Product Description
The 261-176 is a silicon diode for aircraft electrical systems, providing one-way current conduction for rectification and protection circuits. Installed across relay and contactor coils as a flyback diode, it suppresses inductive voltage spikes that occur during coil de-energization. Built to MIL-PRF-19500 quality standards for aerospace reliability.
Proper polarity installation is critical—observe markings and follow the aircraft maintenance manual for mounting location and orientation. Common in general aviation and commercial aircraft electrical architectures where transient protection prevents component damage.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
Frequently Asked Questions
What is the DIODE (P/N 261-176)?
The 261-176 is a silicon diode for aircraft electrical systems, providing one-way current conduction for rectification and protection circuits. Installed across relay and contactor coils as a flyback diode, it suppresses inductive voltage spikes that occur during coil de-energization.
Is the 261-176 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 261-176 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 261-176?
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.
