Philips Semiconductors Product specification

High-speed double diode BAW56W

FEATURES

• Very small plastic SMD package

• High switching speed: max. 4 ns

• Continuous reverse voltage:

max. 75 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 BAW56W consists of two
high-speed switching diodes with
common anodes, fabricated in planar
technology, and encapsulated in the
very small SOT323 plastic SMD
package.
