Transient Voltage Suppressor (TVS) diodes are fast-acting electronic devices that protect electronic circuits against transient overvoltage. Designed with a low wattage rating, TVS diodes have become a major component in electronic circuits that requires a very fast and reliable way to clamp high-voltage transients. One of the most popular TVS diodes used today is SMBJ10CA-TR.

SMBJ10CA-TR is a unidirectional diode that operates up to a maximum of 600 Watts peak pulse power handling capability. The SMBJ Series TVS diode provides a range of reverse voltage protection for sensitive electronic equipment. The SMBJ10CA-TR is designed to protect various devices ranging from flat panel displays, portable electronics, handheld devices, LCD TV, laptop computers, and more.

SMBJ10CA-TR Specification

SMBJ10CA-TR diode operates with a nominal standby current of 1μA, input voltage range up to a maximum of 14 Volts, and a maximum reverse standoff voltage of 10 Volts. Its reverse clamping voltage is only 17.0 Volts, indicating that it offers a very reliable protection mechanism against high voltage surges. Furthermore, the SMBJ10CA-TR diode has a unidirectional configuration which ensures conduction in one direction and not the other. This configuration is essential to ensure that devices are protected from component damage caused by reverse voltage that might arise from an avalanche effect.

How to Apply SMBJ10CA-TR Diodes

Before deciding to use SMBJ10CA-TR, it is crucial to understand the application for TVS diodes. As a protective device, SMBJ10CA-TR is commonly used in low voltage applications ranging from USB power supply, low-current and voltage logic-level lines, and other sensitive devices. It is not suitable for high voltage and power applications where energy absorption rating exceeds 600W.

When it comes to the application of SMBJ10CA-TR diodes, it is essential to place the diode as close as possible to the power source. This placement, also known as "clamping point," prevents voltage spikes from the source from reaching sensitive circuits. A common application of SMBJ10CA-TR in circuits is to place the device parallel to low-voltage power sources such as USB, data transmission lines, and LAN cables. It's also essential to implement the SMBJ10CA-TR diode in a multi-stage way by adding other diodes in series and parallel to ensure that the circuit is entirely protected against overvoltage spikes.

Benefits of Using SMBJ10CA-TR

SMBJ10CA-TR diodes are a popular choice in low voltage and sensitive power supply applications. Here some benefits that make SMBJ10CA-TR an ideal choice for your TVS diode needs:

1. Fast Clamping Speed: Compared to other TVS diodes available on the market, SMBJ10CA-TR offers a fast clamping speed which ensures that sensitive components are accurately protected against transient damages.

2. High-Level Performance: SMBJ10CA-TR offers high-level performance even with low-level input voltages.

3. Less Space Required: When it comes to saving space on the board, SMBJ10CA-TR is known to be an excellent choice. With its small package size, SMBJ10CA-TR is designed to fit most low-power applications without taking up much space.

In Conclusion

SMBJ10CA-TR is a TVS diode designed to offer reliable protection for sensitive electronic circuits that require low voltage power supplies. It provides excellent performance, fast clamping speed, and requires less space for your application. With the right implementation, you can protect your device against transient overvoltage for seamless operation and equipment longevity. However, it's essential to consider the right application and implementation of SMBJ10CA-TR to ensure that it adequately protects your device and circuits from overvoltage transients.
