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