MURH10060R Application Field and Working Principle

The MURH10060R is part of the MURH10060 family of ultrafast rectifiers from Diodes Incorporation. It is designed for use in automotive electronic systems and has a range of beneficial features for such applications, including low forward voltage drop, increased efficiency and good surge handling capability.

This rectifier is a single-phase, full bridge rectifier with a fast recovery time of 15ns. The maximum forward current rating is 6A, and the reverse voltage rating is 1000V. The operating temperature range is -40C to 175C. It is also designed to comply with the AEC-Q101 automotive quality standard.

The MURH10060R is fabricated using a planar process to ensure superior reliability and repeatability over the full temperature range. It is composed of an internal high-speed Silicon Carbide (SiC) junction on an insulation layer and an ultra-short reverse recovery time to reduce switching losses. It also uses an 82mΩ internal bias resistor to reduce device power dissipation.

In operation, the device is connected across an AC power line. When one diode conducts, a forward voltage is created. This voltage is blocked by the other diode so that it can only flow through the conducting diode. When the voltage reaches its peak, the other diode, which is in a reverse-biased state, becomes forward-biased, and the current conducting diode is then reversed. This process is repeated across the AC supply line, thus allowing the rectified voltage to be applied to the load.

The MURH10060R has higher forward voltage and lower reverse voltage than other rectifiers in its class, allowing for increased efficiency. Additionally, its fast recovery time decreases the EMI noise that can be generated in high-frequency switching applications. It also has a high surge current capability and a low device impedance, making it suitable for use in harsh automotive environments.

In summary, the MURH10060R is an ideal device for automotive applications, providing superior reliability, efficiency, and surge current capability. Its fast recovery time and low device impedance allow it to comply with stringent automotive standards, while its low forward voltage drop and low reverse voltage allow it to reduce power losses and improve system performance.
