TVS - Diodes are widely used to protect semiconductor devices, computer equipment, control systems, and communication lines from transient voltage surges that occur in normal operation. The SMAJ200E3/TR13 is a low-capacitance, surface-mount device used to protect particularly sensitive high-speed electronic devices from electrical transients. This device is ideal for protecting high-speed communication ports such as USB and FireWire from spikes in the signal lines.

The SMAJ200E3/TR13 is built with a silicon diode chip as the main component. It consists of two terminal pins and is able to clamp transient voltages up to 200 volts and block currents up to 10 A. The device is RoHS compliant and reaches a working temperature range of -55°C to 125°C. The SMAJ200E3/TR13 provides good protection for sensitive electronic components from transients that can occur in lightening storms or with power-supply switching. It also provides an effective short circuit protection for sensitive circuits from surges created by lightning or other sources.

The working principle of the SMAJ200E3/TR13 is based on the principle of diode doping. The diode layer between the two electrode terminals is symmetrically constructed. The diode acts as a voltage reactant where a voltage drop takes place for values higher than the diode\'s breakover voltage. This means any voltage that is above the breakdown voltage is limited to a manageable level. When the application\'s peak voltage or current level exceeds the breakpoint of the diode, the device begins to conduct. It acts as a low impedance path which redirects the overvoltage to ground. This reduces the peak amplitudes and hence protects the circuit from potential damage.

The primary applications for the SMAJ200E3/TR13 are in consumer electronics, automotive electronics, computer and networking equipment, digital cameras, telecom equipment, power supplies, and medical equipment. This device is most commonly found in portable equipment and other electronics that must withstand electrical transients due to power-supply switching. Additionally, this device is also used in high-speed interfaces such as USB, FireWire, HDMI, and DVI.

The SMAJ200E3/TR13 is a convenient device for providing transient protection in a variety of applications. Its robust design ensures reliable protection against short circuits, overvoltage, and electrostatic discharges. It is also easy to component mount and includes integrated protection against short circuits. All these features make it an ideal choice for providing reliable surge protection for sensitive high-speed electronic components.
