Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH1602CG is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V (exact match required)
• Current - Average Rectified (Io) (per Diode): 10 A (exact match required for full-current applications)
• Diode Configuration: 1 Pair Common Cathode (exact match required)
• Package / Case: TO-263-3, D2PAK (exact match required)
• Speed Classification: Fast Recovery ≤500ns, >200mA (Io) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: Acceptable within design margin
• Reverse Recovery Time (trr): Acceptable within design margin
• Current - Reverse Leakage @ Vr: Acceptable within design margin
• Operating Temperature - Junction: Acceptable if equal to or exceeding 175°C maximum

Substitute parts are grouped into two categories: full electrical equivalents (matching 10 A current rating) and reduced-current alternatives (5 A rating) suitable for applications with lower current requirements.

Parameter Comparison

Engineering Selection Recommendations

Full-Current Equivalents (10 A Rating):

SBR20A200CTB-13 (Diodes Incorporated) and SBR20A200CTB (Diodes Incorporated) are direct electrical equivalents with active product status. Both maintain the 200 V reverse voltage, 10 A current rating, and TO-263-3 D2PAK package. The SBR20A200CTB-13 is supplied in Tape & Reel packaging, while SBR20A200CTB is supplied in Tube packaging. Both employ Super Barrier technology with 30 ns reverse recovery time and extended operating temperature range (-65°C to 175°C). These parts are suitable for direct replacement in applications requiring full 10 A current capacity.

FFB20UP20DN-F085 (onsemi) is an active equivalent with identical 200 V, 10 A specifications and TO-263-3 D2PAK package. This part includes AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging. The 40 ns reverse recovery time is within acceptable design margin for fast recovery applications.

Reduced-Current Alternative (8 A Rating):

VS-MURB1620CTRHM3 (Vishay General Semiconductor) is an active substitute with 200 V reverse voltage and 8 A current rating in TO-263-3 D2PAK package. This part includes AEC-Q101 automotive qualification and FRED Pt® series designation. The 8 A rating is suitable for applications with reduced current requirements or where thermal management permits lower current operation.

Reduced-Current Alternative (5 A Rating):

SBR10200CTB-13-G (Diodes Incorporated) is an active substitute with 200 V reverse voltage and 5 A current rating in TO-263-3 D2PAK package. This part is suitable only for applications with maximum current requirements of 5 A or less.

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity, and REACH Unaffected status, ensuring regulatory compatibility with the original STTH1602CG.

Frequently Asked Questions (FAQ)

Q: Can SBR20A200CTB-13 or SBR20A200CTB directly replace STTH1602CG in all applications?

A: Yes, both SBR20A200CTB-13 and SBR20A200CTB maintain identical electrical specifications (200 V, 10 A) and package configuration (TO-263-3 D2PAK). Both are active products with extended operating temperature range and are suitable for direct replacement. The primary difference is packaging format: SBR20A200CTB-13 is supplied in Tape & Reel, while SBR20A200CTB is supplied in Tube.

Q: What is the difference between FFB20UP20DN-F085 and the SBR20A200CTB series?

A: FFB20UP20DN-F085 (onsemi) and SBR20A200CTB series (Diodes Incorporated) both provide 200 V, 10 A ratings in TO-263-3 D2PAK packages. FFB20UP20DN-F085 uses standard diode technology with 40 ns reverse recovery time, while SBR20A200CTB series uses Super Barrier technology with 30 ns reverse recovery time. Both are active products with automotive qualification (AEC-Q101).

Q: Can VS-MURB1620CTRHM3 be used as a substitute for STTH1602CG?

A: VS-MURB1620CTRHM3 is suitable as a substitute only in applications where the 8 A current rating is acceptable. The part maintains 200 V reverse voltage and TO-263-3 D2PAK package compatibility. Applications requiring the full 10 A current capacity of STTH1602CG must use FFB20UP20DN-F085, SBR20A200CTB, or SBR20A200CTB-13.

Q: Is SBR10200CTB-13-G a suitable replacement for STTH1602CG?

A: SBR10200CTB-13-G is suitable only for applications with maximum current requirements of 5 A or less. The part maintains 200 V reverse voltage and TO-263-3 D2PAK package compatibility but is rated for half the current capacity of STTH1602CG. Applications requiring 10 A operation must use full-current equivalents.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed (FFB20UP20DN-F085, SBR10200CTB-13-G, SBR20A200CTB, SBR20A200CTB-13, and VS-MURB1620CTRHM3) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity and REACH Unaffected status, matching the regulatory compliance of STTH1602CG.

Q: What is the significance of the reverse recovery time (trr) differences?

A: Reverse recovery time indicates the speed at which the diode transitions from conducting to blocking state. STTH1602CG specifies 26 ns. Substitute parts range from 20 ns (SBR10200CTB-13-G, VS-MURB1620CTRHM3) to 40 ns (FFB20UP20DN-F085). All values remain within the fast recovery classification (≤500 ns) and are acceptable for applications designed for STTH1602CG.

Q: Does packaging format (Tape & Reel vs. Tube) affect electrical performance?

A: No, packaging format does not affect electrical performance. Tape & Reel and Tube packaging are logistics and assembly considerations only. SBR20A200CTB-13 (Tape & Reel) and SBR20A200CTB (Tube) are electrically identical and interchangeable.

Q: Are automotive-qualified parts (AEC-Q101) required for all applications?

A: Automotive qualification (AEC-Q101) is required only for applications in automotive environments. FFB20UP20DN-F085 and VS-MURB1620CTRHM3 include AEC-Q101 qualification. SBR20A200CTB and SBR20A200CTB-13 do not specify AEC-Q101 qualification but are suitable for non-automotive applications.
