DIODE (P/N 42810-94710) - New Surplus

The 42810-94710 is a semiconductor diode for aircraft electrical systems that conducts current in one direction only, protecting circuits from reverse polarity damage and voltage transients. Commonly used across relay coils as a suppression device to dissipate flyback energy and safeguard avionics equipment. This component conforms to MIL-PRF-19500 aerospace performance specifications for reliability in flight-critical applications.

Installation must follow the aircraft wiring diagram and maintenance manual exactly, with proper orientation and verification that the diode matches the intended circuit requirements. Correct polarity is essential for effective transient suppression and circuit protection.
