A5KP58A-G Circuit Protection

TVS devices have grown significantly in popularity over the past few years, due to their ability to preserve equipments from large destructive transients. TVS-Diodes, typically used as a protection device in electronic circuits, are one of the active components that expected to show a fast response in order to limit the surge or transient voltages that sometimes appear in many application fields. A5KP58A-G is a Transient Voltage Suppressor (TVS) Diode manufactured by Diodes Incorporated. This device is designed to protect components from voltage overshoots while offering reliable and cost-effective protection.

The A5KP58A-G is a unidirectional TVS diode available in SOD-123FL and SOD-323 packages. It is designed to protect components from high voltage transients and ESD pulses in a variety of applications.

The A5KP58A-G offers a wide range of features that make it well suited for a variety of application fields, including automotive, industrial, and consumer applications. It provides excellent level of protection from over-voltage transients, with an ESD protection up to ±15kV Human-Body Model and ±8kV Charged-Device Model, as well as a peak pulse power (1.2/50µs) of 850W (10/1000µs). Moreover, it has a low leakage current, high resistance to electrical fields, and a low clamping voltage.

The A5KP58A-G has a working principle based on Zener Breakdown. When the working voltage U S of the diode is exceeded, the zener effect applies and the transistor starts to conduct electrons, carrying current and limiting the over voltage. This offers protection for electronic components and circuits from large voltage changes.

Thanks to its high surge capability, low capacitance and minimum leakage current in reverse blocking mode operation, the A5KP58A-G is well capable of providing a reliable protection against over voltage for a large variety of applications requiring an elevated ESD robustness. It can be used in automotive applications to protect ECUs and sensors from extreme conditions, in industrial and consumer applications as touch panel protection, audio line protection, and more, and also in 5V and 12V DC power supplies and other power applications.

In conclusion, the A5KP58A-G is an excellent example of a TVS-diode design and a reliable cost-effective protection against over voltage transients and ESD pulses. Its wide variety of features, high surge capability and ESD protection make it a versatile and reliable choice for many application fields.
