SFF1004GA Equivalent & Substitute Parts

Part Overview

The SFF1004GA is a diode array rectifier manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Anode device rated for 200 V DC reverse voltage and 10 A average rectified current per diode. The component features fast recovery characteristics with a 35 ns reverse recovery time and is housed in a TO-220-3 Full Pack with isolated tab through-hole package.

The SFF1004GA is currently discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and production needs. Alternative parts are available from the same manufacturer in both parametrically equivalent and similar configurations, as well as from alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFF1004GA is determined by the following critical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 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 @ 200 V
• Operating Temperature - Junction: -55°C ~ 150°C

Mechanical Parameters:

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

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts that match all electrical and mechanical specifications but may differ in diode configuration (Common Anode vs. Common Cathode) or include automotive-grade qualifications. These parts are direct functional replacements when circuit topology accommodates the configuration difference.

Similar Parts: Components from alternative manufacturers that meet the core electrical specifications and package requirements but may have variations in specific parameters or compliance status.

Engineering Selection Recommendations

For Direct Common Anode Configuration Replacement:

SFF1004GAHC0G is the primary substitute for SFF1004GA. This part maintains identical electrical specifications, the same Common Anode diode configuration, and the same package format. SFF1004GAHC0G is currently active in production with 691 units in stock. The addition of automotive-grade qualification (AEC-Q101) provides enhanced reliability for applications requiring automotive compliance, with no performance degradation for non-automotive applications.

For Common Cathode Configuration Applications:

SFF1004G and SFF1004GHC0G are suitable substitutes when circuit topology permits use of a Common Cathode configuration. SFF1004G is the standard industrial-grade version with 5130 units in stock and active product status. SFF1004GHC0G is the automotive-qualified variant (AEC-Q101) with 1092 units in stock. Both parts maintain all electrical specifications identical to the SFF1004GA.

For Alternative Manufacturer Requirement:

SDURF1020CT from SMC Diode Solutions meets the core electrical and mechanical specifications with Common Cathode configuration. This part is active with 1272 units in stock. Note that average rectified current per diode is not specified for this part. REACH status is listed as affected, requiring verification for applications subject to REACH compliance requirements.

Product Status Consideration:

All substitute parts listed are currently active in production, eliminating obsolescence risk associated with the discontinued SFF1004GA.

Frequently Asked Questions (FAQ)

Q: Can SFF1004G be used as a direct replacement for SFF1004GA?

A: SFF1004G is electrically equivalent to SFF1004GA with identical voltage, current, and thermal specifications. The primary difference is diode configuration: SFF1004G is Common Cathode while SFF1004GA is Common Anode. Substitution is possible only if the circuit design accommodates Common Cathode configuration. Verify pin connections in the application schematic before substitution.

Q: What is the difference between SFF1004GAHC0G and SFF1004GA?

A: SFF1004GAHC0G maintains the same Common Anode configuration and all electrical specifications as SFF1004GA. The primary difference is that SFF1004GAHC0G includes automotive-grade qualification (AEC-Q101), making it suitable for automotive applications. For non-automotive applications, both parts are functionally equivalent. SFF1004GAHC0G is currently active while SFF1004GA is discontinued.

Q: Can SDURF1020CT from SMC Diode Solutions replace SFF1004GA?

A: SDURF1020CT meets the voltage, temperature, and package specifications of SFF1004GA. However, SDURF1020CT uses Common Cathode configuration, requiring circuit topology verification. Additionally, average rectified current per diode is not specified for SDURF1020CT, and REACH status is listed as affected. Confirm these parameters with the supplier before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed (SFF1004G, SFF1004GAHC0G, SFF1004GHC0G, and SDURF1020CT) are ROHS3 compliant, matching the compliance status of SFF1004GA.

Q: What is the significance of the ITO-220AB package designation?

A: ITO-220AB is the supplier device package designation for the TO-220-3 Full Pack with isolated tab configuration. All substitute parts use the same ITO-220AB package, ensuring mechanical and thermal compatibility with existing PCB layouts and heat sink mounting arrangements.

Q: Does diode configuration affect thermal performance?

A: Diode configuration (Common Anode vs. Common Cathode) does not affect thermal performance. All parts listed operate within the same temperature range (-55°C ~ 150°C junction temperature) and use identical package geometry. Thermal performance is determined by the TO-220-3 package and isolated tab design, which are consistent across all substitute options.

Q: Why is average rectified current not specified for SDURF1020CT?

A: The provided data for SDURF1020CT does not include average rectified current specification. This parameter must be obtained from the SMC Diode Solutions datasheet before confirming substitution for applications with specific current requirements.
