MB8S Equivalent Parts

Cross Reference & Replacements

  2. MB8S Equivalent

When the MB8S is out of stock or unavailable, several equivalent bridge rectifier parts can serve as drop-in replacements. The key parameters to match are: VRRM ≥ 800 V, IF(AV) ≥ 0.5 A, SOIC-4 or TO-269AA package.

MB8S Cross Reference Parts

  • DB107S – 1000 V 1 A SOIC-4, higher voltage and current rating

  • GBJ0802 – 800 V 2 A, larger current but compatible footprint variants available

  • ABS10 – 800 V 1 A surface mount bridge rectifier

  • MB8S (Diotec) – Identical part from Diotec Semiconductor, TO-269AA/MiniDIL

  • MB8S (Yangjie) – Yangzhou Yangjie Electronic version, SOIC-4

  • MB8S (HY Electronic) – HY Electronic Corp version, glass passivated

Notes on Substitution

All MB8S equivalents must be verified against the application circuit requirements. When substituting with a higher-rated part such as the DB107S (1000 V, 1 A), the electrical performance will be equal or better, but verify the PCB footprint dimensions match exactly before substitution.

The onsemi MB8S (formerly ON Semiconductor) and the Fairchild MB8S are considered identical parts and fully interchangeable.
