SB 8.24.11
yo ’sav asmin maha-kalpe
tanayah sa vivasvatah
sraddhadeva iti khyato
manutve harinarpitah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this [the present] millennium King Satyavrata later became the son of Vivasvan, the king of the sun planet, and was known as Sraddhadeva. By the mercy of the Supreme Personality of Godhead, he was given the post of Manu.
