Step Recovery Diode

 

A step recovery diode is most graphically described as a charge controlled switch. A forward bias stores charge, a reverse bias depletes this charge, and when fully depleted the SRD ceases to conduct current. The action of turning off, or ceasing to conduct current, takes place so fast that the diode can be used to create an impulse.

Step Recovery Diodes are used to make harmonic multipliers and comb generators. HP CSSD no longer manufactures Step Recovery diodes.
