TVS (Transient Voltage Suppression) diodes are important component in people\'s life. The SP1007-01ETG is a TVS diode designed specifically for protecting sensitive electronic circuits from high voltage spikes. After years of research, it has become an integral part of Electronic Circuit Protection (ESP).

Application Field

The SP1007-01ETG suppress transients that occur when a load such as a motor or light is switched on or off, or when the power is disrupted due to a power outage. It also offers protection from internal transients such as those generated by switching power supplies and voltage regulators. It is capable of suppressing voltage surges up to 8 kV, with a peak pulse power up to 1.2 kWh. The SP1007-01ETG is also capable of handling high energy and high frequency line noise.

The SP1007-01ETG is designed for industrial and commercial applications, including consumer electronics, computers and network equipment, and other applications where data loss due to surge and EMI (electromagnetic interference) can be a critical issue. It is ideal for industries where high reliability and performance are required, such as telecom, aerospace, medical, Industrial Control, Automation, Drive Systems, Automotive, and Sensors.

Working Principle

The working principle of the SP1007-01ETG is based on the principle of current diverting and clamping. It combines a high dynamic resistance component with a zinc-based diode. The diode prevents current from flowing in either direction, while the dynamic resistance component absorbs the voltage surge, limiting its magnitude.

When the spike reaches the TVS diode, the voltage threshold is exceeded and the dynamic resistance component is activated. This causes the voltage to be clamped, meaning that its magnitude is limited. The high frequency noise is then diverted back to the source, thus preventing damage to the circuit.

The SP1007-01ETG also includes a current limiting output stage, which prevents the TVS diode from exceeding its maximum voltage. This makes it capable of handling even the most extreme surges without the risk of damage to the protected circuit.

Conclusion

The SP1007-01ETG is a highly reliable TVS diode designed for protecting sensitive electronic circuits from voltage spikes and EMI. It combines a high dynamic resistance component and a zinc-based diode to limit the voltage magnitude and divert high frequency noise back to the source. It is ideal for industrial and commercial applications, making it a widely used protection device in many industries.
