What is the difference between Opto-MOSFET Relays and Solid State Relays? - FAQs | Bright Toward Industrial Co., LTD.

Both Opto-MOSFET Relays and Solid State Relays refer to a contactless design. Unlike mechanical relays or reed relays, Bright Toward's Opto-MOSFET Relays or Solid State Relays use either a MOSFET or a Triac to switch on and off. This design avoids contact wear and theoretically extends the relay's life forever, as long as it is not over-driven by current or voltage. For detailed differences, please refer to the following:Opto-MOSFET Relay by Bright Toward consists of a LED (Light Emitting Diode), a PVG (Photo Voltage Generator), and two MOSFETs. The LED inside the relay starts to emit light when a driving voltage is given. The PVG then detects the light and drives the MOSFETs, turning on the relay within microseconds. Please refer to the below products for our most popular Opto-MOSFET Relays. For more Opto-MOSFET Relays, please refer to our product page and select your desired specifications. Manufacturer of Opto-MOSFET Solid State Relays, Reed Relays, and RF MEMS Switches. We mainly serve the Semiconductor Testing, ATE, BMS (Battery Management Systems), industrial machinery and Electric Vehicle industries.
