A new bidirectional symmetrical (BiSy) single-line ESD protection diode comes in a compact 0.6mm x 0.3mm x 0.27mm CLP0603 package from Vishay Intertechnology. The VBUS05B1-SD0 offers low capacitance of 0.29pF and leakage current of

The VBUS05B1-SD0'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 a load capacitance range of 0.29pF to 0.4pF, the VBUS05B1-SD0 can be used for the protection of high-speed data ports like HDMI, USB 3.0 and Thunderbolt in smartphones, mobile phones, digital cameras, MP3 players and portable gaming systems. The device features a maximum leakage current of The VBUS05B1-SD0 provides transient protection for one data line as per IEC 61000 4 2 at 16kV (air and contact discharge). The device offers a moisture sensitivity level (MSL) of 1 in accordance to J-STD-020, a UL 94V-0 flammability rating, and supports reflow soldering to 260C for 10s per JEDEC STD-020. The protection diode is RoHS-compliant, halogen-free, and Vishay GREEN.

Samples and production quantities of the new VBUS05B1-SD0 are available now, with lead times of eight weeks for large orders.
