VF (forward voltage) = 1.2 V maximum @ IF = 200mA for all types Notes: 1. 2. 3. The zener voltage subdivision (VZ) is measured 40mS after diode is powered up. The operating resistance (Zzt and Zzk) is measured by superimposing a minute alternation current in the regulated current (Iz). When ordering, please specify tolerance A, B, C or D.
