TVS – Diodes are the components of most modern electronic devices. These devices are known to provide protection to vulnerable electronic components from electrical stress such as electrical over-voltage or over-current. TVS-Diodes, especially SRDA3.3-4, are commonly used in current protection and transient voltage protection applications. The latter is particularly effective in eliminating excessive transients in current and voltage that might damage electronic components.

An SRDA3.3-4-TBT is a Transient Voltage Suppressor diode that helps regulate and protect equipment from transients or voltage over-voltage. It is applicable for a wide range of voltage applications, up to 5KV peak/1KV at 10 amperes peak for unidirectional protection, and up to 3KV peak/1KV 13A peak for bidirectional protection. It is a two-terminal component with low capacitance. The SRDA3.3-4-TBT can be used in a variety of industries, such as equipment used in travel and high-performance spaces.

The working principle of a SRDA3.3-4-TBT is fairly straightforward. Upon sensing a voltage that is higher than its clamping voltage, the diode will begin to conduct. As the voltage rises, the current passing through the diode begins to increase rapidly and the diode begins to conduct, absorbing the energy and limiting the voltage seen by the electronic device. The current will then begin to decrease as the voltage drops, and the voltage again becomes safe for the device.

The SRDA3.3-4-TBT can provide protection for various types of electronic loads spanning from basic consumer & entertainment electronics to industrial transportation & defense equipment. Other areas in which the component offers benefits include automotive control/lighting systems, power supplies, broadcast systems, computer peripheral systems and high-speed data interface processors.

The SRDA3.3-4-TBT is also ideal for applications where noise immunity is important due to its low capacitance that ensures signal integrity. It has excellent clamping capabilities and can effectively protect the connected device from over-voltage events, while its thin profile makes it easy to use in a wide variety of applications and even when space is limited. In addition, the device is highly reliable, with a low failure rate due to its robust design.

In conclusion, the SRDA3.3-4-TBT offers many advantages that make it an ideal choice for many applications. It is highly reliable and offers excellent protection against transient voltage from over-voltage events. It is a two-terminal device with low capacitance, making it suitable for applications where noise immunity is important. It has a thin profile that allows it to be used in small spaces. Finally, it offers a wide range of voltage applications, making it suitable for use in many different industries.
