MOS FET Relays Technical Information Introduction New models with a wider range of characteristics provide an array of The built-in Current Limit Function (CLR models) has many uses. solutions, meeting the needs of todays high performance applications. Traditionally used to clamp excessive over current fault conditions in telecom equipment, this feature can also be used to good effect to Our expanded range of MOS FET relays, Type G3VM, sets the resist transient and short circuit conditions. benchmark in Solid State Relays (SSRs). Products are manufactured using the latest advances in automated production and include a MOS FET relays are the ideal data and telecommunication solution variety of improved construction technologies within the areas of the for line seizing, line switching, hook switching, Data Access Arrange- input LED, PDA (Photo Diode Array used as a photocoupler) and ment (DAA) function, line transformer circuit control and other feature MOS FET chips used in the load switching circuit. As a result, further phone functions. Central office applications require high reliability reductions in package size and power requirements have been and long life.

Load WARNING Do not touch the charged terminals of the SSR, otherwise an elec- tric shock may be received. CAUTION Do not apply overvoltage or overcurrent to the I/O circuits of the SSR, otherwise the SSR may malfunction or burn. CAUTION Be sure to wire and solder the Relay under the proper soldering Transistor conditions, otherwise the Relay in operation may generate exces- sive heat and the Relay may burn. 10 to 100 k Load CAUTION Electrostatic sensitive devices.
