1. Applications
• Mechanical relay replacements
• Security Systems
• Measuring Instruments
• Factory Automation (FA)
• Amusement Equipment
• Smart Meters
• Electricity Meters
2. General
The TLP240A and TLP240AF photorelay consist of a photo MOSFET optically coupled to an infrared LED. They
are housed in a 4-pin DIP package. They provide an isolation voltage of 5000 Vrms, making them suitable for
applications that require reinforced insulation.
