Substitute Part Grouping Explanation

Substitution eligibility for the STTH2002CG-TR is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Diode Configuration: 1 Pair Common Cathode (electrical pinout compatibility)
Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (mechanical and thermal interface)
Voltage - DC Reverse (Vr) (Max): 200 V (minimum voltage rating requirement)
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) (switching performance class)
Mounting Type: Surface Mount (assembly process compatibility)
RoHS Status: ROHS3 Compliant (regulatory requirement)

Current Rating Consideration: The STTH2002CG-TR specifies 15 A average rectified current per diode. Substitute parts with equal or greater current ratings maintain full functional equivalence. Substitute parts with lower current ratings (10 A or 5 A) operate within reduced current capacity and are classified as derating substitutes.

Electrical Performance Parameters: Forward voltage (Vf), reverse recovery time (trr), and reverse leakage current are secondary selection criteria that vary by manufacturer and technology type (Standard vs. Super Barrier). These parameters influence efficiency and thermal performance but do not prevent substitution when primary criteria are met.

Engineering Selection Recommendations

Full Equivalence Substitutes (Equal or Greater Current Rating):

FFB20UP20DN-F085 (onsemi) and SBR20A200CTB / SBR20A200CTB-13 (Diodes Incorporated) operate at 10 A average rectified current, which is lower than the STTH2002CG-TR specification of 15 A. These parts maintain identical voltage ratings, package configuration, and fast recovery speed classification. All three substitute options carry Active product status and ROHS3 compliance. The onsemi FFB20UP20DN-F085 includes AEC-Q101 automotive qualification. The Diodes Incorporated SBR20A200CTB and SBR20A200CTB-13 employ Super Barrier technology, resulting in lower forward voltage characteristics compared to the standard technology of the main part.

Derating Substitutes (Reduced Current Rating):

SBR10200CTB and SBR10200CTB-13-G (Diodes Incorporated) operate at 5 A average rectified current, representing a 67% reduction from the STTH2002CG-TR 15 A rating. These parts are suitable only for applications where the actual operating current does not exceed 5 A. Both maintain identical voltage ratings, package configuration, and fast recovery speed classification. Both carry Active product status and ROHS3 compliance. Super Barrier technology provides superior forward voltage performance at reduced current levels.

FFB20UP20DN-F085 provides 6,396 pieces in Tape & Reel format. SBR20A200CTB-13 provides 3,000 pieces in Tape & Reel format. SBR20A200CTB provides 7,625 pieces in Tube format. SBR10200CTB-13-G provides 1,528 pieces in Tape & Reel format. SBR10200CTB provides 1,660 pieces in Tube format.

Frequently Asked Questions (FAQ)

Q: Can FFB20UP20DN-F085 directly replace STTH2002CG-TR in all applications?

A: FFB20UP20DN-F085 is electrically compatible with STTH2002CG-TR in applications where the actual operating current does not exceed 10 A. The part maintains identical 200 V reverse voltage rating, 1 Pair Common Cathode configuration, and TO-263-3 D2PAK package. The 10 A current rating is lower than the STTH2002CG-TR 15 A specification. Thermal performance and current capacity must be evaluated for the specific application.

Q: What is the difference between Standard and Super Barrier diode technology in these substitutes?

A: Standard technology (STTH2002CG-TR, FFB20UP20DN-F085) and Super Barrier technology (SBR series) are both fast recovery rectifier classifications. Super Barrier diodes exhibit lower forward voltage drop, which reduces power dissipation and improves efficiency. The choice between technologies depends on application requirements for thermal management and power efficiency. Both technologies meet the fast recovery speed classification of ≤ 500ns.

Q: Are SBR10200CTB and SBR10200CTB-13-G suitable substitutes for STTH2002CG-TR?

A: SBR10200CTB and SBR10200CTB-13-G are suitable only for applications where the actual operating current does not exceed 5 A. These parts provide 67% lower current capacity than the STTH2002CG-TR 15 A rating. All other electrical parameters (200 V reverse voltage, 1 Pair Common Cathode configuration, fast recovery speed) and package specifications (TO-263-3 D2PAK) are compatible. Current derating must be confirmed before selection.

Q: What is the difference between Tape & Reel (TR) and Tube packaging?

A: Tape & Reel (TR) packaging is suitable for automated assembly processes with reel-fed component placement equipment. Tube packaging is suitable for manual assembly or lower-volume production processes. Both packaging formats contain identical electronic components. Selection depends on manufacturing process requirements and assembly equipment compatibility.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed (FFB20UP20DN-F085, SBR10200CTB, SBR10200CTB-13-G, SBR20A200CTB, SBR20A200CTB-13) carry ROHS3 Compliant status, matching the STTH2002CG-TR compliance level. All parts maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of AEC-Q101 qualification on FFB20UP20DN-F085?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. FFB20UP20DN-F085 carries this qualification, indicating suitability for automotive applications requiring enhanced reliability and quality assurance. The STTH2002CG-TR does not list AEC-Q101 qualification. Selection of AEC-Q101 qualified parts is necessary only when automotive qualification is a design requirement.

Q: How do reverse recovery time (trr) differences affect substitution decisions?

A: Reverse recovery time (trr) is a secondary electrical parameter that influences switching performance and electromagnetic interference characteristics. The STTH2002CG-TR specifies 27 ns trr. Substitute parts range from 20 ns (SBR10200CTB series) to 40 ns (FFB20UP20DN-F085). All parts meet the fast recovery speed classification. Trr differences are relevant only for high-frequency switching applications where EMI performance is critical.

Q: Can substitute parts with lower reverse leakage current improve application performance?

A: Reverse leakage current affects standby power consumption and thermal performance. The STTH2002CG-TR specifies 10 µA @ 200 V. SBR10200CTB series specifies 5 µA @ 200 V (lower leakage), while SBR20A200CTB series specifies 100 µA @ 200 V (higher leakage). Lower leakage current reduces standby power dissipation. Selection based on leakage current is application-specific and depends on standby power requirements.
