Note:

( 1 ) VBR measured after It applied for 300 ms., It = square wave pulse or equivalent.

( 2 ) VF = 3.5 Vmax., IF = 25 Amps. ( 6.8 Volts thru 91Volts )

VF = 5.0 Vmax., IF = 25 Amps. ( 100 Volts thru 550 Volts ) per 1/2 square or equivalent sine wave.

PW = 8.3 ms, duty cycle = 4 pulses per minute maximum.

( 3 ) For Bipolar types having VR of 10 Volts and under, the IR limit is doubled.

( 4 ) "4KE" will be omitted in marking on the diode.
