Substitute Part Grouping Explanation

Substitution for the FR6AR02 diode is determined strictly on matching electrical and mechanical parameters. Key criteria are: voltage - DC reverse (Vr) (Max), average rectified current (Io), voltage - forward (Vf) (Max) @ If, reverse recovery time (trr), speed, current - reverse leakage @ Vr, mounting type, package/case, operating temperature range, and RoHS status. Substitute parts must meet or exceed these requirements as defined in the provided data.
