DZ4J030K0R

Overview

The DZ4J030K0R is a dual silicon epitaxial planar Zener diode manufactured by Panasonic. It features two parallel Zener elements within an SMini4-F3-B package, measuring 2.1 mm in length, 2.0 mm in width, and 0.7 mm in height. The device provides a nominal Zener voltage of 30 V with a tolerance of ±5% at a test current of 5 mA. Total power dissipation is rated at 200 mW, with an operating ambient temperature range from -40 °C to +85 °C. Key electrical parameters include a maximum reverse leakage current of 1 µA at 1 V, a Zener impedance of 120 Ω, and a forward voltage of 1.0 V at 10 mA.

Feature Summary

• Dual configuration providing two independent Zener channels in a compact surface-mount footprint.
• Low Zener operating resistance (Rz) for stable voltage regulation performance.
• Excellent rising characteristics of Zener current (Iz) for fast response applications.
• Halogen-free and RoHS compliant construction suitable for environmentally regulated manufacturing.

Applications

• Constant voltage reference circuits requiring dual channels.
• Surge absorption circuits for transient voltage suppression.
• Waveform clipping applications in signal processing.

Procurement Notes

Verify the specific ordering suffix K0R against official Panasonic documentation to confirm packaging details and compliance status. Confirm availability through authorized distributors as standard lead times may vary. Ensure design-in reviews account for the absolute maximum ratings regarding junction temperature and thermal dissipation constraints during procurement planning.

Selection Notes

Select this component when a dual-channel Zener solution is required in a minimal footprint. The SMini4-F3-B package supports high-density PCB layouts. Verify that the 30 V breakdown voltage aligns with circuit requirements and that the 200 mW power rating accommodates the expected thermal load on the designated glass epoxy print board.
