FR70KR05

FR70KR05 is a rectifier diode with a single package, mainly used in semiconductor rectifiers. As an ideal protection element for power components such as transformers, switches, inductors and busbars, the diode is more reliable, robust and cost-effective compared to other alternatives. The unidirectional current flow of the diode makes it particularly suited for voltage-sensitive applications.

The FR70KR05 offers efficient electrical insulation in a variety of applications. The forward current is specified at a maximum of 5A, at a peak repetitive reverse voltage of 1000V, making it suitable for applications including UPS, renewable energy sources, and rectifying radio frequency and high voltage AC. The device also offers surge tolerance of 1000V, and an operating temperature range of -40°C to +125°C.

Working Principle

The FR70KR05 is a single-directional, PN-junction diode. In essence, this means it only conducts in one direction, and will block current in the other direction. This makes it an ideal rectifier, allowing it to convert alternating current (AC) to direct current (DC). When exposed to a positive voltage, current can move from the anode to the cathode, creating a forward bias in the diode. When exposed to a negative voltage, current is blocked, creating a reverse bias in the diode.

The output voltage of the device is determined by the forward voltage drop. This occurs because the diode has a potential barrier in the form of an internal diode junction. This internal junction is only partially conductive and as a result, a voltage drop occurs when it conducts. This voltage drop is called the forward voltage drop, and typically varies between 0.7V (Silicon diodes) and 1.2V (Schottky diodes) depending on the type and construction of the diode.

Application Field

The robustness, efficiency and low voltage drop of the FR70KR05 makes it suitable for a range of applications. It is typically used in UPS systems, power supplies, renewable energy sources and rectifying radio frequency and high voltage AC. It can also be used protect components from over-voltage, as well as to control the current direction of a circuit.

The device can also be used to produce electrical isolation, as it allows signal to be transmitted from a signal source, to a load, without electricity flowing from one to another. This makes the FR70KR05 an ideal choice for applications such as telecommunications, signal transmission, and power line isolation.

Conclusion

The FR70KR05 is a single-directional, PN-junction diode, suitable for voltage-sensitive applications. Its unidirectional current flow, combined with its high surge tolerance, makes the device suitable for applications such as UPS systems, power supplies, renewable energy sources and rectifying radio frequency and high voltage AC. The FR70KR05 also offers efficient electrical isolation, making it ideal for signal transmission and power line isolation.
