1N4460US thru 1N4496US 1N6485US thru 1N6491US VOIDLESS-HERMETICALLY-SEALED SURFACE MOUNT 1.5 WATT GLASS ZENER DIODES SCOTTSDALE DIVISION APPEARANCE This surface mount Zener Voltage Regulator series is military qualified to MILPRF-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 voidless-glass construction using an internal metallurgical bond. It includes Zener selections from 3.3 to 200 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. They are also available in axial-leaded packages (see separate data sheet for 1N4460 thru 1N4496 and 1N6485 thru 1N6491). Microsemi also offers numerous other Zener products to meet higher and lower power ratings in both thru-hole and surface mount packages. "A" Package (or "D-5A") WWW .

Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK). Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a specified rms current modulation (typically 10% of IZT or IZK) and superimposed on IZT or IZK respectively. Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current. Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating. Maximum Zener Surge Current: The nonrepetitive peak value of zener surge current at a specified wave form. Microsemi Scottsdale Division 8700 E. Thomas Rd.
