Coming from my country, these are really hard to get and shipping cost is crazy. Is there any other mosfet i could use for a series box that are safe? Ive tried local electronic stores for that mosfet and bringing the diagrams in but no luck. Ill admit ive been trying to understand how to read and choose but im really confused and dont want to get a wrong one and have a mod blow off in my face. Hope you guys could help.
