Engineering Selection Recommendations

The MBR30H100MFST1G is classified as obsolete. Three active substitute parts are available: MBR30H100MFST3G, NRVB30H100MFST1G, and NRVB30H100MFST3G. All substitute parts maintain identical electrical specifications and physical packaging, ensuring direct functional compatibility.

MBR30H100MFST3G is the primary MBR series alternative, available in Tape & Reel packaging with 5989 units in stock. This part carries active product status and full ROHS3 compliance.

NRVB30H100MFST1G and NRVB30H100MFST3G represent the NRVB series alternatives, both with active product status. NRVB30H100MFST1G is available in 1335 units, while NRVB30H100MFST3G is available in 1400 units, both in Tape & Reel packaging.

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting the same regulatory and environmental requirements as the original part.

Frequently Asked Questions (FAQ)

Q: Can MBR30H100MFST3G directly replace MBR30H100MFST1G?

A: Yes. MBR30H100MFST3G is a direct functional equivalent. Both parts share identical electrical ratings (100 V, 30 A, 900 mV forward voltage), recovery speed characteristics, and physical packaging (5-DFN 5x6). The primary difference is packaging format: MBR30H100MFST1G uses standard packaging while MBR30H100MFST3G is supplied in Tape & Reel format.

Q: What is the difference between MBR and NRVB series diodes?

A: Both MBR and NRVB series are onsemi Schottky rectifier diodes with identical electrical and mechanical specifications for this voltage and current rating. The series designation reflects different product lines within onsemi's portfolio. All listed parts maintain the same 100 V reverse voltage, 30 A current rating, and 5-DFN package.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MBR30H100MFST1G, MBR30H100MFST3G, NRVB30H100MFST1G, and NRVB30H100MFST3G are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What does the "3G" suffix indicate in part numbers?

A: The "3G" suffix indicates Tape & Reel packaging format. The "1G" suffix indicates standard packaging. Both formats contain identical diode components with the same electrical performance and physical dimensions.

Q: Can I use NRVB30H100MFST1G or NRVB30H100MFST3G as substitutes?

A: Yes. NRVB30H100MFST1G and NRVB30H100MFST3G are direct functional equivalents to MBR30H100MFST1G. All electrical parameters, package dimensions, and operating temperature ranges are identical. Both NRVB parts carry active product status.

Q: What is the operating temperature range for all substitute parts?

A: All parts, including the original MBR30H100MFST1G and all substitutes, operate across a junction temperature range of -55°C to 150°C.

Q: Are there any differences in reverse leakage current between substitute parts?

A: No. All parts maintain identical reverse leakage current of 100 µA at 100 V reverse voltage.
