Philips Semiconductors Product specification
High-speed double diode BAS56
FEATURES
• Small plastic SMD package
• High switching speed: max. 6 ns
• Continuous reverse voltage:
max. 60 V
• Repetitive peak reverse voltage:
max. 60 V
• Repetitive peak forward current:
max. 600 mA.
APPLICATIONS
• High speed switching in e.g.
surface mounted circuits.
DESCRIPTION
The BAS56 consists of two highspeed switching diodes fabricated in
planar technology, and encapsulated
in the small rectangular plastic SMD
SOT143 package. The diodes are not
connected.
