Littelfuse specializes in transient voltage suppression (TVS) diodes, which are designed to protect semiconductors from damage due to transient voltages.

Low incremental surge resistance
Unidirectional and Bidirectional polarities available
Reverse standoff voltages range from 5V to 495V
Peak power ratings from 400W to 30kW
High current protection available - 1kA, 3kA, 6kA, 10kA and 15kA

The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events

Halogen-Free
For surface mounted applications in order to optimize board space
Low profile package
Built-in strain relief
Glass passivated junction
Low Inductance
Excellent clamping capability
Repetition Rate (duty cycle): 0.01%
Fast response time: typically less than 1.0ps from 0 Volts to V(BR) for unidirectional types.
Typical IR less than 1mA above 10V
High temperature soldering: 250 degrees C/10 seconds at terminals
