1- Non-repetitive current pulse, per Fig.3 and derated above TA = 25°C per Fig. 2
2- Mounted on copper pad area of 1.6 x 1.6” (40 x 40mm) per Fig. 5
3- Measured on 8.3ms single half sine-wave or equivalent square wave, duty cycle = 4 pulses per minute maximum
4- VF = 3.5V for 1.5KE200(A) & below; VF = 5.0V for 1.5KE220(A) & above
Devices for Bidirectional Applications:
1- For bi-directional, use C or CA suffix for types 1.5KE6.8 thru types 1.5KE440A(e.g. 1.5KE6.8C, 1.5KE440CA).
2- Electrical characteristics apply in both directions.
