Frequently Asked Questions
Can this TOPFET be used in life support systems?
No, these products are not designed for use in life support appliances, devices or systems.
What is the continuous drain-source voltage rating (DSS)?
The maximum continuous off-state drain source voltage (VDS) is 50 V.
How does the device provide protection against overvoltage?
At a drain source voltage above 50 V, the power MOSFET actively turns on to clamp overvoltage transients.
What are the required components for overload protection?
Two types of overload—quick discharge and over temperature—require specific circuit conditions or attached resistors (e.g., R ≥ 2 kΩ).
Does the device have ESD protection or is it intended for low voltage operation?
It includes ESD protection on input, flag, and protection supply pins.
