DESCRIPTION APPEARANCE

This surface mount 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 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 packa ges.

SYMBOLS & DEFINITI ONS

Symbol Definition

VZ Zener Voltage: The zener vol tage the device will exhibit at a specified current (IZ) in its breakdown region.

IZ, IZT, IZK Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK).

ZZT or ZZK 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 I ZT or IZK respectively.

VF Maximum Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.

IR Maximum Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and

temperature.

IZM Maximum Regulator (Zener) Current: The maximum rated dc current for the specified po wer rating.

IZSM Maximum Zener Surge Current: The nonrepetitive peak value of zener surge current at a specified wave form.
