ESD protection diodes

Bidirectional symmetrical protection for CAN

Vishay Intertechnology has released bidirectional symmetrical ESD protection diodes in SOT-323 packages. They have a capacitance down to 10 pF for CAN protection in automotive applications.

MEASURING ONLY 2,3 mm by 2,1 mm with a low 0,95 mm profile, the semiconductors VLIN26A1-03G (single-line) and VCAN26A2-03G (dual-line) offer low capacitance and leakage current for the protection of automotive data lines against transient voltage signals.

For LIN 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 and Flexray applications. The AEC-Q101-qualified devices feature load capacitance of 10 pF typical and 15 pF maximum, maximum leakage current of < 0,05 µA, and a working voltage of ± 26,5 V. The protection diodes are lead (Pb)-free and RoHS-compliant.

Vishay Intertechnology is a manufacturer of discrete semiconductors (diodes, Mosfets, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in many types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
