TVS - Diodes devices are an important component used in the protection of electrical systems against transient voltages, protecting sensitive electronic components from over-voltage transients. The A5KP440A-G Transient Voltage Suppressor (TVS) Diode is a popular and reliable surge protection device, primarily used in consumer and industrial applications. This article will discuss the application fields and working principle of the A5KP440A-G.

The A5KP440A-G is a bi-directional TVS device that is designed to protect sensitive electronic components from transient over-voltage transients. This device is commonly used in automotive applications, such as automotive multi-switch systems and vehicle reversing system protection, as well as in consumer applications such as automotive sound systems. The A5KP440A-G can also be used for protection in other industrial environments, such as motor control applications.

The A5KP440A-G is constructed from two silicon diodes connected in a symmetrical Hanhart configuration. This special configuration helps to ensure excellent clamping performance and minimal signal distortion. The device has a typical breakdown voltage (BV) of 5.4V with a peak pulse current of 6.5A. It is capable of clamping voltages up to 8.4V at the peak pulse current.

The A5KP440A-G is designed to begin clamping voltage peaks at a lower voltage than the breakdown voltage, allowing it to provide protection from much higher transient voltages. This device has a clamping voltage of approximately 40% of the breakdown voltage, which helps to ensure that over-voltage transients are smooth and well-controlled. This helps to ensure reliable protection for the connected electronics, as well as a moderate energy level absorbed from the transient over-voltage peaks.

The A5KP440A-G is also designed for high-speed operation and has a response time of less than 50 nanoseconds, allowing it to protect against fast-rising over-voltage transients. The device is also designed to dissipate a minimum amount of energy when clamping, reducing heat generated during operation and extending the life of the device.

In addition to the excellent electrical characteristics of the A5KP440A-G, it also has a small form factor of 0.5x0.3x0.2 inches, making it suitable for tight spaces. The device is also RoHS compliant, making it safe for use in a wide variety of applications.

In summary, the A5KP440A-G Transient Voltage Suppressor (TVS) Diode is a reliable and popular device used to protect sensitive electronic components from over-voltage transients. It is widely used in automotive, consumer and industrial applications due to its excellent electrical characteristics and small form factor. The device is robust and RoHS compliant, meaning it can be used safely in a wide variety of applications. The A5KP440A-G is the perfect device for any application that requires reliable surge protection.
