Transil diodes, also referred to as Transient Voltage Suppressors (TVS), are devices that are designed to protect circuits from destructive transients which can be caused by electrical or physical overstressing. Transil diodes are generally designed to protect sensitive component, such as microprocessors, from operating beyond their absolute maximum ratings. They are commonly used to protect power supplies, data lines, and other sensitive components and circuit from transients.

SMAJ13A-QH is a type of Transil diode that is specifically designed to protect equipment with rectified voltages up to 6.5V from destructive transients. It is designed to absorb high energy surges on the output of power supplies. It has an ultra-fast response time and can absorb up to 1500W of peak power.

The SMAJ13A-QH is suitable for a wide range of applications, from industrial electronics to consumer electronics. It can be used to protect computers and computer peripherals from power surges, as well as to protect other electronic equipment subjected to high electrical noise levels. It is also suitable for automotive applications, where it can help to protect sensitive on-board electronics from voltage spikes caused by static discharges.

The working principle of SMAJ13A-QH is simple. When an external transient has a current higher than the breakdown voltage of the device, the diode will be switched on and a short-circuit will be formed between the anode and the cathode of the device. This will divert the transient current away from the protected component, ensuring that its operation is not affected by the transient.

The SMAJ13A-QH is able to absorb high peak currents and is also able to withstand multiple transients in succession. This makes it an ideal choice for applications that require protection from multiple transients. It also has a low clamping voltage, meaning that it can absorb more energy before tripping. This is especially useful in applications where transients are common.

In conclusion, SMAJ13A-QH Transil diodes are an effective way to protect sensitive components and circuits from transients. They are suitable for a wide range of applications, from industrial to consumer electronics. They have a fast response time and can absorb high peak currents and multiple transients in succession. Their low clamping voltage also make them particularly useful where transients are common.
