The Bomag 434022739 Diode is a genuine OEM electrical component designed for Bomag BF-series pavers, including the BF 222 C, BF 223 C, BF 600 P-E, BF 600 C-E, BF 691 C, and BF 691 C-HSE, among others across the BF 600 and BF 691 paver families. Sourced directly from Bomag, this diode matches the original specification for correct polarity protection and current regulation within the machine's electrical system. It installs directly in place of the factory component, ensuring no guesswork on compatibility across the covered BF-series paver lineup.
Key Features
- Genuine OEM Electrical Accuracy — manufactured to Bomag's exact forward-voltage and current-rating specification, ensuring the diode performs identically to the original component it replaces
- Correct Polarity and Circuit Protection — this diode allows current to flow in only the intended direction, protecting sensitive downstream electrical components from reverse-current damage
- Direct Drop-In Replacement — matched to the original mounting configuration and terminal arrangement for a straightforward swap on covered BF-series pavers
- Broad BF-Series Paver Coverage — fits Bomag pavers including the BF 222 C, BF 223 C, BF 223 C HFE, BF 600 P-E, BF 600 C-E, BF 600 P HSE, BF 691 C, BF 691 C-HSE, BF 691 P-HSE, and additional BF 600 and BF 691 variants
- Electrical System Integrity — a failed diode can cause erratic charging behavior, control system faults, or component damage; replacing with the correct part number 434022739 restores proper circuit function immediately
- Verified Fitment Confidence — using a genuine Bomag part ensures the diode's electrical characteristics align with the paver's designed operating parameters, reducing the risk of repeat failures
A diode is a one-way electrical valve — it allows current to pass in a single direction while blocking flow in reverse. In Bomag pavers, diodes are used to protect circuits, regulate charging paths, and prevent back-feeding between electrical subsystems. When a diode fails, it can either short the circuit (allowing current to flow in both directions) or open completely (blocking all current), both of which can cause control malfunctions, sensor faults, or damage to other electrical components. Replacing a faulty diode promptly with the correct OEM part restores proper electrical flow and protects the broader system.
