Vishay Semiconductors VBUS05B1-SD0 ESD protection diode

Vishay Intertechnology has released a bidirectional symmetrical (BiSy) single-line ESD protection diode for portable electronics in the ultracompact CLP0603 package. Measuring 0.6 x 0.3 x 0.27 mm, the Vishay Semiconductors VBUS05B1-SD0 is suitable for the protection of high-speed data lines and antennas against transient voltage signals.

The product’s chip-level package in the 0603 case size requires three times less board space than packages in the 1006 case size. Due to its short leads and small package size, the diode’s line inductance is very low, allowing fast transients such as an ESD strike to be clamped with minimal over- or undershoots.

With low load capacitance of 0.29 pF typical and 0.4 pF maximum, the diode can be used for the protection of high-speed data ports like HDMI, USB 3.0 and Thunderbolt in smartphones, digital cameras, MP3 players and portable gaming systems. The device features a low maximum leakage current of <0.1 μA at the working voltage of 5.5 V, a breakdown voltage of 8.8 V typical at 1 mA and a maximum clamping voltage of 18 V at 2.5 A.

The product provides transient protection for one data line as per IEC 61000 4 2 at ±16 kV (air and contact discharge). It offers a moisture sensitivity level of 1 in accordance to J-STD-020 and a UL 94 V-0 flammability rating. The unit also supports reflow soldering to +260°C for 10 s per JEDEC STD-020.
