Frequently asked questions
What is the price of TLP785 Phototransistor Optocoupler 5000Vrms Isolation in Egypt?
TLP785 Phototransistor Optocoupler 5000Vrms Isolation currently costs 12 EGP in Egypt.
Where can I buy TLP785 Phototransistor Optocoupler 5000Vrms Isolation in Egypt?
TLP785 Phototransistor Optocoupler 5000Vrms Isolation is available from Makers Electronics. Compare the offers above to find the best price.
How should I drive the LED side?
Drive the input LED through a series resistor from your supply. The listed switching times are specified at 2 mA LED current, so using a similar current gives predictable timing.
Does the output need an external resistor?
Yes. As a phototransistor output, it needs an external pull-up resistor to produce a logic-level signal. The output is limited to 50 mA, so do not connect heavy loads directly.
