Product details
Overview
PSMN3R3-100SSF from Nexperia is a 100 V, 3.3 mΩ RDS(on), 180 A continuous N-channel MOSFET in LFPAK88 (SOT1235) package, qualified to 175 °C junction temperature and optimized for high-efficiency switching in high-current DC-DC converters and motor drives.
For engineers reviewing the PSMN3R3-100SSF datasheet, PSMN3R3-100SSF pinout, PSMN3R3-100SSF application, or PSMN3R3-100SSF equivalent, key selection criteria include its low QG×RDS(on) figure of merit (106 nC × 3.3 mΩ), strong unclamped avalanche rating (478 mJ), and mounting-base thermal resistance (0.25 K/W).
Technical Context
This NextPower MOSFET employs a trench-gated superjunction structure enabling low on-resistance with fast switching dynamics. Its gate threshold voltage (2–4 V typ.) supports standard-level 10 V gate drive, and the integrated source-drain diode exhibits 46 nC recovered charge and 46 ns reverse recovery time at 25 °C.
The device features a thermally enhanced LFPAK88 package with drain-connected mounting base, delivering 341 W total power dissipation at Tmb = 25 °C and supporting pulsed peak current up to 848 A. Avalanche ruggedness is 100% production-tested per IEC 60134.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V maximum drain-source voltage - supports primary-side switching in 48 V and 60 V industrial DC-DC systems. |
| RDS(on) | 3.3 mΩ typical at VGS = 10 V, Tj = 25 °C - enables <1.7 W conduction loss at 180 A continuous operation. |
| ID | 180 A continuous drain current at Tmb = 25 °C - validated under application test conditions with thermal derating above 25 °C mounting base temperature. |
| QG(tot) | 106 nC typical total gate charge - balances switching speed and gate driver power requirements in hard-switched topologies. |
| EAS | 478 mJ non-repetitive avalanche energy - provides robustness against inductive turn-off transients without external snubbers. |
| Rth(j-mb) | 0.25 K/W typical junction-to-mounting-base thermal resistance - enables direct heatsink attachment for high-power density designs. |
| Qr | 46 nC source-drain diode recovered charge - reduces switching losses in synchronous rectification and half-bridge freewheeling. |
Pinout & Package
LFPAK88 (SOT1235) is a 4-lead, single-ended surface-mount package with 8 mm × 8 mm × 1.6 mm body, featuring an exposed copper mounting base electrically connected to the drain terminal for low-inductance, high-current routing and enhanced thermal transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | G | Gate input - accepts standard 10 V logic-level drive; 0.8 Ω typical gate resistance minimizes ringing. |
| 2 | S | Source return path - internally bonded to two parallel source terminals (pins 2 and 3) for low-inductance current return. |
| 3 | S | Source return path - redundant source connection improves current sharing and reduces package inductance. |
| 4 | mb | Mounting base - electrically tied to drain; serves as primary thermal interface and high-current drain node. |
Key Features
| Feature | Design Value |
|---|---|
| Low Qrr | 46 nC recovered charge - reduces diode switching losses and EMI in synchronous rectifier applications. |
| High avalanche energy rating | 478 mJ unclamped EAS - eliminates need for external avalanche protection in motor control and power supply clamping circuits. |
| Optimized FOM | 106 nC × 3.3 mΩ = 349.8 nC·mΩ - delivers superior efficiency in high-frequency, high-current buck and full-bridge converters. |
| 175 °C rated junction | Full 180 A current capability maintained up to Tj = 175 °C - enables compact thermal design in sealed industrial enclosures. |
| RoHS-compliant LFPAK88 | Halogen-free, lead-free construction with 260 °C peak soldering tolerance - compatible with standard reflow profiles and IPC-A-610 Class 3 assembly. |

FAQ
What is the maximum continuous drain current at 100 °C mounting base temperature?
The datasheet specifies 150 A continuous drain current at Tmb = 100 °C (Fig. 2), reflecting thermal derating from the 180 A rating at 25 °C. This value is validated under real-world PCB thermal conditions using a 25.4 mm square copper pad on FR4.
Does PSMN3R3-100SSF require gate resistors for stability in hard-switched applications?
Yes - due to its low gate resistance (0.8 Ω typ.) and high dV/dt immunity, a 5 Ω external gate resistor is recommended (per Fig. 14 test condition) to dampen ringing and control switching speed, especially in full-bridge configurations with high stray inductance.
Can this MOSFET be used in paralleled configurations?
Yes - its positive RDS(on) temperature coefficient (Fig. 13) ensures inherent current sharing when paralleled. Designers must match gate drive loop inductance and use Kelvin source connections to maintain balance under dynamic load conditions.
Is the mounting base electrically isolated from other pins?
No - the mounting base (pin 4) is internally connected to the drain terminal. It must be electrically isolated from the PCB ground plane unless the drain node is at system ground potential; thermal interface material must be electrically insulating if isolation is required.
