Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the US2JDF-13 are identified based on strict equivalence of the following critical parameters:

• Voltage Rating: 600 V DC reverse voltage (Vr) maximum
• Current Rating: 2 A average rectified current (Io)
• Package Type: 2-SMD, Flat Lead surface mount configuration
• Speed Classification: Fast Recovery diode technology
• Temperature Range: -55°C to 150°C junction operating temperature
• Compliance: RoHS3 compliant, REACH unaffected status
• Moisture Sensitivity: MSL 1 (Unlimited)

The SF2JDF-13 meets all substitution criteria within the allowed parameter tolerance for this product category. Both parts share identical voltage and current ratings, package configuration, and compliance certifications. Variations in forward voltage measurement conditions (1 A vs. 2 A), reverse recovery time (75 ns vs. 35 ns), and junction capacitance (10 pF vs. 50 pF) remain within acceptable ranges for general-purpose rectification applications and do not preclude functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the US2JDF-13 and SF2JDF-13 are Active product status components manufactured by Diodes Incorporated with identical RoHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements within the following framework:

US2JDF-13 is selected when:

• Standard reverse recovery time performance (75 ns) is acceptable
• Lower junction capacitance (10 pF) is preferred for high-frequency switching applications
• Forward voltage measurement at 1 A operating point aligns with circuit design parameters

SF2JDF-13 is selected when:

• Faster reverse recovery time (35 ns) is required for improved switching efficiency
• Higher junction capacitance (50 pF) does not degrade circuit performance
• Forward voltage measurement at 2 A operating point aligns with circuit design parameters

Both parts maintain identical voltage and current ratings, package configuration, and thermal operating range. Substitution is valid for general-purpose rectification applications where the specified parameter variations do not impact circuit functionality or performance requirements.

Frequently Asked Questions (FAQ)

Q: Can SF2JDF-13 be used as a direct replacement for US2JDF-13?

A: Yes. Both parts share identical voltage ratings (600 V), current ratings (2 A), package configuration (2-SMD, Flat Lead), and compliance certifications (RoHS3, REACH unaffected). The SF2JDF-13 exhibits faster reverse recovery time (35 ns vs. 75 ns) and higher junction capacitance (50 pF vs. 10 pF), which are compatible with general-purpose rectification applications.

Q: What is the difference in reverse recovery time between these parts?

A: The US2JDF-13 has a reverse recovery time of 75 ns, while the SF2JDF-13 has 35 ns. The SF2JDF-13 exhibits faster switching characteristics, which may reduce switching losses in high-frequency applications. Both parts meet the Fast Recovery classification (≤ 500 ns, > 200 mA).

Q: Are the forward voltage specifications identical?

A: Forward voltage is specified at different measurement conditions. US2JDF-13 is rated at 1.7 V maximum at 1 A, while SF2JDF-13 is rated at 1.7 V maximum at 2 A. Both maintain the same maximum forward voltage value, with measurement conditions reflecting their respective current ratings.

Q: Do these parts have the same package footprint?

A: Yes. Both US2JDF-13 and SF2JDF-13 use the 2-SMD, Flat Lead package configuration (D-Flat supplier device package), ensuring identical PCB footprint and assembly compatibility.

Q: What is the junction capacitance difference, and does it matter?

A: US2JDF-13 has 10 pF junction capacitance at 4 V, 1 MHz, while SF2JDF-13 has 50 pF. Lower capacitance (US2JDF-13) is preferred in high-frequency switching circuits to minimize parasitic effects. Higher capacitance (SF2JDF-13) may be acceptable in lower-frequency applications where capacitive reactance is not a limiting factor.

Q: Are both parts RoHS3 compliant?

A: Yes. Both US2JDF-13 and SF2JDF-13 are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications for industrial and commercial applications.
