Transient Voltage Suppressor (TVS) diodes are used to protect sensitive electrical components against electrical transients induced by lightning or other power surges. The SMAJ26CA-QH is an unidirectional bi-directional TVS diode with a stand-off voltage of 26 volts. The device travels at a fast response time of less than 1ns and provides maximum protection of up to 26A.

The SMAJ26CA-QH is an ideal device for protection against power line transients, lightning surges, and other over voltage conditions. It also has a lower clamping voltage than most devices in its class. The device is designed for surface mount applications and is available in a variety of packages to suit the application requirements.

The SMAJ26CA-QH is specified for use in equipment sensitive to transient surge conditions in automotive equipment, automotive and industrial applications. It is also suitable for use in telecommunications and computer peripheral equipment.

The working principle of the SMAJ26CA-QH is based on the avalanche breakdown phenomenon or Zener breakdown phenomenon. The diode has a reverse breakdown voltage, which is known as its stand off voltage. When a surge due to a power overshoot is introduced, the diode begins to break down, allowing current to flow in the reverse direction. This current transfers the energy in the transient to the breakdown region of the diode, thereby dissipating the energy in the form of heat.

The SMAJ26CA-QH has an adjustable protection level that can be adjusted by simply changing the size of the metal-oxide varistor component. The device also has an additional surge current rating. This provides added protection in case of extremely high current surges. Furthermore, the device offers excellent overvoltage protection, and is capable of handling high frequency transients.

The SMAJ26CA-QH is available in various sizes and is suitable for a wide range of potential applications including automotive electronics, computers, communication systems, and aerospace and defense systems. It has a low capacitance, high ESD current capacity, and superior clamping capability. This makes it an ideal protection device for a wide variety of applications.
