TVS Diodes are semiconductor devices specifically designed for protecting electronic equipment from Electrostatic Discharge (ESD) and other high-energy transients. The SMBJ300A-H is an ultra-small, 0201-footprint surface-mount TVS diode that is used to protect sensitive electrical components from ESD damage and other transients. The SMBJ300A-H is designed to provide maximum ESD protection with minimal footprint.

The SMBJ300A-H contains two high-speed, low-clamping-voltage, gold-plated Silicon Avalanche Diodes (SADs) integrated in an ultra-compact, 0201, 2-pin configuration that can withstand very high surge voltages up to 11 kV (IEC 61000-4-2). It provides an ultimate absorption level of ±30 kV (air), ±25 kV (contact). The device is available in an extremely small footprint, saving valuable PCB space and allowing for high-density solutions.

The SMBJ300A-H is an ideal TVS diode for use in a wide range of applications, especially in applications that require a small and compact footprint. It can be used in all types of sensitive electronic equipment, including communication systems, consumer electronics, automotive electronics, industrial and medical equipment, and more. Its low-profile construction makes it an ideal choice for space-constrained applications, which is why it is commonly used in portable electronics, including laptops and smartphones.

The SMBJ300A-H has a symmetric bidirectional transient suppression capability with a low clamping voltage of 79 V peak. This ultra-low clamping voltage minimizes over-voltage stresses and false triggering, resulting in a reliable ESD protection from transients. The bidirectional ESD suppression also reduces the number of components required, which further simplifies circuit designs and reduces board space.

The SMBJ300A-H also features a fast response time of 10 ns typical, up to 6 A peak pulse current, and it can operate over a wide temperature range from -40°C to +125°C. In addition, its gold-plated terminations provide a very low contact resistance between the contact pads and the PCB. This ensures that the response time and current handling capability of the device remain unaffected.

The SMBJ300A-H is an easy-to-use and reliable TVS diode with a small footprint and high ESD protection. It is designed to offer ESD protection without compromising on current handling capability and response time. It is also easy to install and provides excellent electrical contact reliability and performance.
