In this issue, Heketai introduces a bridge reactor product with a reverse withstand voltage of 1000V, which has a wide range of applications, stable and reliable products, and is a good discrete device product.

Heketai's bridge stack DB107S encapsulated by DBS has strong electrical characteristics, and its maximum DC reverse voltage can reach 1000V, forward current 1A, forward surge current 50A, reverse current 10µA and direct voltage 1.1V. DB107S has the characteristics of reverse high withstand voltage and large forward surge current, which is very useful for many high voltage and high current application scenarios. The forward current 1A of this bridge reactor product can be applied to relatively large current circuits. The characteristics of low back voltage and leakage current play an important role in rectifier circuit, and have high conversion efficiency, which can provide stable power conversion efficiency and meet the needs of various electronic devices and systems.

It also has the characteristics of glass passivation mold structure, low forward voltage drop, high forward surge current capacity and small surface mount equipment, and is suitable for adapters, photovoltaic inverters and other applications.

This product adopts DBS package, which has a very compact structure and small volume, and is suitable for miniaturized circuit structure. The design of the lead frame makes the lead and the chip board integrally connected, which not only ensures the stability of the connection, but also reduces the overall size of the package. DBS package is usually designed as a chip, which is convenient for automatic installation on the circuit board and improves production efficiency. Because of its small size and flexible pin layout, DBS package can adapt to various complex circuit layout requirements and facilitate circuit integration. The heat dissipation performance is good, and the advanced packaging technology is adopted to ensure the reliable connection between the chip and the pin, and reduce the failure caused by poor contact or mechanical stress. It has good environmental adaptability and can work stably in a wide temperature range and humidity conditions.

DB107S bridge stack products are mainly used for rectification in circuits, and are widely used in various electronic devices, such as LED, switching power supply, charger, inverter, adapter and modem, Ethernet power supply equipment, network equipment, etc.

Heketai, a DB107S bridge reactor, plays an important role in the switching power supply, which is responsible for converting the input alternating current into stable direct current and providing the required electric energy for the subsequent circuits of the power supply.

The above picture is a very common application circuit of DB107S bridge rectifier. When the AC signal is input to DB107S, it first goes through a transformer to reduce the voltage, and then enters the rectifier bridge circuit. The rectifier bridge circuit consists of four diodes D1, D2, D3 and D4. In the positive half cycle, D1 and D2 are conductive, and in the negative half cycle, D3 and D4 are conductive. In this way, the alternating current electric signal is divided into two signals, one is a positive half-cycle signal and the other is a negative half-cycle signal. These two signals are filtered by current filter to remove the ripple and get a stable DC signal.

In the charger and power adapter, DB107S bridge stack is used to convert alternating current into direct current required by the equipment, ensuring the safety and efficiency of the charging process. LED lamps usually need direct current to drive, and DB107S bridge stack can convert alternating current into direct current suitable for LED driving, which is widely used in LED lighting systems. In industrial control system, DB107S bridge reactor can be used in various occasions that need DC power supply, such as motor drive and sensor power supply.

In addition, DB107S bridge reactor is also widely used in computers, mobile communications, LCD TVs, smart homes, medical instruments, induction cookers and other products.
