TVS diodes are semiconductor components that offer protection to signals from electromagnetic interference. The SMF54AT1 is a bidirectional transient voltage suppressor (TVS) diode designed to provide protection against ESD, transient voltage, and EMI in a single component. This makes it ideal for a variety of applications, such as data and telecom systems, consumer and home audio equipment, automotive applications, medical systems, and industrial electronic applications.

The SMF54AT1 is designed to offer exceptional ESD protection. This TVS diode offers peak pulse capabilities up to 2.5kV and a clamping voltage of 5.0V for IEC 61000-4-2 Level 4 (15kV contact) or 8kV contact discharge protection. The reverse leakage current of the SMF54AT1 is low, at a maximum of 0.2μA for 5V, reducing discharge current on the protected lines.

The SMF54AT1 also features low capacitance and EMI attenuation, which allows it to satisfy a variety of requirements for EMI protection. It has an EMI attenuation of 54dB up to 1GHz, 44dB up to 5GHz, and 36dB up to 10GHz. The capacitance (Cdv/dt) of the SMF54AT1 is also low, at 0.3pF. This ensures minimal impact on signal integrity with minimal capacitive loading and reduced noise levels.

The SMF54AT1 has a working voltage range of 5.0V to 10V and is available in a variety of packages, including SOT-23, SOT-883, SOD-882 and DFN-10. It can also operate over a wide temperature range of -40°C to 125°C. This makes the device suitable for a variety of applications that require reliable protection with an extended temperature range.

The SMF54AT1 is designed to address the issue of ESD, transient voltage, and EMI. Its low capacitance, high EMI attenuation, and low leakage current make it an ideal choice for a variety of applications. The ability to operate over a wide temperature range and its variety of packages ensure that it can meet the demands of many different applications.
