SDN136

Analog High Speed Optocoupler

1MBd, Photodiode with Transistor Output

Description

The SDN136 is a high speed optocoupler consisting of an

infrared GaAs LED optically coupled through a high

isolation barrier to an integrated high speed transistor and

photodiode.

Separate access to the photodiode and transistor allow

users to reduce base-collector capacitance, enabling much

higher switching speeds. Signals with frequencies of up to

2.0MHz can be switched, giving the SDN136 a much

broader application range than traditional optocouplers.

The SDN136 comes standard in an 8 pin DIP package.
