The STPS30M80CT is categorized as a product under the Diodes-Rectifiers-Arrays series, which consists of rectifying semiconductors of superior reliability. This product series is used in electronic applications such as motor control, power supply and motor drive. The STPS30M80CT can do so by providing low resistance values in the on and off state for improved power dissipation and fast switching.

Application Field

The STPS30M80CT is specifically designed for high current applications. As an automotive grade thyristor, the product is an ideal choice for automotive and high current applications thanks to its functionality and optimized design. The product is best suited for automotive and industrial applications as it is resistant to shock and vibration. In addition, it is AEC-Q101 qualified, which means it has gone through rigorous automotive testing and is certified for use in harsh automotive environments.

Working Principle

The STPS30M80CT device works on the principle of a thyristor. It includes an anode (A), cathode (K) and gate (G) terminal. When a positive voltage is applied between the anode and the gate terminal, the device enters the "on-state" and will conduct. If a negative voltage is applied between the gate and anode, then the device will transition to the "off-state" and be reverse biased, thus making it non-conductive.

The product is then designed and built for high current applications due to its superior junction temperature and avalanche capability. This allows for the on-state resistance to be kept lower than normal, improving power dissipation without compromising the fast switching performance.

In addition, the STPS30M80CT is designed for safety, which assures that the device is used in an environment where no risks of electrical mishaps exist. The product features a self-protected structure and a built-in temperature sensor that allows for self-protecting measures. This temperature sensor is capable of disconnecting the device when it reaches a certain temperature, effectively limiting power losses.

The STPS30M80CT also includes a unique feature called over-temperature protection, which is designed to protect the device from overheating in high current applications. This feature ensures that the device remains at a safe operating temperature, improving its reliability and life expectancy.
