Key Parameters

Substitute Part Grouping Explanation

Substitution of the RFN1VWM2STR is determined by strict equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage must equal 200 V
• Current Rating: Average rectified current must equal 1 A
• Forward Voltage Drop: Maximum forward voltage must equal 930 mV @ 1 A
• Recovery Characteristics: Reverse recovery time must equal 25 ns with fast recovery classification
• Reverse Leakage: Maximum reverse leakage current must equal 1 µA @ 200 V
• Package Compatibility: Surface mount configuration with 2-SMD, Flat Lead package and PMDE supplier device package
• Thermal Rating: Junction temperature rating must equal 175°C
• Compliance: RoHS3 compliance and MSL 1 rating required

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

Parameter Comparison

Engineering Selection Recommendations

Both the RFN1VWM2STR and RFN1VWM2STFTR are Active products manufactured by Rohm Semiconductor with identical electrical and mechanical specifications. Both components carry ROHS3 compliance certification and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. Selection between these parts may be based on packaging format (Tape & Reel designation) and current inventory availability. The RFN1VWM2STFTR currently maintains higher inventory levels at 2468 pieces compared to 1607 pieces for the RFN1VWM2STR, which may influence procurement decisions for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can RFN1VWM2STFTR be used as a direct replacement for RFN1VWM2STR?

A: Yes. Both parts are parametric equivalents with identical voltage ratings (200 V), current ratings (1 A), forward voltage characteristics (930 mV @ 1 A), reverse recovery time (25 ns), and reverse leakage specifications (1 µA @ 200 V). Package configuration, mounting type, and thermal ratings are identical.

Q: Are there differences in packaging between these substitute parts?

A: Both parts are supplied in Tape & Reel (TR) format with 2-SMD, Flat Lead package configuration and PMDE supplier device package designation. No packaging differences exist between the two parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RFN1VWM2STR and RFN1VWM2STFTR are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What is the difference between RFN1VWM2STR and RFN1VWM2STFTR part numbers?

A: The part numbers differ only in the suffix designation (STR versus STFTR). Both parts share the same base product number RFN1VWM2 and are manufactured by Rohm Semiconductor with identical electrical and mechanical specifications.

Q: Can these diodes be used in high-frequency switching applications?

A: Both parts are classified as fast recovery diodes with 25 ns reverse recovery time and fast recovery speed classification (≤ 500ns, > 200mA). This specification supports their use in switching applications within the specified voltage and current parameters.

Q: What is the maximum junction temperature for these components?

A: The maximum operating junction temperature for both RFN1VWM2STR and RFN1VWM2STFTR is 175°C.
