Diodes, rectifiers, and arrays are essential components used in almost every electrical circuit. STPS41L30CG-TR is a popular rectifier array semiconductor produced by ST Microelectronics. This versatile device is commonly used by circuit engineers and technicians in a huge variety of applications. This article will provide an overview of the versatile STPS41L30CG-TR and discuss its general application fields as well as its working principle.

What is STPS41L30CG-TR?

The STPS41L30CG-TR is a quad, low-power Schottky barrier rectifier (SB) array consisting of 4 individual 30 V, 0.25 A rectifier diodes. The STPS41L30CG-TR includes a built-in stress-limiting resistor, which allows it to achieve higher efficiency performance without sacrificing power dissipation. It also has reverse leakage current of less than 0.1 μA and is rated for operation up to 150°C junction temperature.

Application Field & Working Principle

The STPS41L30CG-TR is suitable for a wide variety of applications, including general-purpose power rectification, DC-DC converters in various battery-powered applications, load shared ripple current protection and voltage regulation, and solar power conversion. The device is also suitable for automotive applications and is protected against excess current due to its built-in, stress-limiting resistor.

The working principle of the STPS41L30CG-TR is relatively simple. It is basically an array of four independent Schottky diodes connected in series. When a voltage is applied to the device, a current flows through the four diodes in the device. When the voltage reaches Vmax (Vmax being equal to the reverse breakdown voltage of the diodes), the current increases quickly. This “saturating” current is limited by the built-in stress-limiting resistor, which allows the device to operate in a more efficient manner while still providing effective current limiting protection.

The STPS41L30CG-TR can also be used in reverse-biased applications, such as low-power voltage-regulation solutions or to protect against reverse voltages from battery-powered applications. The device is capable of operating at high-temperature dielectric and humidity conditions, making it ideal for automotive applications. It also has a low forward voltage drop and can be used for applications with large ripple currents.

Advantages of the STPS41L30CG-TR

The STPS41L30CG-TR offers several advantages over conventional Schottky diodes. The quad-array configuration enables it to achieve higher power dissipation than conventional Schottky diodes with the same reverse breakdown voltage. The device also has reverse leakage current of less than 0.1 μA, and it is rated for operation up to 150°C junction temperature.

The built-in, stress-limiting resistor on the device allows it to operate in a more efficient manner, which in turn reduces power consumption and increases reliability. The overall efficiency of the device is improved due to the lower forward voltage drop, which enables it to regulate voltage more accurately and reduces power loss from the device.

The STPS41L30CG-TR is also suitable for larger ripple protection applications, due to its low forward voltage drop and high current capacity. The device is suitable for operation even at high-temperature dielectric conditions, allowing it to be used in automotive applications, as well as other high-temperature applications.

Conclusion

In conclusion, the STPS41L30CG-TR is a versatile rectifier array that offers a wide variety of applications. It is suitable for a wide range of applications, including general-purpose power rectification, DC-DC converters in various battery-powered applications, load shared ripple current protection and voltage regulation, and solar power conversion. Moreover, its low forward voltage drop and high current capacity make it suitable for use in larger applications. The device also has low reverse leakage current and is rated for operation at high-temperature dielectric conditions, making it suitable for automotive applications.
