• Voltage - Forward (Vf) (Max) @ If: 930 mV @ 1 A
• Reverse Recovery Time (trr): 25 ns
• Current - Reverse Leakage @ Vr: 1 µA @ 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: 175°C

Mechanical Parameters:

• Package / Case: 2-SMD, Flat Lead
• Supplier Device Package: PMDE
• Mounting Type: Surface Mount

Compliance Parameters:

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

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

Parameter Comparison

Engineering Selection Recommendations

Both RFN1VWM2STFTR and RFN1VWM2STR are Active products from Rohm Semiconductor with identical electrical and mechanical specifications. Selection between these parts is based on packaging format and inventory availability rather than functional differences.

RFN1VWM2STFTR is supplied in Tape & Reel (TR) format with 2468 pieces currently in stock. This packaging format is standard for automated assembly operations and high-volume production environments.

RFN1VWM2STR is supplied in Tape & Reel (TR) format with 1607 pieces currently in stock. This part number represents an alternative tape and reel configuration within the same product family.

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), making them suitable for applications requiring regulatory compliance. The selection between these equivalent parts should be based on procurement requirements, assembly process compatibility, and current inventory levels.

Frequently Asked Questions (FAQ)

Q: Are RFN1VWM2STFTR and RFN1VWM2STR electrically identical?

A: Yes. Both parts share identical electrical specifications including 200 V reverse voltage rating, 1 A average rectified current, 930 mV forward voltage drop at 1 A, 25 ns reverse recovery time, and 1 µA reverse leakage current at 200 V.

Q: What is the difference between these two part numbers?

A: The primary difference is the packaging designation within the Tape & Reel (TR) format. Both parts use the same PMDE surface mount package with 2-SMD flat lead configuration. The suffix variation (STFTR vs. STR) indicates different tape and reel specifications from the manufacturer.

Q: Can I substitute RFN1VWM2STR for RFN1VWM2STFTR in my design?

A: Yes. Both parts are parametric equivalents with matching electrical performance, mechanical compatibility, and compliance certifications. Substitution is valid for applications requiring 200 V, 1 A general-purpose rectification in surface mount PMDE packages.

Q: Are there any temperature or thermal differences between these parts?

A: No. Both parts have identical maximum junction operating temperature of 175°C and identical thermal characteristics.

Q: What packaging format do these parts use?

A: Both parts are supplied in Tape & Reel (TR) format with surface mount PMDE package configuration. The 2-SMD flat lead design is compatible with standard automated pick-and-place assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RFN1VWM2STFTR and RFN1VWM2STR are ROHS3 compliant with REACH unaffected status, suitable for applications requiring regulatory compliance in electronics manufacturing.

Q: What is the moisture sensitivity rating for these diodes?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without special moisture control requirements during storage and handling.
