Feature Summary

• Dual serial configuration with integrated PN junction guard ring for stress protection
• Extremely fast switching speed with low turn-on voltage
• Molding compound meets UL 94 V-0 flammability rating
• Moisture Sensitivity Level (MSL) 1

Applications

• Ultra high-speed switching circuits
• Voltage clamping applications
• Reverse polarity protection
• Line termination

Procurement Notes

Verify the specific ordering code against official Vishay documentation to ensure correct packaging options. Confirm that the component meets required environmental standards such as RoHS compliance. Check for AEC-Q101 qualification if automotive grade reliability is necessary, as this may require a distinct part number suffix. Validate thermal resistance parameters against the intended PCB footprint design.

Selection Notes

Select this component when a compact dual-diode solution with low capacitance is required. The SOT-23 package provides space efficiency for dense layouts. Ensure the application operates within the specified 30 V reverse voltage limit. Consider the 5 ns reverse recovery time for high-frequency signal processing or rectification tasks where minimal switching loss is critical.
