Notes:
5. Non-Repetitive current pulse as shown in figure 2 and derated above T A = +25°C as per figure 1.
6. Non-Repetitive current pulse as shown in figure 3 and derated above T A = +25°C as per figure 1.
7. I FSM = 40A for DFLT170A and DFLT220A; I FSM = 50A for all other voltages.
8. 1/2 sine wave (or equivalent square wave), pulse width = 8.3ms, duty cycle = 4 pulses/minute maximum.
9. Device mounted on 1"x1", FR-4 PCB; 2 oz. Cu pad layout. Cathode pad dimensions 5.5mm x 3.5mm. Anode pad dimensions 2.25mm x 3.5mm.
10. Theoretical R ? JS calculated from the top center of the die straight down to the PCB/cathode tab solder junction.
11. V BR measured at pulse test current I T with tp ? 5.0ms at T A = +25°C.
