    Products Detail

    The SMBJ series is a family of 600W transient voltage suppression diodes designed for surface mount applications. They provide protection against voltage transients with fast response time, excellent clamping capability, and built-in strain relief. Available in uni-directional and bi-directional configurations, these devices feature low profile packaging optimized for board space, matte tin lead-free plating, and meet MSL Level 1. They are halogen free, RoHS compliant, and suitable for high-temperature reflow soldering.

    Key Features

    • 600W peak pulse power capability at 10/1000μs waveform
    • Built-in strain relief
    • Fast response time: typically less than 1.0ps
    • Excellent clamping capability
    • High temperature reflow soldering guaranteed: 260°C/40sec
    • Low incremental surge resistance
    • V_BR temperature compensation
    • Surface mounted applications optimize board space
    • Plastic package flammability rated V-0 per UL-94
    • Typical failure mode is short circuit
    • MSL Level 1 per J-STD-020
    • Whisker test conducted per JEDEC JESD201A
    • Matte tin lead-free plated
    • Halogen free and RoHS compliant
