DZ4J200K0R

Overview

The DZ4J200K0R is a dual Zener diode manufactured by Panasonic Industry, designed for surface-mount applications. It features a nominal Zener voltage of 100 V with a tolerance of ±5%. The device operates within a power dissipation rating of 200 mW and maintains a maximum reverse leakage current of 2 µA at the test current of 5 mA. The component utilizes an SC-113BB package (SMini4) with dimensions of 2 mm x 2.1 mm x 0.7 mm. It supports a wide operating temperature range from -40 °C to +150 °C and exhibits a Zener impedance of 80 Ohms.

Feature Summary

• Dual configuration providing two isolated Zener junctions in a compact footprint
• High thermal stability suitable for elevated temperature environments up to 150 °C
• Low leakage current characteristics ensuring minimal power loss in off-state conditions

Applications

• Voltage reference circuits requiring stable high-voltage regulation
• Over-voltage protection stages in industrial control systems
• Signal conditioning modules in automotive electronics

Procurement Notes

Verify component authenticity through authorized Panasonic distributors or certified suppliers. Confirm RoHS compliance status via official datasheets before integration. Check for end-of-life notifications as discontinuation may affect long-term supply chain stability. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the manufacturing documentation.

Selection Notes

Select this component when dual isolated Zener functionality is required in space-constrained designs. The SMini4 package offers a smaller footprint compared to traditional axial leads while maintaining robust thermal performance. Consider the 100 V breakdown voltage and 200 mW dissipation limits against circuit load requirements. Evaluate the 80 Ohm impedance for noise-sensitive applications where lower dynamic resistance might be necessary.

Part Context

This part belongs to the Panasonic DZ4J series of surface-mount Zener diodes. The series is characterized by its small form factor and high-temperature capability, targeting modern electronic assemblies that demand reliability in harsh environments. It complements other components in Panasonic's discrete semiconductor portfolio for power management and signal integrity solutions.

Replacement Considerations

Direct substitutes include other Panasonic dual Zener diodes in similar packages such as the DZ4J series variants with different voltage ratings. Cross-manufacturer equivalents should match the 2x2.1mm footprint, 200mW power rating, and 100V Zener voltage. Verify pinout compatibility and thermal characteristics before substitution.
