SMF Ultra-Low-Voltage TVS Diodes: SMF2.5/SMF3.0/SMF4.0
Littelfuse TVS diodes provide advanced surface-mount protection for sensitive electronic equipment
The Littelfuse SMF2.5, SMF3.0, and SMF4.0 series ultra-low-voltage TVS diodes are designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. These diodes offer a peak pulse power dissipation of 200 W at a 10 µs/1,000 µs waveform, making them ideal for safeguarding portable components, hard drives, notebooks, VCC buses, POS terminals, solid-state drives (SSD), power supplies, monitors, and other consumer applications. Housed in a low-profile SOD-123FL package, these TVS diodes optimize board space while providing robust protection. They feature low dynamic resistance, high surge capability, and are compliant with RoHS and halogen-free standards. Additionally, they are recognized under UL 497B as isolated loop circuit protectors, ensuring reliable performance in various environmental conditions.
