I second ebp's suggestion to use a Zener plus regular diode between the drain and gate of the MOSFET, but you should use a MOSFET with a higher voltage rating. Using a 30V MOSFET with a 24V supply doesn't give you much margin. I suggest at least a 50% margin or a MOSFET with a … TīmeklisZener diodes are used for protection on DC supplies (unidirectional) as they behave like normal diodes in their forward biased direction, but break down and conduct in their reverse biased direction. Thus a zener diode’s reverse breakdown voltage, V Z can be used as the reference or clamping voltage level. bmw screensaver download
