NOTE 1: 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
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:
a.
b.
I
ZT = 7.5mA, T = 25oC T2 = 125oC (DL5221 thru DL5242)
I
IZT = Rated IZT, T = 25oC, T2 = 125oC (DL5243 thru DL5261)
I
Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
