Substitute Part Grouping Explanation

Suitable substitutes for the SS1150HE3-LTP are identified by strictly matching critical parameters: Schottky technology, maximum reverse voltage of 150 V, average rectified current of 1A, maximum forward voltage of 900 mV @ 1A, fast recovery speed, surface mount DO-214AC (SMA) package, and operational temperature range. RoHS and REACH compliance, as well as automotive qualification (e.g., AEC-Q101), are also considered in grouping. Only parts matching these explicit criteria are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SS1150HE3-LTP and SS1150-LTP are both active and have ROHS3 compliance and REACH unaffected status. Both are rated for unlimited moisture sensitivity level and share the same manufacturer and core specifications. Selection between these parts can be based on product status and compliance documentation as provided.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when substituting the SS1150HE3-LTP Schottky diode?
A1: The substitution requires matching the following parameters: technology (Schottky), maximum reverse voltage (150 V), average rectified current (1A), maximum forward voltage (900 mV @ 1A), speed, mounting type, package (DO-214AC, SMA), and operational temperature range. Compliance certifications (RoHS, REACH) and automotive qualification are also included when specified.

Q2: Can I use a part with a higher reverse leakage current or capacitance?
A2: Only substitute with a part if the parameters provided—particularly reverse leakage current and capacitance—meet the required limits for the specific design purpose as per provided values. Only values listed above are to be considered.

Q3: Are package and mounting type critical for substitution?
A3: Yes. The substitute part must have the same mounting type (surface mount) and identical package (DO-214AC, SMA) as the SS1150HE3-LTP to ensure direct compatibility.

Q4: Is automotive qualification a requirement for substitution?
A4: Automotive qualification (e.g., AEC-Q101) is considered a key parameter when explicitly listed. Only substitute with parts that match the specified qualification status.

Q5: Does product status affect selection?
A5: Both the SS1150HE3-LTP and SS1150-LTP are listed as active. Product status should be checked to ensure continued availability for production and maintenance requirements.
