TVS - Diodes

Transient Voltage Suppressors (TVS) diodes are used to protect a device from voltage spikes. They are commonly found in GSM/GPRS receivers, in power supplies, and in automotive and industrial systems. The BZG04-15TR3 is a bi-directional unidirectional TVS diode with an operating voltage range of 15V-100V.

Application Field

The BZG04-15TR3 is designed to protect any system or device from overvoltage transients. It can be used in ASIC circuits and other components, such as gate drivers and driver synchronized circuits. It is also suitable for automotive and industrial applications, due to its wide operating voltage range, and can be used as an ESD protection device as well.

Working Principle

The BZG04-15TR3 is a unidirectional, bidirectional TVS diode which works by controlling the movement of electrons. When a voltage transient exceeds the normal operating voltage, the diode becomes conductive and the excess voltage is directed to ground. This prevents the voltage from reaching the device, thus protecting it from any potential damage.

The diode also works in reverse, where it will act as a clamp for a voltage surge. When the voltage is below the normal operating voltage, the diode stays open. This helps protect the device from short circuit and overvoltage conditions, and helps to avoid potential damage.

Conclusion

The BZG04-15TR3 is an effective, low-cost way to protect any system or device from overvoltage transients. It is suitable for use in applications ranging from automotive and industrial to ASIC circuits and gate drivers. With its reverse operation and low voltage leakage, the BZG04-15TR3 is a reliable, efficient, and cost-effective way to protect electrical components from surges.
