TVS or Transient Voltage Suppressors (TVS) diodes are mainly used to protect delicate circuits in electronic devices from high voltage transients which can cause damage. The 1N5659 is a popular type of TVS diode that is used for many applications. In this article, we will discuss the application fields and working principles of the 1N5659 TVS diode.

The 1N5659 is a unidirectional power TVS diode that can be used in many different applications where protection from high voltage surges is necessary. Some of the common applications that the 1N5659 is used for include overvoltage surge protection for computer motherboards, portable device chargers, and other electrical circuits. It is also used in low power DC-DC converters, automotive ignition systems, and power supplies. It is durable and reliable due to its extended life capability, and it is available in a wide variety of packages.

The 1N5659 is designed to protect the devices it is used for by providing a high amount of voltage protection. The diode is composed of silicon-oxide and is connected between the cathode and the anode in series with the protected device. When a high voltage surge is present, the diode will start to conduct current and gradually reduce the voltage to a safe level. This is known as the clamping voltage, and it will limit the amount of voltage that can go through the device.

The 1N5659 has a very particular working principle known as "avalanche breakdown", which allows it to dissipate large amounts of electrical energy. During this process, the electrons in the diode avalanche from one part to the other, and this spreads the energy across the device. It also produces a lot of heat which helps to dissipate the energy quickly. As a result, the charge is limited and the device is protected from any further damage.

The 1N5659 is a versatile and reliable solution for protecting delicate circuits in electronic devices from high voltage surges and transients. It is relatively small in size, which makes it ideal for applications where space is limited, such as portable devices. It is also the preferred choice for high voltage protection because of its efficient working principle and low power consumption. Using the 1N5659 can help to prevent costly repairs and replacements due to damage caused by voltage surges and transients.
