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
High Speed Logic Ground Isolation Replace Slower Speed Optocouplers Line Receivers Power Transistor Isolation Pulse Transformer Replacement Switch Mode Power Supplies High Voltage Insulation Ground Isolation – Analog Signals

Notes
1. Current Transfer Ratio (CTR) as a percentage is defined as the ratio of output collector current (IO) to the forward LED input current (IF) times 100
2. A 0.1µF or bigger bypass capacitor for VCC is needed as shown in Figure 1 on following page 3. The 1.9KΩ load represents 1TTL unit load of 1.6mA and the 5.6KΩ pull-up resistor.
