SR2090PTHC0G

SR2090PTHC0G diodes from Vishay Semiconductor are members of their popular SR alloy diode series. These diodes are array-type, high speed rectifiers. The diodes are rated up to 1000 V and can handle continuous current up to 8.0 A. Unlike regular diodes, these are ideal for smoothing the output power of motor drives, AC to DC power supplies, and DC to DC converters. Thanks to their high current capacity and fast switching speed, these diodes can also be used as active clamping diodes in active EMC filters. The diodes are halogen-free, conform to RoHS directives, and have UL certification.

Package

SR2090PTHC0G diodes are constructed in a D2Pak, 6-pin package. This is a medium-sized surface mount package. It has two leads to the left of the diode and four to the right. Two lead pairs are mounted on the same side of the diode body. The two pins to the left of the diode can separated from the four pins to the right of the diode. The body size is of 17.3x20x4.6mm.

Application Field

SR2090PTHC0G diodes are excellent for applications where fast switching speed, high-current handling, and tight temperature control are needed. These components are most useful in AC to DC or DC to DC converters. In particular, they can help make the output voltage and current of the converter more stable and reliable. These diodes are often used in uncontrolled rectifier applications, switching mode power supplies, and motor drives, as well as active EMC filters for suppressing high frequency noise.

Working Principle

SR2090PTHC0G diodes are constructed of Schottky barrier type diodes. They have an abrupt turn-on characteristic and low turn-on voltage. The low forward voltage and high switching speeds of these diodes allow them to be used in high frequency applications. The forward voltage drop of these diodes is the same regardless of the forward current, so they can be used in applications without any surge current or power loss. The diodes also have high temperature stability, allowing them to be used in applications which require a long life of operation.

Conclusion

SR2090PTHC0G diodes from Vishay Semiconductor are ideal for demanding AC to DC or DC to DC converters and EMC filter applications. The fast switching speed and high current handling of these components make them highly suitable for active clamping diodes. The diodes are constructed of Schottky barrier type and low turn-on voltage, making them excellent for high frequency applications. The forward voltage drop of these diodes is constant over a range of forward current, ensuring reliable operation in uncontrolled rectifier applications.
