TVS - Diodes, also known as Transient Voltage Suppressors, are specialty diodes designed to protect sensitive electronic components from unwanted voltage surges. Their purpose is to protect vulnerable components by providing a low-impedance path to ground for any surges in current. The TVS can be used to absorb transients, attenuate EMI, and provide protection in both portable and automotive electronic applications. The DUP412VP5-7 TVS Diode is a high-speed, low capacitance, and low clamping voltage device designed to protect protection sensitive electronics from ESD, surge, and lightning strikes. It is ideal for various portable and automotive electronic applications as it features a low clamping voltage, fast response time, and superior EMI protection.

The DUP412VP5-7 is a single-channel Silicon ESD Protection Diode with an working voltage range of 5.0V. This particular TVS diode is designed to address the transition from parallel to perpendicular ESD events, and provides ESD protection for portable and automotive electronic applications. It features a very low capacitance of 10 pF, a fast response time of < 0.5 ns, and a low clamping voltage of 12V, making it ideal for applications such as USB, HDMI, automotive CAN line, and LCD driver protection. In addition to its low-capacitance and fast-response-time capabilities, the diode also has a high surge stability. It is capable of handling up to 8 A of peak transient current, making it highly suitable for protecting against high-voltage surges and lightning strikes.

The working principle of the DUP412VP5-7 is based on the principle of avalanche breakdown. When a reverse ESD voltage is applied to the diode, electrons and holes are swept into the junction, allowing them to recombine and release a tremendous amount of energy. This energy reduces the diode’s overall impedance, providing a low resistance path to ground for any potential transients. The TVS diode is able to dissipate the voltage before it can cause any damage to any of the protected components, making it a highly effective form of protection for electronic devices.

The DUP412VP5-7 TVS diode is a reliable and cost-effective way to provide EMI protection and surge protection for various portable and automotive electronic applications. Its fast response time, low capacitance, and low clamping voltage make it ideal for applications such as USB, HDMI, automotive CAN lines, and LCD drivers. When used in conjunction with other protective devices, it can provide effective ESD protection for any vulnerable electronic components, helping to ensure their longevity and performance.
