OEX Alternator Diode Positive Denso/Hitachi Style RFX3053

OEX Alternator Diode Positive Denso/Hitachi Style RFX3053

If you’re after a reliable alternator diode to keep your system in top shape, look no further than the OEX Alternator Diode Positive. This diode is designed specifically for Denso and Hitachi-style alternators, ensuring smooth and efficient current flow. It’s built to protect your alternator’s internal electronics from voltage spikes, keeping your alternator running reliably without any hiccups. Whether you’re on the job site or off on a weekend adventure, this OEX diode ensures your alternator operates efficiently and without drama.

The OEX Alternator Diode features high thermal durability thanks to its silicon semiconductor and metal heat-sinking base. It’s designed to handle high temperatures in your engine bay, ensuring long-lasting reliability even under the harshest conditions. This positive diode allows current to flow in one direction—from the stator to the battery—preventing reverse current flow and helping protect the alternator’s charging system. With this OEX diode, you won’t have to worry about damage caused by reverse voltage or system failure.

Whether you're working in demanding environments or cruising around New Zealand’s rugged terrain, the OEX Alternator Diode Positive ensures your system stays reliable. It’s designed for high-current alternators (up to 50-100 amps) and is perfect for keeping your alternator in optimal condition. No more surprises—just smooth, efficient performance that’s built to last.
