Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected based on strict equivalence or compatibility within the following key parameters: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) at relevant current, Reverse Recovery Time (trr), Reverse Leakage Current at Vr, mounting style, and package type. Only parts matching or exceeding the voltage and mechanical requirements, and within specified current and speed ranges, are included.

Parameter Comparison

Engineering Selection Recommendations

The MUR440GP-AP is designated as "Not For New Designs".
