Introduction

The STTH120L04TV1 is a rectifier array package from STMicroelectronics which provides the user with an efficient, cost-effective and reliable solution for power conversion from AC to DC. The STTH120L04TV1 rectifier array uses two series connected in parallel pairs to produce a four-phase half wave rectifier. This array also includes a direct coupled voltage doubler topology. This configuration delivers improved speed and efficiency due to the parallel pairs minimizing conduction losses and the voltage doubler providing increased voltage transfer efficiency.

Package & Pinout

The STTH120L04TV1 is an 8-pin device packaged in a TO-220 plastic package and featuring 4 discrete p-type MOSFETs. The pinout of the STTH120L04TV1 is as follows:Pin 1: SourcePin 2: V_CSPin 3: Drain1Pin 4: V_DS1Pin 5: Drain2Pin 6: V_DS2Pin 7: Drain3Pin 8: V_DS3

Application Field

The STTH120L04TV1 is used in numerous high-power applications, ranging from DC-DC converters to uninterruptible power supplies (UPS) and motor control applications. Due to its fast switching speeds and high efficiency, it can also be used in high power switching regulators and power amplifiers. It has also been used in various automotive and industrial applications.

Working Principle

The STTH120L04TV1 works by using two series connected in parallel pairs to produce a four-phase half wave rectification. This produces a full wave rectified voltage output, greatly increasing conversion efficiency. Additionally, the direct coupled voltage doubler topology allows for improved speed and greater efficiency.When a supply voltage is applied across the rectifier array, the gate of each MOSFET is driven by a charging circuit, causing current to flow through the body diode. As the voltage increases, MOSFET 1 begins to conduct and current is supplied to the load. At the same time, current is also supplied to the other two channels, but due to the opposing body diode direction, negative current is supplied to the load, allowing the current to be transferred in both directions. This feature allows for full wave rectification, where both positive and negative currents are supplied to the load, thus producing an efficient output voltage.

Conclusion

The STTH120L04TV1 is a cost-effective and reliable package made for high power applications which require fast switching and high efficiency. Its full wave rectification process produces an efficient output voltage and its direct coupled voltage doubler topology provides improved performance and higher efficiency. Additionally, the 8-pin TO-220 package makes it relatively easy to use in tight spaces.
