TSPB15U100S S2G Equivalent & Substitute Parts

Part Overview

The TSPB15U100S S2G is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 15 A average rectified current. This component is designed for surface mount applications in the TO-277 / 3-PowerDFN package configuration (SMPC4.0 supplier package). The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part number becomes unavailable, discontinued, or when alternative packaging configurations are required while maintaining identical electrical performance and thermal characteristics.

Substitute Part Grouping Explanation

Substitution of the TSPB15U100S S2G is determined by strict equivalence across the following electrical and mechanical parameters:

Mandatory Equivalence Criteria:

• Voltage - DC Reverse (Vr) Maximum: 100 V
• Current - Average Rectified (Io): 15 A
• Voltage - Forward (Vf) Maximum @ If: 700 mV @ 15 A
• Speed - Fast Recovery: ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 250 µA @ 100 V
• Operating Temperature - Junction: −55°C to +150°C
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-277, 3-PowerDFN

Packaging Variants: Substitute parts may differ in supplier device package designation (SMPC4.0 versus TO-277A (SMPC)) while maintaining identical electrical performance and physical compatibility. Both packaging variants represent the same TO-277 / 3-PowerDFN case outline.

Engineering Selection Recommendations

TSPB15U100S S2G (Primary Part): This part is the recommended selection for new designs. It maintains active product status with full manufacturing support and carries ROHS3 compliance certification. The part is currently in stock with 1,094 units available.

TSP15U100S (Parametric Equivalent): This part provides complete electrical and thermal equivalence to the primary part. However, it carries a "Not For New Designs" product status designation. Selection of this part is appropriate only when existing inventory must be utilized or when design revisions are not feasible. The part is available in higher quantity (57,594 units).

TSPB15U100S (Parametric Equivalent): This part is electrically and mechanically identical to the primary part but carries a "Discontinued at DiGi Electronics" product status. It remains available through inventory channels (21,628 units) and is suitable for replacement applications where supply chain continuity is required. ROHS3 compliance and REACH unaffected status are maintained.

All three parts satisfy identical electrical performance requirements, thermal operating ranges, and regulatory compliance standards. Selection between these parts should be based on product status alignment with design phase requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can TSP15U100S be used as a direct replacement for TSPB15U100S S2G?

A: Yes. TSP15U100S provides complete parametric equivalence across all electrical specifications, thermal characteristics, and regulatory compliance certifications. The parts differ only in product status designation and supplier package nomenclature (TO-277A (SMPC) versus SMPC4.0), both representing the same TO-277 / 3-PowerDFN physical package.

Q: What is the difference between SMPC4.0 and TO-277A (SMPC) packaging?

A: Both designations refer to the same physical package outline (TO-277 / 3-PowerDFN). SMPC4.0 and TO-277A (SMPC) are alternative supplier nomenclature systems for identical package geometry and pin configuration. No physical or electrical differences exist between parts using these different package designations.

Q: Why is TSP15U100S marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While the part remains electrically and mechanically equivalent, it is not recommended for new product development. Existing inventory may be used for legacy system support or replacement applications.

Q: Why is TSPB15U100S marked "Discontinued at DiGi Electronics"?

A: This designation indicates the part has been removed from a specific distributor's active catalog. The part may remain available through alternative supply channels and inventory sources. Availability should be verified through current supplier networks before design commitment.

Q: Are all three parts RoHS3 compliant?

A: Yes. TSPB15U100S S2G, TSP15U100S, and TSPB15U100S all carry ROHS3 Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts share identical TO-277 / 3-PowerDFN package geometry and pin configuration, enabling direct substitution on existing printed circuit board layouts without design modification.
