|Rth(c)|Coupling||1|°C / W|



When diodes 1 and 2 are used simultaneously: 

Tj(diode 1) = P(diode 1) x Rth(j-c)(Per diode) + P(diode 2) x Rth(c)

1. Pulse test: tp = 5 ms, δ < 2% 

2. Pulse test: tp = 380 µs, δ < 2% 

To evaluate the conduction losses use the following equation: 

P = 0.8 x IF(AV) + 0.025 IF[2] (RMS)
