    Products Detail

    The SMF series is a surface-mount TVS diode series designed for transient voltage protection. It offers 200W peak pulse power dissipation (10/1000µs waveform) and features a compact SOD-123FL package that is 50% smaller in footprint compared to SMA package, with a low profile of 1.1mm. The series includes both uni-directional and bi-directional options, with fast response time typically less than 1.0ns. It is RoHS compliant, halogen-free, and suitable for surface-mounted applications to optimize board space.

    Key Features

    • 200W peak pulse power (10/1000µs waveform), EFT protection per IEC 61000-4-4, Fast response time <1.0ns, SOD-123FL package with 1.1mm height, Glass passivated junction, Built-in strain relief, Low inductance, Excellent clamping capability, UL 94 V-0 flammability rating, Surface mount optimized, MSL Level 1, 260°C peak reflow, Matte tin lead-free plating, Halogen-free and RoHS compliant, ESD protection per IEC 61000-4-2 (30kV air/contact), Uni-directional and bi-directional options
