Digsy Posted May 20, 2002 Share Posted May 20, 2002 Calling all electrical boffins. I need a diode, but I've forgotten almost all my college electronics so I can't remember how they are defined. I need one that will stop a current of 2A flowing in the wrong direction in a 12V circuit. What do I need to ask for at my local Maplin's?

Matt Harwood Posted May 20, 2002 Share Posted May 20, 2002 A 3 amp diode? - Probably cost you all of 20p if they''l sell them separatly. If you want, give me a call and I'll send you a couple. 01622 683044 Quote Link to comment Share on other sites More sharing options...
Digsy Posted May 20, 2002 Author Share Posted May 20, 2002 Hi Matt. I did a quick websearch during my lunch break (so as not to take up useful work time when I browse the BBS) and reminded myself about all the diode specs. Forward voltage drop, breakdown voltage, leakage current, etc, etc. Even that s-shaped current v voltage graph. Brought it all back to me, happy student days breathing solder flux, jumpers for goalposts... Anyway, you are quite right, its nothing too bewildering after all. It will probably cost you more than the parts are worth in postage and time, and I'm off to the electrics store this week anyway, so I won't bother you just yet unless they don't have the goods. Thanks for the kind offer though! PS. I've sent you a PM about something else. Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted May 20, 2002 Share Posted May 20, 2002 The offers there if you want it... I'm sure I can spare about 35p for the stamp, envelope and diodes togerther! And... you have mail... Quote Link to comment Share on other sites More sharing options...
