Frequently Asked Questions
What is the maximum continuous drain-source voltage?
The maximum continuous drain source voltage (VDSS) is 50 V.
Does the TOPFET provide overload protection?
Yes, it provides overload protection by means of drain current limiting and activating overtemperature protection. It remains latched off until reset by the input.
What happens if there is an overvoltage transient at the drain source?
The power MOSFET actively turns on to clamp overvoltage transients, providing clamping energy (E) up to 100 mJ for inductive loads.
How can I calculate the thermal resistance when mounted on a PCB?
When mounted on any PCB, the thermal resistance junction to board (thj-b) is typically between 40 and 70 K/W.
