TLP523-4 Description

Short technical summary and product information.

The Toshiba TLP523-4 is a photocoupler designed for applications such as programmable controllers, DC-output modules, and solid-state relays. It integrates a GaAs infrared emitting diode with a silicon phototransistor, featuring an integral base-emitter resistor for optimized switching speed and elevated temperature characteristics.

 

Key electrical specifications include a maximum Collector-Emitter voltage of 55V, a maximum Collector current of 150mA, and an isolation voltage of 2500Vrms. The device operates with a forward current up to 60mA and has a current transfer ratio of 500% minimum at 1mA forward current.

 

This photocoupler is housed in a DIP package suitable for through-hole mounting. It operates within a temperature range of -55°C to 100°C. The TLP523-4 provides four isolated channels per package, making it suitable for applications requiring multiple isolation points.

 

UL recognized under UL1577, file no. E67349, the TLP523-4 is designed for reliable performance in various industrial control systems.
