The TLP320-2 is a small outline photorelay manufactured by Toshiba Semiconductor and Storage. It's designed for applications requiring electrical isolation between the control circuit and the load circuit. It features a gallium arsenide infrared emitting diode (LED) as the input stage, which is optically coupled to a MOSFET array on the output side.

Applications

• Industrial control systems
• Programmable logic controllers (PLCs)
• Telecommunications equipment
• Security systems
• Office automation equipment
• Measuring instruments

Features

• Small outline package (SOP): Allows for high-density mounting.
• High isolation voltage: Provides robust electrical isolation between the input and output.
• Low on-resistance: Minimizes power dissipation and voltage drop across the switch.
• High operating temperature: Ensures reliable operation in a wide range of environments.
• AC/DC operation: Suitable for both AC and DC load switching.
• Low input control current: Compatible with low-power control circuits.

Benefits

• Enhanced system safety: The high isolation voltage protects sensitive control circuitry from high voltage transients and surges in the load circuit.
• Reduced power consumption: The low on-resistance minimizes power loss in the switch, improving energy efficiency.
• Increased reliability: The robust design and high operating temperature ensure long-term reliability in demanding applications.
• Compact design: The small outline package saves valuable board space.
• Simplified circuit design: The integrated design simplifies circuit design and reduces component count.
