Diodes are semiconductor devices that act as a one-way street to current flow. Rectifiers are diodes that serve the purpose of converting alternating current (AC) to direct current (DC). Single rectifiers are used when only half of an AC source needs to be converted to DC. The S5M-M3/9AT application field and working principle is an efficient single rectifier option for power applications in markets such as telecoms, lighting, computing, and automotive.

S5M-M3/9AT touts its low voltage and current losses as two major advantages for customers. The S5M-M3/9AT works at a current rating of 9A and a voltage rating up to 400V, meaning it is ideal for applications where the goal is to convert AC current form low and mid-voltage sources (230- 400V). The S5M-M3/9AT has an average forward voltage drop (VF) of 1.5V @ 8.3A and maximum reverse leakage current (IR) of 100uA @ 400V. Its ultra-low VF, combined with its fast switching time, makes it suitable for high-frequency applications.

The S5M-M3/9AT design is based on a compound arrangement of two Schottky rectifiers and two high voltage Schottky barriers. This arrangement has a unique performance profile, allowing S5M-M3/9AT to provide full-wave rectification with a low saturation voltage across different operating temperature range of - 40°C to +125°C. The device has a low forward voltage drop of only 1.5V @ 8.3A and a reverse leakage current of 100uA @ 400V. This feature allows the S5M-M3/9AT to work efficiently even in harsh environments.

The S5M-M3/9AT also has an ultra-low reverse recovery time (RR), which is a measure of the time it takes for a device to transition from reverse-biased to forward-biased. This is especially useful for switching power supplies and other high-frequency applications. The S5M-M3/9AT manages to achieve a RR of just 2ns, meaning that the transition between forward and reverse bias occurs very quickly, allowing for improved operation efficiency and reliability. Additionally, the low saturation voltage improves EMC performance, increasing the overall life of the system.

The S5M-M3/9AT offers robust performance for cost-sensitive applications. It has an integrated PRC (Polymer Resin Thin-film Capacitor) to rapidly store energy and increase efficiency during fast-transition switching cycles. Additionally, it is designed with its standard flat face, which allows for easy smd soldering and fits in a standard 8-pin package. This package is compatible with PC board layouts and has a self-bonding capability that eliminates the need for manual soldering.

In conclusion, S5M-M3/9AT is an ideal single rectifier option that can be used in power applications in the telecoms, lighting, computing, and automotive markets. It offers low voltage and current losses, as well as fast switching time, ultra-low forward voltage drop, and an ultra-low reverse recovery time, all of which are essential for efficient and reliable power control. Additionally, its low saturation voltage and integrated PRC offer improved efficiency, higher quality systems, and longer system life.
