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.
Applications
