Silicon Step Recovery Diodes (SRD)
The Aeroflex / Metelics MSD-700 Series Step Recovery Diodes are epitaxial silicon varactors which provide high output power and efficiencies in harmonic generator applications. Strict material and process controls result in high reproducibility. A unique silicon dioxide passivation process assures greater stability, reliability and
low leakage currents at high temperatures.
Diodes are available in various capacitance ranges for each of the 4 voltage ratings. These diodes represent the lowest transition times (snap time) available for each voltage rating. Unless otherwise specified, capacitance will be within the range shown above for each type. A capacitance tolerance of ± 10% is available at an additional charge. Diodes can be optimized for custom electrical or mechanical specifications. Custom parameters for capacitance, voltage, transition time, series resistance, etc.
are available upon request.
- Wide Selection of Tightend Capacitance Ranges
- Low Transition Times
