Littelfuse SD05-01FTG, Uni-Directional TVS Diode Array, 2-Pin SOD-323

Littelfuse SD-C Series 450W Discrete Bidirectional 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 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

Low dynamic resistance of only 0.5Ω
Low leakage of 1μA max.
No inherent wear-out factor
SOD-323 package fits existing 0805 PCB footprints
Buttons/keypads, switches, DC power ports, and various other low-speed I/Os
Point-of-sale terminals, test equipment or instrumentation, medical equipment, desktop/notebook computers, servers, computer peripherals, etc.
