Description
- DESCRIPTION
- This Zener Voltage Regulator series is military qualified to MIL-PRF-19500/356 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 5 Watt Zener Voltage Regulators are hermetically sealed with voidless-glass construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 390 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. They are also available in surface-mount packages (see separate data sheet for 1N4954US thru 1N4996US, 1N5968US thru 1N5969US, and 1N6632US thru 1N6637US). Microsemi also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.
- FEATURES
- • Popular JEDEC registered series
- • Voidless hermetically sealed glass package
- • Extremely robust construction
- • Triple-layer passivation
- • Internal “Category I” Metallurgical bonds for 1N4954 thru 1N4996, and “Category III” for 1N6632 thru 1N6637 as well as 1N5968 thru 1N5959
- • JAN, JANTX, JANTXV, and JANS available per MIL PRF-19500/356
- • Surface mount equivalents also available in a square end-cap MELF configuration with “US” suffix (see separate data sheet for 1N4954US thru 1N4996US, 1N6632US thru 1N6637US and 1N5968US thru 1N5969US
