It can be used to also protect modems, ISDN terminals, and other communication devices from low-level, negative voltage transients in the data, control, and digital signal lines.

Application Field

The SA14A-E3/54 transient voltage suppression diode is intended for a wide variety of protection applications. It can be used in consumer, commercial, and industrial electronics. It is designed for use in AC/DC and DC/DC power conversion, uninterruptible power supplies, DC-DC converters, and surge protection. It is also suitable for use in audio, video, and data line protection.

Working Principle

The SA14A-E3/54 is a unidirectional bidirectional transient voltage suppression (TVS) diode. This device features a glass passivated junction for increased reliability. It is designed to protect voltage sensitive components from high voltage, high energy transient events. It works by providing a fast, low impedance path for current caused by high energy transient surges. The device absorbs and dissipates the surge energy and reduces reflected wave energy. It has a high junction-to-case capacitance which helps dissipate energy caused by long duration surges.

The device is capable of handling high surge currents up to 1A. Its fast response time makes it suitable for protecting sensitive components in AC-DC and DC-DC applications. Additionally, it can handle RC network transient suppression circuits. The device is IC compatible, which makes it suitable for use in PC board layouts. It is also RoHS compliant, making it suitable for lead-free boards and environments.
