Note: ( 1 ) VBR measured after IT applied for 300 µs., IT = square wave pulse or equivalent. ( 2 ) Surge Current Waveform per Figure 5 and Derate per Figure 1 ( 3 ) A Transient suppressor is normally selected according to the reverse " Stand-off Voltage " (VWM) which should be
equal to or greater then the D.C. or continuous peak operating voltage level.
