1N6309 thru 1N6355D Qualified Levels: VOIDLESS HERMETICALLY SEALED JAN, JANTX, JANTXV Available on 500mW GLASS ZENER DIODES and JANS commercial Qualified per MIL-PRF-19500/533 versions 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.

R I , I , I Regulator Current: The dc regulator current (I ), at a specified test point (I ), near breakdown knee (I ). Z ZT ZK Z ZT ZK I Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating. ZM I Maximum Zener Surge Current: The non-repetitive peak value of Zener surge current at a specified wave form. ZSM V Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. F Working Peak Voltage: The maximum peak voltage that can be applied over the operating temperature range. This is V WM also referred to as Standoff Voltage. V Zener Voltage: The Zener voltage the device will exhibit at a specified current (I ) in its breakdown region. Z Z Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a Z or Z ZT ZK specified rms current modulation (typically 10% of I or I ) and superimposed on I or I respectively.
