Substitute Part Grouping Explanation

Substitute parts for the BAS20DWQ-13 are identified based on strict equivalence across the following critical parameters:

Diode configuration (2 Independent circuits)
Maximum reverse voltage rating (150 V)
Average rectified current per diode (200 mA)
Forward voltage drop (1.25 V @ 200 mA)
Reverse recovery time (50 ns)
Reverse leakage current (100 nA @ 150 V)
Operating temperature range (-65°C ~ 150°C)
Package type (6-TSSOP, SC-88, SOT-363)
Surface mount compatibility
Automotive grade qualification (AEC-Q101)
RoHS3 compliance

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in packaging designation, supplier device package labeling, or inventory levels do not affect substitution eligibility when all electrical and mechanical parameters remain identical.

Engineering Selection Recommendations

The BAS20DW-7 is a direct parametric equivalent to the BAS20DWQ-13. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these two part numbers is based on availability and supply chain requirements rather than technical performance differences.

Both parts maintain active production status and comply with ROHS3 and REACH regulations. The BAS20DWQ-13 currently has higher inventory availability (45,100 units) compared to the BAS20DW-7 (5,300 units). For applications requiring automotive-grade qualification, both parts satisfy AEC-Q101 requirements. The choice between these substitutes should be determined by procurement lead times, inventory allocation, and supplier logistics.

Frequently Asked Questions (FAQ)

Q: Can BAS20DW-7 be used as a direct replacement for BAS20DWQ-13 in automotive applications?

A: Yes. Both parts are AEC-Q101 qualified and share identical electrical parameters, reverse voltage ratings, current ratings, and operating temperature ranges. The SOT-363 package compatibility ensures mechanical interchangeability on PCB layouts designed for either part number.

Q: Are there differences in the package designation between BAS20DWQ-13 and BAS20DW-7?

A: Both parts use the 6-TSSOP, SC-88, SOT-363 package. The supplier device package designation is SOT-363 for both. Package footprints and pin configurations are identical.

Q: What is the significance of the different suffixes (-DWQ-13 versus -DW-7) in these part numbers?

A: The suffix variations indicate different manufacturing date codes or tape reel configurations from Diodes Incorporated. These designations do not reflect changes to electrical specifications or performance characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both BAS20DWQ-13 and BAS20DW-7 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts support the same operating temperature range of -65°C to 150°C junction temperature, enabling use in applications requiring extended thermal performance within this range.

Q: What is the reverse recovery time specification for both parts?

A: Both parts specify a reverse recovery time (trr) of 50 ns, indicating identical switching characteristics for small-signal rectification applications.
