SFF2004GHC0G Equivalent & Substitute Parts

Part Overview

The SFF2004GHC0G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200V DC reverse voltage and 20A average rectified current. This through-hole component features fast recovery characteristics with a reverse recovery time of 35 nanoseconds, making it suitable for standard rectification applications requiring automotive-grade reliability. The device is actively produced and maintains full compliance with RoHS3 and AEC-Q101 automotive qualification standards. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when packaging preferences differ.

Substitute Part Grouping Explanation

Substitute parts for the SFF2004GHC0G are identified based on electrical and mechanical parameter equivalence. The substitution logic requires that alternative parts maintain identical specifications across the following critical parameters:

Voltage - DC Reverse (Vr) (Max): 200V
Current - Average Rectified (Io): 20A
Voltage - Forward (Vf) (Max) @ If: 975 mV @ 10A
Reverse Recovery Time (trr): 35 ns
Current - Reverse Leakage @ Vr: 10 µA @ 200V
Capacitance @ Vr, F: 90 pF @ 4V, 1MHz
Package / Case: TO-220-3 Full Pack, Isolated Tab
Mounting Type: Through Hole
Operating Temperature - Junction: -55°C to 150°C
Automotive Grade and AEC-Q101 Qualification

Parts meeting these criteria are classified as parametric equivalents and may be used interchangeably in circuit designs where the SFF2004GHC0G is specified. Differences in packaging format (such as tube versus full pack) do not affect electrical compatibility but may influence procurement and handling procedures.

Engineering Selection Recommendations

Both the SFF2004GHC0G and SFF2004G are active products manufactured by Taiwan Semiconductor Corporation with identical electrical characteristics and mechanical specifications. Selection between these parts should be based on the following criteria:

SFF2004GHC0G is specified with automotive-grade qualification (AEC-Q101) and is suitable for applications requiring formal automotive compliance documentation and traceability.

SFF2004G provides equivalent electrical performance and is available in tube packaging, offering flexibility for high-volume procurement scenarios where packaging format preferences differ from full pack configurations.

Both parts maintain full RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and REACH unaffected status. The choice between these substitutes does not compromise circuit performance, thermal characteristics, or regulatory compliance when applied within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SFF2004G be used as a direct replacement for SFF2004GHC0G?

A: Yes. Both parts share identical electrical specifications including voltage rating (200V), current rating (20A), forward voltage drop (975 mV @ 10A), and reverse recovery time (35 ns). The primary difference is packaging format: SFF2004GHC0G is supplied in full pack configuration while SFF2004G is supplied in tube packaging. Both use the same ITO-220AB package footprint and mounting method.

Q: What is the significance of the automotive grade designation on SFF2004GHC0G?

A: The automotive grade designation and AEC-Q101 qualification indicate that SFF2004GHC0G has undergone additional testing and validation required for automotive applications. This certification is mandatory for components used in automotive systems. SFF2004G does not carry this designation in the provided specifications.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and maintain the same thermal and electrical characteristics. Reverse recovery time, leakage current, and capacitance specifications are identical.

Q: Does packaging format affect circuit compatibility?

A: No. Packaging format (full pack versus tube) affects only procurement, handling, and storage procedures. The electrical and mechanical interface remains unchanged. Both parts use TO-220-3 Full Pack with isolated tab configuration and are mounted through-hole.

Q: Are both parts RoHS compliant?

A: Yes. Both SFF2004GHC0G and SFF2004G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
