TVS-diodes are electronic devices that help protect sensitive components in circuits from damage due to voltage spikes or transients. They are also used to protect communications equipment from electrical surges. The SMF60A-TP is a special type of TVS-diode, designed to provide a higher level of protection for a variety of applications. In this article, we will discuss the application fields and working principle of SMF60A-TP.

The SMF60A-TP is a dual-bi-directional TVS-diode, designed for surface mount applications and suitable for protecting from transient surge voltages up to 600W peak pulse power. It is commonly used in applications where improved reliability and low capacitance are required, such as automotive electronics, telecoms equipment, data buses, and industrial control equipment. It offers excellent protection against electrical fast transients, such as lightning-induced surges, as well as from electrostatic discharge.

The SMF60A-TP is composed of two back-to-back TVS-diodes, each with their own internal protection-zone. Each diode has its own trigger threshold and reverse standoff voltage. The two diodes share a common anode pin and, when both trigged simultaneously by an applied surge voltage, the SMF60A-TP will switch on with a low clamping voltage, providing a high level of protection to the circuit. The SMF60a also features a fast response time of less than 1ns, reducing the risk of damaging the sensitive components in the circuit by any transient surges.

The working principle of the SMF60A-TP TVS-diode is based on the avalanche breakdown effect. This is when an applied voltage increases exponentially until the breakdown breakdown voltage is reached, at which point the diode’s I-V characteristics will switch and allow current to flow. The breakdown voltage is determined by the diode’s construction. The SMF60A-TP contains two distinct diodes in the same package, each with its own breakdown voltage that can be tailored to match specific application requirements.

The SMF60A-TP TVS-diode offers superior protection due to its higher surge current handling and lower clamping voltage. It also has a wide operating voltage range, making it suitable for a variety of application fields, including automotive electronics, telecoms equipment, data buses, and industrial control equipment. In addition, the device has a low capacitance that helps reduce signal distortion, providing improved signal integrity. The SMF60A-TP also has a low package height, allowing for easier PCB design and mounting.

In summary, the SMF60A-TP is a dual-bi-directional TVS-diode designed for surface mount applications and capable of providing superior level of protection against transient surges. It has a wide operating voltage range, low capacitance, low package height, and fast response time. The device is ideal for automotive electronics, telecoms equipment, data buses, and industrial control equipment.
