Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMTH45M5SFVW-13 is determined by electrical and mechanical parameter equivalence. The primary substitute identified is the DMTH45M5SFVWQ-13, which maintains identical electrical specifications across all critical parameters: Vdss, continuous drain current (both Ta and Tc ratings), Rds On, gate threshold voltage, gate charge, input capacitance, and power dissipation ratings. Both parts utilize the same 8-PowerVDFN package with surface mount, wettable flank mounting configuration.

The key differentiator between the main part and its substitute is the addition of automotive-grade qualification (AEC-Q101) in the DMTH45M5SFVWQ-13. This qualification indicates the substitute part meets automotive industry reliability and quality standards. Both parts maintain identical RoHS3 compliance, moisture sensitivity level (MSL 1), and REACH unaffected status. The substitute part is available with higher inventory (1090 units versus 775 units).

Substitution is valid when electrical performance equivalence and package compatibility are the primary selection criteria. The automotive qualification of the substitute part does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DMTH45M5SFVW-13 and DMTH45M5SFVWQ-13 are active production parts from Diodes Incorporated with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on application requirements and supply chain considerations.

The DMTH45M5SFVW-13 is suitable for general industrial and commercial power switching applications where automotive qualification is not required. This part offers standard reliability characteristics with 775 units currently in stock.

The DMTH45M5SFVWQ-13 is the preferred selection for automotive applications and systems requiring AEC-Q101 qualification. This substitute part maintains identical electrical performance while meeting automotive industry quality standards. The DMTH45M5SFVWQ-13 is available with higher inventory (1090 units), providing improved supply chain availability.

Both parts are electrically and mechanically interchangeable. The choice between them depends on whether automotive-grade qualification is a system requirement. For applications without automotive specifications, either part delivers equivalent performance. For automotive or safety-critical applications, the AEC-Q101 qualified substitute is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the DMTH45M5SFVW-13 and DMTH45M5SFVWQ-13 electrically identical?

A: Yes. Both parts share identical electrical specifications including Vdss (40V), continuous drain current (18A at Ta, 71A at Tc), Rds On (5.5 mOhm @ 25A, 10V), gate threshold voltage (3.5V @ 250µA), gate charge (13.2 nC @ 10V), and input capacitance (1083 pF @ 20V).
