NOTE1: suffix "B" = 5% tolerance on nominal Zener voltage, suffix "C" signifies 2%.  
NOTE2: The electrical characteristics are measured after allowing the device to stabilize for 20 seconds.  
NOTE3: Temperature coefficient (áVZ). Test conditions for temperature coefficient are as follows:  
a.  
b.  
IZT = 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.
