Parameter Comparison

Engineering Selection Recommendations

DMTH46M7SFVW-7 is a direct parametric equivalent to the DMTH46M7SFVW-13, maintaining identical electrical specifications and mechanical construction. This part is currently in active production status and available in Tape & Reel packaging format. Selection of this substitute is appropriate for applications requiring standard industrial-grade components with continuous supply availability.

DMTH46M7SFVWQ-7 is a parametric equivalent with additional automotive-grade qualification under AEC-Q101 standard. This variant is suitable for applications requiring automotive-level reliability and traceability. The part maintains all electrical and mechanical specifications identical to the primary part while offering enhanced qualification documentation. Selection of this substitute is appropriate for automotive applications or systems requiring AEC-Q101 compliance.

Both substitute parts are manufactured by Diodes Incorporated and are ROHS3 compliant with MSL rating of 1 (Unlimited). The primary differentiation between substitutes is the automotive qualification status of DMTH46M7SFVWQ-7 and the packaging format (Tape & Reel for both substitutes versus cut tape for the discontinued primary part).

Frequently Asked Questions (FAQ)

Q: Can DMTH46M7SFVW-7 be used as a direct replacement for DMTH46M7SFVW-13?

A: Yes. Both parts are parametrically identical across all electrical specifications (Vdss, drain current, Rds On, gate charge, input capacitance, and operating temperature range) and mechanical construction (8-PowerVDFN package, surface mount with wettable flank). The primary difference is packaging format: DMTH46M7SFVW-7 is supplied in Tape & Reel format while DMTH46M7SFVW-13 was supplied in cut tape. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between DMTH46M7SFVW-7 and DMTH46M7SFVWQ-7?

A: Both parts are parametrically identical in electrical and mechanical specifications. The DMTH46M7SFVWQ-7 variant includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring enhanced reliability documentation and traceability. The standard DMTH46M7SFVW-7 is appropriate for industrial applications without automotive requirements.

Q: Are the substitute parts pin-compatible with the original DMTH46M7SFVW-13?

A: Yes. All three parts use the identical 8-PowerVDFN package (PowerDI3333-8 SWP Type UX) with surface mount, wettable flank construction. Pin configuration, footprint, and soldering requirements are identical.

Q: Can I use DMTH46M7SFVWQ-7 in non-automotive applications?

A: Yes. The DMTH46M7SFVWQ-7 is a superset of the standard DMTH46M7SFVW-7, offering additional AEC-Q101 qualification. It maintains all electrical and mechanical specifications and can be used in any application where the standard variant is suitable. The automotive qualification does not restrict use in industrial applications.

Q: What is the significance of the "-7" and "-13" suffixes in the part numbers?

A: The suffix indicates the packaging format and tape configuration. DMTH46M7SFVW-13 was supplied in cut tape format and is now discontinued. DMTH46M7SFVW-7 and DMTH46M7SFVWQ-7 are supplied in Tape & Reel (TR) format for automated assembly processes. Electrical and mechanical specifications are identical regardless of suffix.

Q: Are there any thermal performance differences between the substitute parts?

A: No. All three parts have identical power dissipation ratings: 3.2 W (Ta) and 54.5 W (Tc), with operating temperature range of -55°C to 175°C. Thermal performance is determined by the die and package construction, which are identical across all variants.

Q: What is the MSL rating and why is it important?

A: All three parts carry MSL (Moisture Sensitivity Level) rating of 1 (Unlimited), indicating unlimited shelf life without moisture control requirements. This simplifies inventory management and reduces handling constraints during storage and assembly.
