MICROCHIP JANTXV1N4983US/TR

This series of SMT Zener voltage regulators complies with MIL-PRF-19500/356 military specifications, making them ideal for high-reliability applications where failures cannot be tolerated. These industry-recognized 5-watt Zener voltage regulators are hermetically sealed using a void-free glass construction with internal metallurgical bonding. The series includes Zener selections with a standard tolerance of 5% and voltage ranges from 3.3V to 390V, as well as tighter tolerance options identified by different suffix letters on the part number. By removing the "US" suffix, they are also available in axial-lead packages for through-hole mounting (refer to separate datasheets for 1N4954 to 1N4996, 1N5968 to 1N5969, and 1N6632 to 1N6637). Microsemi also offers a wide range of additional Zener products to meet higher and lower power rating requirements in both through-hole and SMT packages.
