Engineering Selection Recommendations

Direct Equivalent (10 A Rating): STTH10R04G-TR is the direct current-rated equivalent to GPAS1004 MNG. Both components share identical voltage and current specifications with matching D2PAK packaging. STTH10R04G-TR exhibits faster recovery characteristics (40 ns versus standard recovery) and operates across an extended temperature range (-40 to 175°C versus -55 to 150°C). This part is suitable for applications requiring identical electrical performance with enhanced thermal operating margin.

Higher Current Capacity (30 A Rating): STTH30R04G and STTH30R04G-TR provide 30 A current capacity, exceeding the 10 A requirement of GPAS1004 MNG. These parts maintain 400 V reverse voltage rating and D2PAK packaging. The difference between STTH30R04G (Tube packaging) and STTH30R04G-TR (Cut Tape & Digi-Reel packaging) reflects supply format only; electrical specifications are identical. These parts are suitable for applications where increased current handling capacity is required within the same voltage and package constraints.

Lower Current Capacity (8 A Rating): STTH8R04G-TR provides 8 A current capacity, below the 10 A specification of GPAS1004 MNG. This part is suitable only for applications with maximum current requirements not exceeding 8 A. All other electrical and package specifications align with the main part.

Compliance and Regulatory Status: All substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) rating, ensuring compatibility with existing supply chain and manufacturing requirements. All parts are classified as Active product status.

Frequently Asked Questions (FAQ)

Q: Can STTH10R04G-TR be used as a direct replacement for GPAS1004 MNG?

A: Yes. STTH10R04G-TR matches the 400 V reverse voltage, 10 A current rating, and D2PAK package of GPAS1004 MNG. Both components are RoHS3 compliant with MSL 1 rating. The primary difference is faster recovery time (40 ns versus standard recovery) and extended maximum junction temperature (175°C versus 150°C), which are compatible with applications designed for GPAS1004 MNG.

Q: What is the difference between STTH30R04G and STTH30R04G-TR?

A: STTH30R04G and STTH30R04G-TR are electrically identical 30 A rectifier diodes with 400 V rating in D2PAK packaging. The difference is packaging format: STTH30R04G is supplied in Tube packaging, while STTH30R04G-TR is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility and supply chain requirements.

Q: Can STTH30R04G be used in place of GPAS1004 MNG?

A: Yes, with application review. STTH30R04G maintains the 400 V reverse voltage rating and D2PAK package. The 30 A current rating exceeds the 10 A requirement, providing additional current capacity margin. This substitution is suitable for applications where higher current handling is beneficial or required.

Q: Is STTH8R04G-TR suitable as a substitute for GPAS1004 MNG?

A: STTH8R04G-TR is suitable only for applications where maximum current does not exceed 8 A. The 8 A rating is below the 10 A specification of GPAS1004 MNG. All other electrical parameters (400 V reverse voltage, D2PAK package, RoHS3 compliance) are compatible.

Q: Do all substitute parts use the same D2PAK package?

A: Yes. All substitute parts (STTH10R04G-TR, STTH30R04G, STTH30R04G-TR, STTH8R04G-TR) use TO-263-3 D2PAK (2 Leads + Tab) packaging, enabling direct board-level replacement without layout modification.

Q: What is the impact of forward voltage differences between GPAS1004 MNG and substitute parts?

A: GPAS1004 MNG specifies 1.1 V forward voltage at 10 A. STTH10R04G-TR specifies 1.7 V at 10 A. Higher forward voltage results in increased power dissipation. Applications with thermal constraints or efficiency requirements should account for this difference. STTH30R04G and STTH30R04G-TR specify 1.45 V at 30 A, representing intermediate forward voltage characteristics.

Q: Are all substitute parts available in the same quantities?

A: Inventory levels vary. STTH8R04G-TR has the highest inventory (20,400 pcs), followed by STTH10R04G-TR (2,870 pcs), STTH30R04G-TR (2,252 pcs), and STTH30R04G (1,256 pcs). GPAS1004 MNG has 930 pcs in stock. Availability should be confirmed for production requirements.
