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