DZ4J360K0R

Overview

The DZ4J360K0R is a silicon epitaxial planar Zener diode manufactured by Panasonic Electronic Components. It provides a nominal Zener voltage of 37.8 V at a test current of 2 mA, with a guaranteed range from 34.20 V to 41.40 V. The device features a low Zener operating resistance of 250 Ω and an excellent rising characteristic for the Zener current. It is housed in a compact SMini4-F3-B package (JEITA SC-113BB) with four terminals configured as two isolated elements. The component supports a total power dissipation of 200 mW and operates within an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Dual-element configuration providing two independent Zener diodes within a single surface-mount package.
• Designed for constant voltage regulation and surge absorption circuit applications.
• Features low Zener operating resistance and excellent rising characteristics in the low-current range.

Applications

• Constant voltage reference circuits
• Surge absorption circuits
• Waveform clipping applications

Procurement Notes

Verify the specific revision status of the datasheet before finalizing procurement, as specifications are subject to change without notice. Confirm that the required packaging format matches the standard embossed reel quantity of 3000 pieces per reel. Ensure compliance with halogen-free and RoHS directives if applicable to your manufacturing environment.

Selection Notes

Select this component when a dual-channel Zener solution is required in a minimal footprint. The SMini4-F3-B package allows for automated assembly processes. Consider the 200 mW power dissipation limit and ensure adequate thermal management on the glass epoxy print board to maintain performance within the specified operating temperature range.

Part Context

This part belongs to the DZ4J series of surface mount Zener diodes from Panasonic. These components utilize a silicon epitaxial planar type construction. The series is designed to offer significantly smaller surface mount packages compared to traditional through-hole alternatives while maintaining high power dissipation capabilities suitable for modern electronic equipment.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching the Zener voltage tolerance, package dimensions, and maximum power dissipation ratings before attempting any cross-referencing.
