30KPA43A-B Application Field and Working Principle

The 30KPA43A-B is a type of TVS (Transient Voltage Suppressor) diode. It has an abundant range of applications, primarily providing surge protection for devices connected to power supplies. Providing effective protection for a variety of devices, from digital or analog, to low voltage, high frequency or low frequency circuits, this TVS diode offers an ideal solution for proactive surge protection needs.

What makes the 30KPA43A-B so effective in such a wide range of applications is its working principle. This TVS diode works by utilizing the Zener effect, where an applied forward voltage above its breakdown voltage causes a dramatic increase in the device’s current based on the breakdown region’s characteristics, such as its junction temperature. In doing so, it quickly clamps the voltage at a predetermined value to protect the device from any damaging transients.

A very important factor when choosing the correct TVS diode for an application is its power dissipation capability, which is determined primarily by its clamping voltage. The 30KPA43A-B has a peak pulse power of 630W (10/1000µs) at a clamping voltage of 30V-33V, and a maximum clamping voltage of 43V. At these power and voltage levels, it provides excellent protection for a wide range of circuits and devices.

In terms of its form factor, the 30KPA43A-B is available in a standard SMA package with a minimum footprint area of 1.5mm x 1.3mm, making it suitable for surface mount applications with tight board space constraints. As a result, it can easily be implemented in various systems without compromising the performance of the overall design.

This TVS diode is also designed with an anti-surge construction which allows it to limit surge current peaks to a maximum of 23.5A (8/20µs) for improved protection against destructive transients. In addition, it is also capable of withstanding overload voltage of up to 50V, while its reverse standoff voltage is rated at 5.1V. All these features make the 30KPA43A-B an ideal device for protecting systems from various extreme conditions.

In conclusion, the 30KPA43A-B TVS diode is an effective, versatile, and powerful solution for protecting circuits against damaging transients. It utilizes the Zener breakdown effect to efficiently limit the device’s current flow and ensure reliable protection for a wide range of electronics.
