What is PhotoMOS relay?
A PhotoMOS is a semiconductor relay with an LED as an input and MOSFET as an output. It is used in various fields to improve device reliability and reduce size.
What is OptoMOS?
The OptoMOS® line of solid state relays uses discrete semiconductor components and the patented OptoMOS architecture to deliver fast, reliable, bounce-free switching in a compact design. And the common-input OptoMOS relays provide a design alternative where two independent outputs are driven by the same input signal.
How does a PhotoMOS work?
A PhotoMOS relay consists of a light emitting diode (LED), an array of solar cells with a control circuit and two Power MOSFETs. The LED on the input side of the relay starts emitting light when a drive signal is applied. With the help of the photovoltage from the solar cells, the Power MOSFET is operated.
What is OptoMOS relay?
IXYS Integrated Circuits CPC1010N OptoMOS® Relay is a 250V, 170mA single-pole normally open (1-Form-A) Solid State Relay which provides 1500Vrms of input to output isolation. The optically coupled output is LED-controlled while the MOSFET switches use IXYS Integrated Circuits’ patented OptoMOS technology.
What is photo MOSFET?
Photo-MOSFET relays are highly reliable, long life, and fast switching (AC or DC) solid-state relays. Also Photo-MOSFET relays switch voltages up to 1500 Volts and currents up to 4.5 Amps. Additional features include no contact bounce, low off-state leakage currents and stable on resistance.

How does a Panasonic photomos solid state relay work?
Panasonic offers Semiconductor relays in two types, Solid State Relays (SSR) and PhotoMOS Relays. The main difference between the two types can be found in the semiconductor device being used to switch the output: SSRs utilize Triacs and PhotoMOS relays employ two MOSFETs.
How are photomos different from conventional electro mechanical relays?
Obviously the PhotoMOS differ from the conventional electro-mechanical relays. PhotoMOS are classified to semiconductor relays that have no moving contact, therefore they are superior to conventional electro-mechanical relays in life-expectance and reliability of contacts, operation speed, and their sizes.
How are SSRs different from photomos relays?
The main difference between the two types can be found in the semiconductor device being used to switch the output: SSRs utilize Triacs and PhotoMOS relays employ two MOSFETs. PhotoMOS relays are used in telecommunication, measurement, security and industrial control.
How does charge and discharge control work on photomos?
1. Turn ON both solid state relays for charge and discharge control. Current flows in both directions. 2. In order to prevent over charging, the solid state relay on the charge control side turns OFF. On the discharge side, current will flow because there is a diode. 3.
