DF2B7AFS,L3M Circuit Protection

TVS - Diodes

TVS-Diodes, also known as Transient Voltage Suppression Diodes, are electronic components that are used to protect against high-voltage, high-energy spikes. TVS-Diodes are designed to protect electronic equipment from damage caused by electrostatic discharge (ESD) or other transient power events. The DF2B7AFS,L3M model is one type of TVS-Diodes.

Application Field

The DF2B7AFS,L3M is mainly used in automotive, consumer electronics, industrial and medical applications. It is a low capacitance ESD protection diode that is designed to provide a robust protection. This TVS-Diode is a 2.5 Volt-bidirectional diode that can handle peak pulse power up to 400Watts. It provides excellent clamping capabilities that can be used in environments where ESD and electrical over-stress have to be dealt with in a reliable manner.

Working Principle

TVS-Diodes are deviced made of materials like silicon carbide, zinc oxide, aluminum oxide andgallium arsenide. The DF2B7AFS,L3M model is based on a unique multiple discretediodes structure which offers enhanced ESD immunity up to 32 kilovolts. When a high-voltage transient is applied, the diode is turned on and the current is conducted through it, providing protection to the electronic component. This process only occurs with high voltage peaks and does not affect the normal operation of the circuit.

The DF2B7AFS,L3M offers moderate ESD protection while maintaining a low capacitance. This allows it to be broadly applicable across a wide range of applications without affecting the signal integrity of the circuit due to its low capacitance and low series inductance. The low trimming resistance tolerance of ±5% ensures a reliable and consistent performance.

Benefits

The main benefit of using TVS-Diodes is that they protect valuable electronic components from damage caused by ESD events. The DF2B7AFS,L3M model provides robust protection to sensitive components without affecting the signal integrity of the circuit. The low capacitance design will not affect the signal integrity, and the low series inductance ensures a low voltage buildup. Additionally, this TVS-Diode is suitable for a large range of applications and offers high reliability in harsh environments.
