TVS (Transient Voltage Suppression) diodes are a type of surge protection device that absorbs most of the electrical spikes, surges, transient and high voltage pulses that can occur both in automotive and industrial applications. The PGSMAJ70AHM2G is one such diode that is designed to protect against transient voltage signals in excess of the rated peak pulse power. It provides an economical approach to suppressing electrical transients and surges in a wide variety of applications, such as in motor drives, machine controllers, and HVAC systems.

The PGSMAJ70AHM2G is a type of TVS diode that is specifically designed to protect against peak pulse power levels up to +70A (w/2/20uS). It features a stand-off voltage of 6.6V, a peak pulse power level of 360W, and a clamping voltage of 8V (max). The TVS diode also offers excellent surge capability and fast pulse response. It has a low clamping voltage and a peak clamping ratio of 140A:1V. The diode also features an ultra-low standoff voltage, making it ideal for applications with high voltage spikes.

The PGSMAJ70AHM2G is commonly used in automotive and industrial applications, as it is capable of handling considerable peak current and short duration voltage surges. It provides an economical alternative to multi-level protection solutions for most power supply and network applications. Furthermore, the PGSMAJ70AHM2G runs at a low operating temperature, providing improved reliability and on-resistance compared to other comparable TVS devices.

The PGSMAJ70AHM2G operates according to the process of avalanche breakdown. This type of breakdown occurs when the voltage applied across the junction of a diode is increased to a level that causes electrons and holes to combine and produce a conductive path over which current can flow. This current flow also produces energetic carriers (electrons and holes), which can travel further through the semiconductor material. This causes the voltage across the junction to increase until it reaches a peak value.

The PGSMAJ70AHM2G uses avalanche breakdown as its protection mechanism and it is capable of absorbing peak pulse currents in excess of 140A (with 2/20us pulse) and clamping voltage at 8V (max). The diode is also designed to absorb any overvoltage spikes that occur, thus providing effective protection in applications where these spikes are known to exist.

The PGSMAJ70AHM2G diode is suitable for use in a wide variety of applications, including automotive, industrial, and electrical/electronic components and systems. It can be used to protect against overvoltage and power transients in these applications. It is also commonly used in motors, inverters, surge suppressors, and power supplies, as it provides protection from unwanted voltage and power fluctuations. In addition, the diode is designed to provide long-term reliable protection against power surges and transient voltage signals.
