Introduction

Transient Voltage Suppression (TVS) Diodes are essential components used to protect electrical and electronic equipment from over-voltage surge damage. They are used to protect devices from voltage spikes or to act as a last line of defense against lightning or ESD strikes. The SMB10J16AHR5G is a TVS Diode specifically designed to protect against Electrostatic Discharge (ESD) and Electrical Fast Transient (EFT) impulses.

Features

The SMB10J16AHR5G is a transient voltage suppression diode which consists of four independent, low capacitance ESD diodes in a ultra small surface mount package. It has an operating temperature range of -40℃ to 125℃. It has a maximum peak pulse power dissipation of 10 watts (t=10μs) and a clamping voltage of 16.5V. These parameters make thisTVS diode perfect for protection against ESD and EFT impulses.

Application Fields

As a result of its high peak pulse power, low capacitance, and tight clamping voltage. The SMB10J16AHR5G TVS diode has a broad range of applications in the automotive, communication, consumer electronics, and industrial sectors. At the automotive level, it can be used to protect airbag circuits, engine control circuits, and wiring harnesses from damage to improve vehicle reliability and safety. In the communication sector, it can be used to protect data ports and other communication devices from ESD or EFT pulses.In the consumer electronics sector, it can be used to protect TV, cell phones, computers, and other electronic devices from ESD or EFT pulses.In industrial applications, the SMB10J16AHR5G can be used to protect industrial communication and control equipment from ESD pulses when combined with MOVs.

Working Principle

The working principle of the SMB10J16AHR5G is simple and effective. When an over voltage surge or electrical pulse is detected, the diode conducts the current away from the protected component, effectively protecting it from damage. The surge current is redirected to a capacitor which helps to dissipate it, preventing it from damaging the component. This diode works well in both AC and DC application and has very low response time (t.p=10μs) so it can act in a fraction of a second.

Conclusion

The SMB10J16AHR5G is an effective solution for protecting sensitive devices from electrostatic discharge (ESD) and electrical fast transients (EFT). Its high peak pulse power, low capacitance, and tight clamping voltage make it the perfect choice for a variety of applications across the automotive, communication, consumer electronics, and industrial sectors. Furthermore, its working principle is simple yet effective, making it an ideal choice for protection against ESD and EFT pulses.
