TVS - Diodes (Transient Voltage Suppressors (TVS) Diodes) are a semiconductor device that acts to protect other electronic components from electrical overstress (EOS). TVS Diodes are used to dampen high frequency power glitches and are designed to limit overvoltage transients from entering the protected devices. The BZG04-56TR3 is among the most popular TVS Diodes in the marketplace.

At its core, the BZG04-56TR3 is basically an avalanche breakdown diode (ABD) configured in a coil-style geometry and intended for use as an ESD protector. The diode is designed to “clamp” fast rising input transients, such as those cases when an ESD event occurs. The ABD is configured in a coil-style geometry and the Schottky junction is configured in parallel to the coil. This architecture provides a very high surge current capability, which enables maximum protection for downstream components.

In terms of its application field, the BZG04-56TR3 is generally used to protect consumer electronics, such as personal computers, tablets, and mobile phones, from electrical overstress. The BZG04-56TR3 has an operational voltage of 8V, a controlled turn-on time of 9ns, a pulse power rating of 1.2W, a junction capacitance of 5pF, and a temperature coefficient of -0.14%. These specs make it ideal for protecting sensitive electronic components from high voltage transients without causing any noticeable side effects.

In terms of its working principle, the BZG04-56TR3 operates based on the avalanche breakdown process. When the reverse bias voltage applied across the diode exceeds a certain threshold, an avalanche breakdown process takes place. This results in the current flow through the diode to increase exponentially, thus resulting in the voltage being clamped. This, in turn, prevents excessive voltage from entering into the protected electronic component.

In summary, the BZG04-56TR3 is a Transient Voltage Suppressor (TVS) diode used for protecting electronic components from electrical overstress. Its high surge current capability makes it ideal for protecting sensitive components from high voltage transients without causing any noticeable side effects. The diode operates based on the avalanche breakdown process, wherein a reverse bias voltage exceeding a certain threshold will cause the current flow through the diode to increase exponentially, thus resulting in the clamping of the voltage.
