• Provides onboard surge protection capabilities for sensitive electronic circuits
• Supports high-voltage operation up to 140 VDC for robust system resilience
• Engineered for high efficiency in switching surge stopper applications

Applications

• Automotive systems requiring transient voltage suppression
• Avionics equipment needing reliable power line protection
• Industrial control units exposed to electrical noise

Procurement Notes

Availability for the LTC7862IUFD#PBF is currently restricted. Mouser reports that this specific part number is not supplied in your region, indicating potential limited sales or factory special order status. Verify supply chain constraints before design finalization. Contact the manufacturer or authorized distributors directly to confirm current production status and lead times, as standard inventory may not be accessible through typical retail channels.

Selection Notes

Select this component when designing systems requiring integrated surge protection for input voltages between 4 VDC and 140 VDC. Ensure the application environment falls within the specified -40°C to +125°C operating temperature range. The QFN-20 package requires compatible PCB footprint design. Consider the 1.2 mA current rating to verify compatibility with downstream circuit requirements. Validate suitability for automotive, avionics, or industrial standards prior to implementation.

Part Context

This part belongs to the LTC7862 series of surge suppressors produced by Analog Devices Inc. It serves as a specialized solution for protecting board-mounted electronics against voltage spikes. The component integrates surge stopping functionality into a compact surface-mount form factor, distinguishing it from discrete protection devices. Its classification under Board Mount Surge Protectors highlights its role in enhancing system reliability against transient events.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative surge protectors based on matching voltage ratings (4-140 VDC), package compatibility (QFN-20), and thermal specifications. Consult Analog Devices technical support for direct cross-reference recommendations if this specific part number becomes unavailable.
