RFN10B3STL Equivalent & Substitute Parts Reference

Part Overview

The RFN10B3STL from Rohm Semiconductor is a general-purpose surface-mount fast recovery diode rated for 350 V reverse voltage and 10 A average rectified current. It is supplied in a TO-252-3, DPAK (2 Leads + Tab), SC-63 package. The diode is classified as standard technology, with a fast recovery time of 30 ns and a maximum forward voltage of 1.5 V at 10 A. The product status is obsolete, making identification of electrical and mechanical substitutes necessary for ongoing designs and maintenance purposes.

Substitute Part Grouping Explanation

Equivalent and substitute parts are selected based exclusively on the following electrical and mechanical parameters:

Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io)
Voltage - Forward (Vf) (Max) @ If
Speed / Reverse Recovery Time (trr)
Current - Reverse Leakage @ Vr
Mounting Type
Package / Case
RoHS and REACH compliance
Operating Temperature - Junction

Only parts that match or closely align with these criteria, as explicitly provided, are listed here. Substitute relationships are determined by matching these parameters strictly; package compatibility and electrical characteristics are adhered to without deviation.

Engineering Selection Recommendations

The RFN10B3STL is obsolete. Both RFN10BM3SFHTL and RFN10BM3STL from Rohm Semiconductor are active, meet identical electrical and mechanical parameters, and maintain ROHS3 and REACH compliance with unlimited MSL. The VS-8EWF04S-M3 from Vishay General Semiconductor - Diodes Division is also active, shares the same package type, and has ROHS3 and REACH status; however, it differs in maximum voltage, current rating, forward voltage, and reverse recovery time, and would be classified as a similar rather than a parametric equivalent option based on the provided parameters.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical when substituting the RFN10B3STL?
A1: Critical parameters include voltage - DC reverse (Vr), current - average rectified (Io), voltage - forward (Vf) at If, reverse recovery time (trr), reverse leakage current at Vr, mounting type, package/case, and RoHS/REACH compliance.

Q2: Can parts with higher voltage or current ratings be used as substitutes?
A2: Only parts matching the listed parameters are considered substitutes. The VS-8EWF04S-M3 presents a higher voltage but lower current rating and is only categorized as similar, not equivalent.

Q3: Is package compatibility assured among listed substitutes?
A3: All listed equivalents utilize the TO-252-3, DPAK (2 Leads + Tab), SC-63 surface mount package, matching the original part’s mechanical interface.

Q4: Are there any differences in compliance or qualification?
A4: All fully equivalent listed parts are ROHS3 compliant and REACH unaffected with MSL 1 (unlimited). Grade and qualification details are only present for some Rohm alternatives where specified.

Q5: What is the status of each substitute part?
A5: Both RFN10BM3SFHTL and RFN10BM3STL are active parts and fully parametric equivalents; the VS-8EWF04S-M3 is active but similar rather than equivalent.
