DZ4J068K0R

Overview

The DZ4J068K0R is a surface-mount Zener diode manufactured by Panasonic. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 200 mW and operates within a temperature range up to +150 °C. Packaged in the SMini4 F3 B form factor, it measures 2 x 2.1 mm. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 20 ohms.

Feature Summary

• Compact SMini4 F3 B package design suitable for space-constrained surface-mount applications
• High thermal stability supporting operation at elevated temperatures up to +150 °C
• Low leakage current specification ensuring minimal power loss in reverse bias conditions

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Transient voltage suppression in compact electronic assemblies
• Overvoltage protection for sensitive signal lines

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Review official datasheets for updated handling instructions and storage conditions. Ensure compatibility with existing supply chain requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 6.8 V regulation point is required in a small footprint. The 200 mW rating suits low-power signal processing rather than high-current power management. Evaluate the 20-ohm impedance against circuit sensitivity requirements. Consider the SMini4 package dimensions for PCB layout constraints.

Part Context

This part belongs to the Panasonic DZ4J series of surface-mount Zener diodes. These components are designed for general-purpose voltage regulation and protection tasks. The series emphasizes miniaturization while maintaining reliable performance in industrial and consumer electronics environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative manufacturers. Ensure replacement parts match the SMini4 package dimensions and thermal characteristics.
