Gallium Arsenide Schottky Rectifier
Second generation
Data according to IEC 60747 and per diode unless otherwise specified
Features
GaAs Schottky Diode with Enhanced
Barrier Height:
• lowest operating forward voltage drop due
to additional injection of minority carriers
• high switching speed
- low junction capacity of GaAs diode
independent from temperature
- short and low reverse recovery current
peak due to short lifetime of minority
carriers
- soft turn off
Surface Mount Packages:
• Incorporating Single and Dual Diode
Topologies
• Industry Standard Package Outlines
• Epoxy meets UL 94V-0
Applications
Switched Mode Power Supplies:
• AC-DC converters
• DC-DC converters
with:
• high switching frequency
• high efficiency
• low EMI
for use e. g. in:
• telecom
• computer
• automotive equipment
