UGF15HTHE3/45

Diodes - Rectifiers - Single

The UGF15HTHE3/45 is a single rectifier diode from STMicroelectronics. It is designed as a low-drop SOD123 package of 3.2 mm, is a Schottky technology, and has a voltage of 45 V.

The diodes are basically built using two layers of semiconductor materials and can be used to provide a continuous, non-linear current control. The UGF15HTHE3/45 can also be used in a variety of applications such as power switching, polarity protection, over-voltage protection, and voltage clamping. Other uses of diodes like driving LEDs, constraining voltages and protecting circuits against transients are also supported by this solution.

Application Field

The UGF15HTHE3/45 diode is mainly used for power supplies and in power supply circuits supporting operation from a singlepolarity DC input. It’s designed to provide protection against overvoltage, reverse voltage, and electrical transients from high-voltage sources. It also has fast switching times, making it ideal for use in power-switching applications. The UGF15HTHE3/45 diode provides a low-power way to provide protection for circuits against electrical transients and surges, as well as to regulate voltage.

The diode is also well-suited for use in applications such as battery chargers, voltage-regulated power supplies, power switching, and protection circuits. It can also be used to provide protection against electrostatic discharges (ESD).

Working Principle

The UGF15HTHE3/45 diode works on the principle of rectification, which is the conversion of an alternating current (AC) voltage into a direct current (DC) voltage. It does this by allowing current to only flow in one direction. When an AC voltage is applied to the diode, it only allows current to flow in one direction (the anode), while current is blocked in the opposite direction (the cathode). This eliminates any reverses in the current flow, essentially turning AC voltage into DC voltage.

By adding the UGF15HTHE3/45 diode to the power supply circuit, it can protect the system from any overvoltage and current surge conditions. The diode’s low-voltage drop ensures that the power supply circuit can operate more reliably and efficiently. Additionally, the diode’s fast switching times enable it to protect against transients, as well as provide voltage regulation.

Conclusion

The UGF15HTHE3/45 is a single rectifier diode designed for use in power supplies and power supply circuits. It can provide efficient protection against overvoltage, reverse voltage, and transient conditions. Additionally, it has fast switching times, allowing for power-switching applications and voltage regulation. The UGF15HTHE3/45 is a reliable, low-drop SOD123 package configured for 3.2 mm of width and Schottky technology.
