Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH1002CG is determined by the following critical parameters:

1. Diode Configuration: Must be 1 pair common cathode topology
2. Voltage Rating: Minimum 200 V DC reverse voltage (Vr)
3. Current Rating: Minimum 8 A average rectified current per diode (Io)
4. Package: TO-263-3 (D2PAK) surface mount form factor
5. Speed Classification: Fast recovery characteristics (≤500 ns)
6. Mounting Type: Surface mount compatibility

Substitute parts are grouped into two categories:

Direct Equivalent (Same Specifications)

• STTH1002CG-TR: Identical electrical specifications, active product status, tape & reel packaging

Functional Equivalents (Enhanced or Comparable Specifications)

• Parts meeting or exceeding the minimum voltage, current, and package requirements while maintaining the same diode configuration and fast recovery speed classification
• Includes parts with higher current ratings (10 A), alternative technologies (Super Barrier), or automotive qualifications

Engineering Selection Recommendations

Primary Recommendation: STTH1002CG-TR

STTH1002CG-TR is the direct equivalent substitute for STTH1002CG. This part maintains identical electrical specifications (200 V, 8 A, 25 ns recovery time) and diode configuration while offering active product status. The only difference is packaging format (tape & reel versus tube). This part is suitable for direct replacement in production environments requiring continuous supply.

Secondary Recommendations for Enhanced Performance:

VS-MURB1620CTRHM3 (Vishay General Semiconductor - Diodes Division)

• Matches the 8 A current rating of the original STTH1002CG
• Offers improved forward voltage (0.975 V vs. 1.1 V), reducing power dissipation
• Faster recovery time (20 ns vs. 25 ns)
• Automotive grade with AEC-Q101 qualification
• Active product status with established supply chain

SBR20A200CTB-13 (Diodes Incorporated)

• Exceeds current rating (10 A vs. 8 A), providing design margin
• Super Barrier technology delivers lower forward voltage (0.96 V @ 20 A)
• Faster recovery time (30 ns)
• Active product status
• Tape & reel packaging for automated assembly

For Current-Limited Applications:

SBR10200CTB-13-G (Diodes Incorporated)

• Suitable where 5 A per diode is sufficient
• Lowest forward voltage (0.92 V @ 5 A) among substitutes
• Fastest recovery time (20 ns)
• Super Barrier technology
• Active product status

For Higher Current Requirements:

FFB20UP20DN-F085 (onsemi)

• Highest current rating (10 A per diode)
• Automotive grade with AEC-Q101 qualification
• Active product status
• Tape & reel packaging

All recommended substitutes maintain the TO-263-3 (D2PAK) package footprint, 200 V voltage rating, fast recovery speed classification, and RoHS3 compliance required for direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can STTH1002CG-TR be used as a direct replacement for STTH1002CG?

A: Yes. STTH1002CG-TR is electrically identical to STTH1002CG with matching voltage (200 V), current (8 A per diode), and recovery time (25 ns) specifications. The only difference is packaging format: STTH1002CG-TR is supplied in tape & reel format while STTH1002CG is supplied in tube format. Both use the same TO-263-3 (D2PAK) package footprint.

Q: What is the difference between the STTH1002CG and SBR20A200CTB-13?

A: Both parts share the same 200 V voltage rating and TO-263-3 package. Key differences are: (1) Current rating: SBR20A200CTB-13 is rated for 10 A per diode versus 8 A for STTH1002CG; (2) Technology: SBR20A200CTB-13 uses Super Barrier technology resulting in lower forward voltage (0.96 V vs. 1.1 V); (3) Recovery time: SBR20A200CTB-13 has 30 ns recovery versus 25 ns for STTH1002CG. The higher current rating of SBR20A200CTB-13 provides design margin for applications approaching the 8 A limit.

Q: Is the VS-MURB1620CTRHM3 suitable for automotive applications?

A: Yes. VS-MURB1620CTRHM3 carries automotive grade qualification with AEC-Q101 certification. It matches the 8 A current rating of STTH1002CG while offering improved performance characteristics (lower forward voltage and faster recovery time). This part is suitable for automotive and industrial applications requiring qualified components.

Q: Can I use FFB20UP20DN-F085 in place of STTH1002CG?

A: Yes, with design considerations. FFB20UP20DN-F085 meets the 200 V voltage requirement and exceeds the 8 A current requirement (rated 10 A per diode). The package is identical (TO-263-3). However, the recovery time is longer (40 ns vs. 25 ns). This part is suitable for applications where the higher current rating provides beneficial design margin and the longer recovery time does not impact circuit performance. FFB20UP20DN-F085 carries automotive grade qualification with AEC-Q101 certification.

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

A: This diode array contains two independent 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 listed maintain this same 1 pair common cathode configuration, ensuring functional compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (STTH1002CG-TR, FFB20UP20DN-F085, SBR10200CTB-13-G, SBR20A200CTB, SBR20A200CTB-13, and VS-MURB1620CTRHM3) are RoHS3 compliant with MSL rating of 1 (Unlimited), matching the environmental compliance profile of the original STTH1002CG.

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

A: Both parts are electrically identical with 200 V rating, 10 A current per diode, and identical recovery characteristics. The only difference is packaging format: SBR20A200CTB is supplied in tube format while SBR20A200CTB-13 is supplied in tape & reel format. Both use the same TO-263-3 (D2PAK) package footprint.

Q: Which substitute offers the lowest forward voltage drop?

A: SBR10200CTB-13-G offers the lowest forward voltage at 0.92 V @ 5 A, followed by SBR20A200CTB and SBR20A200CTB-13 at 0.96 V @ 20 A. Lower forward voltage reduces power dissipation in rectification applications. However, SBR10200CTB-13-G is rated for 5 A per diode, which is below the original 8 A specification.

Q: Can I mix different substitute parts in the same design?

A: All substitute parts maintain the same TO-263-3 (D2PAK) package footprint and 200 V voltage rating, allowing board-level compatibility. However, mixing parts with different current ratings or recovery times in the same circuit may result in unequal current distribution or timing mismatches. Consistent part selection across a design is recommended for predictable circuit behavior.
