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%, 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. IZT = 7.5mA, TI = 25[o] C T2 = 125[o] C (1N5221 thru 1N5242) 

- b. IZT = Rated IZT, TI = 25[o] C, T2 = 125[o] C (1N5243 thru 1N5267) 

Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
