Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFF1001GAHC0G is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io) (per Diode): 10 A (DC)
• Voltage - Forward (Vf) (Max) @ If: 975 mV @ 5 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 50 V
• Operating Temperature - Junction: -55°C ~ 150°C

Mechanical Parameters (Must Match):

• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Mounting Type: Through Hole

Configuration Parameter (Application-Dependent):

• Diode Configuration: 1 Pair Common Anode or 1 Pair Common Cathode

Substitute parts are grouped into two categories based on diode configuration. Common Anode substitutes maintain identical circuit topology. Common Cathode substitutes require circuit redesign but provide electrical equivalence when reconfigured.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement):

SFF1001GAH is the recommended direct substitute for SFF1001GAHC0G. Both parts share identical electrical specifications, diode configuration (1 Pair Common Anode), automotive grade designation, and AEC-Q101 qualification. SFF1001GAH is currently active in production with 1191 units in stock, ensuring supply continuity. No circuit redesign is required.

Secondary Substitutes (Configuration-Dependent):

SFF1001GA C0G and SFF1001G C0G are electrically equivalent alternatives with identical voltage, current, and thermal ratings. However, these parts differ in diode configuration. SFF1001GA C0G maintains Common Anode configuration but lacks specified automotive grade and AEC-Q101 qualification. SFF1001G C0G and SFF1001GHC0G feature Common Cathode configuration, requiring circuit topology modification. SFF1001GHC0G retains automotive grade and AEC-Q101 qualification despite configuration change.

Compliance Considerations:

For applications requiring automotive qualification and AEC-Q101 compliance, SFF1001GAH and SFF1001GHC0G are the only active substitutes meeting these criteria. SFF1001GA C0G and SFF1001G C0G lack specified automotive grade and qualification status, making them unsuitable for regulated automotive applications.

Frequently Asked Questions (FAQ)

Q: Can SFF1001GAH directly replace SFF1001GAHC0G without circuit modification?

A: Yes. SFF1001GAH is a direct substitute with identical electrical parameters, diode configuration, package, and automotive qualifications. No circuit redesign is required.

Q: What is the difference between Common Anode and Common Cathode configurations?

A: Common Anode configuration connects the anode terminals of both diodes to a single node. Common Cathode configuration connects the cathode terminals to a single node. These configurations determine circuit topology and cannot be interchanged without redesigning the circuit connections.

Q: Are SFF1001GA C0G and SFF1001G C0G suitable for automotive applications?

A: SFF1001GA C0G and SFF1001G C0G lack specified automotive grade and AEC-Q101 qualification in the provided data. For applications requiring automotive compliance, use SFF1001GAH or SFF1001GHC0G.

Q: Does the TO-220-3 Full Pack with isolated tab package differ between substitute parts?

A: No. All substitute parts use identical TO-220-3 Full Pack with isolated tab through-hole packaging, ensuring mechanical compatibility and identical PCB footprint.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Voltage - DC Reverse (50 V), Current - Average Rectified (10 A per diode), Forward Voltage (975 mV @ 5 A), Reverse Recovery Time (35 ns), Reverse Leakage Current (10 µA @ 50 V), and Operating Temperature Range (-55°C ~ 150°C) must remain constant across all substitutes.

Q: Is SFF1001GHC0G a viable substitute if circuit redesign is acceptable?

A: Yes. SFF1001GHC0G provides electrical equivalence with identical voltage, current, and thermal specifications. It maintains automotive grade and AEC-Q101 qualification. Circuit redesign is required due to Common Cathode configuration, but electrical performance remains equivalent.
