Microchip Technology JANS1N4988CUS-TR is a 5W Zener diode designed for demanding applications. This military-grade component, qualified to MIL-PRF-19500/356, offers a precise 180V Zener voltage with a tight ±2% tolerance. Its 5W power dissipation capability and low reverse leakage of 2 µA at 136.8V make it suitable for voltage regulation and transient suppression in aerospace, defense, and high-reliability industrial systems. The E-MELF package ensures efficient thermal performance and robust surface mounting. With a maximum impedance of 450 Ohms, this device provides stable voltage regulation across a wide operating temperature range of -65°C to 175°C. The forward voltage is a maximum of 1.5V at 1A. The JANS1N4988CUS-TR is supplied in Tape & Reel packaging for automated assembly.
