Introduction

Transient Voltage Suppressor Diodes (TVS-Diodes), also known as "transient voltage suppressors" or TVSs, are a type of diode designed specifically for protecting electrical systems from transient over-voltage events. TVS-Diodes are an important element in the protection of sensitive electronic hardware components from transient voltage spikes. The specific transient voltage suppressor discussed in this article is the PESD2V0Y1BSFYL, manufactured by NXP Semiconductors.

Application Field

PESD2V0Y1BSFYL TVS-Diodes are designed for the protection of voltage sensitive components, such as microcontrollers, from voltage over-voltage transients. Common applications include power supply protection, motor control circuits, and computer peripherals. The devices are also suitable for use in home appliances and automotive electronic circuits.

Working Principle

The PESD2V0Y1BSFYL TVS-Diode uses a two-terminal device incorporating two Zener diodes connected in series. The two diodes provide a voltage clamp to regulate the maximum voltage which can pass through the device. If the input voltage exceeds a certain limit, typically due to an over-voltage transient, the device will conduct the excess voltage away, protecting the circuit from damage. The two Zener diodes are connected in series to provide a wide operating voltage range.

The PESD2V0Y1BSFYL TVS-Diode also includes an 8.2nF capacitor which is connected across the two diodes. The capacitor helps to reduce the peak voltage, providing extra protection to the circuit. The device has been designed for use in low voltage applications, and provides protection up to 6V.

Conclusion

The PESD2V0Y1BSFYL TVS-Diode is a two-terminal device designed for use in low voltage applications, providing protection up to 6V. It works by providing a voltage clamp to regulate the maximum voltage which can pass through the device. The device also includes an 8.2nF capacitor which helps to reduce the peak voltage, providing extra protection for the circuit. The PESD2V0Y1BSFYL is suitable for use in a wide range of applications, including power supply protection, motor control circuits, and computer peripherals.
