BZA408B,115 Circuit Protection

TVS (Transient Voltage Suppressors) are devices that’s mainly used for protecting against electrical surges, especially those caused by lightning, and other transient voltages that may exceed the power rating of components in a system. The BZA408B,115 device is a TVS diode, which is a common form of the TVS, and is mainly used in automotive power lines, as it has the capability to limit very high peak voltage and energy.

The BZA408B,115 is a 400V, 1200W peak pulse power device designed for suppressing transients in automotive power lines. It is an unidirectional diode with an ultra-small form factor, making it easier to install in tight spaces. It also features a low-clamping voltage which helps reduce any additional power dissipation when surge voltages occur. This device provides ESD (electrostatic discharge) protection and is EMI (electromagnetic interference) compatible.

The device is constructed from a silicon epitaxial planar diode with a special encoding that helps to reduce power dissipation. It has a wire-bonded metallized ESD protection diode for protection against electrostatic discharges of up to 15kV and also has an adhesion structure for vibration and temperature stability. The package type of the device is a DO-214AC (JEDEC) with a lead-free termination. The device has a maximum junction-to-case thermal resistance of 540°C/W.

The principle behind the BZA408B,115 is the same as the other common TVS diodes. When a transient voltage is applied to the device, the silicon p-n junction is reverse-biased, which creates a barrier that blocks any current from flowing through it. This process helps to clamp the voltage and absorb the energy from any transients, thus protecting the device from over-voltage conditions.

The BZA408B,115 is mainly used in automotive power lines, as it can protect the components against extremely high peak voltages and energy. It can also be used in general consumer electronics such as TVs, computers, and other appliances. The device is also popular in industrial applications, as it can provide reliable protection against spikes and surges.

The BZA408B,115 is a reliable and versatile device, and is a great option for protection against transient voltages. It is well suited for a variety of applications, as it is small and compact, and features low-clamping voltage, ESD protection, and EMI compatibility. The device is a great choice for systems that need reliable protection against transient surges.
