It offers good protection with a low clamping voltage, high trigger voltage, and minimal footprint, making it ideal for space-constrained automotive applications.
Vishay Intertechnology, Inc. has introduced a new automotive grade bidirectional singleline ESD protection diode, the VETH100A1DD1, housed in the compact DFN10062B package with wettable flanks. This device is specifically engineered for automotive Ethernet networks, adhering to the OPEN Alliance 100BaseT1 and 1000BaseT1 specifications. It offers protection for highspeed data lines against transient voltage signals while minimizing space usage.It has smaller footprint and lower profile compared to standard packages.
The key features involves:
- Very low clamping voltage of 31 V at 1 A, achieved through snapback technology.
- Trigger voltage exceeds 100 V, enhancing protection capabilities.
- Low dynamic resistance of 0.4 Ω improves ESD absorption capability.
- Superior protection due to enhanced ESD absorption.
- Low maximum capacitance of 2 pF ensures high signal integrity.
- Ideal for protecting sensitive data lines.
This protection diode is designed to provide transient protection for data lines in compliance with ISO 10605 and IEC 6100042 standards, offering ±15 kV contact discharge protection for up to 1000 pulses. For automotive applications, it is available in an AECQ101-qualified version, with a working voltage of ±24 V. Its versatile application range includes industrial automation systems, computers, consumer electronics, home appliances, fixed telecom infrastructure, and medical instrumentation.
It also features a moisture sensitivity level (MSL) of 1, in line with JSTD020 standards, and carries a UL 94 V0 flammability rating. The device is RoHS compliant, halogen-free, and adheres to the company’s Green standards. It supports automated optical inspection (AOI), ensuring reliability and performance in automotive systems.
