Microchip Technology JANS1N4494 is a Zener Diode designed for demanding applications requiring precise voltage regulation. This component offers a Zener Voltage (Vz) of 160 V with a tight tolerance of ±5%. Rated for 1.5 W maximum power dissipation, it features a low reverse leakage of 250 nA at 128 V and a maximum Zener impedance (Zzt) of 1000 Ohms. The JANS1N4494 is housed in a DO-41 (DO-204AL, Axial) package, suitable for through-hole mounting. Its operational temperature range spans from -65°C to 175°C (TJ). Qualified to MIL-PRF-19500/406, this device is frequently utilized in aerospace, defense, and high-reliability industrial systems where robust performance and consistent voltage clamping are critical.
