DIODE (P/N in4005) - New Surplus

The 1N4005 is a silicon rectifier diode that controls current flow in one direction within aircraft electrical circuits. It suppresses voltage spikes generated by relay and contactor coils during switching, protecting sensitive avionics and control systems from transient damage. Install with the cathode band facing the coil positive terminal per wiring diagrams and FAA AC 43.13-1B guidance.

This JEDEC-standard component is essential for reliable DC circuit protection in general aviation electrical systems.

What is the DIODE (P/N in4005)?

The 1N4005 is a silicon rectifier diode that controls current flow in one direction within aircraft electrical circuits. It suppresses voltage spikes generated by relay and contactor coils during switching, protecting sensitive avionics and control systems from transient damage.

Is the in4005 compatible with my aircraft's avionics suite?

Avionics compatibility depends on your aircraft model and existing installation. The DIODE is available in: New Surplus. We recommend checking your aircraft's wiring diagrams and STC documentation, or contact our avionics team for compatibility assistance.

Does the in4005 come with an 8130-3 airworthiness tag?

Availability of an FAA 8130-3 tag depends on the part condition. Overhauled and repaired units typically include 8130-3 documentation. As-removed units may include a removal tag with trace history. Contact us for specific documentation on the condition you need.

Do you offer bench testing for the in4005?

We can arrange bench testing through our network of FAA-certified repair stations. Call (904) 998-9101 for testing availability and turnaround times, or submit an RFQ with your specific requirements.
