Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH2002CG is determined by the following critical parameters:

1. Diode Configuration: Must be 1 pair common cathode to maintain circuit topology compatibility
2. Voltage - DC Reverse (Vr) (Max): Must equal or exceed 200 V
3. Current - Average Rectified (Io) (per Diode): Must equal or exceed 15 A to support the same load requirements
4. Package / Case: Must be TO-263-3, D2PAK (2 Leads + Tab), TO-263AB for PCB layout compatibility
5. Mounting Type: Must be surface mount
6. Speed Classification: Must be fast recovery ≤ 500ns, > 200mA (Io)
7. RoHS Status: Must be ROHS3 compliant

Substitute parts are grouped into two categories:

Category A - Full Current Rating (15 A): Parts meeting or exceeding the 15 A current specification

• DPG30C200PC-TRL (IXYS, 15 A, Active status)

Category B - Reduced Current Rating (10 A or 5 A): Parts with current ratings below 15 A, suitable only for applications with reduced current requirements

• FFB20UP20DN-F085 (onsemi, 10 A, Active status, AEC-Q101 qualified)
• SBR20A200CTB (Diodes Incorporated, 10 A, Active status)
• SBR20A200CTB-13 (Diodes Incorporated, 10 A, Active status)
• SBR10200CTB (Diodes Incorporated, 5 A, Active status)
• SBR10200CTB-13-G (Diodes Incorporated, 5 A, Active status)
• SFS1004G MNG (Taiwan Semiconductor Corporation, 10 A, Active status)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Full Current Compatibility)

DPG30C200PC-TRL from IXYS is the recommended primary substitute for STTH2002CG. This part maintains the 15 A current rating, 200 V reverse voltage specification, and TO-263-3 D2PAK package configuration. The device is in active production status, ensuring long-term availability. ROHS3 compliance and REACH unaffected status match the original part. The reverse recovery time of 35 ns is slightly higher than the original 27 ns but remains within fast recovery classification (≤ 500ns). Forward voltage at 1.26 V @ 15 A is marginally higher than the original specification but acceptable for most rectifier applications.

Secondary Substitutes (Reduced Current Rating)

For applications where current requirements do not exceed 10 A, the following active parts provide suitable alternatives:

• FFB20UP20DN-F085 (onsemi): Offers automotive-grade qualification (AEC-Q101) with 10 A rating. Suitable for automotive and industrial applications requiring enhanced reliability documentation.

• SBR20A200CTB and SBR20A200CTB-13 (Diodes Incorporated): Both provide 10 A rating with superior forward voltage characteristics (0.96 V @ 20 A) due to Super Barrier technology. Available in tube and tape & reel packaging options.

• SFS1004G MNG (Taiwan Semiconductor Corporation): Provides 10 A rating with active production status and ROHS3 compliance.

For applications limited to 5 A or less:

• SBR10200CTB and SBR10200CTB-13-G (Diodes Incorporated): Both offer 5 A rating with the lowest forward voltage (0.92 V @ 5 A) and fastest recovery time (20 ns) among all listed substitutes. Super Barrier technology provides enhanced performance characteristics.

All substitute parts maintain the required TO-263-3 D2PAK surface mount package, ROHS3 compliance, and 200 V reverse voltage rating. Selection should be based on actual circuit current requirements and packaging format availability (tube versus tape & reel).

Frequently Asked Questions (FAQ)

Q: Can DPG30C200PC-TRL directly replace STTH2002CG in all applications?

A: DPG30C200PC-TRL maintains the same 15 A current rating, 200 V reverse voltage, and TO-263-3 D2PAK package as STTH2002CG. The reverse recovery time of 35 ns is slightly longer than the original 27 ns but remains within fast recovery specification. Direct substitution is electrically and mechanically compatible for applications operating within these parameters.

Q: What is the difference between SBR20A200CTB and SBR20A200CTB-13?

A: Both parts are identical in electrical specifications (200 V, 10 A, Super Barrier technology). The primary difference is packaging format: SBR20A200CTB is supplied in tube packaging, while SBR20A200CTB-13 is supplied in tape & reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Why do some substitutes have lower current ratings than the original STTH2002CG?

A: The STTH2002CG is rated for 15 A per diode. Substitutes with 10 A or 5 A ratings are suitable only for applications where circuit current requirements do not exceed these limits. Using a lower-rated device in a higher-current application will result in thermal stress and potential device failure. Current rating must match or exceed the application requirement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the original STTH2002CG.

Q: What does "1 Pair Common Cathode" configuration mean?

A: This diode array contains two diodes sharing a common cathode connection. The configuration is essential for specific circuit topologies such as bridge rectifiers or synchronous switching applications. All substitute parts maintain this same configuration to preserve circuit functionality.

Q: Is FFB20UP20DN-F085 suitable for automotive applications?

A: FFB20UP20DN-F085 carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. This qualification provides enhanced reliability documentation and testing compliance required by automotive standards. Other substitutes do not carry this specific qualification.

Q: What is the significance of "Fast Recovery ≤ 500ns, > 200mA (Io)" specification?

A: This specification indicates the diode exhibits fast recovery characteristics with reverse recovery time not exceeding 500 nanoseconds at currents greater than 200 mA. All listed parts meet this classification, ensuring compatibility with high-frequency switching applications and reduced switching losses.

Q: Can I use SBR10200CTB (5 A) in place of STTH2002CG (15 A)?

A: SBR10200CTB can only be used if the application circuit current does not exceed 5 A. The part maintains the same 200 V reverse voltage and TO-263-3 D2PAK package, but the current rating is significantly reduced. Using this part in a 15 A application will cause device failure.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-quantity assembly. Tape & reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment. Electrical specifications are identical; selection depends on assembly process requirements.
