Diodes - Rectifiers - Single

The 1N5402-TP is a fast-recovery diode, also known as a freewheeling diode. It is a type of diode specifically designed to reduce power losses in switching power supplies such as AC-DC converters and DC-DC converters. By safely conducting the current after the power switch has turned off, it enables the power supply to be more efficient and reliable.

Application Field

The 1N5402-TP is specifically designed for applications in high-power switching power supplies. It can be used in a variety of converter topologies and applications, including AC-DC and DC-DC converters, voltage-mode converters and buck/boost converters. It can also be used in legacy power supplies and offline conversion applications.

The 1N5402-TP is especially well suited for use in automotive applications, such as motor control and battery management systems. It is also used in motion control applications, such as motor drives and inverters, as well as in industrial power supplies, renewable energy technologies and lighting solutions. Additionally, it is used in telecom and networking, medical devices, and other high-reliability applications.

Working Principle

The 1N5402-TP operates based on the principle of a solid-state switch. When power is applied to the 1N5402-TP, it acts as a open-switch, allowing a flow of current from anode to cathode. During this period, the diode limits voltage to a safe level. When power is removed, the diode acts as a closed-switch, preventing current from continuing to flow. This is known as the recirculation process, and it helps ensure that the power supply is efficient and reliable.

The 1N5402-TP also offers superior over-temperature protection, as it is designed to shut down when the temperature exceeds a certain level. This safety feature helps prevent catastrophic failures in high-power applications. Additionally, the 1N5402-TP features a reverse-recovery time of less than 1 µs, which enables it to switch at very high frequency.

The 1N5402-TP features a wide operating temperature range, from -40°C to 125°C. This makes it well suited for use in automotive and industrial applications, as well as for use in harsh environments. It is also RoHS compliant and UL approved, making it suitable for use in consumer applications.

Conclusion

The 1N5402-TP fast-recovery diode is a reliable and versatile semiconductor device, specifically designed for use in high-power switching power supplies. It offers superior performance, excellent temperature protection, and a wide operating range, making it ideal for a variety of applications, including automotive, industrial, telecom and networking, medical, and consumer applications.
