The DF3A6.8FU is a transient voltage suppressor (TVS) diode manufactured by Toshiba Semiconductor and Storage. It's designed to protect sensitive electronic components from voltage surges induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. This particular diode offers bidirectional protection, meaning it can suppress voltage spikes in either polarity.

Applications

• Consumer electronics: Protection of I/O ports in smartphones, tablets, and laptops.
• Industrial equipment: Safeguarding communication interfaces in PLCs and other control systems.
• Automotive electronics: Protecting sensitive components in automotive control units (ECUs) from transient voltages.
• Data and signal lines: Protection of USB ports, HDMI interfaces, and other data transmission lines.
• Power supplies: Suppression of voltage spikes in power supply circuits.

Features

• Bidirectional TVS diode: Provides protection against both positive and negative voltage transients.
• Low clamping voltage: Limits the voltage across the protected device to a safe level during a surge event.
• Fast response time: Quickly clamps voltage surges to prevent damage to sensitive components.
• Compact surface-mount package: Allows for easy integration into space-constrained applications.
• Low leakage current: Minimizes power consumption in normal operating conditions.

Benefits

• Enhanced reliability: Protects electronic circuits from damage due to voltage surges, extending the lifespan of the product.
• Reduced downtime: Prevents failures caused by transient voltages, minimizing downtime and repair costs.
• Improved system performance: Ensures stable and reliable operation of electronic systems in harsh environments.
• Compliance with industry standards: Meets relevant ESD and surge protection standards.
• Cost-effective solution: Provides a simple and affordable way to protect electronic circuits from voltage surges.

Additional Details

The DF3A6.8FU has a standoff voltage of 6.8V and a clamping voltage of typically around 11V at a specific test current. Its peak pulse power dissipation is rated to handle transient events. The package type is typically a small surface-mount package like SOD-323. Consult the datasheet for specific electrical characteristics, surge current ratings, and package dimensions.

As this is an End-Of-Life (EOL) product, it may be difficult to source and alternative parts should be considered for new designs.
