The H11A617BS is a single channel transistor output optocoupler. It has a forward voltage of 1.35V and a maximum Vce saturation of 400mV. The isolation voltage is 5300Vrms which makes it suitable for high voltage applications. It has a minimum DC current transfer ratio of 63% and a maximum of 125% at 10mA. The switching turn-on and turn-off time is not specified, but the rise and fall time is 2.4μs. The maximum output voltage is 70V and channel output current is 50mA. It has a continuous forward current max of 50mA. The package is 4-SMD and it is obsolete (EOL). The temperature range for operating is -55°C to 100°C. This optocoupler is widely used in applications such as motor control, power supply regulation, and industrial controls.
