TVS diodes have been developed to absorb and suppress transient voltage surges in electrical circuits. The SP1002-02JTG is an example of such a device. It is designed to protect a circuit from voltage spikes or transients, generally caused by Electrostatic Discharge (ESD) or external inductive switching, and other sources of overvoltage transients.

The SP1002-02JTG is built with special semiconductor materials designed to clamp voltage or energy to a specific level within a certain period of time. As a two-terminal device, it is designed to handle transient voltages of up to 20.5V and is rated for two-pulse event dissipation of 25A, 52.5A, and 250A, with maximum breakover voltage of 12V. Voltage increasing much more than the maximum breakover voltage can cause permanent destruction of the device.

The SP1002-02JTG works as a current limiter to suppress transients. Whenever it is exposed to a higher voltage than its rating, it conducts current from the anode (positive) to the cathode (negative). This limits the current flow during the transient event and protects the circuit from damage. The device has a specific stand-off voltage that will determine if it starts conducting.

When exposed to a lower voltage than its breakover voltage, the device remains open and does not conduct. It will become part of the circuit if and only if the voltage exceeds the breakover voltage. It will then try to limit the current as it was designed to do until the end of the transient event. At this stage, the SP1002-02JTG reaches its peak power dissipation and then it will auto-restore the circuit.

The SP1002-02JTG is a small size protection device that can be directly inserted on the board without any external circuitry. Because it is a two-terminal device, it is designed to easily fit in most circuits. The device is also designed for long-term reliability, with a minimum working life of 10,000 hours.

The SP1002-02JTG is a very helpful device in protecting circuits from overvoltage transients. Its small size and compact design make it ideal for use in many different applications. It is the perfect solution for circuits exposed to transients, as it can limit current flow and dissipate voltage surges quickly and reliably.
