Microchip Technology JANS1N4479 is a military-grade Zener diode designed for demanding applications. This axial-leaded device features a nominal Zener voltage of 39 V with a tight tolerance of ±5%. Rated for 1.5 W maximum power dissipation, it exhibits a typical impedance of 30 Ohms at its Zener test current. The JANS1N4479 operates across a wide temperature range of -65°C to 175°C (TJ) and is packaged in a DO-41 (DO-204AL) case for through-hole mounting. Its low reverse leakage current is specified at 50 nA at 31.2 V. This component is qualified to MIL-PRF-19500/406, making it suitable for use in aerospace, defense, and other high-reliability electronic systems.
