The PW4512 from Diotec Semiconductor is a high-performance, standard-recovery rectifier diode designed for demanding power applications. With a repetitive reverse voltage of 1200 V and a maximum average forward current of 45 A, the PW4512 delivers reliable performance in industrial and high-power environments.

Assembled in an industry-standard TO-247-2L package, the PW4512 ensures excellent thermal performance and easy heat sink assembly. The PW4512 features a low forward voltage drop of less than 1.1 V at 45 A and 25°C, which contributes to improved system efficiency and reduced power losses. The PW4512 also supports a high surge current capability of up to 300 A (10 ms), ensuring robust performance under transient conditions.

As such, the PW4512 is ideal for applications such as polarity protection or OR-ing circuits in battery-powered systems (e.g. back-up supplies for data servers or telecom base stations, UPS or solar water pumps), input rectification in industrial power supplies, motor drives, and inverters.
