53012 SPST SOLID-STATE RELAY Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: Replacement for M90FS-2 SPST, Normally Open Integral Short Circuit Protection Power FET Output Low On-state Resistance Full Military Temperature Operation: -55ºC to +125ºC Military Environmental Screening Available Improved Thermal Characteristics Built in accordance with 85006-001 Applications: Low Level Power Control Current Loop Switches Isolated Line Driver Selection Servo and Synchro Resolver Control Military/Aerospace General Purpose Switching DESCRIPTION The 53012 is a military SPST solid-state relay. This light-weight device is resistant to damage from shock and vibration, and is immune to contact-related problems (contamination, arcing) associated with mechanical equivalents. Optical coupling between the input and output stages provides effective isolation up to 1000 volts AC RMS. Power FET outputs eliminate bipolar offset, and minimize output voltage drop. The control logic is TTL compatible, and will accommodate bias supplies between 3.8 and 32 VDC. Integral short-circuit protection is provided in the 53012. This unit senses excessive current flow while under load or while switching, and respond by opening the output. The output will remain blocked indefinitely until the short is removed, and the unit reset. This feature prevents damage to the unit, and also averts further system failures that may be caused by the shortcircuit. Resetting the unit can b...
