The S70KR rectifier diode is a general-purpose device used in switch-mode power supplies, DC-DC converters, UPS systems, and other similar applications. It is designed to provide efficient, high-speed switching, while at the same time reducing voltage losses. This diode is especially useful in applications that require high switching speed, low voltage drop, and high current capacity.

The S70KR feature A wide operating temperature range, high voltage rating, Low Forward Voltage Drop (VF) and high blocking voltage. In addition, its small surface-mount package is designed to provide reliable operation in high-temperature, high-voltage environments. The low VF and high blocking voltage help to reduce switching losses and extend the life of the device.

The S70KR has an operating frequency range of 20 kHz to 2 MHz, with a peak forward current of up to 60A and a peak reverse voltage of 600V. The reverse recovery time of this diode is typically less than 50ns, enabling fast switching applications. It is also capable of handling both continuous DC and transient AC currents, making it suitable for automotive, industrial, and medical applications.

The working principle of the S70KR is based on the p-n junction. When a forward biasing voltage is applied, electrons from the negative side of the junction move to the positive side, creating a p-n junction. This creates a low-resistance channel that allows current to flow from the anode to the cathode. When a reverse biasing voltage is applied, the channel is de-activated, causing the diode to act as an open circuit.

The S70KR provides fast switching capability and low voltage losses, making it ideal for applications where fast switching speed, low voltage drop and high current are required. It is especially useful in switch-mode power supplies, UPS systems, and other similar applications. It is also highly suitable for automotive, industrial and medical applications due to its wide operating temperature range and its ability to handle both continuous DC and transient AC currents.
