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 (á VZ). Test conditions for temperature coefficient are as follows: a. IZT = 7.5mA, TI = 25oC T2 = 125oC (DL5221 thru DL5242) b. IZT = Rated IZT , TI = 25oC, T2 = 125oC (DL5243 thru DL5261) Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temperature. www.cnelectr.com
