TVS diodes are an essential component in most electronic designs. They provide protection against transient voltage surges such as those caused by lightning strikes, electrical shorts, or other external disturbances. The SMCJ440AE3/TR13 is a TVS diode specifically designed for protecting sensitive components in a variety of applications, such as computer systems, telecommunications systems, instrumentation, power distribution, and many more. This article will discuss the application fields and working principle of the SMCJ440AE3/TR13.

Application Field

The SMCJ440AE3/TR13 is a high-performance, bi-directional, low-capacitance TVS diode designed specifically for protecting sensitive components from surge voltages. It is rated for 400 Watts peak power dissipation, with a maximum clamping voltage of 8.5V for a 10/1000us waveform. It is ideal for protecting against high-voltage transients in a wide variety of applications, including computer systems, telecommunications systems, instrumentation, and power distribution. In addition, it is capable of operating at temperatures ranging from -55°C to 175°C. The SMCJ440AE3/TR13 is also suitable for many automotive applications, including powertrain systems, vehicle sub-systems, and vehicle electrical components.

Working Principle

A TVS diode works by providing a low-resistance path for transient current to flow. When a surge in voltage occurs, the diode begins to conduct, allowing the transient current to flow through the diode and away from the protected component. The SMCJ440AE3/TR13 TVS diode is a reverse-biased device, meaning it is designed to be in a non-conducting state until a transient voltage surge occurs. When the surge occurs, the diode begins to conduct and the current is diverted away from the protected component. The diode can be effectively used to protect against a variety of transient voltages, and can handle peak currents up to 28A.

Conclusion

The SMCJ440AE3/TR13 TVS diode is an ideal choice for protecting sensitive components from transient voltage surges. It is rated for 400 Watts peak power dissipation, with a maximum clamping voltage of 8.5V and is capable of operating at temperatures ranging from -55°C to 175°C. It is ideal for protecting against fast transients in applications such as computer systems, telecommunications systems, instrumentation, and power distribution. Furthermore, it is suitable for many automotive applications as well. The SMCJ440AE3/TR13 is a reverse-biased device, meaning it is designed to be in a non-conducting state until a transient voltage surge occurs. When the surge occurs, the diode begins to conduct and the current is diverted away from the protected component.
