Application Fields

The AU3PGHM3/87A can be used in a variety of applications, including power conditioning, LCD displays and LED lighting, automotive and industrial applications, and medical equipment. It can also be used for controlling the output voltage of power adaptors, providing efficient switch-mode rectification for automotive applications and reverse battery protection from large discharges. Additionally, it is suitable for the rectification of Li-Ion cell batteries.

Working Principle

The AU3PGHM3/87A is a high-speed, low-loss rectifier with a fast switch-mode operation, providing low switching and reverse recovery losses for power efficiency and suppressed EMI noise. The cutoff frequency of the device is at 8-12kHz, which allows the rectifier to switch frequencies faster than conventional diodes. Additionally, the turn-on time of the diode is reduced significantly compared to conventional diodes.

The device is constructed of silicon chips and p-n junction diodes, which provide a fast rectifying action with a free-wheeling diode to prevent voltage spikes. Its metal-oxide semiconductor (MOS) structure also helps to reduce noise and improve the operation of the diode. The AU3PGHM3/87A\'s low dissipation feature and current rating protect it from high temperature damage, and its reverse recovery time is typically less than 50 ns, making this rectifier suitable for high-speed applications.

The AU3PGHM3/87A is an ideal choice for power conversion applications as it is efficient, reliable and cost-effective. It is a highly reliable device that can provide high efficiency and low losses for a wide range of power conversion requirements.
