MOSFET Output SSRs
MOS Output Solid State Relays (SSRs) are the most reliable, technically advanced logic-to-power interface devices available. Their basic function is to take a low current signal from a microprocessor to control the switching of both AC and DC loads, while providing an isolation barrier between logic and power.
Features
- Long life, fast and reliable switching
- Bounce-free switching
- Optical Input to Output isolation up to 5000Vrms (and beyond)
- Low Drive Current Options (<1mA)
Applications
- Telecom/Datacom switching
- Multiplexers
- Meter reading systems
- Data acquisition
AC Output SSRs
AC Output Solid State Relays (SSRs) provide an optically isolated means of switching AC Loads. Activated by the application of a logic level signal, these SCR-based devices tend to be more robust than their MOSFET Output counterparts, typically making them better suited to industrial switching applications wherein a load may connect directly to an AC Line.
Features
- High blocking voltage (up to 800 V)
- Switching AC loads without the generation of transients (ZVC devices)
- High Input to Output Isolation (5000Vrms)
- Long life / Bounce-free switching
- and more
Applications
- Programmable Control
- Valve control
- Solenoids and coils
- Remote switching
- Home appliances
- Metering equipment
- Heating Controls
- and more
MOSFET Drivers
Also referred to as MOSFET Gate Drivers or Gate Drive Optocouplers, SSO Photo-Voltaic MOSFET Drivers are an optically isolated means of driving discrete MOSFETs. Unlike conventional MOSFET Drivers, Photo-Voltaic MOSFET Drivers require no complex and costly external power supply circuitry to operate.
Features
- High input to output potential isolation (up to 5kVrms)
- No need for external power supply
- Solid State Reliability
- Input control current (2-20mA)
- Open Circuit Voltages (6-14V)
- Short Circuit Currents (3-25uA)
- and more
Applications
- MOSFET Driver
- Programmable Controls
- Process Controls
- Instrumentation
- Telecommunications
- Discrete SSRs
- Floating Power Source
Optocouplers
Optocouplers provide a means of optically isolated signal coupling. Whereas SSO's MOSFET and SCR Output SSRs provide integrated switching solutions, our broad line of optocouplers allow for flexibility where completely electronically isolated devices can be coupled discretely to a wide range of load handling components such as Power MOSFETs and Triacs.
Types
- Transistor Output Optocouplers
- Linear Optocouplers
- High Speed Optocouplers
- Schmitt-Trigger Optocouplers
Applications
- Office equipment including: Registers, Copiers, Fax Machines, and Laser Printers
- Home appliances, including; Microwave Ovens, Washers & Dryers, Refrigerator, Air conditioner, etc.
- and more
TRIAC Drivers
Also known as a Phototriac Coupler, a TRIAC Driver is a specific type of optocoupler that is used exclusively to provide an optically isolated gate drive current to a TRIAC. This allows designers greater flexibility in selecting the gate drive current and isolation value desired separately from the TRIAC required.
Features
- High input to output potential isolation (5 kVrms and beyond)
- Low input control current (as low as 2.5mA)
- Variable load voltages (400V to 800V)
- Random Phase and Zero Volt Switching
Applications
- Motor Control
- Motor Starters
- Dimmer Circuits (random phase devices)
- Solenoid/Valve controls
- Lighting controls
- Static power switches
- Temperature controls
- Solid State Relays
IGBT Drivers
IGBTs are commonly used in power electronic applications such as Uninterruptible Power Supplies (UPS), Solar inverters, Inductive heating, Motor Control, HF Welding and other PWM applications that require high switching speeds.
Features
- High Common Mode Rejection: 10 - 25kV/uS at VCM = 1500V
- Under Voltage Lockout Protection (UVLO) with Hysteresis
- Broad Temperature Performance Range (-40°C to 100°C)

Application Notes
In a MOSFET based relay, both AC and DC signals can be switched. The output utilizes two n-channel type MOSFETs. When controlling an AC load, one of the MOSFETs is used to switch the positive phase of the AC cycle while the other is used to switch the negative phase. When controlling a DC load, only one MOSFET is needed, and the relay can be configured to enhance switching characteristics.
