Hello all, so glad I found All-About-Circuits!!
What an incredible resource!!!
Thanks in advance to anyone helping me...
I am using a TIP31 bipolar junction transistor to take an incoming audio signal and have the decibel level drive an LED. I need to prevent the LED from exploding should someone accidentally plug in CV or a cranked signal. I think what I need is a clipping diode circuit however I am not sure how to figure out what values I need nor how to set it up. I am using a standard 3mm white LED and cannot find information as to what it's maximum V rating is. If I knew that I could set the clipping diode circuit up to clip the incoming signal down into safer territory.
Has anybody had any experience with using clipping diode circuits?
Thanks kindly and take care,
dawn
