VOLTAGE REGULATORManufacturer: Microchip Technology
Categories: Single Zener Diodes
Quality Control: Learn More
Microchip Technology's 1N4490US-TR is a 1.5W Zener diode designed for voltage regulation applications. This surface-mount device, housed in a D-5A (SQ-MELF, A) package, offers a nominal Zener voltage of 110V with a ±5% tolerance. It exhibits a maximum reverse leakage of 250 nA at 88V and a Zener impedance (Zzt) of 300 Ohms. The diode is rated for a maximum power dissipation of 1.5W and operates within an extended temperature range of -65°C to 175°C (TJ). Its robust construction and precise regulation make it suitable for use in industrial control systems, power supplies, and general-purpose clamping circuits. The component is supplied in a Digi-Reel® for automated assembly processes.
