FDMS6681Z selection and design context
FDMS6681Z is cataloged as a P-Channel MOSFET in the PowerTrench family. Its recorded function is -30 V P-channel shielded-gate PowerTrench MOSFET with very low on-resistance. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Drain-Source Voltage: -30 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Continuous Drain Current: -21.1 A board limited. Check steady-state, transient and thermal margin in the intended operating mode.
- RDS(on): 3.2 mΩ maximum at -10 V gate drive. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Technology: Shielded-gate PowerTrench. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this switching device, confirm voltage and current margin, gate-drive conditions, on-state loss, switching energy, thermal impedance and safe operating area. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for FDMS6681Z
The recorded package is 8-lead WDFN Power56, 5 mm × 6 mm, the temperature range is -55°C to +150°C junction, and the lifecycle status is Production as of 2026-07-20.
