NOTE 4:

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

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

Temperature coefficient ( vz). Test conditions for temperature coefficient are as follows:

a. IZT = 7.5 mA, T1 = 25oC,

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

b. IZT = Rated IZT, T1 = 25oC,

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

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

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