Substitute Part Grouping Explanation

Substitution of the SF802GHC0G is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 8 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 100 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Environmental Parameters (Must Match):

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

Compliance & Qualification (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Substitute parts identified below maintain identical electrical performance, thermal operating range, and automotive qualification status. Differences in diode configuration (single diode versus diode array) are noted where applicable and do not affect functional substitution in single-diode circuit applications.

Engineering Selection Recommendations

SF802GH (Direct Manufacturer Substitute): This part is the primary substitute for the discontinued SF802GHC0G. Both components share identical electrical specifications, thermal operating range, and automotive qualification. The SF802GH is configured as a 1-pair common cathode diode array within the same TO-220-3 package. For single-diode applications, one diode element of the SF802GH array provides direct functional equivalence. This part maintains active product status and is currently in stock, ensuring supply continuity. All compliance certifications (AEC-Q101, ROHS3) are maintained.

SF802GC0G (Parametric Equivalent): This part provides complete parametric equivalence to the SF802GHC0G across all critical electrical and thermal specifications. The SF802GC0G is a single general-purpose diode (not an array configuration) with identical voltage ratings, current capacity, recovery time, and leakage characteristics. This part is active and maintains higher inventory availability. The SF802GC0G is suitable for direct replacement in applications where single-diode functionality is required. All automotive-grade qualifications and compliance standards are identical.

Both substitute parts eliminate supply discontinuity while maintaining full electrical and environmental performance equivalence to the original SF802GHC0G specification.

Frequently Asked Questions (FAQ)

Q: Can the SF802GH (diode array) be used as a direct replacement for the SF802GHC0G (single diode)?

A: Yes. The SF802GH contains a 1-pair common cathode diode array in the same TO-220-3 package. For single-diode circuit applications, one diode element of the array provides identical electrical performance. The unused diode element remains available for alternative circuit configurations or can be left unconnected.

Q: Are the electrical specifications identical between SF802GHC0G and both substitute parts?

A: The SF802GHC0G and SF802GC0G share identical electrical specifications across all critical parameters: 100 V reverse voltage, 8 A average rectified current, 35 ns reverse recovery time, and 10 µA reverse leakage. The SF802GH maintains these same specifications per diode element. Forward voltage specifications differ slightly in test conditions (SF802GH measured at 4 A versus 8 A for the other parts), but all three parts meet the 975 mV maximum forward voltage specification.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. All three parts (SF802GHC0G, SF802GH, and SF802GC0G) carry automotive-grade classification with AEC-Q101 qualification. All are ROHS3 compliant and suitable for automotive and industrial applications.

Q: What is the difference between the SF802GH and SF802GC0G?

A: The SF802GH is a diode array with 1-pair common cathode configuration, while the SF802GC0G is a single general-purpose diode. Both are housed in TO-220-3 packages and provide identical electrical performance. The choice between them depends on circuit design requirements: the array configuration of SF802GH may offer flexibility for dual-diode applications, while the SF802GC0G provides a single-diode solution.

Q: Are the TO-220-3 packages physically identical?

A: Yes. All three parts use the TO-220-3 through-hole package with identical physical dimensions and pin configuration, ensuring direct mechanical compatibility in existing PCB layouts and thermal management designs.

Q: What is the current product availability status?

A: The SF802GHC0G is discontinued at DiGi Electronics. Both substitute parts (SF802GH and SF802GC0G) maintain active product status with current inventory availability, ensuring supply continuity for new designs and production requirements.
