Package / Case: TO-220-3

Allowable Variation Parameters:

Current - Average Rectified (Io) (per Diode): Equal to or greater than 10 A
Voltage - Forward (Vf) (Max) @ If: Lower values are acceptable
Speed: Fast Recovery (≤500ns) is acceptable as an upgrade from Standard Recovery (>500ns)
Current - Reverse Leakage @ Vr: Higher values are acceptable within design tolerance
Operating Temperature - Junction: Range must encompass or exceed -55°C to 150°C
Technology: Standard or Super Barrier technologies are both acceptable

All substitute parts listed maintain the TO-220-3 through-hole package and 100 V reverse voltage specification. Current ratings range from 5 A to 30 A, providing options for designs requiring additional margin or higher performance. Technology variants include both Standard and Super Barrier diode types.

Engineering Selection Recommendations

Direct Electrical Equivalents (Same Current Rating):

SBR20E100CT and SBR20U100CT both provide 10 A current rating matching the GP1002HC0G. SBR20E100CT maintains Standard Recovery speed characteristics identical to the original part, while SBR20U100CT offers Fast Recovery technology with improved switching performance. Both are manufactured by Diodes Incorporated and maintain full RoHS3 compliance and REACH Unaffected status. SBR20U100CT is preferred for applications where lower forward voltage drop (700 mV vs. 1.1 V) and faster recovery time provide design benefits.

Higher Current Rating Substitutes:

BYV32-100-E3/45 (18 A), FEP16BT-E3/45 (16 A), SBR30A100CT (15 A), SBR40100CT (20 A), and SBR60A100CT (30 A) provide increased current capacity. These parts are suitable for designs requiring additional thermal or electrical margin. All maintain 100 V reverse voltage specification and TO-220-3 packaging. SBR30A100CT, SBR40100CT, and SBR60A100CT offer Super Barrier technology with significantly reduced forward voltage characteristics.

Lower Current Rating Substitute:

SBR10U100CT (5 A) is available for applications with reduced current requirements. This part features Super Barrier technology with the lowest forward voltage drop (670 mV @ 5 A) among all listed substitutes.

Compliance and Availability:

All listed substitute parts maintain active product status with the exception of SBR30100CT, which is marked obsolete. All active substitutes are RoHS3 compliant and REACH Unaffected. Inventory availability ranges from 1379 to 27913 units across substitute options.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the GP1002HC0G?

A: Yes. A substitute part with equal or greater current rating (Io) is electrically compatible. Higher current ratings provide additional design margin and thermal headroom. The 100 V reverse voltage specification and TO-220-3 package must remain unchanged.

Q: What is the difference between Standard Recovery and Fast Recovery diodes?

A: Standard Recovery diodes have reverse recovery time greater than 500 ns, while Fast Recovery diodes have reverse recovery time of 500 ns or less. Fast Recovery diodes reduce switching losses and electromagnetic interference in high-frequency applications. Both types are functionally compatible in the GP1002HC0G application.

Q: What is Super Barrier technology?

A: Super Barrier is a diode technology that reduces forward voltage drop compared to standard rectifier diodes. SBR-series parts (SBR10U100CT, SBR20E100CT, SBR20U100CT, SBR30A100CT, SBR40100CT, SBR60A100CT) incorporate this technology, offering lower power dissipation and improved efficiency.

Q: Are all substitute parts automotive qualified?

A: The GP1002HC0G carries AEC-Q101 automotive qualification. Substitute parts from Vishay and Diodes Incorporated maintain equivalent automotive-grade reliability standards and RoHS3 compliance, though specific AEC-Q101 certification should be verified with the manufacturer for critical automotive applications.

Q: Can I use SBR10U100CT as a substitute if my design only requires 5 A?

A: Yes. SBR10U100CT is electrically compatible with the GP1002HC0G. The lower current rating does not prevent substitution; however, this part would be underutilized in a 10 A application. For 10 A designs, SBR20E100CT or SBR20U100CT are more appropriate selections.

Q: What is the difference between BYV32-100-E3/45 and the GP1002HC0G?

A: BYV32-100-E3/45 provides 18 A current capacity versus 10 A for the GP1002HC0G, operates at -65°C to 150°C versus -55°C to 150°C, and features Fast Recovery technology. Both maintain 100 V reverse voltage and TO-220-3 packaging. BYV32-100-E3/45 is suitable for applications requiring higher current or extended low-temperature operation.

Q: Is the TO-220-3 package identical across all substitute parts?

A: Yes. All listed substitute parts use the TO-220-3 through-hole package, ensuring mechanical and thermal compatibility with the GP1002HC0G. Pin configuration and mounting requirements remain unchanged.

Q: What does RoHS3 compliance mean?

A: RoHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part contains no lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers above specified thresholds. All listed substitute parts maintain RoHS3 compliance.
