TVS - Diodes
TVS diodes, also known as Transient Voltage Suppressor diodes, are unidirectional semiconductor devices that can be applied in electronics to protect them against electrical overstress (EOS) or electrostatic discharge (ESD). The BZA962AVL,115 is a type of TVS diode, specially designed to reduce overvoltage transients, by clamping down on excess voltage and protecting the internal components of the electronics.Application Field
The applications of the BZA962AVL,115 are quite versatile as it is suitable to be used in several industries, such as consumer electronics, the telecommunication and automotive industries. The low capacitance of this type of TVS diode makes it ideal for use in consumer electronic products, since these use high-speed digital switching and require devices with minimal capacitance. This diode is also commonly used in automotive applications requiring high voltage protection, such as power windows, electronic systems, and audio amplifiers.Working Principle
As a bidirectional TVS diode, the BZA962AVL,115 is specially designed to dissipate both positive and negative transits. Its protection circuit includes a series protection resistor and clamping diodes connectedto the anodes. Its working mechanism is based on the protection resistor, the two protection diodes and the parasitic capacitance of the chip that work in tandem to absorb the excess energy of the over voltage transient and limit the peak voltage.The integrated protection resistor limits the inrushcurrent during the transient event, thus allowing the protection diodes to clamp the excessive voltage. The two integrated protection diodes have different breakdown voltages, ensuring that the voltage is kept below a safe working level throughout the pulse.The typified capacitance also plays a role in the TVS diode\'s protection circuit. The capacitance is formed when the area of the chip exposed to the ESD pulses grows; the capacitance helps reduce the voltage by the time it reaches the internal components of the electronics, creating a soft clamping action.Conclusion
In conclusion, the BZA962AVL,115 is a type of TVS diode that is designed to reduce overvoltage transients. Its integrated protection components, consisting of the protection resistor, the two clamping diodes and its parasitical capacitance, work together to absorb excessive voltage and protect the internal components of the electronics. This type of TVS diode is suitable for use in industries such as consumer electronics, the telecommunication and automotive industries.
