NOTE 1: Table as shown lists type numbers, which indicate a tolerance of ±20% with guaranteed limits on only Vz, IR, and V F. Devices with
guaranteed limits on all six parameters are indicated by suffix “A” for ±10%, “B” for ±5%, “C” for ±2% tolerance
NOTE 2: The electrical characteristics are measured after allowing the device to stabilize for 20 seconds.
NOTE 3: Temperature coefficient (áVZ). Test conditions for temperature coefficient are as follows:
IZT = Rated IZT, TI = 25oC T2 = 125oC
Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
