Photocouplers Photorelay
TLP3122A
TLP3122A
1. Applications
• Measuring Instruments
• Security Systems
• ATE (Automatic Test Equipment)
• Factory Automation (FA)
• Battery Management System (BMS) (Non-Automotive)
• Programmable Logic Controllers (PLCs)
• Mechanical relay replacements
2. General
The Toshiba TLP3122A consists of a gallium arsenide infrared emitting diode optically coupled to a photo-
MOSFET in a 4-pin SO6 package. This photorelay has higher output current rating than phototransistor-type
photocoupler; hence, it is suitable for use as On/Off control for high current.
