STATIC ELECTRICAL CHARACTERISTICS

Pulse test :

* tp=5ms,

δ <2%

** tp = 380 µs,

δ <2%

To evaluate the maximum conduction losses use the following equation :

P=0.54xIF(AV) + 0.0086 x IF

(RMS)

δ=tp/T

δ = 1

δ = 0.5

δ = 0.2

δ = 0.1

δ = 0.05

temperature (

δ=0.5, per diode).

When the diodes 1 and 2 are used simultaneously :

∆ Tj(diode 1) = P(diode1) x Rth(j-c)(Per diode) + P(diode 2) x Rth(c)
