Transient voltage suppressors (TVS) are used to protect electrical circuits from transient spikes voltage that can cause damage to components. These devices work by absorbing the energy from the spikes and dissipating it as heat. The VBUS05L1-DD1-G-08 is a TVS diode specifically designed to protect automotive circuits such as infotainment systems, airbag control units, or engine control modules from destructive and malfuctioning transients.

The VBUS05L1-DD1-G-08 features an ESD rating of 22 kilovolts and a maximum peak pulse power rating of 600 watts. It is constructed of two back-to-back, low voltage diodes that protect against transients up to 8 volts. The device also provides robust thermal protection with a short circuit clamping voltage of 5.6 volts. The VBUS05L1-DD1-G-08 is rated to operate over an operating temperature range of -55 C to +125C.

In its normal condition, the VBUS05L1-DD1-G-08 is non-conductive, allowing current to pass through uninterrupted. When a transient voltage exceeds its rated breakdown voltage of 8 V, the device’s PN junction is triggered, which flips the internal switch to a highly conductive state. This causes the VBUS05L1-DD1-G-08 to absorb the energy from the transient and dissipate the energy as heat. As the transient voltage falls back to its normal state, the device returns to its non-conductive state, restoring the normal flow of current once again.

The VBUS05L1-DD1-G-08 is ideal for use in automotive electronics systems because of its robust thermal protection, low ESD rating, and wide operating temperature range. In addition, its small size and low profile design make it ideal for tight, confined spaces. The device is available in both surface mount package (SOT-23) and axial leaded package.

In summary, the VBUS05L1-DD1-G-08 TVS diode provides robust protection for automotive circuits against transients of up to 8 volts. With its ESD rating of 22 kilovolts, maximum peak pulse power rating of 600 watts, and thermal protection, it is perfect for use in automotive electronics systems. It is available in both surface mount and axial leaded packages and is ideal for use in tight, confined spaces.
