TVS Diodes Offer Superior Clamping

Littelfuse, Inc. introduced the SD and SD-C Series 450 W Discrete Unidirectional and Bidirectional TVS Diodes, the latest additions to its line of TVS Diode Arrays (SPA® Diodes). 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 percent reduction in clamping voltage compared to competing technologies, making them ideal for protecting buttons, switches, power ports, and other various low-speed I/Os in automotive electronics, test equipment, point-of-sale terminals, ultrabooks, servers and medical equipment.

The SD and SD-C Series TVS Diode Arrays offer these key benefits:

*  Robust surge and enhanced ESD protection permits worry-free implementations in the world's most challenging environments.

*  Low dynamic resistance ensures fast acting, low clamping protection for  modern electronics, providing up to a 50% reduction in clamping voltage  over competing technologies.

*  Robust monolithic construction means they have no inherent wear-out  factor, so they can outlast the equipment they protect.

*  Designed to handle multiple ESD or surge transients without performance  degradation.

*  Industry standard SOD-323 package fits inside existing 0805 PCB footprints.

*  AEC-Q101 qualified for use in automotive electronics, ensuring maximum  reliability.

SD and SD-C Series TVS Diode Arrays are available in quantities of 3000 in tape and reel packaging.
