SP3003-02JTG

TVS (Transient Voltage Suppressors) diodes are essential components used in electronic circuits to protect them from voltage spikes and transients. The SP3003 series of TVS diodes from Vishay Semiconductor are perfect for AC line current applications and have an impressive power rating of up to 6A. In this article, we will discuss the application fields and working principle of the SP3003-02JTG TVS diode.

Applications:

The SP3003-02JTG TVS diode is suitable for a wide range of AC current applications such as AC motor speed control applications, AC power supplies, household UPS systems, surge suppression circuits, etc. The diode provides excellent over-voltage protection when used in applications that require robust surge immunity. In addition, the SP3003-02JTG TVS diode has the capacity to absorb operating surges of up to 2300W peak power in a single line.

Working Principle:

The SP3003-02JTG TVS diode is based on the principle of avalanche breakdown. Avalanche breakdown occurs when a voltage applied to a reverse-biased diode is above a certain critical level. When this threshold is exceeded, the carriers in the depletion region begin to accelerate and gain energy, eventually leading to electron-hole pairs being produced within the diode junction. This sudden increase of current within the diode leads to a large, rapid increase in voltage drop across the diode, and thus limits the over-voltage applied to the electronic circuit.

The SP3003-02JTG also has an integrated clamp which is designed to absorb high transient voltages. The diodes exhibit low dynamic resistance, providing superior ESD protection. The SP3003-02JTG also incorporates sensitivity options which allows it to be matched to different voltage and current requirements. Furthermore, the diode is capable of absorbing up to 6 Amperes of peak surge current.

Conclusion:

The SP3003-02JTG TVS diode is an essential component used in many electronic circuits to provide robust surge immunity. The diode has the capacity to absorb up to 6 Amperes of peak surge current and has high ESD protection. The diode is capable of operating at a wide range of temperatures, making it suitable for a variety of different applications. Thus, the SP3003-02JTG TVS diode is the perfect choice for any AC current application.
