Electromechanical and semiconductor relays

CC series capacitor-coupled relay in the small TSON package

Low On-resistance, low output capacitance and low current consumption. Guaranteed performance at high temperature.

Ultra-miniature TSON package contributes to space-saving

These new capacitive-coupled TSON MOSFET relays belong to the successful Low CxR PhotoMOS® series. These relays have an optimized, very low product of C and R for the output transistors. In contrast to the well-known PhotoMOS® series, the galvanic isolation of the TSON relays between input and output is capacitive, not optical. This results not only in a much smaller design, but also offers considerable advantages in the temperature range, the drive power and the switching times. Thus, the new TSON relays can be operated up to +105°C ambient temperature. The current required for control purposes is typically low at 0.2mA, and the input can be operated directly with voltages of 3-5V typ. The series resistor as required by PhotoMOS solutions is therefore no longer necessary.
