Data supporting Orban, et al paper reporting the electrical transport properties of right-handed/left-handed and right-handed/right-handed devices fabricated from single crystals of the structurally chiral superconductor Mo3Al2C. Fraunhofer- like magnetic diffraction patterns confirm the presence of Josephson effect in all but one of the devices. A magnetic-field-induced superconducting diode effect is demonstrated in the right-handed/left-handed devices by a statistically significant difference in Ic+ and |Ic−|, with a maximum asymmetry of 5%. The intrinsic superconducting diode effect is not observed in the right-handed/right-handed devices.
