IL217AT Description

Short technical summary and product information.

The Vishay Dale IL217AT is an optically coupled pair featuring a gallium arsenide infrared LED and a silicon NPN phototransistor. It is designed to transmit signal information while maintaining high electrical isolation between input and output.

 

This optocoupler offers a high isolation test voltage of 4000Vrms and a forward current of 60 mA. The minimum current transfer ratio (CTR) is 100% at 1mA, with a typical CTR of 130%. The output is a transistor with base, and the device operates within a temperature range of -55°C to 100°C.

 

Designed for surface mounting, the IL217AT comes in an industry-standard 8-SOIC package, making it suitable for high-density applications with limited space. It is compatible with various soldering methods including dual wave, vapor phase, and IR reflow soldering.

 

Key electrical characteristics include a forward voltage of 1.5V, a reverse voltage of 6V, and a power dissipation of 240mW. The collector emitter breakdown voltage is 30V, and the collector current is 100mA. The Vce saturation voltage is 400mV.
