POWER GENERATION DIODES
Plastic package Surface Mount step recovery diodes
P LASTIC PACKAGE S URFACE MOUNT S .R.D.
Description
Our SRD diodes are also available in plastic package.They incorporate a passivated m esa technology.
This fam ily is designed for a low cost m edium to high volum e m arket that m ay be supplied in tape
and reel for autom ated pick and place assem bly on surface m ount circuit boards.
Application
The DH54X series support fast switching and m ultiplier applications:
• very short pulse generation
• ultra fast waveform shaping
• com b generation
• high order m ultiplication at m oderate power ratings.
