TVS (Transient Voltage Suppressors) diodes are one of the most widely used diode types in a variety of applications. The BZW04-15HR0G is a commonly used TVS diode that provides protection against voltage transient spikes, electrostatic discharge (ESD) and oscillatory transients. It is designed to meet the IEC 61000-4-2 ESD requirements. The BZW04-15HR0G diode also offers the advantage of a wide operating temperature range, making it ideal for use in a variety of industrial, automotive and consumer applications.

Applications of BZW04-15HR0G

The BZW04-15HR0G diode is mainly used for the protection of electronic circuits from voltage transients. It is used in important automotive electronics, such as ECUs, ICs, and sensors, as well as for the protection of electronic processes, such as machine control systems. It is also commonly used in consumer electronics, such as media players, cellular phones, and other portable devices. It has even been used in military applications for the protection of sensitive equipment.

Working Principle

The BZW04-15HR0G diode is a bi-directional, purely electronic element which acts as an electrical clamp to suppress transients. It works by detecting the presence of a voltage transient, then rapidly restricting current flow in the positive and negative directions to protect the circuit. It is an important component in successfully protecting an electronic circuit from an excessive transient surge.

The working principle of the BZW04-15HR0G is based on the device’s low on-state voltage, high peak surge suppression capability, and low clamping voltage. When transients are present, the device begins to conduct current and move electrons from the anode to the cathode, increasing the voltage of the cathode side and thereby providing protection for the circuit. At the same time, it decreases the voltage of the anode side to match the threshold voltage, which reduces the forward voltage of the diode in the opposite direction.

Conclusion

The BZW04-15HR0G diode is a widely used TVS diode that is designed for the protection of electronic circuits from voltage transients, ESD, and oscillatory transients. Its wide operating temperature range and low clamping voltage make it a good choice for a variety of applications, including automotive, industrial, and consumer electronics. Its working principle is based on the device\'s low on-state voltage, high peak surge suppression capability, and low clamping voltage.
