TLP3553A,TLP3553AF
1. Applications
• Heating, ventilation and air conditioning (HVAC)
• Mechanical relay replacements
• ATE (Automatic Test Equipment)
• Factory Automation (FA)
• Security Systems
2. General
The TLP3553A and TLP3553AF photorelay consist of a photo MOSFET optically coupled to an infrared LED. It
is housed in a 4-pin DIP package. The low ON-state resistance and the high permissible ON-state current of the
TLP3553A and TLP3553AF make it suitable for power line control applications.
