Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NRVB8H100MFST3G are determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 8 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 2 µA @ 100 V

Mechanical Parameters (Must Match):

• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: 8-PowerTDFN, 5 Leads
• Supplier Device Package: 5-DFN (5x6) (8-SOFL)
• Operating Temperature - Junction: -55°C ~ 175°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts maintain identical electrical, mechanical, and compliance specifications. Variations in packaging format (Tape & Reel, Cut Tape, Digi-Reel) and product status (Active vs. Obsolete) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: NRVB8H100MFSWFT3G

The NRVB8H100MFSWFT3G is the preferred substitute for the obsolete NRVB8H100MFST3G. This part maintains complete electrical and mechanical equivalence while offering Active product status, ensuring long-term availability and supply chain stability. The part carries AEC-Q101 automotive qualification and Automotive grade designation, providing enhanced reliability documentation. Inventory availability is substantial at 55,100 units. This part is suitable for both standard and automotive-grade applications.

Secondary Recommendation: NRVB8H100MFSWFT1G

The NRVB8H100MFSWFT1G provides an alternative with Active product status and AEC-Q101 qualification. This part is functionally equivalent and carries automotive-grade designation. Inventory availability is 1,153 units. Selection of this part is appropriate when automotive qualification is required and supply from the primary recommendation is constrained.

Tertiary Recommendation: MBR8H100MFST1G

The MBR8H100MFST1G is an Active product with complete electrical and mechanical equivalence. This part differs in base product number (MBR8H100 vs. NRVB8H100) but maintains identical performance specifications. Inventory availability is 2,043 units. This part is suitable for standard-grade applications where automotive qualification is not required.

Alternative: NRVB8H100MFST1G

The NRVB8H100MFST1G maintains complete equivalence but carries Obsolete product status. This part should be selected only when existing inventory is available and supply chain continuity is not a concern. Inventory availability is 2,053 units.

Frequently Asked Questions (FAQ)

Q: Can NRVB8H100MFSWFT3G be used as a direct replacement for NRVB8H100MFST3G?

A: Yes. The NRVB8H100MFSWFT3G is a direct functional equivalent. All electrical parameters (100 V reverse voltage, 8 A current rating, 900 mV forward voltage, fast recovery speed, and reverse leakage characteristics) are identical. The mechanical package (5-DFN, 5x6) and pin configuration are identical. The primary difference is packaging format (Tape & Reel vs. Tube) and product status (Active vs. Obsolete).

Q: What is the difference between the NRVB8H100MFSWFT3G and NRVB8H100MFSWFT1G?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability (55,100 units vs. 1,153 units). Both carry AEC-Q101 automotive qualification and Automotive grade designation. Selection between these parts should be based on supply availability and procurement lead time requirements.

Q: Why does MBR8H100MFST1G have a different base product number?

A: The MBR8H100MFST1G uses the MBR8H100 base product number instead of NRVB8H100. Despite this nomenclature difference, all electrical and mechanical specifications are identical. Both are onsemi Schottky rectifier diodes with the same performance characteristics and package configuration.

Q: Are the automotive-qualified parts (NRVB8H100MFSWFT3G and NRVB8H100MFSWFT1G) required for my application?

A: Automotive qualification (AEC-Q101) is required only if your application is automotive-grade or requires automotive-level reliability documentation. For standard industrial or consumer applications, non-automotive-qualified equivalents (MBR8H100MFST1G or NRVB8H100MFST1G) provide identical electrical and mechanical performance.

Q: Does packaging format (Tape & Reel vs. Cut Tape vs. Tube) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. All substitute parts deliver identical electrical performance regardless of packaging format. Selection should be based on manufacturing equipment compatibility and procurement requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 Compliant status and REACH Unaffected status, matching the compliance profile of the original NRVB8H100MFST3G.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.
