TVS-Diodes, also known as transil-diodes or Transient Voltage Suppressors (TVS) diodes, are used to protect circuits against damaging levels of electrical transients, voltages, and currents. The SubMiniature size B (SMBJ) series is 8.0E3 in size and offers excellent performance in surge protection applications. It is capable of protecting against electrostatic discharges (ESD) of up to 2000 V and transients up to 8kV.

A TVS Diode consists of a highly doped silicon semiconductor junction and functions as a one-way current valve. This type of diode works by allowing electricity to freely flow through it in one direction while blocking the flow in the other direction. When a transient voltage or current is applied, the diode allows an avalanche breakdown current to flow through the junction. This breakdown current is limited and restricted within the junction, thus protecting the circuit.

The SMBJ8.0E3 series is an ideal solution for protection of sensitive electronics against electrostatic discharges (ESDs), transients, and voltage spikes due to Inductive load switching, electrostatic discharge, lightning, and other transient events. It has a low capacitance of 7pF and is designed specifically to withstand surface-mounted applications with minimum size and without additional components. Additionally, the SMBJ8.0E3 diode provides high transient suppression capability with an insulation voltage rating of up to 8000V RMS (minimum).

The SMBJ8.0E3 TVS Diode can be used in multiple applications, such as line ESD protection, DC-DC buck/boost converters, voltage regulators, switching supplies, automotive, aerospace, communication systems, and military systems, to name a few. It has a low on-state voltage drop of 1.3V max at 6A and a breakdown voltage of between 7.5V to 8.3V, depending on the device variant. This makes it an ideal choice for protecting low voltage circuits against high voltage and high current transients.

In summary, the SMBJ8.0E3 diode from the TVS Diodes family offers a compact solution for protecting sensitive electronics against ESDs, transients, and voltage spikes. It has a small form factor, allowing it to fit into applications with space constraints. Additionally, it can withstand high voltages and currents, making it the perfect choice for applications such as automotive, communication systems, military systems, and aerospace.
