VOIDLESS HERMETICALLY SEALED
500mW GLASS ZENER DIODES
Qualified per MIL-PRF-19500/533
Qualified Levels:
JAN, JANTX, JANTXV
and JANS
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 reg ul ators are herm etic a ll y sealed with vo idl ess-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.
DO-35 or
“D” Package
Also available in:
“B” SQ MELF package
(surface mount)
1N6309US – 1N6355DUS

NOTES:
1. Standard voltage tolerance is 5 percent. Tighter tolerances are available in pl us/minus 1 and 2 percent voltage tolerances. (See part
nomenclature.)
2. Voltage regulation VZ(reg) is the measured voltage change at thermal equilibrium between the current of 10% and 50% of maximum Zener
current IZM when the lead temperature is maintained at 25 °C =+8 °C, -2 °C.
