1. VBR measured after IT applied for 300ms. IT=square wave pluse or equivalent. 2.For bidirectional use C or CA suffixs for all types (ex.P4KE6.8C,P4KE400CA) electrical characteristics apply in both directions. 3.For bidirectional types having Vwm of 10volts and less,the ID limit is doubled. 4.Whole voltage range is available in MELF packages.
