Key Parameters

Substitute Part Grouping Explanation

Substitution of the HERAF1008G C0G is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The critical parameters establishing substitution eligibility are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 10 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 10 A
• Reverse Recovery Time (trr): 80 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 1000 V
• Capacitance @ Vr, F: 60 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack
• Operating Temperature - Junction: -55°C to 150°C

Substitute parts must match all specified electrical and mechanical parameters to ensure functional equivalence and direct replacement capability without circuit redesign or thermal management modifications.

Parameter Comparison

Engineering Selection Recommendations

The HERAF1008G substitute part is electrically and mechanically equivalent to the HERAF1008G C0G main part across all specified parameters. Both components are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical characteristics including reverse voltage rating, forward voltage drop, reverse recovery time, and leakage current specifications.

The primary distinction between the two parts is product status and packaging format. The HERAF1008G C0G is discontinued at DiGi Electronics, while the HERAF1008G remains active with higher inventory availability (3246 pieces versus 1192 pieces). The substitute part is supplied in tube packaging rather than the unspecified packaging of the main part.

Both parts satisfy identical compliance requirements: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level is equivalent at MSL 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

For applications currently utilizing the HERAF1008G C0G, direct substitution with the HERAF1008G is supported without circuit modification, thermal redesign, or performance degradation. The active product status and superior inventory availability of the substitute part make it the preferred selection for new procurement and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the HERAF1008G directly replace the HERAF1008G C0G in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including voltage rating (1000 V), current rating (10 A), forward voltage (1.7 V @ 10 A), reverse recovery time (80 ns), and package type (TO-220-2 through-hole). No circuit modifications are required.

Q: What is the difference between the HERAF1008G C0G and HERAF1008G?

A: The parts are electrically identical. The primary differences are product status (discontinued versus active) and packaging format (unspecified versus tube). The HERAF1008G offers superior inventory availability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, EAR99 export classification, and MSL 1 moisture sensitivity level.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range is -55°C to 150°C for both parts.

Q: What packaging options are available?

A: The HERAF1008G C0G packaging is unspecified in the provided data. The HERAF1008G substitute is supplied in tube packaging. Both use the TO-220-2 Full Pack case style with ITO-220AC supplier device package designation.

Q: What is the reverse recovery time specification?

A: The reverse recovery time (trr) is 80 ns for both parts, classifying them as fast recovery diodes with recovery time ≤ 500 ns at currents > 200 mA.

Q: Are these parts suitable for high-frequency switching applications?

A: These are standard technology rectifier diodes with 80 ns reverse recovery time. They are classified as fast recovery devices but are designed for general-purpose rectification rather than high-frequency switching applications.

Q: What is the reverse leakage current specification?

A: The reverse leakage current is 10 µA at the maximum reverse voltage rating of 1000 V for both parts.
