Transient Voltage Suppression (TVS) Diodes are integrated circuit protection devices that protect electronic equipment from damage due to transient overvoltages. The PGSMAJ8.0CAHR3G is one of a series of TVS Diodes suitable for use in various applications.

Description

The PGSMAJ8.0CAHR3G is a standard unidirectional TVS Diode with the functionality of both a zener diode and a thyristor. The device is housed in the 0805 size package and is RoHS compliant.

The rated reverse standoff voltage of the device is 8.0V, and it has a maximum standoff-clamping voltage (Vcm) of 48 V. Its peak pulse power is capable of dissipating up to 500 W, while its peak pulse current is 1500A for 8/20 μs waveforms.

The device also features very fast reaction time (3 ps typical), making it suitable for a wide range of applications.

Working Principle

Transient Voltage Suppression Diodes work on the principle of avalanche breakdown. The principle behind avalanche breakdown is that when the applied voltage to the PN junction reaches a certain value (the breakdown voltage) the PN junction undergoes a sudden breakdown and a large current starts to flow through the junction. This current is then limited by the internal resistance of the device, thus reducing the voltage across the junction.

The voltage at which the device starts to conduct is called the breakdown voltage. This is typically around 8V for the PGSMAJ8.0CAHR3G. However, the PGSMAJ8.0CAHR3G may conduct up to 48V in some cases. This is due to the fact that the device is rated for a maximum standoff-clamping voltage of 48V.

Application Fields

The PGSMAJ8.0CAHR3G is suitable for a wide range of applications due to its fast reaction time and reliable performance. It is commonly used in the following fields:

• Automotive Applications
• Electronic Computing and Telecommunications
• Industry Control Systems
• Medical Devices
• Solar Panels

The device can also be used to protect against electrostatic discharge (ESD).
