VBT3080C-M3/4W is a high current transient voltage suppressor array, consisting of four silicon avalanche diodes. It is designed specifically to protect sensitive devices such as microcontrollers and other integrated circuits against transient over-voltages caused by electrostatic discharge (ESD), electrical fast transient (EFT), and other noisy phenomena. Its operating temperature range is from -55°C to 175°C and it has a storage (maximum) junction temperature of -65°C to 225°C.

As its name suggests, the VBT3080C-M3/4W is a high current transient voltage suppressor array, specifically designed to protect sensitive devices from overvoltage. It is capable of withstanding infrequent voltage transients up to 30V and a maximum continuous operating voltage of 24V. It also has a reverse breakdown voltage of 30V and can handle a maximum peak pulse current of 80A (for a 10x1000μs pulse).

The VBT3080C-M3/4W also has an integrated crowbar circuit to protect devices from overcurrent conditions. The crowbar circuit activates when the protected device regards the current exceeding its rated current, thus ceasing its current flow. This protection feature is beneficial in providing a safe and secure power supply.

The working principle of the VBT3080C-M3/4W is quite simple. It basically works like a circuit breaker by stopping the current flow when an excessive amount of current is sent to the protected device. This is done by using an integrated crowbar circuit which engages when the protected device detects an overcurrent situation. In this case, the array of diodes activates its avalanche functions and quickly absorbs the energy from the overcurrent, thus limiting the amount of energy sent to the protected device. This helps protect the device from damage.

The VBT3080C-M3/4W is a vital component for anyone looking to protect their electronic devices from transient overvoltage. Diodes in the array allow for quick response to voltage spikes and transients, providing a safe and secure power supply. It can be used in a variety of specialized applications, such as automotive, consumer electronics, and medical equipment, requiring reliable protection.
