The search for a material combination providing the best performances for the required application is continuously ongoing. Here, we present a superconducting spintronic tunnel diode based on the strong spin filtering and splitting generated by an EuS thin film between a superconducting Al and a normal metal Cu layer. The Cu/EuS/Al tunnel junction achieves a large rectification (up to $\\sim40$\\%) already for a small voltage bias ($\\sim 200$ $\\mu$V) thanks to the small energy scale of the system: the Al superconducting gap.
