Introduction

The SE30AFG-M3/6A is a single , surface- mountable, fast-recovery rectifier, specifically designed for high performance applications such as power supplies, DC-DC converters, motor control, LED lighting, and power conversion. It has a wide range of operating current, voltage and power capabilities and has been designed to meet the requirements of most modern electronics. This article will explain the SE30AFG-M3/6A’s application field, working principle, and main features.

Application Field

The SE30AFG-M3/6A is a single, surface- mountable, fast-recovery rectifier, specifically designed for high performance applications such as power supplies, DC-DC converters, motor control, LED lighting, and power conversion. It is also suitable for applications requiring low power dissipation, and high forward surge current capability. This device has been designed to meet the requirements of most modern electronics and is beneficial especially where the power density of a device that is cost effective with high efficiency and good EMI are required. Examples of such applications include AC/DC and DC/DC converters for off-line power supplies, converter-based motor control, LED lighting, and power conversions. The fast-recovery time also makes the SE30AFG-M3/6A highly suitable for other applications such as over-voltage protection circuits.

Working Principle

The SE30AFG-M3/6A rectifier works by allowing a forward current to flow when the anode voltage is greater than the cathode voltage. The forward current then drops once the voltage drops to a certain level, and the device goes into its fast recovery phase, during which time the leakage current is almost negligible. During this phase, the voltage on the anode side WILL steadily revert back to the same level as the cathode, however, the speed of this process depends on the capacitance of the device.

Features

The SE30AFG-M3/6A can provide a wide range of operating current, voltage, and power capabilities, making it suitable for a variety of applications. It offers an Avalanche capability and can withstand a repetitive avalanche current of up to 200mA. It has a maximum current rating of 33A at a junction temperature of 125°C, with a maximum forward voltage of 5.8V at 25°C, and a maximum reverse voltage of 5V. It has a peak forward surge current rating of 1A and can also withstand a reverse leakage current of up to 5μA at a reverse voltage of 5V. The device can operate over a wide temperature range from -55°C to 125°C meaning it is suitable for automotive, industrial, and commercial environments.Furthermore, the device also offers a low power dissipation, high forward surge current capability, and ease of assembly, meaning it is beneficial especially where high power density devices are required.
