- Hi all, Over the last days I have been experimenting with low cost switching MOSFETs pressed into RF power amp service. The results are quite encouraging, such as 100 watts of pretty clean output (an

- One cross reference for the IXYS transistor you mention is STP4NK80Z. If you look at the ST datasheet, it shows the lower dV/dt as applying to the MOSFET diode and two different circuits for test/mea

- Steve, Yes, that's right. But a MOSFET's internal diode is impossible to separate from the MOSFET. So if the diode is limited to 5 V/ns slew rate or so, then I can't see how the entire MOSFET could h

- OK Manfred. Firstly, I should stress that you must not confuse me with someone who understands all about these MOSFETs :-) Your question spurred my interest. I have been reading from my old (1987) IR

- If the diode is for protection, it doesn't effect the operation until the diode/s starts to conduct. Therefor the device has speed limitations when it is over driven and different speed limitations w

- Steve, No problem! We are among hams here. Yes, that make sense. I found an application note that says basically the same. It's AN2626 from STMicroelectronics, available on st.com. So I think that I
