Multiquip LBD555 Diode IN5402 3 Amp 200V

The Multiquip LBD555 Diode IN5402 3 Amp 200V is a genuine OEM electrical component designed for the Super-Silent Generator series, including the DCA70SSIU4F. Sourced directly from Multiquip, this diode is built to the exact electrical specifications required for correct generator operation — 3-amp current capacity and 200-volt reverse voltage rating. Genuine OEM designation means this part matches the component installed at the factory, ensuring no guesswork on electrical compatibility.

Key Features

• Correct Electrical Specification: — Rated at 3 amps and 200 volts reverse voltage, matching the precise electrical tolerances required in Super-Silent Generator charging and rectification circuits.
• Genuine OEM Component: — Supplied by Multiquip as a genuine OEM part, confirming this is the same diode used in original production builds — not an approximated substitute.
• Direct Drop-In Replacement: — Designed to install in the same position and circuit location as the original, with no lead modification or circuit adaptation needed.
• Confirmed Fitment for DCA Super-Silent Series: — Verified for the DCA70SSIU4F and the broader Super-Silent Generator family, so you can order with confidence against your machine's model code.
• Protects Generator Output Integrity: — A correctly functioning rectifier diode ensures clean, stable DC output from the alternator. A failed diode can cause voltage irregularities, battery charging failure, or complete loss of DC control power.
• Electrical Safety Assurance: — Using a diode rated to the correct voltage and current specification prevents overheating and insulation breakdown in the rectifier circuit — a genuine concern when substituting unrated components in generator electrical systems.

A rectifier diode like the LBD555 IN5402 is a one-way electrical valve within the generator's charging and control circuit. It converts alternating current from the alternator into the direct current needed to charge the battery and power control electronics, while blocking reverse current flow that could damage sensitive components. When a diode fails — either by shorting or opening — the generator may lose battery charging capability, display erratic electrical behavior, or fail to start due to loss of DC control voltage.
