Introduction

The SMCJ16HE3/9AT is a Transient Voltage Suppression (TVS) Diode that offers protection for electronic circuits against transient voltage faults. This device has a wide range of applications due to its ability to suppress voltage transients in a fast and reliable manner. In this article, we will discuss the application field and working principle of the SMCJ16HE3/9AT.

Application field

The SMCJ16HE3/9AT is suitable for various applications in which it is necessary to protect circuits, including automotive electronic circuits. It provides protection against transients generated by electrostatic discharge, lighting strikes, or other high-voltage events. It is also suitable for power supply and telecom providers as it offers reliable protection against voltage transients. The device is designed to protect electronic circuits of automotive, industrial, and telecom systems.

Working principle

The SMCJ16HE3/9AT is a unidirectional TVS diode array that works by clamping voltage transients over a specific range of voltages. The device can be triggered when the voltage level of a transient exceeds its breakdown voltage. When this happens, the diode will direct the current to ground, thus protecting the circuit by limiting the peak voltage. The device is designed to work at low operating voltages, with an instantaneous peak clamping voltage of 16V.The SMCJ16HE3/9AT is designed for a wide range of operating temperatures from -55°C to 150°C. It is also designed to resist current surge up to 16A, and a peak pulse power entering the device (Ppk) of up to 600W. It has an excellent surge capability and can withstand a single surge of up to 6500A. In addition, it has a low reverse leakage current and can be used in environments with high humidity and dust.

Conclusion

The SMCJ16HE3/9AT is a Transient Voltage Suppression (TVS) Diode that can protect circuits against voltage transients. It can be used in a wide range of applications due to its ability to clamp voltage transients over a specific range of voltages and its resistance to current surges. The device offers reliable operation in a wide range of operating temperatures and environments, making it an ideal choice for a variety of applications.
