Key Parameters

Substitute Part Grouping Explanation

Substitution of the NRVTS1245EMFST1G is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io): 12 A
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 12 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 45 V

Mechanical & Compliance Parameters:

• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101
• Package / Case: 8-PowerTDFN, 5 Leads
• Supplier Device Package: 5-DFN (5x6) (8-SOFL)
• Operating Temperature - Junction: -55°C ~ 175°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The NRVTS1245EMFST1G and NRVTS1245EMFST3G are parametric equivalents with identical electrical and mechanical specifications. Both parts are manufactured by onsemi, carry AEC-Q101 automotive qualification, and comply with ROHS3 standards.

NRVTS1245EMFST1G is designated Last Time Buy with 4550 units in stock. This status indicates the manufacturer has announced end-of-life production, with current inventory representing the final available supply.

NRVTS1245EMFST3G is designated Obsolete with 1005 units in stock. This status indicates the part is no longer manufactured and available inventory is limited.

For new designs or long-term production requirements, evaluation of alternative Schottky rectifier diodes with equivalent 45V/12A ratings and 5-DFN packaging from onsemi or other qualified manufacturers is recommended to ensure sustained component availability beyond current inventory levels.

Frequently Asked Questions (FAQ)

Q: Are NRVTS1245EMFST1G and NRVTS1245EMFST3G direct substitutes?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (45V, 12A, 600mV forward voltage), identical Schottky technology, identical AEC-Q101 automotive qualification, and identical 5-DFN (5x6) package configuration. They are electrically and mechanically interchangeable.

Q: What is the difference between Last Time Buy and Obsolete status?

A: Last Time Buy indicates the manufacturer has announced end-of-life production with current inventory representing the final available supply. Obsolete indicates the part is no longer manufactured. Both statuses indicate limited availability.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. Both parts carry AEC-Q101 automotive qualification and are rated for operating junction temperatures from -55°C to 175°C, meeting automotive environmental and reliability requirements.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 8-PowerTDFN, 5-lead package with 5-DFN (5x6) (8-SOFL) supplier device package designation. No PCB layout modifications are required for substitution.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require moisture-controlled storage or baking procedures prior to assembly, simplifying inventory management and reducing handling requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both NRVTS1245EMFST1G and NRVTS1245EMFST3G are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for EU and global markets.
