LXES15AAA1-133

LXES15AAA1-133 is a TVS - Diodes type made for protection against high voltage surges.

In general, a TVS - Diode is a two-lead device that is designed to protect a circuit from excessive voltages. They come in various sizes and voltage ratings, such as the LXES15AAA1-133. As an active component, a TVS diode has two modes of operation: breakdown and forward.

Application Field

The LXES15AAA1-133 is suitable for protection of LS-Bus Transient Surges, providing enhanced over-voltage protection and significantly increasing system reliability. It can be used in cars, power converters, wireless charging systems, battery operated electronics and other applications.

This particular TVS diode has a voltage clamping level of 15V, with a peak pulse power of 200W, and a capacitance of 2.9pF. It is also rated to work at a temperature range from -55°C to +175°C, making it highly robust and reliable even in extreme temperatures.

Working Principle

In operation, a TVS diode\'s main mechanism is the breakdown effect. It is the ability to switch from a low resistance state to a high resistance state when there is a high voltage surge, thus protecting the circuit from electrical over-voltage.

In the low resistance state, the diode is in the forward biasing mode. This allows for a potential difference to be applied across the two leads of the diode creating a flow of current. When an over-voltage is applied to the diode, the breakdown effect occurs and the diode switches to a high resistance state which blocks current flow.

Once the excess voltage has been dissipated, the diode returns to the low resistance state once again. This mechanism repeats itself as necessary, protecting the circuit from excessive voltages.

The LXES15AAA1-133 is designed to have a fast switching speed which helps to reduce the amount of power that can be transferred through the diode. It also has low leakage and low capacitance ratings, which helps ensure that it will not cause any undesired interference with the electrical signals.

In summary, the LXES15AAA1-133 TVS - Diode is designed for protection against high voltage surges, providing enhanced over-voltage protection and system reliability in various automotive, power converter, wireless charging systems, battery operated electronics and other applications.
