Automotive-grade diodes with peak pulse energy as much as 540 W and ±30 kV ESD immunity promise sturdy safety for autos, industrial programs, telecom, and shopper electronics.
Vishay Intertechnology, Inc. has launched two new Automotive Grade ESD safety diode collection — the single-line VGSOTxx and two-line VGSOTxxC — designed for demanding high-current purposes. Provided within the compact SOT-23 bundle, the gadgets ship peak pulse energy rankings as much as 540 W and present rankings as much as 44 A at an 8/20 µs pulse, outperforming Vishay’s earlier GSOTxx household.
Engineered with decrease thermal resistance, the brand new diodes improve warmth dissipation, enabling extra sturdy system designs for harsh environments. Goal purposes span throughout automotive electronics and controls, gasoline cells, sensible vitality programs, industrial automation, motor drives, energy instruments, telecom infrastructure, shopper home equipment, and even navy digital warfare programs.
The important thing options are:
- Two-line unidirectional ESD safety diode (frequent anode, can be utilized bidirectional)
- Single-line unidirectional ESD safety diode
- ESD immunity per IEC 61000-4-2, ISO 10605: ±30 kV contact, ±30 kV air discharge
The VGSOTxx and VGSOTxxC collection could be deployed as unidirectional ESD safety gadgets, whereas the twin, common-anode configuration of the VGSOTxxC collection additionally permits for bidirectional use. For purposes requiring larger energy dealing with, their dual-diode construction helps parallel operation, successfully doubling surge functionality, line capacitance, and reverse leakage present.
Compliant with IEC 61000-4-2 and ISO 10605 requirements, the brand new gadgets present ESD immunity of ±30 kV for each air and phone discharge, whereas additionally assembly the AEC-Q101 human physique mannequin class H3B (>8 kV). They’re totally RoHS-compliant, halogen-free, Vishay Inexperienced, and certified to Vishay’s Automotive Grade requirements, making certain long-term reliability and high quality.
Designed as direct drop-in replacements, the diodes simplify upgrades from Vishay’s earlier GSOT collection and competing SOT gadgets, providing prospects a straightforward path to increased energy and present efficiency with out redesign. Samples and manufacturing portions are already accessible, with customary lead occasions of 12 weeks.
