Engineering Selection Recommendations

Parametric Equivalent Selection:

STTH1002CGY-TR is a parametric equivalent to STTH1002CG-TR. Both parts are manufactured by STMicroelectronics with identical electrical specifications, diode configuration, voltage rating, current rating, and thermal characteristics. The only difference is packaging format: STTH1002CG-TR is supplied in Tape & Reel format, while STTH1002CGY-TR is supplied in Cut Tape format. Both parts are Active in product status and ROHS3 compliant. Selection between these two is determined by assembly equipment compatibility and supply chain requirements.

Similar Part Selection Based on Current Rating:

Parts with current ratings below 8 A (SBR10200CTB, SBR10200CTB-13-G at 5 A) are electrical downgrades and are suitable only for applications where the maximum required current does not exceed 5 A.

Parts with current ratings at or above 8 A (FFB20UP20DN-F085 at 10 A, SBR20A200CTB at 10 A, SBR20A200CTB-13 at 10 A, BYVB32-200-E3/81 at 18 A) are electrical upgrades and are suitable for applications requiring 8 A or higher current capacity.

Technology Considerations:

Standard technology parts (STTH series) and Super Barrier technology parts (SBR series) both meet the 200 V reverse voltage and common cathode configuration requirements. Super Barrier technology typically offers lower forward voltage drop, which may reduce thermal dissipation in high-current applications.

Product Status Considerations:

BYVB32-200-E3/81 is designated as Last Time Buy. This status indicates limited future availability. Selection of this part should be avoided for new designs unless supply chain constraints mandate its use.

All other substitute parts listed are Active in product status, indicating ongoing manufacturing and availability.

Compliance and Certification:

All listed parts are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

FFB20UP20DN-F085 carries AEC-Q101 automotive qualification, suitable for automotive applications requiring this certification.

STTH1002CGY-TR carries AEC-Q101 automotive qualification, suitable for automotive applications requiring this certification.

Frequently Asked Questions (FAQ)

Q: Can STTH1002CGY-TR be used as a direct replacement for STTH1002CG-TR?

A: Yes. STTH1002CGY-TR is a parametric equivalent with identical electrical specifications, diode configuration, voltage rating, current rating, and package dimensions. The only difference is packaging format (Cut Tape vs. Tape & Reel). Compatibility depends on assembly equipment capability to handle the different packaging format.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on individual tape segments, typically used for lower-volume assembly or manual handling. Both formats contain the same component in the same package.

Q: Can SBR10200CTB (5 A rating) replace STTH1002CG-TR (8 A rating)?

A: SBR10200CTB can replace STTH1002CG-TR only if the application's maximum required current does not exceed 5 A. If the application requires 8 A or higher current capacity, SBR10200CTB is not suitable. The 200 V reverse voltage rating, common cathode configuration, and TO-263-3 D2PAK package are compatible.

Q: Can SBR20A200CTB (10 A rating) replace STTH1002CG-TR (8 A rating)?

A: Yes. SBR20A200CTB is rated for 10 A, which exceeds the 8 A requirement of STTH1002CG-TR. The 200 V reverse voltage rating, common cathode configuration, and TO-263-3 D2PAK package are identical. The Super Barrier technology offers lower forward voltage drop (960 mV vs. 1.1 V), which may reduce thermal dissipation. Thermal design must accommodate the higher current capability if the application does not utilize the full 10 A rating.

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

A: Reverse recovery time is the time required for the diode to switch from forward conduction to reverse blocking. STTH1002CG-TR has a trr of 25 ns. Substitute parts with shorter trr values (such as SBR10200CTB at 20 ns) switch faster and may reduce switching losses in high-frequency applications. Substitute parts with longer trr values (such as FFB20UP20DN-F085 at 40 ns) switch more slowly and may increase switching losses. Selection depends on the application's switching frequency and thermal budget.

Q: What does "Last Time Buy" product status mean?

A: Last Time Buy indicates that the manufacturer has announced the end of production for that part. BYVB32-200-E3/81 is designated Last Time Buy, meaning limited quantities remain available and no future production is planned. This part should not be selected for new designs unless supply chain constraints mandate its use. Existing designs using this part should transition to an Active alternative.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference are ROHS3 compliant, indicating compliance with the Restriction of Hazardous Substances Directive. All parts have Moisture Sensitivity Level 1 (Unlimited), requiring no special moisture handling during storage or assembly.

Q: What is the difference between Standard and Super Barrier technology?

A: Standard technology (STTH series) and Super Barrier technology (SBR series) are different semiconductor junction designs. Super Barrier technology typically offers lower forward voltage drop, reducing power dissipation and heat generation. Both technologies meet the 200 V reverse voltage and common cathode configuration requirements. Selection depends on thermal design requirements and forward voltage drop specifications for the target application.

Q: Can BYVB32-200-E3/81 (18 A rating) replace STTH1002CG-TR (8 A rating)?

A: Yes, from an electrical compatibility standpoint. BYVB32-200-E3/81 is rated for 18 A, exceeding the 8 A requirement. The 200 V reverse voltage rating, common cathode configuration, and TO-263-3 D2PAK package are compatible. However, BYVB32-200-E3/81 is designated Last Time Buy, indicating limited future availability. This part should not be selected for new designs.

Q: What packaging formats are available for equivalent parts?

A: Substitute parts are available in the following packaging formats: Tape & Reel (TR), Cut Tape (CT), and Tube. Tape & Reel is standard for high-volume automated assembly. Cut Tape is used for lower-volume assembly or manual handling. Tube packaging is used for component storage and manual assembly. All formats contain the same component in the same TO-263-3 D2PAK package.
