TVS-Diodes (Transient Voltage Suppressor-Diodes) are an important part of electronic equipment and circuit protection, and the SA45AHRO is a type of TVS-Diode. It is a solid state device designed to protect sensitive electronic components devices from either high or low voltage transient and electrostatic discharge. It is usually used for the protection of sensitive electronic devices and systems, such as computers and related peripherals, telecommunications, consumer electronics, industrial electronics, automotive electronics, and medical equipment.

The SA45AHRO is available in an extreme wide operating temperature range, from -55℃ to +115℃. With an 8mm lead spacing, the device is highly reliable for its small size. The breakdown voltage of this diode ranges from 3V to 250V. Furthermore, its parasitic inductance is extremely low, resulting in a fast response time and small overshoot.

The working principle of the SA45AHRO is based on the principle of static excitation. Whenever a voltage greater than the breakdown voltage is applied across the leads of the diode, an avalanche breakdown occurs. As the breakdown voltage is exceeded, a low resistance path is established between the two leads, allowing the current to flow through. This current then decreases rapidly as the voltage reaches a stable level. This is because the device is designed to clamp voltage spikes quickly.

The SA45AHRO is a cost-effective and efficient device for protecting sensitive electronic equipment from over voltage and electrostatic discharges. Its fast response time and small overshoot make it an ideal choice for applications where overshoot is a concern. Its wide operating temperature range and small size enable the diode to be used in a variety of electronic systems, such as computers and telecommunication systems. Therefore, the SA45AHRO is an excellent choice for protection of electronic equipment from transient and ESD events.
