Diode Arrays FAQ

What is the maximum isolation voltage for the MBRF30150CT?

The isolation voltage depends on the mounting method: 4500 V for clip mounting with epoxy body away from the heatsink edge, 3500 V for clip mounting with the body inside the heatsink, and 1500 V for screw mounting with the body inside the heatsink.

How does the forward voltage drop change with temperature?

The forward voltage drop decreases as temperature increases. At 15 A, it is 1.0 V at a junction temperature of 25°C and drops to 0.80 V at a junction temperature of 125°C.

What is the typical junction capacitance of the device?

The typical junction capacitance per leg is 400 pF, measured at a reverse voltage of 5 V, a case temperature of 25°C, and a signal frequency of 1 MHz.
