PGSMAJ17AHR3G Circuit Protection

TVS - Diodes (transient voltage suppression diodes) are an important component in the development of any modern electronic circuit. They act as a protection device against damaging electrical transients, which can be caused by voltage spikes from electrostatic discharge, lightning strikes, and power surges from the electric power line. The PGSMAJ17AHR3G TVS diode is designed specifically for use in the automotive industry, where it offers protection against voltage transients in the 12V DC electrical system.

The PGSMAJ17AHR3G is a three terminal, capacitor-diode-resistor (CDR) structure, consisting of a capacitors, diode, and resistor integrated on the same IC. The first stage of the protection is provided by the capacitor, which stores the energy from the transient and then releases it slowly, thus limiting the peak current that passes through the diode. The diode then controls the voltage across the device, and its breakdown voltage is equal to the maximum clamping voltage for which the device is rated. Finally, the resistor at the output prevents any oscillation that can occur due to capacitive loading.

The rated break down voltage of the PGSMAJ17AHR3G is 17V, and its peak pulse power handling capability is up to 400W, making it ideal for automotive applications such as the protection of the main power line. It can also be used for protecting peripheral lines such as the signals network in an automotive system, and its fast response time ensures that it can effectively suppress voltage transients even under extreme conditions.

In addition to its high protection capability, the PGSMAJ17AHR3G also offers a host of other benefits. Its low ESR helps to promote high switching performance, while its small package size (SMD) makes it ideal for use in space restricted applications. It is also fully AEC-Q101 qualified, so it meets the stringent industry standards for reliability and quality.

The PGSMAJ17AHR3G is a highly effective and reliable transient voltage suppression diode that is specifically designed for use in automotive applications. Its protective capabilities and features make it an ideal choice for protecting modern electrical circuits from potentially damaging voltage transients.
