Product Description

Part 20-3940-e002201 is a diode for aircraft DC electrical systems, providing rectification and transient suppression in starter circuits. Installed across starter contactor coils as a flyback path, it protects switches and avionics from inductive voltage spikes generated during coil de-energization. The diode must be installed with correct polarity per the aircraft wiring diagram and maintenance manual.

Aerospace-grade construction meets MIL-PRF-19500 screening standards for reliability in harsh flight environments.
