Substitute Part Grouping Explanation

Substitute parts for the SFF2006G are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 20 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 10 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V
• Capacitance @ Vr, F: 90 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The SFF2006GH meets all substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

SFF2006G (Standard Grade)

The SFF2006G is suitable for general-purpose rectification applications where standard industrial compliance is required. This part maintains Active product status and full RoHS3 compliance.

SFF2006GH (Automotive Grade)

The SFF2006GH is electrically and mechanically identical to the SFF2006G with the addition of AEC-Q101 automotive qualification. This part is appropriate for applications requiring automotive-grade reliability and qualification documentation. Both parts share identical electrical performance and package specifications.

Selection between these parts depends on application requirements and qualification mandates rather than electrical or mechanical differences.

Frequently Asked Questions (FAQ)

Q: Can SFF2006GH replace SFF2006G in any application?

A: Yes. The SFF2006GH is a parametric equivalent with identical electrical and mechanical specifications. The SFF2006GH includes additional AEC-Q101 automotive qualification, making it suitable for all applications where SFF2006G is used.

Q: Can SFF2006G replace SFF2006GH?

A: Electrical and mechanical compatibility is confirmed. However, if AEC-Q101 automotive qualification is a design requirement, SFF2006G does not carry this certification and substitution is not appropriate for those applications.

Q: Are the packages identical?

A: Yes. Both parts use TO-220-3 Full Pack with isolated tab, through-hole mounting configuration. PCB layout and thermal management considerations are identical.

Q: What is the difference between these parts?

A: The only difference is qualification status. SFF2006GH carries AEC-Q101 automotive qualification; SFF2006G does not. All electrical parameters, thermal ratings, and compliance certifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SFF2006G and SFF2006GH are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the operating temperature range?

A: Both parts operate from -55°C to 150°C junction temperature.
