Low-capacitance ESD protection diodes save automotive board space

Latest from Vishay is a new bi-directional symmetrical (BiSy) ESD protection diodes in the compact SOT-323 package. Measuring only 2.3mm x 2.1mm with a low 0.95mm profile, the space-saving single-line VLIN26A1-03G and dual-line VCAN26A2-03G offer low capacitance and leakage current for the protection of automotive data lines against transient voltage signals. For LIN bus applications, the VLIN26A1-03G provides transient protection for one data line as per IEC 61000 4 2 at ± 30 kV (air and contact discharge), while the VCAN26A2-03G protects two lines for CAN-Bus and FLEX-Bus applications. The AEC-Q101-qualified devices feature low load capacitance of 10pF typical and 15pF maximum, low maximum leakage current of < 0.05µA, and a working voltage of ± 26.5 V. The protection diodes are lead (Pb)-free and RoHS-compliant. Samples and production quantities are available now, says the company.
