Photo MOSFET Solid-state Relay Features High Current Rating of 800mA

PublishTime： 2021-07-01 Article Source：Hualian Electronics

The photo MOSFET solid-state relay HSSR-S1A08-2 consists of an AlGaAs infrared emitting diode input stage optically coupled to a high-voltage output detector circuit. The detector consists of a high-speed photovoltaic diode array and driver circuitry to switch on/off two discrete high voltage MOSFETs. The relay action with a minimum input current of 5mA through the input LED. The relay reset with an input voltage of 0.8V or less.
