High-speed double diode 1PS301
FEATURES
• Very small plastic SMD package
• High switching speed: max. 4 ns
• Continuous reverse voltage:
max. 80 V
• Repetitive peak reverse voltage:
max. 85 V
• Repetitive peak forward current:
max. 500 mA.
APPLICATIONS
• High-speed switching in e.g.
surface mounted circuits.
DESCRIPTION
The 1PS301 consists of two
high-speed switching diodes with
common cathodes, fabricated in
planar technology, and encapsulated
in the very small rectangular plastic
SMD SC70-3 package.
