DZ4J091K0R

Overview

The Panasonic DZ4J091K0R is a dual silicon epitaxial planar Zener diode in an SMini4-F3-B package. It provides two isolated Zener channels with a nominal voltage of 8.65 V at a test current of 5 mA and a tolerance of ±5%. The device supports a total power dissipation of 200 mW, operates within a junction temperature range of -40 °C to +150 °C, and features a maximum reverse leakage current of 1.0 µA at 6 V. Key electrical parameters include a Zener impedance of 60 Ω max, a temperature coefficient of 5.8 mV/°C, and ESD protection rated at ±8 kV.

Feature Summary

• Dual-channel configuration providing two independent Zener diodes in a compact surface-mount footprint.
