DZ4J039K0R

Overview

The DZ4J039K0R is a silicon epitaxial planar Zener diode manufactured by Panasonic Electronic Components. It features a dual configuration (DZ2J039 parallel) housed in an SMini4-F3-B package, equivalent to JEITA SC-113BB. The device provides a nominal Zener voltage of 3.9 V with a tolerance range of 3.71 V to 4.10 V at a test current of 5 mA. Total power dissipation is rated at 200 mW, operating within an ambient temperature range of -40 °C to +85 °C and a junction temperature up to 150 °C. Key electrical parameters include a reverse current of 1 µA maximum at 1 V, a Zener impedance of 130 Ω, and a temperature coefficient of -1.3 mV/°C.
