Microchip Technology JANTX1N4990DUS-TR is a Zener Diode designed for high-reliability applications. This military-grade component, qualified to MIL-PRF-19500/356, features a ±1% voltage tolerance, providing precise 220 V Zener regulation. With a robust 5 W power dissipation and a low 2 µA reverse leakage at 167 V, it is suitable for demanding voltage regulation and transient suppression tasks. The low impedance characteristic of 550 Ohms (Max) at Zzt further enhances its performance in critical circuits.
The E-MELF (SQ-MELF, E) package facilitates efficient surface mounting, ideal for compact and high-density board designs. Operating across a wide temperature range of -65°C to 175°C (TJ), this device is well-suited for aerospace, defense, and industrial control systems where extreme environmental conditions are prevalent. The forward voltage drop is a maximum of 1.5 V at 1 A. Packaged in Tape & Reel (TR) for automated assembly.
