RB031B-40TL Datasheet/PDFDiodes - Rectifiers - Single
A single rectifier is a diode with a wide range of uses. The most common type of single rectifier is the RB031B-40TL. This diode is a fast-recovery, single phase, ultra low-loss, silicon rectifier.
RB031B-40TL Application Field
The RB031B-40TL is designed for ultra low-loss rectification in a range of applications, including power supplies, battery charging, motor controllers and uninterruptible power supplies (UPSs). It is also suitable for high-reliability telecommunication, light power switches and motor control systems, automotive and avionic applications.
RB031B-40TL Working Principle
The RB031B-40TL is designed to rectify an AC input into a DC output. This is done by the diode blocking the current flow in one direction, allowing it to flow in the other. The diode will only allow current to flow in the forward direction if the voltage difference between the anode and cathode is above its forward voltage drop, which is typically 0.7V for silicon diodes. The diode also has a reverse voltage tolerance, which is the maximum voltage the diode can withstand in the reverse direction without being damaged.
The RB031B-40TL has a maximum forward current rating of 40A and a reverse voltage tolerance of 600V, making it suitable for high powered applications. It also has an ultra-fast recovery time of just 25ns, making it suitable for high frequency applications, and a low junction temperature of -55°C to +150°C.
Conclusion
The RB031B-40TL is a fast-recovery, single phase, ultra low-loss silicon rectifier designed for a variety of applications. It has a maximum forward current rating of 40A, a reverse voltage tolerance of 600V, an ultra-fast recovery time of 25ns and a low junction temperature range of -55°C to +150°C. This makes it ideal for use in high-reliability telecommunications, light power switches, motor controllers, motor control systems, UPSs, automotive and avionic applications.
