Transient Voltage Suppressor, or TVS, are highly robust diodes designed to protect a circuit from transient electrical events, such as Electro Magnetic Interference (EMI) or spikes. SMAJ18A is a DV Surge Protection TVS Diode that offers unsurpassed reliability, superior circuit board space savings, and low cost. Its superior performance and reliability make it a popular solution for many applications where high-memory transient protection is required.

TVS Diodes are designed to provide protection from electrical surges, noise, and transient voltage spikes. They are essential components for any circuit where power is exposed to sudden interruptions such as AC mains and automotive applications including plugging and unplugging of equipment. The SMAJ18A diodes are designed to react fast to transients and to provide an almost instantaneous clamp to protect the signal.

When a high voltage transient event such as an ESD pulse or EFT surge occurs, the semiconductor junction of the SMAJ18A device begins to conduct. The voltage rating and power rating of the SMAJ18A ensures that it does not fail or become damaged when subjected to large transient events. Capacitance value is also important when using TVS diodes, as it determines how quickly the diode can react to a transient event. SMAJ18A is designed with high capacitance values to ensure a fast response time to transients.

SMAJ18A diodes have outstanding ESD and EFT protection capabilities that make them suitable for both high-end and low-end consumer electronics applications. The device can be used to protect USB ports, cables, data lines, and audio and video signal lines from damage caused by over-voltage transients. It also offers Class I and II protection for automotive applications where reverse bias protection is required. The device features an ultra-low leakage current of less than 1μA and high peak pulse power capability with low peak voltage clamping.

SMAJ18A has many advantages over other TVS Diodes, such as tin-plated leads for superior solderability, as well as thick film resistor element with short switching time and low clamping voltage. The component is designed with several mounting options including dip, dip socket, and header. The small size of the device also makes it ideal for use in tight spaces. Furthermore, the device is designed to meet industry standard mechanical sizes and it is RoHS compliant.

In summary, SMAJ18A is a highly reliable and robust TVS Diode that provides superior circuit protection from transient electrical events. It is designed with high capacitance values for fast reaction time and low clamping voltage. It also offers excellent solderability, high reverse bias protection, and RoHS compliance. The device features a small size and several mounting options for easy installation. SMAJ18A is suitable for a variety of applications in automotive and consumer electronics, including USB ports, cables, and data and signal lines.
