The Toshiba TLP521-4G is an optocoupler designed to provide galvanic isolation between circuits. It consists of a gallium arsenide infrared emitter diode optically coupled to a photo-transistor. This device is suitable for applications requiring isolation, such as switch mode power supplies and relay driver boards.
Key electrical specifications include an input diode forward voltage of 1.25V, a maximum input diode reverse voltage of 5V, and an emitter-collector voltage of 7V. The optocoupler offers an isolation voltage of 2500Vrms. The collector-emitter voltage is rated at a maximum of 55V, with a maximum collector current of 50mA. It operates with a cut-off frequency of 80 kHz, a typical rise time of 2µs, and a typical fall time of 3µs.
Thermal characteristics include a maximum junction temperature of 125°C and a total device dissipation of 150mW. The TLP521-4G is available in DIP through-hole packages, with options for 4-pin, 8-pin, and 16-pin configurations. Its design is useful for isolating noisy signals from digital electronics, making it a valuable component for circuit isolation needs.
