Key Parameters

Substitute Part Grouping Explanation

The listed substitute only includes components that match the following key parameters: product category (Diodes, Rectifiers), Schottky technology, maximum DC reverse voltage (150 V), average rectified current (3A), mounting type (Surface Mount), and identical mechanical package (TO-277, 3-PowerDFN or TO-277A). Voltage Forward (Vf) at rated current, speed class, and moisture sensitivity are also matched. These criteria ensure that the substitute part provides electrical and mechanical compatibility for applications originally designed for TSP3H150S.

Parameter Comparison

Engineering Selection Recommendations

The TSP3H150S is discontinued at Digi-Key, which makes alternatives necessary for ongoing designs and production. The substitute RB058RSM15STL1 is designated as active and supports the same product category, technology, and electrical parameters, as well as package and compliance requirements such as Moisture Sensitivity Level (MSL 1), ECCN, and RoHS/REACH status.
