The MDC3105DMT1G is an integrated relay and inductive load driver designed to replace multiple discrete components with a single surface-mount device in a compact SC-74 package. It is optimized for switching 3 to 6 Vdc inductive loads, including relays, solenoids, and small DC motors, without requiring an external free-wheeling diode due to its internal Zener clamp. The device can drive relay coils rated up to 2.5 W at 5.0 V and features low input drive current, ensuring efficient operation with minimal off-state leakage. This part is suitable for various applications, including telecommunications, consumer electronics, industrial systems, and automotive uses. It operates over a temperature range of -40¬8C to 85¬8C and is ESD resistant according to the Class 1C Human Body Model. The MDC3105DMT1G is Pb-free and halide-free, making it compliant with environmental regulations. Its low saturation voltage allows for the use of higher resistance relay coils, contributing to reduced system current drain.
