Microsemi Corporation JANTX1N4491DUS is a Zener diode designed for demanding applications. This device offers a nominal Zener voltage of 120V with a ±5% tolerance, ensuring precise voltage regulation. Rated for 1.5W maximum power dissipation, it features a low reverse leakage current of 250 nA at 96V and a maximum Zener impedance of 400 Ohms.
The JANTX1N4491DUS is packaged in a D-5A (SQ-MELF, A) surface mount case, suitable for high-density board designs. Operating across a wide temperature range of -65°C to 175°C, this component meets the stringent requirements of military-grade specifications, specifically MIL-PRF-19500/406 qualification. It is commonly employed in aerospace, defense, and high-reliability industrial systems where robust voltage stabilization is critical. The forward voltage drop at 200mA is a maximum of 1V.
