Microchip Technology JANS1N4490DUS is a high-reliability Zener diode designed for demanding applications. This military-grade component offers a precise 110V nominal Zener voltage with a tight ±1% tolerance. Rated for 1.5W power dissipation, it features a low reverse leakage of 250 nA at 88V and a maximum Zener impedance of 300 Ohms. The JANS1N4490DUS is housed in a compact SQ-MELF, A (D-5A) surface-mount package suitable for automated assembly. Its robust construction and qualification under MIL-PRF-19500/406 ensure performance in harsh environments, making it ideal for aerospace, defense, and industrial control systems where stable voltage regulation is critical. The operating temperature range is -65°C to 175°C.
