Quality Control: Learn More
Microchip Technology JANS1N4491CUS is a high-reliability Zener diode designed for demanding applications. This voltage regulator offers a nominal Zener voltage of 120 V with a tight ±2% tolerance. Engineered to dissipate up to 1.5 W, it features a low reverse leakage current of 250 nA at 96 V and a maximum Zener impedance of 400 Ohms. The JANS1N4491CUS is housed in a SQ-MELF, A (D-5A) surface mount package, suitable for high-density circuit designs. Its military-grade qualification under MIL-PRF-19500/406 ensures performance and reliability across an operating temperature range of -65°C to 175°C. This component is utilized in aerospace, defense, and industrial control systems requiring stable voltage references and transient voltage suppression.
