Transient Voltage Suppression (TVS) Diodes are a type of solid-state overvoltage suppression device designed to protect sensitive components and circuits against damaging electro-static discharge (ESD) and electrical transients. The ESDARF03-1BF3 is a bi-directional TVS diode designed to provide overvoltage protection for high-speed data lines used in consumer, industrial, and communications applications. This article will examine the application field and working principle of the ESDARF03-1BF3 device.

The ESDARF3003-1BF3 TVS diode is suitable for applications that require a combination of robust ESD protection and low capacitance. It is a bi-directional device with a PGP configuration and integrated two ESDARF3003 chips per side. The device is designed to integrate with a USB 2.0 high-speed data interface with a low capacitance of 4.0pF (Type A connector) or 8.3pF (Type C connector). The ESDARF03-1BF3 is also designed for backward compatibility with USB 1.1 and can be used with any data rate up to 480Mbps.

The ESDARF03-1BF3 device features low clamping voltage (VC) of 15V and an adjustable overvoltage protection level (OVP) of up to 20V. The protection circuitry works by diverting any voltage in excess of the specified OVP level away from the sensitive electronics by passing it to the ground pin in a surge of current. The device also features excellent surge current capability of up to 500A, making it suitable for applications that require enhanced lightning protection.
