TSPB5H120S S2G Application Field and Working Principle

The TSPB5H120S S2G fast-recovery diode belongs to the category of single rectifiers. It is designed to provide low conduction and switching losses, as well as minimized noise and EMI. Although a single diode is usually enough for most applications, in some cases multiple ones are used. This allows creating a dual synchronized symmetrical low-loss half-wave duo, ideal for use in power switching applications.

Application Field

The TSPB5H120S S2G diode has a wide application field, where it features low onboard noise levels, reduced EMI generation and low switching losses. It is ideal for small signal and power supplies, chargers, DC/DC converters, and buck-boost designs. Additionally, its fast recovery generation time makes it suitable for lighting, power-line communications, servers, and other electrical systems like automotive and consumer electronics.

Working Principle

The TSPB5H120S S2G diode utilizes the principle of a diode bridge, where two positive and two negative diodes are formed in a rectifier bridge. The bridge allows the diode to conduct current in both forward and reverse directions, allowing it to convert AC voltage to a rectified DC voltage. Additionally, the built-in fast recovery feature allows for an increased time for reverse recovery, reducing losses in the switching process.

The TSPB5H120S S2G diode further helps reduce EMI by having low capacitance and voltage ratings. This means that the capacitance between the anode and cathode of the diode will be reduced, allowing for lower EMI generation. Also, having a reduced voltage rating ensures that the diode will work correctly in a wide voltage environment, and reduce any unsafe operating conditions.

Further Features

Apart from its fast recovery feature, the TSPB5H120S S2G diode also has a higher speed switching capability and improved thermal performance, which helps reduce any thermal stress during operation. Furthermore, its low power dissipation allows for minimal component losses, making it more efficient than other traditionally used diodes. Additionally, due to its specialized construction, the TSPB5H120S S2G diode can also be used in reverse bias conditions.

The TSPB5H120S S2G device is a fast-recovery single rectifier from the TSPB5H series, providing fast return times, low EMI generation, improved thermal performance, and low power dissipation, allowing it to be used in a wide range of applications.
