VARISTOR (P/N v47za1) - New

The v47za1 is a metal-oxide varistor (MOV) designed to suppress transient voltage spikes in aircraft electrical systems. This 47V-class device clamps surge and lightning-induced transients across low-voltage DC bus nodes, protecting sensitive avionics and control circuits from overvoltage damage. Rated for 30 VAC / 38 VDC operation, it follows DO-160 Section 22 transient suppression practices.

Installation requires placement across specified circuit nodes with proper lead spacing per aircraft wiring diagrams to ensure effective clamping during fault conditions.

What is the VARISTOR (P/N v47za1)?

The v47za1 is a metal-oxide varistor (MOV) designed to suppress transient voltage spikes in aircraft electrical systems. This 47V-class device clamps surge and lightning-induced transients across low-voltage DC bus nodes, protecting sensitive avionics and control circuits from overvoltage damage.

Is the v47za1 compatible with my aircraft's avionics suite?

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

Does the v47za1 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 v47za1?

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.
