JANTX1N5526C-1/TR

Single Zener Diodes Overview

The JANTX1N5526C-1/TR is a silicon unidirectional Zener voltage regulator diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.8 V with a tight tolerance of ±2%. The device is rated for a power dissipation of 500 mW and operates within an extended temperature range from -65 °C to +175 °C. Key electrical parameters include a maximum dynamic impedance of 30 Ω at a test current of 1 mA, a maximum reverse leakage current of 1 µA, and a forward voltage of 1.4 V at 1 A. It utilizes the DO-35 (DO-204AH) axial leaded package.
