BZW04-110BHE3/54 Circuit Protection

TVS diodes are a type of unidirectional semiconductor device that protects sensitive systems from high electrical voltages. The BZW04-110BHE3/54 is a TVS diode specifically designed to offer protection against both overvoltages and electrostatic discharge. As such, this diode is of particular interest to electrical engineers who need to protect their circuits from destructive voltage spikes or surges.

The BZW04-110BHE3/54 is a member of the BZW04 series of TVS diodes. It has a reverse breakdown voltage of 110V at a reverse current of up to 1A. This diode also features a low capacitance of 4pF typical, so it does not interfere with high-speed digital signals. The device has a peak pulse power of 400W, making it suitable for protecting against voltage surges with energy levels up to 400 psi.

The BZW04-110BHE3/54 is most suitable for use in automotive and industrial applications. It can be used to protect electrical components from the large voltage spikes that often occur during normal operation. This diode is also ideal for use in low-voltage motor control circuits, as it can help protect against voltage surges that may otherwise damage motors and other components. In addition, the diode is often used as a shock absorber in automation, robotics, and electrical vehicle applications.

The working principle of the BZW04-110BHE3/54 is governed by the fact that it is a unidirectional device. Current can only flow in one direction through the diode, which means that voltage spikes above the reverse breakdown voltage will be clamped to a level determined by the device. This helps protect downstream components from destructive surge currents and voltage spikes.

The device’s ESD protection is also based on its unidirectional nature. If an electrostatic discharge is applied to the diode, the current will be limited due to the diode\'s reverse breakdown voltage. This current limiting action reduces the risk of damage to sensitive components that could normally be affected by electrostatic discharge.

The BZW04-110BHE3/54 is a versatile TVS diode that offers reliable protection against voltage surges and electrostatic discharges. Its combination of low capacitance and high peak pulse power make it ideal for use in a range of automotive and industrial applications.
