Hello all, I need to verify a power Mosfet for a Clarion A2000 car amp I am repairing. It reads MT 5P, 0N05E, (M) 342 I did a search and came up with this was a Motorola No. Now owned by ON Semiconductor and new no. is MTP50P03HDLG being a P-Ch Mosfet 30V at 50A 25 Mega Ohms. This is a digikey no. I came up with is this correct? One of them was blown apart and another was cracked. There are 6 total and I am going to replace them all because they all tested between 3 and 49 ohms and should be in high mega ohms. Digikey wants $4 ea for these. Is there a another safe supplier where I don't get counterfeit ones? Thanks
