lawcuenca Posted June 16, 2011 Report Share Posted June 16, 2011 Hi,Attached is the configuration for the subject. Here are the datasheet values:IF = 2APT = 21WVF = 9.07V @I=20APlease advise on what zener diode I can use for this.Thanks,Law Quote Link to comment Share on other sites More sharing options...

lawcuenca Posted June 17, 2011 Author Report Share Posted June 17, 2011 Attached is the datasheet for the circuit I am talking about. I just want to know how they were able to determine the values for the boost inverse diode (diode clamp).Thanks,LawFZ06NPA070FP-P969F-14.pdf Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 17, 2011 Report Share Posted June 17, 2011 In order to help you, we need a full schematic of your intended application. Quote Link to comment Share on other sites More sharing options...
lawcuenca Posted June 21, 2011 Author Report Share Posted June 21, 2011 The schematic is within the datasheet I attached in my second post. Will appreciate your help. Thanks!Regards,Law Quote Link to comment Share on other sites More sharing options...
lawcuenca Posted June 21, 2011 Author Report Share Posted June 21, 2011 Nonetheless, I have attached the schematic for reference. Quote Link to comment Share on other sites More sharing options...
Hero999 Posted June 21, 2011 Report Share Posted June 21, 2011 I have read the datasheet.It's not a complete working inverter. It needs other components to make it work. You can't just wire it up and expect it to work. We need the complete circuit to help. Quote Link to comment Share on other sites More sharing options...
lawcuenca Posted June 23, 2011 Author Report Share Posted June 23, 2011 I just want to know what is the significance of each of the parts is because when i looked up the datasheet, i can't understand how they were able to come up with the values for the boost inverse diodes. Looking at it, it is a zener clamp. Now, I am assuming that the specified voltage drop in the datasheet is the series combination of the FWD forward voltage drop and the zener voltage of the series zener diode. The purpose of this is that I want to identify what particular diodes are used in this. Would it work if I replace the zener with a TVS diode? or is it a TVS diode right from the start and my assumptions are incorrect? Quote Link to comment Share on other sites More sharing options...
