Power module for class A single ended amplifier
I have a pair of these power modules, i know these are for industrial power use rated for 500A Ic and 2500Pd . i know it would be non linear in characteristic curves BUT can i use it say for 10A conitnous IC for 60V supply via a 8 ohm resistive load or current drain Power mosfet so i will get around 100W single ended class A amp.
The module is ID500A-030 by mitsubishi. Please note that i already have a spare pair of these with some serious heat sinks and swithcing mode power supply available. regards
here is the pdf file for the module
The SOA on that part for linear use is horrible, 150W at 30V.
The $2 MJ15015 is better, it has 180W SOA at 60V.
The $3 MJ21194 has 250W SOA at 60V, and is faster than the MJ15015.
I have about 600 pcs of 2N6274 that are equally horrible for linear use. Rated at 50A and 30Mhz they have about 30W SOA at 30V. This part was about $40 (30 years ago) as an MRO part, and is about $300 today for mil-qualified use (we use these at work). At $300 each, 600 pcs of these would theoretically be worth $180,000. I made a big mistake when I bought them for $1 each. I saw this part in a cheap 12V power supply used as a pass transistor, that's about all they're good for.
