Description
This Zener voltage regulator series is military qualified to MIL-PRF-19500/533 and is ideal for high reliability applications where a failure cannot be tolerated. These industry-recognized 0.5 W zener voltage regulators are hermetically sealed with voidless-glass construction using an internal metallurgical bond. It includes zener selections from 2.4 to 110 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. VPT Components also offers numerous other zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.
Axial
Applications / Benefits
• Hermetically sealed glass case. • Regulates voltage over a broad operating current
and temperature range • Extensive selection from 2.4 to 110 V • Standard voltage tolerances are +/-5% with no
suffix • Tight tolerances available in +/-2% or 1% with
C or D suffix respectively • Extremely robust construction • Nonsensitive to ESD per MIL-STD-750
