TVS3301DRBR Bidirectional TVS Diode with Low Clamping Voltage and Fast Response Time for Surge Protection

1. Core Functionality

• Bidirectional Surge Protection: Provides symmetrical clamping capability for both positive and negative transient voltages, effectively suppressing ESD, electrical fast transients (EFT), and lightning-induced surges.
• Low Clamping Voltage: Delivers a low maximum clamping voltage under surge conditions, minimizing voltage overshoot and protecting downstream components (e.g., ICs, sensors, communication interfaces) from damage.
• Fast Response Time: Features sub-nanosecond response speed (<1 ns) to transient events, ensuring rapid activation before damaging voltage levels reach sensitive circuitry.
• High Surge Handling Capacity: Offers robust peak pulse power dissipation, capable of withstanding repetitive transient pulses without performance degradation, suitable for harsh industrial and consumer electronics environments.
• Compact Surface-Mount Package: Utilizes a small SOD-123 package (DRBR suffix), enabling space-saving integration in portable devices, automotive electronics, and IoT modules.
