Solid State Relays — Introduction
Solid State Relays (SSRs) are semiconductor-based switching
devices that operate optically rather than mechanically.
They incorporate three major components: A GaAs LED on the
input side, a photovoltaic diode array, and a FET switch on the
output side. Renesas Solid State Relays are available in a standard
Normally Open configuration:
FORM A “Normally Open”
In a FORM A relay, when no input current is present, the FET
switch on the output side is nonconductive, or “open.” When
current is applied, the LED lights and the photovoltaic diode array
responds by producing a voltage that ’s applied to the gates of the
FET. When the gates’ voltage threshold is reached the FET switch
becomes conductive - or closes - effectively switching the relay’s
load. When the current is removed, the light stops and blocking
diodes prevent charge from leaving the gates of the FET.
As voltage from the photovoltaic array is reduced across the
blocking diodes, it reaches a level that triggers a thyristor. The
charge is then quickly removed from the gates and the FET goes
nonconductive — returning the relay to its Normally Open state.
Why switch from Electro-Mechanical Relays (EMRs) to Solid State Relays?
? No moving parts
? High resistance to shock and vibration
? No arcing or contact bounce
? No Cross Talk
? Extremely fast
? Will switch AC or DC, output conduction is
unrelated to input current levels
? Stable R ON over the life of the device
? Proven reliability: 150X better than EMRs

CEL offers a wide variety of Renesas SSRs for a broad range of
applications: These include low CxR devices for high frequency
signal control, low RON devices for high current control, and devices
designed specifically to handle high voltages. SSR input logic is
compatible with a variety of control schemes and can be driven
directly by low voltage microcontrollers. With Renesas’s broad product
offering, it ’s easy to find an SSR that meets your specific needs.
Applications:
? Telecom/Datacom
? Test & Measurement
? Programmable Logic Control
? Instrumentation
? Power Switching
? Motor Drive Interfaces
