TVS - Diodes

Transient Voltage Suppressors (TVS) are semiconductor devices that provide bidirectional, ultra-fast (sub-nanosecond) protection from surges, spikes, and other high energy transients. This type of diode is a unidirectional or bidirectional, semiconductor-based surge suppressor, designed to clamp high transient voltages or currents, and prevent them from causing damage to sensitive circuitry in sensitive applications. It is important to select the correct model for your particular application.

SMA6T28CAY Application Field and Working Principle

SMA is the abbreviation of Surface Mount Transient Voltage Suppressor. The SMA6T28CAY is a 600W, 5.0V unidirectional TVS designed to protect sensitive electronic components from damage due to electrostatic discharge (ESD) or other power surges. The device is also suitable for down hole oil well applications in explosive atmospheres.

The SMA6T28CAY is capable of handling 600W of power for a short duration. This is important for protecting sensitive components from damage due to high voltage transients. The device is made up of two back-to-back connected zener diodes, each with its own anode and cathode. An internal connection is provided between the two diodes to ensure the correct operation of the device. When a voltage transient is applied to the anode, the device momentarily shunts the current away from the protected circuit, and the excess current is diverted to the cathode.

The SMA6T28CAY is designed and manufactured to meet the environmental and safety standards of the oil and gas industry. It is rated to work in temperatures from -40 to +125°C and is compliant with HALT/HASS testing. It also meets UL 94V-0 flame retardant rating for plastic packages.

This device also provides excellent electrical performance. Its ESD rating is 8KV and its rated peak power is 600W (10/1000 μs). The clamping voltage is 4-6VDC, and the peak clamping current is 10A. The SMA6T28CAY is also designed to have a fast response time, so it is able to protect sensitive components from high voltage transients in a short amount of time.

The SMA6T28CAY is a great addition to any system which requires protection from high voltage transients. It is designed to provide reliable and effective protection in a wide range of conditions, so it is an excellent choice for applications in the oil and gas industry, or any application requiring ESD protection.
