Broadcom's ASSR-601J 1500 V high-voltage, 1 Form A (industrial photo MOSFET)

Broadcom's ASSR-601J is a photo MOSFET that is designed for high-voltage industrial applications. The ASSR-601J consists of an AlGaAs infrared light-emitting diode (LED) 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 photo MOSFET turns on (contact closes) with a minimum input current of 10 mA through the input LED. The photo MOSFET turns off (contact opens) with an input voltage of 0.4 V or less. Leveraging Broadcom’s galvanic isolation optocoupler technology, the ASSR-601J provides reinforced insulation and reliability that delivers safe signal isolation critical in high-temperature industrial applications.
