The STPS30L120CT is a current-controlled power switch DPAK (TO-252) package which enables efficient, low-loss power delivery in a variety of applications, such as switched-mode power supplies (SMPS). This diode-rectifier array houses two dual complementary P-channel MOSFETs in a single package, ensuring safe and reliable power delivery in a compact, space-saving form factor.

Application Field

The STPS30L120CT is designed for use in many different applications, such as general power management, high-density power modules, and other applications using efficient, low-loss power delivery. This diode-rectifier array can be used for SMPS applications where low conduction or switching losses are required, such as motor control and automotive applications. The STPS30L120CT also offers reliable operation and efficient power delivery in DC/DC converters.

The STPS30L120CT is also suitable for use in high-density synchronous rectification and resonant half-bridge designs. It offers a low RDS(on) on the two complementary channels for a small double-pulse charge discharge and free-wheeling current drive to reduce conduction losses. This makes the STPS30L120CT suitable for applications with highly efficient power delivery.

Working Principle

The STPS30L120CT diode-rectifier array contains two MOSFETs that operate in complementary synchronous rectification. This arrangement helps to reduce conduction losses and to provide efficient power delivery. This diode-rectifier array has two internal drives to provide better control of the on-state resistance. It also has over temperature protection and integrated gate-driving functions to control the MOSFETs.

The STPS30L120CT works by utilizing two independent voltage levels. The MOSFETs turn on when the voltage is greater than a certain threshold, and turn off when the voltage is less than a certain threshold. The two MOSFETs are connected in series, so when one turns on, the other turns off, and vice-versa. This ensures that a free-wheeling current is enabled for high efficiency.

The STPS30L120CT also contains an integrated gate drive circuit that can provide better control of the on-state resistance. This gate drive circuit also has over temperature protection and shutdown functions to protect the MOSFETs from damage. It also contains an under-voltage lockout circuit to prevent the MOSFETs from turning on until the supply voltage has risen to a certain level.

The STPS30L120CT is a highly efficient and reliable power switch which can be used in a variety of applications for efficient power delivery. This diode-rectifier array has all of the features that are necessary for reliable and efficient power delivery in a variety of applications.
