VOLTAGE REGULATORManufacturer: Microchip Technology
Categories: Single Zener Diodes
Quality Control: Learn More
Microchip Technology JAN1N4991CUS-TR is a Zener diode designed for high-reliability applications, featuring a nominal Zener voltage of 240 V with a tight ±2% tolerance. This 5 W device is housed in an E-MELF (SQ-MELF, E) surface mount package, suitable for demanding environments. With a low reverse leakage of 2 µA at 182 V and a maximum Zzt impedance of 650 Ohms, it offers precise voltage regulation. The JAN1N4991CUS-TR operates across a wide temperature range of -65°C to 175°C (TJ) and meets the stringent requirements of MIL-PRF-19500/356 qualification, indicating its use in defense and aerospace industries. The forward voltage at 1 A is rated at a maximum of 1.5 V. This component is supplied in Tape & Reel packaging.
