Overview
The NTMFD1D6N03P8 is a dual N-Channel PowerTrench MOSFET in a PQFN8 Power Clip package. It integrates a control MOSFET (Q1) and a synchronous SyncFET (Q2) with an internally connected switch node for synchronous buck converters. Q1 features a maximum rDS(on) of 5.0 mΩ at VGS = 10 V, ID = 17 A. Q2 offers a maximum rDS(on) of 1.6 mΩ at VGS = 10 V, ID = 32 A. Both devices have a 30 V drain-source breakdown voltage. The low inductance packaging reduces switching losses and circuit inductance.
Feature Summary
- Internal connection between the switch nodes of the control and synchronous MOSFETs simplifies layout and routing for synchronous buck applications.
- Asymmetric design provides optimized power efficiency by pairing a dedicated control FET with a high-current synchronous FET.
- Low inductance Power Clip packaging minimizes rise and fall times to reduce switching losses and suppress switch node ringing.
Applications
- Synchronous Buck Converters
- Computing Point of Load
- Communications Power Supplies
Procurement Notes
Verify the component against the official onsemi datasheet PDF NTMFD1D6N03P8-D.pdf. Confirm the device marking D1D6 matches the physical part. Ensure the package type is PQFN8 Power Clip (CASE 483AR). Check that the ordering suffix corresponds to the 3000-unit reel quantity specified in the manufacturer's documentation.
Selection Notes
Select this component when designing synchronous buck converters requiring integrated control and synchronous switches. The asymmetric rDS(on) values allow optimization for different current paths within the converter topology. Evaluate thermal resistance parameters based on the specific copper pad area and FR-4 board material used in the application design.
Part Context
This device belongs to onsemi's PowerTrench family utilizing Power Clip technology. It is designed specifically for point-of-load applications where space constraints and switching efficiency are critical. The integration of two specialized N-Channel MOSFETs into a single package reduces the overall footprint compared to discrete solutions.
Replacement Considerations
Direct substitutes must match the dual N-channel configuration, 30V rating, and PQFN8 Power Clip package. Verify that alternative components offer comparable rDS(on) values for both the control and synchronous legs to maintain the intended efficiency profile of the synchronous buck converter design.
