looks like it has, although the board just might be slow, as I got an email to say you'd replied to this thread and your message took a while to appear.

AS you got the email, it seems it went alright. If it turns up, then OK. If it doesn't by tomorrow, give me a PM and I'll redo it. I replied direct from my email box so didn't keep a copy.

I usually do those in Word and keep a copy. Wish I had that time!

 

Enclosed is the diagram to give you an idea of how it works incase your interested, its not accurate symbol wise I've just knocked it together.

I'm looking for some diodes for use in automotive circuits, but haven’t got a clue about the specification side of a diode; does the diode have to be specifically for 12V? Or can you use any diode rated above 12V? Is there a specific part number/type/make......?

Any help would be appreciated.

Diodes are rated for both voltage and current. You have already supplied the voltage used in your particular application. Does the diode you are replacing have any markings on it? What does it look like?

I forgot to include something in my reply to your question. You can always use a diode with higher voltage ratings as long as the diode will handle the amount of current for your particular application.

 

hello i m student of engineerig university would u guide me how to use his site

 

Pinball I've already solved my problem (in the diagram posted above) but thanks anyway. Went from my idea of using a diode to protect my alarm, to actually finding out that the alarm was wired different to what I though and was actually driving a relay that was firing 12V down to the solenoid, and not the solenoid direct.

Miansari you need to goto the main page and post your question in the correct topic...... http://forum.allaboutcircuits.com/index.php?act=idx
