POWER GENERATION DIODES
Plastic package Surface Mount step recovery diodes
PLASTIC PACKAGE SURFACE MOUNT S.R.D.
Description
Our SRD diodes are also available in plastic package. They incorporate a passivated mesa technology.
This family is designed for a low cost medium to high volume market that may be supplied in tape
and reel for automated pick and place assembly on surface mount circuit boards.
Application
The DH54X series support fast switching and multiplier applications:
•
•
•
•
very short pulse generation
ultra fast waveform shaping
comb generation
high order multiplication at moderate power ratings.
Temperature ranges
Operating junction (Tj) : -55°C to +125°C
