Diode Arrays FAQ

What is the maximum non-repetitive surge current rating?

The maximum peak one-cycle non-repetitive surge current is 8600 A for a 5 μs sine pulse or 3 μs rectangular pulse.

How does the junction temperature affect the forward voltage drop?

The forward voltage drop decreases as the junction temperature increases; it is rated at 0.72 V at 25 °C and 0.69 V at 125 °C for 100 A.

What is the recommended mounting torque for the module?

The recommended mounting torque to the heatsink is 4 Nm ± 10 %, and the torque should be rechecked after 3 hours to allow for compound spread.
