TLP2345 Description

Short technical summary and product information.

The Toshiba TLP2345 is an optocoupler designed for signal isolation applications, including Intelligent Power Modules, Programmable Logic Controllers (PLCs), and high-speed digital interfacing. It comprises a GaAlAs infrared LED coupled with a high-gain, high-speed photo detector, housed in an SO6 package.

Key electrical specifications include a supply voltage range of 4.5 V to 30 V, a maximum threshold input current of 1.6 mA, and a maximum supply current of 3 mA, contributing to energy efficiency. The device boasts a maximum propagation delay time of 120 ns and a pulse width distortion of 40 ns. It provides a guaranteed common-mode transient immunity of ±30 kV/µs due to an internal Faraday shield and offers an isolation voltage of 3750 Vrms.

This photocoupler operates within a temperature range of -40 °C to 110 °C. It features a buffer logic type with a totem-pole output stage, capable of current sourcing and sinking. The TLP2345 is suitable for surface mounting. An inverter output version, the TLP2348, is also available.
