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 (1N5221 thru 1N5242)  
I
IZT = Rated IZT, T = 25oC, T2 = 125oC (1N5243 thru 1N5267)  
I
Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.
