Diode Arrays FAQ

What is the maximum allowable case temperature?

The maximum allowable case temperature depends on the output current; it ranges up to 150°C at lower currents but decreases as the output current increases.

How does the output current vary with ambient temperature?

At an ambient temperature of 45°C, the output current is 58 A with heatsink KM 11 and 75 A with heatsink KM 33. At 35°C with active cooling (KM 33), it reaches 104 A.

What is the insulation test voltage specification?

The insulation test voltage is 3.0 kV RMS at 50 Hz for 1 minute, or 3.6 kV RMS at 50 Hz for 1 second.
