Diodes - Bridge Rectifiers are widely used for transforming and rectifying AC voltages into DC voltages. The DB151STR Bridge Rectifier is a particularly versatile and widely used bridge rectifier that encompasses a range of applications. This article takes a look at the different applications of the DB151STR, along with its working principle.

The DB151STR is a 25A bridge rectifier designed with two diodes in a bridge configuration possessing ultra-low forward voltage drop (typ. ≤ 1.15V) and requires no hardware protection against current or voltage fluctuations. It is created using low-loss Schottky process technology, making it capable of withstanding temperatures from -55 to +175°C and is available in different capacitances.

Application fields

The DB151STR is primarily used for voltage conversion and rectification in any application where AC must be converted to DC, and rectified to a pure DC current. Some common applications of the DB151STR include automotive electronics, telecoms, industrial controls, LED lighting, solar energy, and UPS (uninterrupable power supply).

Working principle

The working principle of the DB151STR is based on the same principle as other bridge rectifiers. It utilizes two diodes in a bridge configuration. When an alternating voltage is applied to the two diodes, the diodes ‘on’ phase alternates, resulting in a direct current across their terminals. The current is then rectified in a way to produce a unidirectional current.

The DB151STR is much more efficient than regular bridge rectifiers because it uses Schottky diodes. These diodes have a much lower forward voltage drop, meaning that less power is wasted as heat. This makes them ideal for power conversion, such as solar energy and telecoms where losses due to heat need to be kept to a minimum.

The other major advantage of the DB151STR Bridge Rectifier is its wide operating temperature range. It is able to operate in temperatures ranging from -55°C to +175°C, making it suitable for a variety of industrial applications.

Conclusion

The DB151STR is a versatile and efficient bridge rectifier used in many different applications. It is capable of transforming and rectifying AC voltages into DC voltages with minimal losses due to its low forward voltage drop and wide operating temperature range. The DB151STR is an ideal choice for any application that requires voltage conversion.
