What does the “Ron” or “On Resistance” value mean in the Opto-MOS Relay data sheet?

Bright Toward Industrial Co., Ltd is a manufacturer of Solid State Relays, Reed Relays and MEMS Switches.

What does the “Ron” or “On Resistance” value mean in the Opto-MOS Relay data sheet?

Lower resistance makes the current flow less difficult.

The “Ron” or “On-Resistance” value in the data-sheet refers to the resistance value between the drain and the source of the relay during operation.

Our Opto-MOSFET Relays can provide ultra-low on-resistance down to 0.02Ω.

Opto-MOSFET Relays With Low On-Resistance Values:
  • 28 Series: 40V/4.5A/0.02Ω
  • 42 Series: 60V/2A/0.02Ω
  • 24 Series: 40V/3.5A/0.027Ω
  • 26 Series: 40V/3.5A/0.033Ω
  • 36 Series: 60V/2.5A/0.07Ω
  • 38 Series: 650V/800mA/1Ω
  • 52 Series: 1700V/350mA/2.2Ω
