RFN10BM6STL Equivalent & Substitute Parts

Part Overview

The RFN10BM6STL is a general-purpose rectifier diode manufactured by Rohm Semiconductor, rated for 600 V DC reverse voltage and 10 A average rectified current in a Surface Mount TO-252 package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences while maintaining the same functional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RFN10BM6STL are identified based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Secondary Compatibility Factors:

• Current - Average Rectified (Io): 10 A (parametric equivalent) or lower (similar/derated)
• Reverse Recovery Time (trr): 50 ns (fast recovery classification)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Parts are grouped into two categories: Parametric Equivalent (identical electrical ratings and packaging) and Similar (same voltage and package with reduced current rating or modified thermal specifications).

Parameter Comparison

Engineering Selection Recommendations

RFN10BGE6STL (Parametric Equivalent Substitute)

The RFN10BGE6STL is a direct parametric equivalent to the RFN10BM6STL. Both components are manufactured by Rohm Semiconductor with identical electrical specifications: 600 V reverse voltage, 10 A average rectified current, 1.55 V forward voltage at 10 A, and 50 ns reverse recovery time. Both are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity. The primary difference is the packaging format: RFN10BM6STL is supplied in Cut Tape (CT) & Digi-Reel® format, while RFN10BGE6STL is supplied in Tape & Reel (TR) format. Both use the TO-252-3 DPAK package. This substitute is suitable for direct replacement in applications where the packaging format change is acceptable.

STTH506B-TR (Similar Substitute)

The STTH506B-TR is manufactured by STMicroelectronics and shares the same 600 V reverse voltage rating and TO-252-3 DPAK package as the RFN10BM6STL. However, this component has a reduced average rectified current rating of 5 A compared to the 10 A rating of the main part. The forward voltage is 1.85 V at 5 A, and the reverse recovery time is 50 ns. The operating temperature maximum is 175°C, which is 25°C higher than the RFN10BM6STL. This component is RoHS3 compliant with MSL 1 (Unlimited). The STTH506B-TR is suitable for applications where the current requirement does not exceed 5 A and the higher junction temperature rating is beneficial.

All substitute parts maintain Active product status and full regulatory compliance (RoHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can RFN10BGE6STL be used as a direct replacement for RFN10BM6STL?

A: Yes. Both parts have identical electrical specifications (600 V, 10 A, 1.55 V forward voltage, 50 ns recovery time) and use the same TO-252-3 DPAK package. The difference is packaging format: Cut Tape & Digi-Reel® versus Tape & Reel. Both are RoHS3 compliant with MSL 1 (Unlimited).

Q: What are the limitations of using STTH506B-TR as a substitute?

A: The STTH506B-TR has a maximum average rectified current of 5 A, compared to 10 A for the RFN10BM6STL. This part is suitable only for applications where the circuit current requirement does not exceed 5 A. The forward voltage is also higher at 1.85 V @ 5 A versus 1.55 V @ 10 A. The junction temperature rating is higher at 175°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RFN10BGE6STL, STTH506B-TR, and the main part RFN10BM6STL are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference between TO-252 and TO-252GE package designations?

A: Both designations refer to the same physical TO-252-3 DPAK (2 Leads + Tab) SC-63 package. The "GE" suffix in TO-252GE indicates a specific supplier device package variant used by Rohm Semiconductor for the RFN10BGE6STL, while the standard TO-252 designation is used for the RFN10BM6STL. The packages are mechanically and electrically compatible.

Q: Can STTH506B-TR be used in a 10 A application?

A: No. The STTH506B-TR is rated for a maximum average rectified current of 5 A. Using this part in a 10 A application would exceed its current rating and result in component failure or degraded performance.

Q: What is the reverse recovery time specification and why is it important?

A: Reverse recovery time (trr) is 50 ns for all three parts. This parameter defines how quickly the diode transitions from conducting to blocking state. The fast recovery classification (≤ 500ns, > 200mA) indicates these are fast recovery diodes suitable for high-frequency switching applications.

Q: Are there inventory differences between the substitute parts?

A: Yes. RFN10BM6STL has 2508 pcs in stock, RFN10BGE6STL has 3097 pcs in stock, and STTH506B-TR has 9778 pcs in stock. Inventory levels may influence part selection based on supply chain requirements.
