Transient voltage suppressors (TVS) are widely used for transient protection of electronic equipment due to their ability to absorb large amounts of electricity without any significant damage. The DFLT27A-7 is a Transient Voltage Suppressor Diode designed for high performance, bidirectional protection against overvoltage transients.

The DFLT27A-7 is housed in an SOD-123FL package composed of a low-profile proprietary material and a lead frame. This package, which is compliant with JEDEC standards, is ideal for applications in high-efficiency power supplies, power delivery networks, and data communication systems.

Application Field

The DFLT27A-7 offers outstanding electrical performance with minimal size and weight. It is highly suitable when board space and power profile must be minimized, especially suitable for use in communications and data networks. These suppressors can be used for overvoltage protection of DC/DC converters, line protection, and load protection in various USB circuits, audio lines, and other telecommunications applications.

It is noted that the application field of the DFLT27A-7 also includes the protection of RF switching networks, power management ICs, and other protection applications such as LAN lines, USB ports, and battery charging systems. It can also be used in solar array applications and in ground fault protection networks.

Working Principle

The DFLT27A-7 Transient Voltage Suppressor Diode is composed of a special silicon avalanche diode which is designed to absorb large amounts of transient energy without any significant damage. This diode also helps minimize the time it takes for a device to recover from transient failures.

When exposed to a surge of electricity, the silicon diode is triggered, forcing it to pass the current away from vulnerable components, thus providing excellent transient overvoltage protection. The DFLT27A-7 is designed to handle peak pulse currents of up to 25 A and peak pulse voltages of up to 260 V respectively.

In addition, the DFLT27A-7 is compatible with lead-free soldering processes and can be used in commercial, industrial and automotive applications.

Summation

The DFLT27A-7 Transient Voltage Suppressor Diode is a high-performance and high-efficiency diode designed to protect electronic components from excessive transient electricity. It is suitable for a variety of applications due to its superior electrical performance and small size. The diode is composed of a special silicon avalanche diode which helps minimise the time it takes for a device to recover from transient failures.
