Products within this series have been qualified to AEC-Q101 and are appropriate for use in Automotive applications.
Littelfuse SD Series 450W Discrete Unidirectional TVS Diodes are designed to protect against destructive electrostatic discharges (ESD) and lightning-induced surge currents. These fast-acting TVS Diodes are ideal for replacing 0805 size multilayer varistors (MLVs) in low speed and DC applications because they can safely absorb repetitive ESD strikes at ±30kV without performance degradation and safely dissipate up to 30A of surge current. Their low dynamic resistance provides up to a 50 percent reduction in clamping voltage compared to competing technologies.
- ESD: IEC61000-4-2, ±30kV contact discharge
- Lightning: IEC61000-4-5, 30A (tP=8/20?s)
- Low dynamic resistance
- No inherent wear-out factor
- SOD-323 package fits inside existing 0805 PCB footprints
- AEC-Q101 qualified
