ON Semiconductor MCR68-002 Thyristor SCR

The MCR68-002 from ON Semiconductor is a high-performance silicon-controlled rectifier (SCR) designed for phase control applications in converters, power control systems, and motor control circuits. This SCR is a robust and reliable semiconductor device that can switch and control high-power AC or DC currents effectively.

The MCR68-002 is characterized by its high surge capabilities and low on-state voltage drop, making it an efficient choice for applications requiring frequent switching and high current handling. It is capable of handling a repetitive peak off-state voltage (VDRM) of 600V and a non-repetitive peak off-state voltage (VDSM) of 700V, ensuring stability and protection against voltage transients.

With a maximum average on-state current (IT(AV)) of 8A, the MCR68-002 can manage considerable power levels, and its surge current rating (ITSM) of 80A at 60Hz signifies its ability to handle high current peaks without failure. This SCR also features a low gate trigger current (IGT), making it easy to drive and control with simple gate drive circuits.

The device is housed in a TO-220AB package, a compact and widely used package that facilitates easy mounting on printed circuit boards (PCBs) and offers excellent thermal performance. Its operating junction temperature range is from -40°C to +110°C, which allows for reliable operation in a wide range of environmental conditions.

Applications for the MCR68-002 are diverse and include motor control for industrial machines, lighting dimmers, controlled rectifier bridges, and soft start circuits where gradual voltage ramp-up is necessary. Due to its robustness and high current capability, it is also suitable for use in overvoltage crowbar protection circuits.

ON Semiconductor's commitment to quality ensures that the MCR68-002 meets stringent standards, making it a trustworthy component for designers and engineers looking to build efficient and durable power control systems.
