1N4460 1N4496 and 1N6485 1N6491 Qualified Levels: VOIDLESS HERMETICALLY SEALED 1.5 WATT JAN, JANTX, Available on GLASS ZENER DIODES JANTXV and JANS commercial versions Qualified per MIL-PRF-19500/406 DESCRIPTION This Zener voltage regulator series is military qualified to MIL-PRF-19500/406 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 1.5 watt Zener voltage regulators are hermetically sealed with void-less glass construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 200 volts in standard 5% tolerance. 1% and 2% tolerance versions are also available. Microsemi also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages.

Z Z 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 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. ZT ZK ZT ZK V Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. F Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and I R temperature. Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating. I ZM Maximum Zener Surge Current: The non-repetitive peak value of Zener surge current at a specified wave form. I ZSM T4-LDS-0183, Rev. 3 (120901) 2012 Microsemi Corporation Page 2 of 6
