Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SF1JDF-13 are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V

Mechanical Parameters (Must Match):

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

Regulatory & Compliance (Must Match):

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

Allowable Variations:

• Reverse Recovery Time (trr): Substitutes may exceed the main part specification (35 ns) up to 75 ns while maintaining fast recovery classification
• Capacitance @ Vr, F: Substitutes may vary (10 pF to 20 pF @ 4V, 1MHz)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats are interchangeable
• Automotive Grade and AEC-Q101 qualification are optional enhancements

Parameter Comparison

Engineering Selection Recommendations

SF1JDF-13 (Primary Part) Use when standard-grade rectifier diodes are specified and Tape & Reel packaging is required. This part maintains Active product status with full RoHS3 compliance and REACH unaffected designation.

US1JDF-13 (Direct Substitute) Use as a direct substitute when Tape & Reel packaging is required and standard-grade classification is acceptable. Electrical performance is equivalent with allowable variation in reverse recovery time (75 ns vs. 35 ns) and capacitance (10 pF vs. 20 pF). All regulatory compliance requirements are identical.

US1JDFQ-13 (Automotive-Grade Substitute) Use when automotive-grade qualification (AEC-Q101) is required or when Cut Tape & Digi-Reel® packaging format is preferred. This part provides enhanced reliability certification suitable for automotive applications while maintaining all core electrical and mechanical specifications. Reverse recovery time and capacitance parameters are identical to US1JDF-13.

All three parts are manufactured by Diodes Incorporated and maintain Active product status with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can US1JDF-13 be used as a direct replacement for SF1JDF-13? A: Yes. Both parts share identical electrical ratings (600 V, 1 A, 1.7 V forward voltage) and mechanical specifications (2-SMD D-Flat package, surface mount). The reverse recovery time difference (75 ns vs. 35 ns) remains within fast recovery classification. Regulatory compliance is equivalent.

Q: What is the difference between US1JDF-13 and US1JDFQ-13? A: The primary differences are packaging format and automotive qualification. US1JDF-13 is supplied in Tape & Reel format with standard-grade classification. US1JDFQ-13 is supplied in Cut Tape & Digi-Reel® format and carries AEC-Q101 automotive qualification. Electrical specifications are identical.

Q: Does the 40 ns difference in reverse recovery time (35 ns vs. 75 ns) affect circuit performance? A: Both parts meet the fast recovery classification (≤ 500 ns, > 200 mA). The difference is allowable within the specified parameter range for this product category. Circuit-level impact depends on application-specific switching frequency and load requirements.

Q: Are all three parts RoHS3 compliant? A: Yes. SF1JDF-13, US1JDF-13, and US1JDFQ-13 are all ROHS3 compliant with REACH unaffected status.

Q: Can I substitute SF1JDF-13 with US1JDFQ-13 if my design does not require automotive qualification? A: Yes. US1JDFQ-13 meets or exceeds all electrical and mechanical requirements of SF1JDF-13. Automotive qualification is an additional feature that does not prevent use in non-automotive applications. Packaging format difference (Cut Tape & Digi-Reel® vs. Tape & Reel) must be accommodated in procurement and assembly processes.

Q: What is the significance of the capacitance difference (20 pF vs. 10 pF)? A: Capacitance variation is allowable within the specified parameter range. The 10 pF rating of US1JDF-13 and US1JDFQ-13 represents lower junction capacitance, which may provide marginal benefits in high-frequency switching applications. Both values are acceptable for general-purpose rectification.

Q: Are there inventory considerations when selecting between these parts? A: Yes. Inventory levels differ: SF1JDF-13 (902 Pcs), US1JDF-13 (9,861 Pcs), and US1JDFQ-13 (260,200 Pcs). Availability should be evaluated based on project timeline and volume requirements.
