Product specification

High-speed double diode

BAS28

FEATURES

• 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 BAS28 consists of two

high-speed switching diodes,

fabricated in planar technology, and

encapsulated in the small plastic

SMD SOT143 package. The diodes

are not connected.
