ESD protection diode for automotive ethernet networks

Vishay Intertechnology, Inc. has released a new automotive-grade bidirectional single-line ESD protection diode in the compact DFN1006-2B package with wettable flanks. Optimised for automotive Ethernet networks in compliance with OPEN Alliance 100Base-T1 and 1000Base-T1 specifications, the space-saving VETH100A1DD1 provides low clamping voltage, dynamic resistance, and capacitance for protecting high-speed data lines against transient voltage signals.

Providing a smaller footprint and lower profile than other standard packages, the device features a very low clamping voltage of 31V typical at 1A, a result of its snap-back technology with a trigger voltage >100V. Combined with a low dynamic resistance of 0.4W typical, the protection diode delivers improved ESD absorption performance and protection, while its low maximum capacitance of 2pF allows higher signal integrity.

The device provides transient protection for data lines as per ISO 10605 and IEC 61000 4 2 at ±15kV (contact discharge) for 1000 pulses. The protection diode is available in an AEC-Q101 version for automotive applications and offers a working voltage of ±24V. End products for the device include industrial automation systems, computers, consumer entertainment devices, home appliances, fixed telecom infrastructure, and medical instrumentation.

The protection diode provides a moisture sensitivity level (MSL) of 1 in accordance with J-STD-020 and a UL 94 V-0 flammability rating. RoHS-compliant, halogen-free, and Vishay Green, the device supports AOI for automotive systems.
