The STTH30RQ06G-TR is a very common fast-recovery diode rectification made by ST Microelectronics. It is a single package device rated for 600V, 30A designed using their patented SuperTrench technology. This technology provides a more efficient heat transfer and reduces losses to deliver higher efficiency and more power density for consumption in automotive applications. In general, rectifiers are highly specialized power electronics devices that are used to convert AC into pulsed DC current.

Application Field

This STTH30RQ06G-TR rectifier is a popular choice for automotive, industrial and commercial applications. It is frequently used in engines, alternators and other electronic circuits where stable DC is needed. It is also an ideal choice for automotive starters, alternators and other circuits where high reliability and low noise are critical.

The STTH30RQ06G-TR is also commonly used in defibrillator applications, due to its fast response time, low forward voltage and low noise characteristics. Other possible applications include, solar panel inverters, battery chargers and AC switchers.

Working Principle

A rectifier is a device that converts AC voltage into DC voltage. The AC voltage is converted into pulsed DC current. The STTH30RQ06G-TR rectifier is a two-part device consisting of the forward biased Schottky diode, and the anti-parallel Schottky diode, which reverse biases when the voltage reaches the peak. This ensures efficient energy transfer.

When an AC voltage is provided, the AC is first rectified, which means that the voltages of both positive and negative polarity are reduced to only one type (direct current). This is done by creating a circuit with the positive part of the AC voltage connected to the anode of the Schottky diode, while the negative portion is connected to the cathode. The forward biased Schottky diode is then used to allow only one kind of voltage to pass, the positive portion.

When the peak voltage is reached, the anti-parallel Schottky diode reverses bias, resulting in the current flowing through the diode in the opposite direction. This current is eventually eliminated when the negative portion of the AC voltage passes, due to the process of reverse recovery. The rectified voltage travels along the load network, providing DC power.

Rectifiers play an important role in both commercial and industrial applications, due to their ability to convert AC power into DC power. The STTH30RQ06G-TR is a popular choice for rectifiers. With its fast response time, low forward voltage and low noise characteristics, this device is ideal for a wide variety of applications.
