Littelfuse 1-Element Uni-Directional TVS Diode 400 W, 2-Pin DO-214 SMAJ100A

The Littelfuse SMAJ100A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode specifically engineered to protect sensitive electronic equipment from transient voltage spikes such as those induced by lightning and switching events. This surface mount device comes in a compact 2-pin DO-214 package measuring 4.6 mm length, 2.79 mm width, and 2.08 mm height, optimizing space on printed circuit boards.

With a peak pulse power dissipation rating of 400 W and a maximum peak pulse current of 2.5 A, it offers robust protection under demanding conditions. Its minimum breakdown voltage is specified at 123 V, with a typical clamping voltage of 162 V, ensuring effective distraction of transient surges. The diode features a maximum reverse stand-off voltage of 100 V, appropriate for various industrial and commercial electronics.

Designed to operate reliably from -65°C up to 150°C, this Littelfuse TVS diode benefits applications in industrial, automotive, power supply, and communication device environments. The fast response time, typically less than 1 picosecond, minimizes potential damage from electrical overstress. Constructed with a glass passivated junction and low inductance, the component provides excellent clamping capability with high surge current tolerance.

Additional features include halogen-free material construction for environmental compliance and high-temperature soldering tolerance up to 250°C for 10 seconds at terminals, facilitating assembly and maintenance processes.
