Littelfuse 1-Element Bi-Directional TVS Diode 400 W, Surface Mount, DO-214 Package SMAJ350CA

Littelfuse SMAJ350CA is a high-performance 1-element bi-directional TVS diode designed specifically to protect sensitive electronic devices from transient voltage spikes such as those caused by lightning and other electrical surges. Featuring a 400 W peak pulse power dissipation rating, this diode offers robust protection while maintaining a compact footprint with its surface mount DO-214 package.

This semiconductor component operates efficiently within a temperature range of -65°C to 150°C, making it suitable for demanding industrial, commercial, and electronic applications. Its bi-directional polarity allows protection in both directions, expanding safety across various circuit designs.

The diode configuration includes a single element with a maximum reverse stand-off voltage of 350 V and a minimum breakdown voltage of 432 V. It exhibits a fast response time of typically under 1.0 picosecond from 0 volts to breakdown voltage for unidirectional types, ensuring rapid clamping action that mitigates transient voltage damage.

The SMAJ350CA integrates features such as low incremental surge resistance, glass passivated junction, low inductance, and high temperature soldering tolerance up to 250 degrees Celsius for 10 seconds at its terminals. It is a halogen-free device optimized for surface mounted applications, helping to maximize board space while providing reliable repetitive surge protection at a duty cycle of 0.01%.

Key physical dimensions include a length of 4.6 mm, width of 2.79 mm, height of 2.08 mm, and it utilizes a 2-pin DO-214 configuration for simple integration. With a maximum reverse leakage current of just 1 μA, it minimizes power losses and ensures efficient circuit protection.
