Product Details

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

Halogen free
For surface mount applications in order to optimize board space
