JEDEC type numbers listed indicate a tolerance of +/-20% with guaranteed limits on only VZ, IR, and VF. Devices with 21 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. 1 N NOTES: 5 1. The electrical characteristics are measured after allowing the device to stabilize for 20 seconds when mounted with a 3/8” (10 mm) minimum 2 8 lead length from the case. 1 B 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 ,e 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, 3 thereby eliminating unstable units. Also see MicroNote 202 for variation in dynamic impedance with different operating currents. D O 3. Temperature coefficient (α ). Test conditions for temperature coefficient are as follows: VZ - a. IZT = 7.5 mA, T1 = 25oC, T2 = 125oC (1N5221A, B thru 1N5242A, B). 35 b. I = Rated I , T = 25oC, T = 125oC (1N5243A, B thru 1N5281A, B).
