TVS, or transient voltage suppressors, are components designed to protect electronic devices from high voltage and overvoltage transients.

SMA5J17AHE3/61 is a TVS diode specifically designed to protect products in limited space applications. This diode provides both overvoltage and over-current protection, which is critical for safety and reliability in today’s consumer electronics and industrial systems.

The SMA5J17AHE3/61 has a wide variety of applications, from consumer electronics to automotive, industrial to medical. It is suitable for both dual-rail and multiple line AC signals or DC power supplies. It can be used to protect against voltage transients caused by lightning, electromagnetic interference (EMI), electrostatic discharge (ESD) and other power surges.

When exposed to a surge voltage, the SMA5J17AHE3/61 clamps the voltage to a safe level by passing current through its silicon material. This process, known as avalanche breakdown, works on principle of avalanche multiplication. When an high electric field exceeds a certain threshold, the structure of the material will undergo changes resulting in a sudden decrease in breakdown voltage and an exponential increase in current flow. This ultimately dissipates the surge energy and clamps the voltage.

In order to ensure proper protection, the SMA5J17AHE3/61 has a wide operating temperature range of -55°C to +175°C. It also has a fast response time, typically less than 1 microsecond. This allows it to quickly react to potential surges and minimize damage to the underlying circuitry.

SMA5J17AHE3/61 is part of a series of TVS diodes designed for cost-effective overvoltage and over-current protection in limited space applications. By combining these features with a wide operating temperature range and fast response time, the SMA5J17AHE3/61 provides reliable protection in a wide range of applications.
