Photo MOSFET Solid-state Relay with Very Low On-Resistance of 0.5Ω
Hualian's photo MOSFET solid-state relay HSSR-41A05-× 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.
