Product details
Overview
NMSD200B01 from Diodes Incorporated is a dual-function synchronous rectifier IC integrating an ESD-protected N-channel MOSFET (VDSS = 60 V, RDS(ON) = 1.5 Ω @ VGS = 10 V) and a low-VF Schottky diode (VF = 0.37 V @ 20 mA) in a single SOT-363 package. It delivers 200 mA continuous output current and targets DC-DC converter stages in Voltage Regulator Modules (VRMs).
For engineers reviewing the NMSD200B01 datasheet, NMSD200B01 pinout, NMSD200B01 application, or NMSD200B01 equivalent, key selection criteria include integrated MOSFET+Schottky co-location, low conduction loss (RDS(ON) + VF), thermal resistance (RθJA = 625 °C/W), and SOT-363 surface-mount compatibility with automated assembly.
Technical Context
The NMSD200B01 combines two discrete power devices - an ESD-protected N-MOSFET (Q1) and a Schottky barrier diode (D1) - in one monolithic SOT-363 package. Its architecture eliminates external gate drive coordination while preserving independent control of each sub-device's conduction path.
It operates as a synchronous rectification pair: the MOSFET handles primary switching with low RDS(ON) and fast turn-on/turn-off times (td(on) ≤ 20 ns, td(off) ≤ 40 ns), while the Schottky diode provides body-diode redundancy and low forward voltage (VF ≤ 0.6 V @ 200 mA) for reverse recovery immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum drain-source blocking capability for VRM high-side or low-side switch node placement |
| RDS(ON) | 1.5 Ω @ VGS = 10 V - Enables <150 mW conduction loss at 200 mA, critical for thermally constrained VRM layouts |
| VF (Schottky) | 0.37 V @ 20 mA - Reduces forward drop by ~30% vs. standard silicon diodes, lowering heat generation in freewheeling paths |
| IOUT | 200 mA continuous - Matches typical current requirements of point-of-load (POL) regulators in compact embedded systems |
| RθJA | 625 °C/W - Defines thermal derating on FR-4 PCBs; limits usable power to ~160 mW at TA = 85°C |
| trr (Schottky) | 10 ns - Ensures negligible reverse recovery charge in high-frequency (>500 kHz) DC-DC topologies |
| VGS(th) | 1.6 V typical - Allows reliable turn-on with standard 3.3 V or 5 V logic-level gate drives without level-shifting |
Pinout & Package
Package: SOT-363 - 6-pin surface-mount plastic package with 0.65 mm lead pitch, UL 94V-0 rated molding compound, and matte tin-plated terminals solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MOSFET Source | Common source node for N-MOSFET; electrically tied to Schottky cathode in internal layout |
| 2 | MOSFET Gate | ESD-protected control input; accepts 0–20 V gate drive with 1.6 V threshold |
| 3 | Schottky Anode | Freewheeling current entry point; isolated from MOSFET drain for independent biasing |
| 4 | MOSFET Drain / Schottky Cathode | Shared terminal - connects MOSFET drain and Schottky cathode internally; main power output node |
| 5 | No Connect | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling |
| 6 | MOSFET Source | Redundant source connection; electrically identical to Pin 1 and used for thermal and current sharing |
Key Features
| Feature | Design Value |
|---|---|
| Integrated ESD-protected N-MOSFET | Withstands ±20 V gate-source stress and 1 μA leakage at VGS = 0 V, enabling robust operation in noisy VRM environments |
| Co-packaged Schottky diode | 40 V VRRM, 0.37 V VF @ 20 mA, and 10 ns trr - eliminates need for external catch diode in buck converters |
| Low static conduction loss | Combined RDS(ON) + VF yields <0.9 V effective forward drop at 200 mA, reducing I²R heating in POL modules |
| SOT-363 footprint | 2.2 × 2.1 mm outline with 0.65 mm pitch - supports high-density PCB layouts and reflow-compatible automated assembly |
Applications
| Voltage Regulator Module (VRM) | Point-of-Load (POL) Converter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 12 V → 3.3 V VRM for CPU/GPU power delivery. IC Role / Device Role / Timing Role: Dual-function rectifier replacing discrete MOSFET + Schottky pair; operates at 300–600 kHz switching frequency.

| USB-C Power Delivery Sink | Industrial Sensor Node Power Supply |
Use Scenario: Buck converter stage regulating 9 V PD input to 3.3 V for USB-C peripheral logic. IC Role / Device Role / Timing Role: Integrated rectifier managing transient 200 mA peak loads during enumeration and data bursts. Use Value: ESD protection on gate and low VF prevent latch-up and voltage droop during hot-plug events. | Use Scenario: 24 V → 5 V step-down supply for battery-backed industrial temperature sensor nodes. IC Role / Device Role / Timing Role: High-reliability rectifier operating continuously at 85°C ambient with full derating. Use Value: -55°C to +150°C junction rating and halogen-free "Green" construction ensure long-term stability in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LKQ-7 | Single N-MOSFET (60 V, 1.8 Ω), no integrated Schottky diode; AEC-Q101 qualified | Requires external Schottky for freewheeling; suited for automotive-grade designs needing PPAP support | Select when automotive qualification and higher gate ruggedness outweigh integration benefit |
| SBM2040CLT3G | Standalone 40 V Schottky diode (0.45 V VF @ 200 mA); no MOSFET function | Cannot replace MOSFET switching action; only substitutes diode portion of NMSD200B01 | Select only for diode-only replacement where MOSFET is separately controlled |
Compared with DMN2004LKQ-7 and SBM2040CLT3G, the NMSD200B01 uniquely integrates both functions in one die, reducing BOM count and interconnect parasitics - critical for space-constrained VRMs where layout-induced ringing must be minimized.

FAQ
What is the maximum continuous current rating for the NMSD200B01?
The NMSD200B01 is rated for 200 mA continuous output current under standard conditions (TA = 25°C, FR-4 PCB with 1-inch² 2 oz copper). Derating applies above 25°C ambient, with full derating to zero at 85°C due to its 625 °C/W RθJA.
Can Pin 5 be left unconnected or must it be grounded?
Pin 5 is internally unconnected (NC) and must remain floating or be grounded per Diodes' layout recommendations. Connecting it to a signal net may introduce parasitic coupling or unintended current paths, degrading ESD performance and switching behavior.
How does the integrated Schottky diode interact with the MOSFET during switching transitions?
The Schottky diode (D1) and MOSFET (Q1) share the drain/cathode node (Pin 4) but have independent anode (Pin 3) and gate (Pin 2) terminals. During dead-time, D1 conducts freewheeling current until Q1 turns on; no cross-conduction occurs due to physical isolation of control and power paths.
Is the NMSD200B01 suitable for automotive applications?
The NMSD200B01 is not AEC-Q101 qualified. For automotive use, Diodes recommends contacting their sales team for PPAP-capable alternatives like the DMN2004LKQ-7, which offers equivalent voltage/current specs with full automotive qualification and IATF 16949 manufacturing.
