Microchip Technology JAN1N4991US-TR is a 5 W Zener diode offering a nominal Zener voltage of 240 V with a ±5% tolerance. This military-grade component, qualified under MIL-PRF-19500/356, features a low reverse leakage of 2 µA at 182 V and a maximum Zener impedance (Zzt) of 650 Ohms. Designed for robust performance, it operates across a wide temperature range of -65°C to 175°C. The device is housed in an E-MELF (SQ-MELF, E) package suitable for surface mounting and supplied on tape and reel (TR). Typical applications include voltage regulation and surge suppression in aerospace, defense, and demanding industrial systems. The forward voltage (Vf) is 1.5 V at 1 A.
