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.
