What are the key specifications of the EL1019?

It features 5000 VRMS isolation, an 80V collector-emitter voltage, and a Current Transfer Ratio (CTR) of 200-400% at 5mA input current.

What applications is this optocoupler suitable for?

It is commonly used in switch-mode power supplies (SMPS), programmable logic controllers (PLCs), household appliances, and office equipment.

What should engineers review before using the EL1019?

Engineers should check the thermal derating curves for high-temperature operation (up to 110°C) and ensure the CTR range matches the feedback loop requirements of their design.

What is the pinout of EL1019?

Use the EL1019 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about EL1019 pinout to locate pins, power rails, and interface signals before layout.
