TVS – diodes are a technology used to protect sensitive equipment against voltage transients. They are also known as transient voltage suppressors (TVS). The SA36A-E3/54 TVS – diodes are widely used in various applications where the protection of low voltage electronic equipment from over-voltage transients is essential. The SA36A-E3/54 is a single line unidirectional transient voltage suppressor with a working voltage of 34V. It is also rated up to 5.4A of peak impulse current.

The SA36A-E3/54 TVS – diodes are suitable for a variety of applications. They are commonly used in consumer electronics such as cell phones, PDAs, digital cameras and other electronic devices. They can also be used in automotive, computer and industrial applications. The SA36A-E3/54 TVS – diodes provide protection for most unprotected AC/DC power inputs up to 32V. They are often used to protect against lightning surges and automotive transients.

The working principle of the SA36A-E3/54 TVS – diodes involves two fundamental elements. The first is the avalanche breakdown property of the semiconductor material, which allows the diode to quickly absorb and dissipate excess voltage. The second element is the Zener breakdown mechanism which maintains the voltage at the device’s rated voltage limit.

For avalanche breakdown to occur, a certain amount of voltage must be applied across the semiconductor material. When this voltage is exceeded, the diode will begin to absorb the excess energy and dissipate it as heat. The advantage of this type of breakdown is its speed at which it can absorb and dissipate the energy. This helps to ensure that sensitive components are protected from damage.

The Zener breakdown mechanism operates slightly differently. Instead of absorbing the energy, the diode limits the voltage at the rated voltage value. This allows the components to be protected from extremely high voltages without restricting the normal operation of the equipment. The advantage of this mechanism is that it helps to maintain the stability of the equipment.

The SA36A-E3/54 TVS – diodes are available in a variety of packages, including SMA, DO-214, and TO-220 packages. These packages provide various mounting and protection options, as well as offering protection against a wide range of voltages. They also offer superior reliability and a wide working temperature range.

In conclusion, the SA36A-E3/54 TVS – diodes are a reliable and economical solution for protecting sensitive electronic equipment from over-voltage transients. They offer superior protection against lightning surges and automotive transients and are suitable for a wide range of applications, including consumer electronics, automotive, computers, and industrial applications. The working principle of the diodes works in two ways to provide a high degree of protection and stability. They are available in various packages to provide a variety of mounting and protection options, as well as offering superior protection and reliability.
