The Multiquip EE5739 is a genuine OEM Single Phase Flyback Bridge Diode 35A designed for MQ Power Fuel and DEF Tank units including the DEFTANK1, DEFTANK2, and DEFTANK302. As a direct OEM replacement, this diode is built to the same electrical specifications as the original component, ensuring correct current handling and circuit protection within your tank management system. Sourced directly through Multiquip's authorized parts network, the part is the right call when you need a verified replacement that matches the original part exactly.
Key Features
- 35A Rated Current Capacity — Engineered to handle the full 35-amp load demand of the single-phase flyback bridge circuit, maintaining electrical integrity under continuous operating conditions.
- Flyback Voltage Suppression — Designed to clamp inductive voltage spikes generated when switching loads are disconnected, protecting downstream electronics from damage.
- Direct OEM Replacement — Matches the original EE5739 specification for a drop-in installation with no re-wiring or circuit modification needed.
- Confirmed Fitment — Compatible with DEFTANK1, DEFTANK2, and DEFTANK302 MQ Power Fuel and DEF Tank systems.
- Electrical System Protection — A correctly functioning bridge diode prevents reverse-polarity current flow and suppresses transient spikes that can damage control boards and sensitive system components.
- Genuine OEM Part — Supplied by Multiquip, ensuring the component meets the original design specification for the DEF and fuel tank electrical system.
A flyback bridge diode serves as a critical protective component in the electrical circuit of fuel and DEF tank systems. It rectifies alternating current in single-phase applications and suppresses the high-voltage flyback spikes that occur when inductive loads — such as solenoids or pump motors — are switched off, preventing those spikes from damaging the control electronics. When this diode fails, the system may experience erratic electrical behavior, component damage, or complete circuit failure, making timely replacement essential to keeping the DEF and fuel delivery system operating correctly.
