Vishay Intertechnology, Inc. has released a 4-line ESD protection array for portable electronics in the ultra-compact chip-level CLP1007-5L package. Offering an extreme size reduction over previous generation components without sacrificing performance, the Vishay Semiconductors VBUS54FD-SD1 offers low capacitance and leakage current for the protection of high-speed data lines against transient voltage signals.

Measuring only 1.0 mm by 0.7 mm with a low height of 0.27 mm, the protection array released today utilizes 70% less board space than previous-generation devices and provides a seven-fold reduction in volume. Offering a low load capacitance of 0.9 pF typical and a “flow through” design, the VBUS54FD-SD1 is optimized to protect high-speed data lines including HDMI, DisplayPort, eSATA, USB 3.0, 1394 / FireWire, and Thunderbolt in mobiles phones, digital cameras, MP3 players and portable gaming systems. The space-saving device also makes it possible to provide USB 3.0 interface protection in smartphones for the first time.

The protection array features a low maximum leakage current of < 0.1 µA at the working voltage of 5.5 V, a breakdown voltage of 7.5 V typical at 1 mA, and a maximum clamping voltage of 15 V at 3 A. The VBUS54FD-SD1 provides transient protection for data lines as per IEC 61000-4-2 at ± 15 kV (air and contact discharge). The device offers a moisture sensitivity level (MSL) of 1 in accordance to J-STD-020, supports reflow soldering to +260 °C for 10 s.

Samples and production quantities of the new VBUS54FD-SD1 are available now, with lead times of eight weeks for large orders.
