Microchip Technology JAN1N4990US-TR is a high-reliability 5W Zener diode designed for demanding applications. This military-grade component, qualified to MIL-PRF-19500/356, features a precise 220V nominal Zener voltage with a ±5% tolerance. It offers a low reverse leakage of 2 µA at 167V and a maximum impedance of 550 Ohms. The JAN1N4990US-TR is packaged in an E-MELF (SQ-MELF, E) for surface mounting and is supplied on tape and reel for automated assembly. Its robust design and wide operating temperature range of -65°C to 175°C make it suitable for use in aerospace, defense, and industrial power supply circuits requiring stable voltage regulation. The forward voltage is specified at a maximum of 1.5V at 1A.
