Diodes - Rectifiers - Single

The RSX101MM-30TR is a single-phase, silicon rectifier manufactured by Ixys Corporation. It is a versatile, semi-controlled rectifier used in a variety of applications, from high-current AC-to-DC voltage rectification to polarity protection for DC or AC circuits. This diode is capable of delivering highest surge current ratings of up to 3,000 Amperes and maximum surge power up to 180W; making it an ideal choice for applications where high peak performance is necessary.

Application Field

The RSX101MM-30TR is a versatile rectifier suitable for many different applications. The device is well-suited for use in high-current AC-to-DC voltage rectification systems, where it can replace costly diodes such as those found in many motor control systems. The diode is also suitable for use as a polarity protection device in both DC and AC circuits, as its fast recovery time allows it to effectively quench currents. Thanks to its high surge ratings, the RSX101MM-30TR is also an ideal choice for applications requiring high peak current and peak power performance, such as DC welding systems or other low-frequency power conversion systems.

Working Principle

The RSX101MM-30TR is a semi-controlled, high-performance rectifier designed to convert alternating current (AC) to direct current (DC), or to protect a circuit from reverse polarity. The device contains four rectifying diodes connected in pairs, each with a variation of a semi-controlled diode. This allows the device to rectify voltage more quickly than conventional, uncontrolled diodes. The four diodes are connected in a bridge configuration, with each individual diode and its cathode linked to the anode of the other.

When the voltage across the device is positive, the anode of each diode is approximately 0.7v higher than the cathode. This causes an electric current to flow from the anode to the cathode, allowing the AC voltage to be converted to a DC voltage. When the voltage across the device is negative, the reverse biased diodes prevent a current from flowing. In this way, the device is able to protect circuits from reverse polarity.

The RSX101MM-30TR is capable of withstanding high surge ratings thanks to its fast recovery time. This allows the device to effectively quench high currents and protect the circuit from damage. Due to its versatility and high performance, the RSX101MM-30TR is a suitable choice for many different applications, making it a popular choice for designers in need of a reliable rectifier solution.
