Bidirectional symmetrical (BiSy) ESD protection diodes in the compact SOT-323 package have been introduced by Vishay Intertechnology. Measuring only 2.3x2.1mm with a low 0.95mm profile, the space-saving Vishay Semiconductors 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 ±30kV (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 less than 0.05μA, and a working voltage of ±26.5V. The protection diodes are lead (Pb)-free and RoHS-compliant.
Samples and production quantities of the new VLIN26A1-03G and VCAN26A2-03G are available now, with lead times of eight weeks for large orders.
