SMDJ6.5A-HRAT7

TVS - diodes are devices that help protect electrical systems from transient voltage surges, also known as overvoltage spikes. The SMDJ6.5A-HRAT7 is a particular type of TVS diode, specially designed to safeguard against damage carried by 6.5 A, 500 V surges. This diode is capable of withstanding high transient, reverse-strike voltages of 2000 W, 18 A and -20 A peak pulse overwhelming, and is approved for the specifications of IEC 61000 4-2 Level 4 conducted susceptibility and MIL-STD-1521C. This makes it suitable for use in a wide range of applications, including communication systems, automotive and industrial power management and security systems.

The SMDJ6.5A-HRAT7 helps protect equipment and circuits from any harm caused by voltage spikes, as it can detect any instantaneously elevated pulsed current and then divert it away, thus preventing the damaging current from ever reaching the circuits. This diode is also highly resistant to shock and vibration and has a reliable equipotential bonding characteristics.

The SMDJ6.5A-HRAT7 is typically used in applications where it is necessary to prevent both high conductive and high capacitive voltage transients from affecting the equipment operation within the system. For example, in installations for military requirements, the requirement may be to isolate the equipment from both surge currents such as lightning strikes and conducted electrical transients such as EFT/B.

The working principle behind the SMDJ6.5A-HRAT7 can be simplified to three critical steps:

1. Voltage Detection: Upon detecting a surge, the diode will immediately trigger its threshold voltage.
2. Current Clamping: Once the threshold voltage has been exceeded, the diode will immediately clamp the current by switching into its low impedance state.
3. Isolation: The diode will isolate the circuit and any associated systems and components from the electrical system, thus preventing interference and potential damage.

Once the surge has been diverted, the diode returns to its high-impedance state and is ready to protect the system again should there be another surge.

The SMDJ6.5A-HRAT7 can be used in a wide variety of applications. It is an excellent choice for industrial, consumer and military electronics, as well as medical and aerospace equipment. It is also suitable for automotive applications such as starting systems, ignition and fuel systems, oil pressure systems, and electric power transmission systems.

The SMDJ6.5A-HRAT7 is an extremely reliable and efficient device that can protect equipment and circuits against transient voltage surges in a wide variety of applications. Its reliable equipotential bonding characteristics, resistance to shock and vibration, and ability to withstanding very high transient voltages make it ideal for use in a wide range of industries.
