Introduction to BAV70T

The BAV70T is a diode array manufactured by Quanxin Components Co., Ltd. It is part of their extensive lineup of Rectifiers and Arrays. This diode array is a low-cost and general purpose solution that is well-suited to a number of different application fields. The typical operating temperature range of these devices is -55C to +125C, with maximum junction temperatures ranging from +150C to +175C depending on various parameters.

BAV70T Application Fields

The BAV70T diode array is designed for common consumer applications, including switching power supplies, industrial equipment, consumer electronics, computer motherboards, and other applications that require ultra-low-voltage operation and protection from voltage spikes. Additionally, its wide operating temperature range makes it suitable for extreme environmental conditions.

Moreover, the BAV70T is suitable for large-scale circuit board designs.It can easily be connected to external components such as capacitors and resistors to form a reliable switched-mode power supply that offers both high performance and superior power supply quality. Due to its low power consumption, the BAV70T can be used in an extensive variety of mobile applications, both consumer and industrial, where battery life is highly important.

BAV70T Working Principle

The BAV70T is a three-terminal diode array. It consists of three independent diode elements, with two diodes connected in series and the other two in a parallel configuration. Each diode has two electrodes; the anode is directly connected to the cathode of the other diode in the same pair and the other diode\'s anode is connected to the common anode in the array.

The BAV70T works by running a current across the diodes in series. In doing so, the current is prevented from flowing into an external circuit during the negative cycle of the switching waveform. This prevents electrical noise from travelling into the external circuit, as the current is interrupted at the negative peak.

Additionally, the BAV70T’s protection circuits provide a high degree of protection against voltage spikes. This ensures that even the most sensitive circuits, such as those found in mobile devices, stay protected from sudden increases in voltage.

Conclusion

The BAV70T diode array is the ideal solution for low-cost, general-purpose applications. It is widely used in switching power supplies, mobile devices, and industrial equipment, and can handle environmental conditions from -55C to +125C. Additionally, its protection circuits provide a high level of protection against voltage spikes. These features make the BAV70T diode array a great choice for any application that requires ultra-low voltage operation and protection from voltage surges.
