Re: Rectifiers

Hi,

Placing rectifiers in parallel is not a good idea. Here's why.
Silicon rectifiers have a negative temperature co-efficient, (-
2.2mV/degree C). What that means is the hotter they get, the lower
the voltage drop across the diode. This results in "current hogging",
where the hotter rectifier carries most of the current, making it
even hotter until it burns out.
