mtaj50n05hd Substitue?

jordan_ciaramit · 23rd June 2011, 03:44 AM

Okay I have 2 amps that use these for the power supply that need to be replaced. One is a old sony and the other a old kenwood. I put irfz44n in the sony and seems to be working fine on the bench but im afraid to put it under a load bc I cant find datasheets on the MTAJ50N05HD to see the values. The subs also need to be available in a TO-220FP (solid plastic case) bc they bolt directly to the heatsink in both amps, I could modify how these mount if needed but would rather not.

I generally use the IRFIZ48 and have never had a problem with them.
IRFIZ48GPBF Vishay/Siliconix MOSFET Power

Someone suggested the following (or something very similar) and these should work if the value of the gate resistors was low enough.
Digi-Key - 497-3193-5-ND (Manufacturer - STP55NF06FP)

What was the model of each amp?
