Engineering Selection Recommendations

PMPB20XNEAZ (Parametric Equivalent): The PMPB20XNEAZ is a direct parametric equivalent to the PMPB20XNEAX. Both devices are manufactured by Nexperia USA Inc. and share identical electrical specifications, package configuration (DFN2020MD-6), and automotive qualifications (AEC-Q101). Selection between these two part numbers is based on inventory availability and supply chain considerations. Both parts maintain equivalent performance in all specified operating conditions.

DMN2022UFDF-13 (Similar Manufacturer Alternative): The DMN2022UFDF-13 manufactured by Diodes Incorporated meets the core voltage (20V) and current (7.9A) requirements and is housed in a compatible 6-UDFN Exposed Pad package. This device exhibits higher continuous drain current capability (7.9A versus 7.5A) and improved power dissipation (660mW Ta versus 460mW Ta). Secondary parameter variations include lower gate threshold voltage (1V versus 1.25V), slightly higher gate charge (18nC versus 15nC), and lower maximum gate voltage rating (±8V versus ±12V). This part is suitable for applications where the primary design constraints are voltage rating, current capacity, and package compatibility. Automotive grade and AEC-Q101 qualification status are not specified for this device.

Selection Criteria:

For automotive applications requiring AEC-Q101 qualification: PMPB20XNEAX or PMPB20XNEAZ
For general industrial applications with compatible package requirements: DMN2022UFDF-13
For inventory optimization within the same manufacturer: PMPB20XNEAZ as alternative to PMPB20XNEAX

Frequently Asked Questions (FAQ)
