DZ4J240K0R

Overview

The Panasonic DZ4J240K0R is a dual isolated Zener diode configured for surface-mount installation within the SMini4 F3 B package. It features four pins and operates with a nominal Zener voltage of 24V and a maximum power dissipation of 200 mW. The device maintains a tight voltage tolerance of 5% at a test current of 5 mA, ensuring stable regulation characteristics. Key electrical parameters include a maximum Zener impedance of 1 kΩ and a maximum reverse leakage current of 10 nA. Designed for high-temperature environments, it supports an operating temperature range up to +150 °C, making it suitable for demanding electronic applications requiring compact dual-channel voltage reference solutions.

Feature Summary

• Dual isolated configuration providing two independent Zener channels in a single compact footprint
• High thermal stability supporting operation at temperatures up to +150 °C
• Low leakage current characteristics enhancing precision in sensitive signal paths

Applications

• Voltage reference circuits requiring dual isolated channels
• Over-voltage protection stages in compact consumer electronics
• Signal conditioning modules in automotive control units

Procurement Notes

Verify the specific suffix K0R against official Panasonic documentation to confirm exact tolerance and packaging specifications. Cross-reference the SMini4 F3 B package dimensions with your PCB layout tools to ensure mechanical compatibility. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener solution is required in a minimal surface-mount area. Ensure the circuit design accounts for the 200 mW power dissipation limit at elevated ambient temperatures. Verify that the 1 kΩ impedance meets the dynamic regulation requirements of the target application compared to lower impedance alternatives.

Part Context

This part belongs to the Panasonic DZ4J series of surface-mount Zener diodes. The series is characterized by its small SMini4 package and high-temperature capability. It serves as a specialized component for designs needing multiple voltage references or protection channels within restricted board space constraints typical of modern miniaturized electronics.
