SDURD520TR Discrete Semiconductor Products

Diodes - Rectifiers - Single

The SDURD520TR is a Fast Recovery Diode from NXP Semiconductors. It is designed for use in high-frequency power conversion. Its features include a low forward voltage drop, high forward conducting current, and a fast recovery time for improved power conversion efficiency.

The SDURD520TR is typically used in high-frequency DC-DC conversion circuits in applications such as telecom power supplies, computers, consumer electronics and automotive applications. It can be used in bridgeless AC to DC converters, flyback converters, forward converters, DC to DC converters, resonant half bridge converters, full bridge converters, as well as drivers for half bridge converters. Other applications include high-frequency switching applications, where it is used as a protection device to limit bus voltage transients.

The SDURD520TR features a low forward voltage drop, a maximum trr, a low thermal resistance, and an improved reverse leakage current for superior power conversion efficiency. The forward voltage drop is typically 0.53V at a forward conduction current 0.5A, and the maximum trr is 20nS. The reverse recover time is reduced, further improving the efficiency of power conversion.

To ensure superior performance, the SDURD520TR has a built-in temperature derating and over-current protection. It also features a low internal capacitance which reduces the ringing effect and capacitive loading during high-frequency switching. For improved system reliability and availability, the device is RoHS-compliant.

The SDURD520TR is constructed using a molded leadframe with a glass-epoxy package body to improve reliability and thermal performance. The device is rated for operating temperatures from -55°C to 125°C. To reduce the effects of noise interference, the device has a built-in EMI shield.

The SDURD520TR is an efficient and reliable rectifier and is suitable for use in high-frequency dc-dc conversion circuits. With its low forward voltage drop, fast recovery time, and built-in protection measures, it is well suited for a wide range of applications in the telecom, computing, and automotive industries.
