53262

53262 SOLID STATE RELAY, 400VDC- 0.5A OPTICALLY ISOLATED, SHORT CIRCUIT PROTECTED Mii MICROCIRCUITS DIVISION Features: SPST, Normally Open 1000VDC Optical Isolated Control Input Power MOSFET, Low On-state Resistance Built-in Short Circuit Protection Wide Operating Temperature Range Non-hermetic Package DESCRIPTION Applications: COTS Military Applications Gun Turret Controls Motor or Solenoid Driver Displays/Lamps/Controls Industrial Automation 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 usi...
