TLP523 Description

Short technical summary and product information.

The Toshiba TLP523 is an optocoupler designed for applications such as programmable controllers, DC-output modules, and solid-state relays. It comprises an infrared emitting diode and a silicon Darlington phototransistor with an integrated base-emitter resistor.

Key electrical specifications include a minimum current transfer ratio of 500% at 1 mA forward current and a minimum isolation voltage of 2500 Vrms. The collector-emitter voltage is rated at a minimum of 55 V, with a maximum leakage current of 10 μA at 85°C.

The device operates within a temperature range of -55°C to 100°C. The TLP523 is available in various configurations, including single-channel (TLP523), dual-channel (TLP523-2) in an eight-lead DIP package, and quad-channel (TLP523-4).

This component is recognized by UL (UL 1577, File No.E67349) and cUL (CSA Component Acceptance Service No.5A File No.E67349), indicating its suitability for safety-critical applications.
