Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SR810HA0G are selected based on strict electrical and mechanical compatibility criteria. All substitute diodes must meet the following requirements:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100V minimum
• Package / Case: DO-201AD, Axial through-hole configuration
• Technology: Schottky rectifier diode
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Mounting Type: Through Hole

Current Rating Consideration: Substitute parts may have lower average rectified current ratings than the main part (8A), provided the substitute meets or exceeds the application's actual current requirement. Parts with current ratings below 8A are suitable for applications requiring less than their rated current capacity.

Reverse Leakage Tolerance: Substitute parts may exhibit higher reverse leakage current than the main part, within acceptable limits for the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

SR810HA0G (Main Part): The SR810HA0G is the primary selection for applications requiring 8A average rectified current at 100V reverse voltage. This part carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. The part is active and in stock with 921 units available.

SB3100-T (Diodes Incorporated): The SB3100-T is suitable for applications requiring 3A or less average rectified current at 100V reverse voltage. This substitute provides a lower current rating and is appropriate for reduced-current circuit designs. The part is ROHS3 compliant and REACH unaffected. Operating temperature range extends to -65°C, providing wider low-temperature operation than the main part. Inventory availability is 1232 units.

SB5100-T (Diodes Incorporated): The SB5100-T is suitable for applications requiring 5A average rectified current at 100V reverse voltage. This substitute bridges the current rating gap between the 3A and 8A options. The part is ROHS3 compliant and REACH unaffected. Operating temperature range extends to -65°C. Inventory availability is 3773 units, providing the highest stock level among all options.

All substitute parts maintain identical package configuration (DO-201AD axial through-hole), fast recovery switching characteristics, and regulatory compliance status. Selection between substitutes depends on the actual current requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can SB3100-T or SB5100-T be used as direct replacements for SR810HA0G?

A: SB3100-T and SB5100-T are suitable substitutes only when the application circuit requires 3A or 5A average rectified current respectively. Both parts share identical reverse voltage rating (100V), package configuration (DO-201AD axial), and fast recovery switching characteristics. If the circuit design requires the full 8A capacity of the SR810HA0G, these lower-current substitutes are not appropriate.

Q: What are the key differences between the substitute parts?

A: The primary difference is average rectified current rating: SB3100-T is rated for 3A, while SB5100-T is rated for 5A. Both exhibit identical reverse voltage (100V), package type (DO-201AD), and switching speed characteristics. Forward voltage drop differs slightly between parts due to different current ratings. Reverse leakage current is higher in both substitutes (500 µA) compared to the main part (100 µA).

Q: Are all parts compatible with the same PCB footprint?

A: Yes. All three parts use the DO-201AD axial through-hole package, which provides identical mechanical dimensions and PCB pad spacing. No PCB redesign is required when substituting between these parts.

Q: Do the substitute parts meet automotive qualification requirements?

A: The SR810HA0G carries AEC-Q101 automotive qualification. The substitute parts SB3100-T and SB5100-T do not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring AEC-Q101 certification, the SR810HA0G is the appropriate selection.

Q: What is the impact of higher reverse leakage current in the substitute parts?

A: The substitute parts exhibit 500 µA reverse leakage at 100V compared to 100 µA in the main part. This difference must be evaluated within the specific circuit design. Applications with high-impedance input stages or precision analog circuits may be sensitive to this parameter difference.

Q: Can these parts be used interchangeably in high-current applications?

A: No. The SB3100-T and SB5100-T have lower current ratings than the SR810HA0G. Using a lower-rated part in a circuit designed for 8A operation will result in excessive junction temperature and potential device failure. Current rating selection must match or exceed the application requirement.

Q: What is the operating temperature range difference?

A: The SR810HA0G operates from -55°C to 150°C junction temperature. Both substitute parts extend the lower temperature limit to -65°C, providing 10°C additional cold-temperature operation capability. The upper temperature limit remains 150°C for all parts.
