TVS diode, or Transient Voltage Suppressor diode, is a component of semiconductor technology, which works as a protective device against overvoltage or overcurrents. The TVS diodes are very helpful in protecting the sensitive electronic components from the destructive effects of these electrical surges. A BZT03D120-TAP diode is a variant of TVS diode with high surge ratings. It is a unidirectional transient voltage suppressor designed for overvoltage protection in communications and networking applications.

A BZT03D120-TAP diode is a three-terminal device that can be connected in a BZXV arrangement for bidirectional overvoltage protection applications. It is a low capacitance component and thus able to handle high surge ratings. The maximum transference voltage is 200V with a max power dissipation of 1.5 watts. The BZT03D120-TAP can handle peak pulse power up to 500 watts. The forward standing voltage of the device is 380 mV at 1A.

The application of the BZT03D120-TAP diode can be found in computers, mobile phones, PDAs, and other telecom and networking applications. It is used mainly for protecting overvoltage related components such as processors, DRAMs, transistors, capacitors, and more. The device also helps to protect sensitive electronic components from strong electrical surges.

The working principle of the BZT03D120-TAP diode is based on avalanche divider technology. Essentially, when a surge occurs, the avalanche divider is activated, creating an open path for the extra current to dissipate, thus protecting the sensitive components. The device helps in reducing the limited current in the path and prevents it from damaging the circuit. It works as a protective ‘spark gap’ and thus prevents any overvoltage or overcurrents.

The BZT03D120-TAP diode is a very efficient and reliable component that is widely used in a variety of applications that require reliable voltage protection. It is able to handle high surge ratings and offers excellent overvoltage protection. This makes it a perfect choice for telecommunications, computers, and networking applications.
