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. _www.mccsemi.com_ _Revision: 2 2006/05/28_ **2 of 5** ## **1N** 5221 thru 1N5267 **==> picture [31 x 8] intentionally omitted <==** **----- Start of picture text -----**
