    Products Detail

    The SMAJ series is a surface-mount transient voltage suppression diode series with 400W peak pulse power capability at 10/1000µs waveform. It features fast response time (typically <1.0ps), glass passivated junction, excellent clamping capability, low inductance, and high-temperature reflow soldering compatibility (260°C/40sec). Available in both uni-directional and bi-directional configurations, these diodes offer low-profile packaging optimized for space-constrained applications. The series meets MSL Level 1, includes built-in strain relief, and provides ESD/EFT protection per IEC standards. It is halogen-free, RoHS compliant, and uses matte tin lead-free plating.
