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

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

The VETH100A1DD1 provides transient protection for data lines as per ISO 10605 and IEC 61000-4-2 at ± 15 kV (contact discharge) for 1000 pulses. For automotive applications, the protection diode is available in an AEC-Q101 version and offers a working voltage of ±24 V. End products for the device include industrial automation systems, computers, consumer entertainment devices, home appliances, fixed telecom infrastructure, and medical instrumentation.

The protection diode offers a moisture sensitivity level (MSL) of 1 by J-STD-020 and a UL 94 V-0 flammability rating. Being RoHS-compliant, halogen-free, and Vishay Green, the device supports automated optical inspection (AOI) for automotive systems.
