 200mW power dissipation at elevated temperatures. Verify that the 300-ohm impedance meets the dynamic regulation needs of the application.

Part Context

This part belongs to the Panasonic DZ4J series of surface-mount Zener diodes. The series is characterized by small packages and high power density relative to size. It serves as a specialized component for modern electronics where space constraints are critical.

Replacement Considerations

Consult official Panasonic documentation for direct cross-reference parts within the DZ4J series. Verify pinout and electrical tolerances if considering alternative manufacturers. No public substitute part numbers are confirmed in available sources.
