Series SR75-1: 1.5 Amp 300 Vdc Plastic SMT, THT, Short Circuit Protection
The SR75-1 solid state relay utilizes a power FET switch that is protected against short circuit and overload currents. The short circuit protection feature not only provides protection should a short or overload occur while the relay is on, but will also provide protection should the relay be switched into a short. In either case, the relay will sense the short circuit condition and then block it indefinitely until the short is removed and the unit is reset by cycling the input control. Using the SR75-1 to switch power sources and loads can prevent fires, damage to system assemblies and system wiring. The power FET output offers low ON resistance and can switch loads in either the high or the low side of the power line. The SR75- 1 is packaged in a 16 pin DIP package with either surface mount or through hole mounting available.
