All diodes can be converted into Smoke Emitting Diodes with the proper circuit. Simply conntect the diode in reverse to its manufacturer's recommendations and provide sufficient voltage and current.

If done properly, this method can yield large quantities of smoke. If done enthusiastically, this method can also yield micro-lightning (sparks. If done to excess, this method can yield fire.

Unfortunately, this connection method also turns the diode into a one-shot.
