JEDEC type numbers listed 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% tolerance and suffix B for +/-5% tolerance. Also available with suffix C or D which indicates 2% and 1% tolerance respectively. NOTES: 1. The electrical characteristics are measured after allowing the device to stabilize for 20 seconds when mounted with a 3/8” (10 mm) minimum lead length from the case. 2. The zener impedance is derived from the 60 Hz ac voltage that results when an ac current having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to ensure a sharp knee on the breakdown curve, thereby eliminating unstable units. Also see MicroNote 202 for variation in dynamic impedance with different operating currents. 3. Temperature coefficient (αVZ). Test conditions for temperature coefficient are as follows: o o a. IZT = 7.5 mA, T1 = 25 C, T2 = 125 C (1N5221A, B thru 1N5242A, B). o o b. IZT = Rated IZT, T1 = 25 C, T2 = 125 C (1N5243A, B thru 1N5281A, B). (Device to be temperature stabilized with current applied prior to reading breakdown voltage at the specified ambient temp.) Copyright © 2005 8-09-2005 REV D Microsemi Scottsdale Division 8700 E.
