Littelfuse Uni-Directional TVS Diode 400 W 2-Pin DO-214 SMAJ10A

The Littelfuse SMAJ10A uni-directional TVS diode is engineered for high-reliability transient voltage suppression in electronic circuits. Featuring a surface-mount DO-214 package, this diode is ideal for compact PCB designs in industrial, laboratory, and commercial applications.

With a peak pulse power dissipation of 400 W, the SMAJ10A diode provides robust protection against unpredictable surges, such as those caused by lightning strikes or switching events. The uni-directional configuration enables precise circuit protection, particularly for sensitive semiconductors prone to overvoltage.

Key electrical parameters include a minimum breakdown voltage of 12.3 V, clamping voltage of 17 V, and maximum reverse stand-off voltage of 10 V. The component supports a maximum peak pulse current of 23.5 A and features a low maximum reverse leakage current of 5 μA, ensuring reliability across cycles.

The glass-passivated junction, coupled with low incremental surge resistance and excellent clamping capability, maximizes response time, typically less than 1.0 ps. The built-in strain relief and halogen-free construction enhance longevity and compliance with environmental standards.

Its low profile and surface-mount form factor ensure an efficient board layout, while operating temperatures range from -65°C to 150°C, suitable for demanding industrial or commercial environments. High temperature soldering is supported up to 250°C for 10 seconds at terminals, and ESD protection is integrated to further safeguard circuit integrity.

The Littelfuse SMAJ10A is widely applied in the protection of medical equipment, communication devices, industrial control panels, and other electronics requiring reliable protection against voltage transients.

Provides protection against voltage surges and transient events. Peak pulse power dissipation up to 400 W under transient conditions. Uni-directional design supports precise handling of surges. Operates with a clamping voltage of 17 V to effectively divert excess energy.

Surface-mount DO-214 package optimizes PCB space and enables easy integration. Supports maximum peak pulse current of 23.5 A for enhanced surge capability. Suitable for protecting sensitive components in industrial and commercial electronics.
