DESCRIPTION
APPEARANCE
The popular 1N5221 thru 1N5281B series of 0.5 watt Zener Voltage
Regulators provides a selection from 2.4 to 200 volts in standard 5% or 10%
tolerances as well as tighter tolerances identified by different suffix letters on
the part number. These glass axial-leaded DO-7 Zeners are also available
in various military screening levels by adding a prefix identifier as described
in the Features section. Microsemi also offers numerous other Zener
products to meet higher and lower power applications.

*JEDEC registered data. JEDEC type numbers listed indicate a tolerance of +/-20% with guaranteed limits on only VZ, IR, and VF. Devices with
guaranteed limits on all six parameters are indicated by suffix A for +/-10% tolerance and suffix B for +/-5% tolerance. Also available with suffix C
or D which indicates 2% and 1% tolerance respectively.
NOTES:
1. The electrical characteristics are measured after allowing the device to stabilize for 20 seconds when mounted with a 3/8” (10 mm) minimum
lead length from the case.
2.
The zener impedance is derived from the 60 Hz ac voltage that results when an ac current having an rms value equal to 10% of the dc zener
current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to ensure a sharp knee on the breakdown curve,
thereby eliminating unstable units. Also see MicroNote 202 for variation in dynamic impedance with different operating currents.
3. Temperature coefficient (αVZ). Test conditions for temperature coefficient are as follows:
a.
I
ZT = 7.5 mA, T1 = 25oC, T2 = 125oC (1N5221A, B thru 1N5242A, B).
b. IZT = Rated IZT, T1 = 25oC, T2 = 125oC (1N5243A, B thru 1N5281A, B).
(Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temp.)
