BYV15-TAP Application Field and Working Principle

BYV15-TAP is a single-phase, unidirectional, silicon, fast-acting avalanche-recovery Rectifier DIODE, developed by TO-220AB case with a ceramic insulator terminal. It is designed to provide protection to sensitive electronic equipment.

Application Field

BYV15-TAP is applicable in many fields that are exposed to over-voltage and lightning strikes, such as industrial and commercial lighting system, electricity generation, power transmission, and communication systems. Moreover, it can be used to protect battery charging systems and has built-in thermal protection, which helps to prevent over-charging. Additionally, it can be used to protect logic control, gate control, and gate drivers.

Working Principle

The BYV15-TAP is a high-performance constant voltage circuit protection device which is able to detect over-voltage and then quickly respond, withstanding step surge up to 95A (1.2/50μs). Its unique working principle is based on the rapid avalanche breakdown of the diode. In normal working conditions, the diode is in a reverse-biased state and behaves like an open circuit, allowing no current to flow. However, when a high voltage is applied to the diode, it goes into the reverse breakdown or "avalanche" region, the voltage-current characteristics become nonlinear with the resistance decreases rapidly and the current flows through the diode.

When an over-voltage event is detected, the BYV15-TAP diode closes the circuit and conducts current, guiding the high voltage away from sensitive equipment. After the voltage surge has been diverted, the diode switches back to the reverse-biased state, preventing further damage. The diode’s fast response time enables it to protect sensitive components from the destructive effects of voltage surges.

Conclusion

In conclusion, the BYV15-TAP is a single-phase, unidirectional, silicon, fast-acting avalanche-recovery rectifier diode developed by TO-220AB case with a ceramic insulator terminal. It is designed to provide protection to sensitive electronic equipment, and has a wide range of applications across many sectors. Its ability to quickly switch between reverse-biased and forward-biased states allows it to protect sensitive components in the event of an over-voltage surge.
