DESCRIPTION

APPEARANCE

The 1N5221BUR thru 1N5281BUR series of 0.5 watt Zener Voltage

Regulators provides a surface mount equivalent to the popular JEDEC

registered 1N5221B to 1N5281B for 2.4 to 200 volts in standard 5%

tolerances as well as tighter tolerances identified by different suffix letters on

the part number. These are also available with an internal-metallurgical-

bond option by adding a “-1” suffix (see separate data sheet). Microsemi

also offers numerous other Zener products to meet higher and lower power

applications.

DO-213AA

NOTE 1: Table as shown lists type numbers, which 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%, “B” for +/-5%, “C” for +/-2%, and “D” for +/-1% tolerance.

NOTE 2: The electrical characteristics are measured after allowing the device to stabilize for 20 seconds.

NOTE 3: Temperature coefficient (α_vz). Test conditions for temperature coefficient are as follows:

_ZT= 7.5 mA, T₁= 25^oC,

T₂= 125^oC (1N5221AUR & BUR thru 1N5242AUR & BUR)

b. I_ZT= Rated I_ZT, T₁= 25^oC,

T₂= 125^oC (1N5243AUR & BUR thru 1N5281AUR & BUR)

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

NOTE 4: These devices may be ordered as either 1N5221UR thru 1N5281BUR or as MLL5221 thru MLL5281B part numbers.
