I have a similar issue. One P-Channel High Voltage Mosfet is the Pass element on a 50-200V DC linear power supply. The needed current is about 400mA but seems that most devices have a SOA very much limited in the higher voltage operation. That leads to destruction of the Mosfet if current is over 300mA or so.
The Mosfet is working in linear region and was thinking to parallel 2 of them. But do they need large balancing resistors?
Parts I test are FQP4P40. I attach the circuit I am testing.

This thread was split from Parallel mosfets or IGBT from single mosfet driver, if big enough?
