TVS Diode Array Combines Low Dynamic Resistance with ESD Capability

Littelfuse Inc. has introduced the miniature four-channel bidirectional SP1015 Series TVS diode array, designed to protect data lines that may experience electrostatic discharge (ESD). These diodes can safely absorb repetitive ESD strikes (±20kV contact, ±30kV air) above the maximum level specified in the IEC61000-4-2 international standard without performance degradation. Their bidirectional configuration provides symmetrical ESD protection for data lines when AC signals are present.

By providing a low clamping voltage and 0.65W of dynamic resistance, the SP1015 Series is designed to protect the small-geometry integrated circuits used in modern electronic devices. It provides four lines of ESD protection in a low-profile flip chip package, making it suitable for applications where conserving board space is critical, including micro-SIM interfaces, touchscreen controller lines, and general purpose I/Os on smartphones, wearable devices, tablets, and eReaders.

SP1015 Series TVS Diode Arrays offer these key benefits:

  • Four lines of ESD protection in a 0.93 x 0.53 mm footprint
  • Configured for close placement to a micro-SIM (µSIM) socket
  • ESD protection beyond the maximum rating in the IEC61000-4-2 standard
  • Low dynamic resistance (0.65W) and low clamping voltage
  • Bidirectional configurations
  • 5V standoff voltage

The SP1015 Series is available in tape & reel form in quantities of 5,000.
