Frequently Asked Questions
What is the continuous drain current limit at standard temperature?
A maximum of 26 A can be handled as the continuous drain current when operating at T ≤ 25 °C.
How does the device prevent damage from overvoltage or short circuits?
It offers latched overload protection, actively clamping overvoltages above 50V and providing self-protection against short circuit loads (up to 3A).
Can this MOSFET be used with standard logic control signals?
Yes, it is designed as a logic level TOPFET, requiring only a 5 V input voltage for control.
Is the BUK101-50GL safe for life support environments?
No, the document explicitly states these products are not designed for use in life support appliances or systems.
