TVS diodes, also known as Transient Voltage Suppression (TVS) diodes, are specialized devices designed to protect electronic systems from high-voltage transients, typically caused by electrostatic discharge (ESD). The SMAJ440E3/TR13 is a bidirectional TVS diode designed for transient protection from lightning and inductive switching surges. It offers superior clamping behavior over the full operating temperature range, and is available in a ubiquitous SMA package.

Application Field

The SMAJ440E3/TR13 TVS diode is designed to protect sensitive electronic equipment from high-voltage transient surges. It is particularly suitable for industries such as automotive, commercial, residential, and communication, where sensitive digital equipment needs to be safeguarded against electrical transients. The device operates in a bidirectional mode and is designed to protect two lines of data in both directions.

The SMAJ440E3/TR13 device can protect data lines from transient voltages and is suitable for USB, Ethernet, DVI, RS-232, and other applications. It is also suitable for power protection when connected between the power line and ground, providing protection from transient surges up to 500 watts.

Working Principle

The SMAJ440E3/TR13 TVS diode utilizes a unique design that combines active and passive components to protect sensitive electronic equipment from transient surges. The device features a high surge current clamping capability with excellent thermal stability and is able to respond to fast voltage transients, ranging from 0.2 nanoseconds to 10 nanoseconds.

The device consists of a two-terminal structure composed of a diode and a Zener diode, with an integrated capacitance structure. When a voltage transient occurs, the Zener diode starts to conduct, effectively limiting the transient voltage at a maximum value of 12.1 Volt (BreakDown Voltage - VBR). At the same time, the diode and capacitance structure offers protection from transient voltages by diverting them to ground and buffering the transient\'s sharp voltage edges. The design of the device effectively protects sensitive electronic equipment from high voltage transients.

Conclusion

The SMAJ440E3/TR13 TVS diode is a bidirectional protection device designed to protect sensitive electronic equipment from high voltage transients, due to ESD and inductive switching. It offers superior protection with excellent thermal stability and fast response time, in a ubiquitous SMA package. The device can also protect power lines from transient surges, up to 500 watts, and is suitable for a range of applications such as USB, Ethernet, DVI, and RS-232.
