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.
