DESCRIPTION

The 53262 Solid State Relay (SSR) is designed for applications in environment where hermeticity is not required. Its solid
state “contact” is resistant to damage from shock and vibration. It is also immune to contact related problems
(contamination, arcing, bouncing, etc.) associated with the electromechanical relays. Functionally, the device operates as
a single-pole single-throw (SPST), normally open (1 Form A) unidirectional high-side or low-side switch. Using a 500VDC
rated N-channel MOSFET as the switching device, the 53262 SSR offers low on-state resistance for lowering the power
dissipation, which allows operation over the temperature range of –40°C to +85°C with minimal heat sinking. A built-in
current sense circuit offers short circuit protection by turning off the MOSFET switch and allowing no current flow into the
load. After the 53262 SSR tripped due to a short circuit load, the output latches in the off-state until its control input
recycles. The control input is isolated from the load circuit using an optocoupler. This isolation barrier will eliminate the
system ground loop noise of the application. The optocoupler employs a dual high efficiency LED input allowing
TTL/CMOS logic to drive the solid state relay. The SSR is actuated by applying an input forward current of 5 to 10 mA to
the LED’s. The 53262 SSR has no moving parts and is enclosed in a non-hermetic package.

4. The minimum over-current limit occurs at Tc of 85°C. The maximum over-current limit occurs at Tc of -40°C.

5. Use 0.25 ohm sense resistor for monitoring the peak short circuit current.

6. The user should apply the appropriate transient suppression technique to the output terminals of the relay when
the loads are inductive enough to generate voltage spikes.
