    Products Detail

    The SMAJ series of transient voltage suppression diodes provide 400W peak pulse power dissipation (10/1000µs waveform) with fast response time (<1.0ps). Features include glass passivated junction, excellent clamping capability, low inductance, and high-temperature reflow soldering compatibility (260°C/40sec). The low-profile DO-214AC (SMA) package optimizes board space and meets MSL Level 1. Devices offer ESD protection (IEC 61000-4-2: 30kV air/contact) and EFT protection (IEC 61000-4-4), with built-in strain relief and matte tin lead-free plating. Halogen-free and RoHS compliant.
