Transient-voltage-suppression (TVS) diodes are electronic components that protect against transient voltage spikes. These electrical surges occur when current is transferred between different circuits, or when static electricity is discharged. The BZG04-110TR is a unidirectional transient-voltage-suppressor (TVS) diode used to protect circuits from electrical transients caused by lightning, inductive load switching, and electrostatic discharge.

The BZG04-110TR is a bi-directional TVS diode with a unidirectional “breakdown” voltage near 115V. It is housed in an SOT-23 surface mount package size, or “footprint”, and its maximum power consumption is 65 mW. Its surge current capability is rated at 448 W, and its reverse clamping voltage is 12 V. Its operating temperature range is -40 to +85 °C, and it has a storage temperature range of -65 to +150 °C.

The BZG04-110TR\'s application fields range from portable devices such as laptops, tablets, and mobile phones, to high-voltage electrical systems found in industrial and automotive use. It is ideal for applications where transients are expected to be of short duration and have a peak signal voltage of up to 115V.

The TVS diode’s working principle is based on the characteristics of a diode, which is an electrical component that allows current to flow in one direction only. When a transient voltage spike occurs, the diode will conduct current and “clamp” the voltage spike down to a level that is safe for the device being protected. This clamped voltage is referred to as the “breakdown” voltage, and is typically around 115V.

The BZG04-110TR TVS diode also utilizes a “snubber” network to help reduce ringing in the power system by dampening voltage spikes during high switching transitions. The snubber network consists of an RC circuit (Resistor-Capacitor) that absorbs the ringing.

The BZG04-110TR is a robust, reliable, and cost-effective way to protect high-voltage electrical systems and portable devices from unwanted electrical transients caused by various sources. It is well suited for use in a variety of applications and is capable of providing effective protection against voltage spikes and surges caused by lightning, inductive load switching, and electrostatic discharge.
