FDMA3028N

FET, MOSFET Arrays Overview

The FDMA3028N is a dual N-channel enhancement-mode MOSFET from onsemi's PowerTrench series. It features a MicroFET-6 surface-mount package with three pins per channel configuration within the six-pin footprint. Key electrical parameters include a drain-source voltage (Vds) of 30 V and a continuous drain current (Id) of 3.8 A. The device exhibits a maximum on-resistance (Rds(on)) of 123 mΩ at standard test conditions. Gate-source voltage limits are specified at ±12 V, with a typical gate charge (Qg) of 5.2 nC. The component operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 1.5 W.

FET, MOSFET Arrays Procurement Notes

Verify availability status carefully as this component is listed as discontinued or having restricted supply through major distributors like Mouser. Confirm end-of-life status directly with onsemi before finalizing design-in decisions. Check for alternative sourcing channels if immediate procurement is required, noting that standard lead times may not apply due to limited stock conditions.

FET, MOSFET Arrays Selection Notes

Select this part only if the 30 V drain-source voltage and 3.8 A current ratings sufficiently cover the application requirements. Consider the 123 mΩ on-resistance impact on thermal performance given the 1.5 W power dissipation limit in the MicroFET-6 package. Evaluate whether the dual-channel architecture provides necessary functionality compared to single-channel alternatives, keeping in mind its discontinued status may affect long-term production viability.

FET, MOSFET Arrays Part Context

The FDMA3028N belongs to onsemi's PowerTrench family, which focuses on low-gate-charge MOSFETs for efficient power conversion. This specific model represents an older generation dual-channel solution designed for compact form factors. It serves as a legacy component for existing designs requiring integrated dual N-channel switching in low-voltage environments, preceding newer high-density packaging technologies.

FET, MOSFET Arrays Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, engineers must identify equivalent dual N-channel MOSFETs with matching 30 V/3.8 A ratings and compatible MicroFET-6 pinouts through independent cross-reference tools.
