1. [Amps] MOSFET ratings (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Sun, 17 Jul 2011 18:36:51 +0000; 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; /archives//html/Amps/2011-07/msg00205.html (8,185 bytes)
2. Re: [Amps] MOSFET ratings (score: 1): Author: Steve Thompson <g8gsq72@gmail.com>; Date: Sun, 17 Jul 2011 23:11:16 +0100; 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; /archives//html/Amps/2011-07/msg00211.html (8,161 bytes)
3. Re: [Amps] MOSFET ratings (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Mon, 18 Jul 2011 16:58:51 +0000; 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; /archives//html/Amps/2011-07/msg00216.html (10,620 bytes)
4. Re: [Amps] MOSFET ratings (score: 1): Author: Steve Thompson <g8gsq72@gmail.com>; Date: Mon, 18 Jul 2011 23:15:23 +0100; 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; /archives//html/Amps/2011-07/msg00217.html (8,366 bytes)
5. Re: [Amps] MOSFET ratings (score: 1): Author: Ron Youvan <ka4inm@tampabay.rr.com>; Date: Mon, 18 Jul 2011 22:59:47 -0400; 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; /archives//html/Amps/2011-07/msg00220.html (8,115 bytes)
6. Re: [Amps] MOSFET ratings (score: 1): Author: Manfred Mornhinweg <manfred@ludens.cl>; Date: Tue, 19 Jul 2011 22:04:27 +0000; 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; /archives//html/Amps/2011-07/msg00222.html (9,679 bytes)
