New ESD protection diodes designed for high current rating applications

Vishay Intertechnology, Inc. has introduced two new series of automotive grade 3.3V to 36V ESD protection diodes in the SOT-23 package. Providing low thermal resistance, the single-line VGSOTxx and two-line VGSOTxxC series ensure more efficient heat dissipation than the previous generation GSOTxx/xxC devices, permitting for a more robust design that allows higher peak pulse power ratings up to 540W and current ratings up to 44A at an 8/20µs pulse.

With their high power and current capabilities, the Vishay Semiconductors devices are excellent for a wide range of applications. They will be employed in automotive electronics and controls, fuel cells, and smart systems; energy monitoring and metering systems; industrial automation systems, motor drives, and power tools; computers and computer peripherals; consumer appliances and entertainment and healthcare devices; fixed and mobile telecom infrastructure; medical instrumentation; and military electronic warfare systems.

The series can be utilised as unidirectional ESD protection devices. With their dual, common anode configuration, VGSOTxxC series components can also serve as bidirectional devices. If higher power is required, their dual diodes can be used in parallel to double their surge power ratings, line capacitance, and reverse leakage current.

RoHS-compliant, halogen-free, and Vishay Green, the VGSOTxx and VGSOTxxC series provide ESD immunity in accordance with IEC 61000-4-2 and ISO 10605 (±30kV air and contact discharge), as well as the AEC-Q101 human body model: class H3B (>8kV).

The devices provide direct drop-in replacements for Vishay's previous-generation GSOT diodes and competing SOT series devices and are available in AEC-Q101 qualified versions. These new products also fulfil the Vishay Automotive Grade needs to ensure continuous excellent quality at the highest level.

Samples and production quantities of the new ESD protection diodes are available now.
