Suffix A denotes 5% tolerance device, no suffix A denotes 10% tolerance device
V(BR) measured after IT applied for 300 s IT=square wave pulse or equivalent
For bidirectional type having VWM of 10 volts and less, the ID limit is doubled
For bidirectional use C or CA suffixs for all types, electrical characteris apply in both directions
