VOLTAGE REGULATORManufacturer: Microchip Technology
Categories: Single Zener Diodes
Quality Control: Learn More
Microchip Technology JANS1N4493CUS-TR is a high-reliability, surface-mount Zener diode rated for 150V nominal breakdown voltage and 1.5W maximum power dissipation. This military-grade component, qualified to MIL-PRF-19500/406, features a tight ±2% tolerance for precise voltage regulation. Its SQ-MELF, A (D-5A) package is suitable for demanding applications. The diode exhibits a low reverse leakage of 250 nA at 120V and a maximum Zener impedance (Zzt) of 700 Ohms at its rated voltage. Operating across a wide temperature range of -65°C to 175°C, it is utilized in aerospace, defense, and industrial power supply circuits where robust and stable voltage reference is critical. The JANS1N4493CUS-TR is supplied in tape and reel packaging for automated assembly.
