Vishay Intertechnology has introduced a BiSy (bi-directional symmetrical) single-line ESD protection diode in the LLP1006 package. The compact VBUS05L1-DD1-G-08 provides a low capacitance of 0.3pF for the protection of antennas, USB 3.0, and HDMI ports from transient voltage signals in portable electronics.
Featuring a compact 0.6×1.0mm footprint with a low package height of less than 0.4mm, the device minimises the board space required for active ESD protection in applications such as portable gaming systems, digital cameras, MP3 players and mobile phones.
At the working voltage of 5.5V, the device offers a high isolation to ground characterised by a low leakage current of less than 0.1µA. Any transient voltage signal exceeding the reverse breakthrough voltage of 8.4V at 1mA will be "clamped" or "short" to ground. The device features a maximum clamping voltage of 14 at 1A.
Due to its short leads and small package size, the device's line inductance is low, allowing fast transients such as an ESD strike to be clamped with minimal over or undershoots. The device provides transient protection for one data line as per IEC 61000 4 2 at ± 9kV (air and contact discharge). The device is lead (Pb)-free and complies with RoHS 2002/95/EC and WEEE 2002/96/EC.
