TVS Diode Arrays Offer 60 Percent Lower Clamping Voltages than Alternative Technologies

Littelfuse, Inc. has introduced the SPHV (uni-directional) and SPHV-C (bi-directional) Series 200W Discrete TVS Diode Arrays (SPA® Diodes), that are designed to protect sensitive equipment from damage due to electrostatic discharge (ESD) and other overvoltage transients far better than earlier technologies. The SPHV and SPHV-C Series can safely absorb repetitive ESD strikes above the maximum level of the IEC61000-4-2 international standard without performance degradation and can safely dissipate up to 8A of induced surge current with very low clamping voltages. With their SOD882 packages, they are well suited for replacing 0402-sized multilayer varistors (MLVs) in applications such as automotive electronics, LED lighting modules, portable instrumentation, general purpose I/O, mobile and handheld devices, CAN and LIN busses, RS?232/RS?485, and other various low-speed I/Os. They are also excellent solutions for designers who need to "sprinkle" ESD and/or surge protection devices around their printed circuit boards.

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

  • ESD protection up to ±30kV (contact discharge) and surge protection up to 8A (tP=8/20µs), helping equipment manufacturers comply with and exceed industry standards, and extending equipment life and system uptime.
  • Low dynamic resistance provides up to 60 percent lower clamping voltages than alternative technologies, making them ideal for protecting modern electronics filled with small-geometry ICs.
  • Made with silicon diodes capable of handling multiple (>1000) ESD strikes or surge transients without performance degradation compared to previous technologies that have an inherent wear-out factor.
  • AEC-Q101 qualified products are ready for use in automotive electronics, ensuring maximum reliability.

The SPHV and SPHV-C Series TVS Diode Arrays is available in quantities of 10,000 in tape and reel packaging. Sample requests can be placed through authorized Littelfuse distributors worldwide.
