SD and SD-C Series SPA® TVS Diodes - Lightnin

The SD and SD-C Series 450 W discrete unidirectional and bidirectional TVS diodes from Littelfuse are designed to protect against destructive electrostatic discharges (ESD) and lightning-induced surge currents. These fast-acting TVS diodes are ideal for replacing multilayer varistors (MLVs) in low-speed and DC applications because they can safely absorb repetitive ESD strikes at ±30 kV without performance degradation and safely dissipate up to 30 A of surge current. Their low dynamic resistance provides up to a 50% reduction in clamping voltage compared to competing technologies.
