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 V_Z, I_R, and V_F. 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.

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 (I_ZTor I_ZK) is superimposed on I_ZTor I_ZK. 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 (α_VZ). Test conditions for temperature coefficient are as follows:

_ZT= 7.5 mA, T₁= 25^oC, T₂= 125^oC (1N5221A, B thru 1N5242A, B).

_ZT= Rated I_ZT, T₁= 25^oC, T₂= 125^oC (1N5243A, B thru 1N5281A, B).

(Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temp.)
