VOIDLESS HERMETICALLY SEALED
500mV GLASS ZENER DIODES
Qualified per MIL-PRF-19500/533
Qualified Levels:
JAN, JANTX, JANTXV
and JANS
DESCRIPTION
This Zener voltage regulator series is military qual i fied and is ideal for hi gh-reliability
applications where a failure can not be tolerated. T hese industry-recognized 0.5 watt Zener
voltage regul ators are hermeticall y sealed with v oi dless-glass construction using an internal
metallurgical bond. It includes Zene r selections from 2.4 to 200 volts in standard 5%
tolerances as well as t i ghter 1% and 2% tolerances. They are also available i n axial leaded
packages. Micro semi also offers num erous other Zener products to meet higher and lower
power ratings i n both thru-hole and surface mount packages.
B-SQ Melf Package

NOTES:
1. Standard voltage tolerance is 5 percent. Tighter tolerances are available in plus/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.
