Microchip Technology JANS1N4490 is a 1.5W Zener diode designed for demanding applications. This military-grade component offers a precise 110V Zener voltage with a ±5% tolerance, ensuring stable voltage regulation. Featuring a low reverse leakage current of 250 nA at 88V and a maximum Zener impedance of 300 Ohms, it is suitable for power supply regulation and voltage clamping circuits. The JANS1N4490 is housed in a DO-41 (DO-204AL, Axial) through-hole package, facilitating integration into existing PCB designs. Its wide operating temperature range of -65°C to 175°C (TJ) makes it ideal for use in aerospace, defense, and industrial control systems where reliability under extreme conditions is paramount. The qualification to MIL-PRF-19500/406 underscores its robust performance and adherence to stringent military standards.
