TVS - Diodes

Transient Voltage Suppressor Diodes, more commonly referred to as TVS Diodes, are devices that help protect electronic components from voltage transients, which can be caused by ESD and EFT. TVS diodes are typically used to protect components in automotive, industrial, and consumer applications. This article will explore the PGSMAJ7.5AHM2G application field and working principle.

Application Field

PGSMAJ7.5AHM2G is a silicon transient voltage suppressor (TVS) diode designed for bi-directional transient voltage protection. It can provide protection from overvoltage transients induced by lightning, automotive load switching, and other fast transients in a variety of electronic equipment. This device is qualified to AEC-Q101 standard and is suitable for use in various automotive applications and LED lighting applications.

PGSMAJ7.5AHM2G is an ideal choice for protecting Line mode (LVDS, RSDS, etc.), signal lines in communications systems, and other sensitive components against overvoltages. It is also an excellent solution for LED lighting applications, providing transient protection between the LED driver and LED while maintaining a high optical illumination level.

Working Principle

PGSMAJ7.5AHM2G TVS diodes use a four-layer, unidirectional silicon structure. It can protect sensitive components from high-energy voltage transients by providing a low impedance path (clamping voltage) for the current pulse from the voltage transient. The forward voltage of the diode is guaranteed not to exceed the voltage rating that the component is designed for.

The PGSMAJ7.5AHM2G device has an ultra-low 8.6V clamping voltage, which allows it to protect against a wide range of overvoltage transients. It also has a low capacitance of only 6 pF, which minimizes signal degradation. The device features an extremely low leakage current of 1.2 μA, which helps reduce power dissipation.

Conclusion

The PGSMAJ7.5AHM2G TVS diode is designed for bi-directional transient voltage protection. It can provide protection from overvoltage transients induced by lightning, automotive load switching, and other fast transients in a variety of electronic equipment. This device is an ideal choice for protecting Line mode signal lines in communications systems, and other sensitive components against overvoltages, and is also an excellent solution for LED lighting applications.
