5.0SMDJ43A

TVS (Transient Voltage Suppressors) diodes protect operation circuit and equipment from electrostatic discharge (ESD) and surge attack. 5.0SMDJ43A is an unidirectional TVS diode which can be used for board level circuit protection from outside surge and ESD.

Application Field:

The 5.0SMDJ43A TVS diode is used to protect from one-line ESD, IEC 61000-4-2 (level 4), two-line EFT/B 3.5KV, IEC 61000-4-4, two-line ESD 15KV (air/contact) IEC 61000-4-2 (level 4), and two-line Surge 8/20uS. It is mainly used for port protection, such as USB, Ethernet, HDMI, DisplayPort, etc. It is also suitable for end products such as set-top box, home appliance, consumer electronics and automobile, etc.

Working Principle:

The 5.0SMDJ43A device is a unidirectional diode with the ESD protection circuit. When the external environment changes, the electrostatic discharge or surge pulse exceeds the rated voltage, it will form a lower voltage protection line. The ESD voltage is discharged to the ground through the circuit. This voltage is much lower than the actual peak voltage of the ESD attack to protect the sensitive components in the circuit. At the same time, it has the self-recovery protection function, which not only realizes the prevention of ESD damage, but also avoids the production of aftershocks, which is more secure.

Package Configuration:

The 5.0SMDJ43A device is available in a small SOT-23 package, which makes it easy to protect in a variety of equipment and product compartments. This package also ensures low parasitic capacitance, excellent ESD clamping, good surge withstand characteristics, low leakage current, and excellent thermal and electrical stability over temperature.

Conclusion:

The 5.0SMDJ43A diode provides excellent ESD and Surge protection for board-level circuits. Its unidirectional nature, small package, and low parasitic capacitance make it an ideal choice for protecting consumer electronics, automotive, and other equipment from ESD and Surge threats.
