A series of TVS Diode Arrays (SPA Diodes) has been introduced by Littelfuse. These have been designed to protect each I/O pin of electronic equipment subject to destructive electrostatic discharges (ESD) or Electrical Fast Transients (EFT). The new SP1064 Series TVS Diode Arrays are Zener diodes fabricated using a proprietary silicon avalanche technology. These robust diodes can safely absorb repetitive ESD strikes above the maximum level specified in IEC 61000-4-2 international standard without performance degradation.
Their low loading capacitance (typically 8.5pF per I/O) also makes them useful for protecting high speed signal pins.
Typical applications for the SP1064 series include protection for backlighting and edge lighting solutions for Ultra High Definition TVs, LCD/PDP/TVs, desktops/laptops and point of sale displays.
“SP1064 Series TVS Diodes offer circuit designers the ability to economically protect strings of up to 15 high brightness LEDS (HBLEDs) against ESD and EFT,” said Tim Micun, Global Product Manager, TVS Diode Arrays (SPA Diodes), Littelfuse. “That ensures a lower overall protection budget while still providing a high level of protection.”
SP1064 Series TVS Diodes offer these key benefits:
