Toshiba TLP785(GB) Optocoupler, DIP4, 25mA, 5kV, 100%

The Toshiba TLP785(GB) is a high-reliability, single-channel optocoupler featuring a transistor output and a compact DIP4 package. Designed to provide superior electrical isolation between circuits, it is an essential component for ensuring safety and signal integrity in a wide range of electronic applications. With a minimum isolation voltage of 5,000 Vrms, it offers robust protection against voltage surges and transients, making it ideal for interfacing circuits of different potentials.

This optocoupler utilises a silicone phototransistor optically coupled to an infrared emitting diode, achieving a guaranteed 100% current transfer ratio (CTR). This high efficiency ensures reliable signal transmission with minimal current loss. Key electrical specifications include a forward current of 25mA, a maximum supply voltage of 24V, and a collector-emitter voltage of 80V minimum, providing ample headroom for various switching and control tasks.

Key Features & Applications

• High Isolation: With 5kV isolation, it safely separates high and low voltage circuits, protecting sensitive components.
• Reliable Performance: A 100% CTR guarantees consistent signal transfer, while the 80V collector-emitter voltage supports a broad operating range.
• Compact & Standardised: The 7.62mm pitch DIP4 package is easy to handle and integrates seamlessly into through-hole PCB designs.
• Industry Recognised: Certified to UL 1577 and CSA standards, assuring compliance with international safety requirements.

This component is perfectly suited for enhancing the safety and functionality of office equipment, household appliances, solid-state relays, and switching power supplies. It is also widely used in various controllers and for secure signal transmission between circuits of different voltages, providing a dependable isolation barrier.
