VOIDLESS HERMETICALLY SEALED
500mW GLASS ZENER DIODES
Qualified per MIL-PRF-19500/533
DESCRIPTION
This Zener voltage regulator series is military qualified and is ideal for high-reliability
applications where a failure cannot be tolerated. These industry-recognized 0.5 watt Zener
voltage regulators are hermetically sealed with voidless-glass construction using an internal
metallurgical bond. It includes Zener selections from 2.4 to 200 volts in standard 5%
tolerances as well as 1% and 2% tolerances. They are also available in surface-mount
packages. Microsemi also offers numerous other Zener products to meet higher and lower
power ratings in both thru-hole and surface mount packages.

Notes:
1. At 3/8 inch (10 mm) from body. See Figure 1 and Figure 2 for derating.
2. TA = +55 °C before derating on printed circuit board (PCB), PCB = FR4 .0625 inch (1.59 mm) 1-layer 1-
Oz Cu, horizontal, still air, pads = .092 inch (2.34 mm) diameter, strip = .030 inch (0.76 mm) x 1 inch
(25.4 mm) long, axial lead length L ≤ .187 inch (≤ 4.75 mm); RΘJA with a defined thermal resistance
condition included is measured at IZ = as defined in the characteristics and ratings table herein.
