Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the US1JDF-13 rectifier diode is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
• Operating Temperature - Junction: -55°C to 150°C
• Package / Case: 2-SMD, Flat Lead
• Mounting Type: Surface Mount
• Technology: Standard
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Reverse Recovery Time (trr): Faster recovery times (lower values) are acceptable
• Capacitance @ Vr, F: Variations within the specified measurement conditions are acceptable
• Packaging Format: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® formats are interchangeable for the same electrical device
• Automotive Qualification: AEC-Q101 certification is an additional qualification that does not disqualify substitution

All identified substitute parts maintain identical electrical performance within the specified operating parameters and are compatible with existing PCB designs and assembly processes.

Engineering Selection Recommendations

US1JDF-13 (Primary Part) Select this part number for standard applications requiring 600 V, 1 A rectification in Tape & Reel packaging format. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Inventory availability is 9861 pieces.

SF1JDF-13 (Parametric Equivalent) This substitute offers identical electrical performance with improved reverse recovery time (35 ns versus 75 ns), resulting in faster switching characteristics. The part is suitable for applications where reduced switching losses are beneficial. Capacitance is higher at 20 pF. Tape & Reel packaging format is maintained. Inventory availability is 902 pieces. Select this part when faster recovery performance is required and inventory of the primary part is constrained.

US1JDFQ-13 (Parametric Equivalent with Automotive Qualification) This substitute maintains identical electrical specifications to the primary part and includes AEC-Q101 automotive qualification. The part is supplied in Cut Tape (CT) & Digi-Reel® packaging format, suitable for applications requiring individual component handling or automated dispensing systems. Inventory availability is 260200 pieces, providing the highest stock level. Select this part for automotive applications or when Cut Tape packaging format is required.

All three parts are manufactured by Diodes Incorporated and maintain Active product status with full RoHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can SF1JDF-13 be used as a direct replacement for US1JDF-13?

A: Yes. SF1JDF-13 is a parametric equivalent with identical voltage, current, and temperature ratings. The primary difference is faster reverse recovery time (35 ns versus 75 ns), which is a performance improvement. Both parts use identical 2-SMD, Flat Lead packaging and surface mount configuration.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape in reel format, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments or in Digi-Reel® format, suitable for lower-volume production or applications requiring individual component handling. Both formats contain identical electrical components.

Q: Is US1JDFQ-13 suitable for non-automotive applications?

A: Yes. US1JDFQ-13 maintains identical electrical specifications to US1JDF-13 and is fully compatible with non-automotive applications. The AEC-Q101 automotive qualification is an additional certification that does not restrict use in standard applications. This part offers the highest inventory availability at 260200 pieces.

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

A: Operating temperature range is identical across all three parts (-55°C to 150°C). SF1JDF-13 exhibits faster reverse recovery time (35 ns), which reduces switching losses in high-frequency applications. This represents improved performance rather than a limitation. Reverse leakage current and forward voltage are identical across all parts.

Q: Can these parts be mixed in the same assembly?

A: Yes. All three parts are electrically equivalent within the specified parameters and use identical 2-SMD, Flat Lead packaging. They are mechanically and electrically interchangeable on the same PCB design. Mixing parts in the same assembly does not create compatibility issues.

Q: What compliance certifications apply to all substitute parts?

A: All three parts maintain RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1). US1JDFQ-13 includes additional AEC-Q101 automotive qualification. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.
