Reverse conducting thyristor for two-wheeled motor vehicle regulators (Renesas Technology)

Renesas Technology Co., Ltd. (hereinafter referred to as Renesas) announced the launch of the CRD5CM reverse-conducting thyristor for two-wheeled automotive voltage regulators and general-purpose batteries. The CRD5CM integrates thyristors and rectifier diodes in a single component. The product will be available for sale in February 2010.

The CRD5CM is mainly aimed at two-wheeled vehicles with strong demand in small size and low price. Such vehicles currently continue to grow in markets such as China, India and Indonesia. The main features of CRD5CM are as follows:

(1) The industry's first reverse-conducting thyristor in a small package for two-wheeled motor vehicle regulators In addition to the industry's first reverse-conducting thyristor for two-wheeled automotive regulators, the CRD5CM's TO-220 package is also compatible with Sa's previous thyristor (cell) products used the same package. This means that the mounting area can be reduced by approximately 50%, thereby reducing component mounting costs and enabling the design of smaller, more economical regulators.

(2) The thyristor with rated current of 5A and rated voltage of 400V realizes single and small package. The thyristor utilizes Renesas' advanced planar structure to achieve 5A rated current, 400V rated voltage and 80A (50Hz). Inrush current. In this way, it can handle the inrush current generated during the switching process.

(3) Diodes with 5A rated current and soft-off characteristics Single- and small-package diodes utilize Renesas' advanced planar structure to achieve 5A rated current and 80A (50Hz) surge current.

In addition, two-wheeled motor vehicle regulators require a Rectifier Diode with soft reverse recovery characteristics. The CRD5CM's diodes feature a soft-shutdown feature with a reverse recovery time of 4.0μs (typ), which limits the voltage surge generated during commutation commutation.

The CRD5CM in the TO-220 package has a thermal resistance of 2.8°C/W and an operating temperature of up to 150°C, allowing the use of smaller cooling fans in the system.
