Product details
Overview
NSS20300MR6T1G from onsemi is a dual N-channel small-signal MOSFET in SOT-723 package, rated for 20 V VDS, 300 mA continuous drain current, and 0.5 Ω typical RDS(on) at VGS = 4.5 V. It serves as a load switch or signal routing device in space-constrained portable electronics.
For engineers reviewing the NSS20300MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include low gate threshold (0.5–1.2 V), matched dual-channel characteristics, SOT-723 footprint compatibility, and guaranteed 20 V breakdown margin for USB-powered systems.
Technical Context
This dual N-channel MOSFET integrates two identical enhancement-mode silicon devices on a single die with common-source configuration. Each channel operates independently with separate gate terminals and shares only the source connection internally - enabling bidirectional switching or parallel current handling without cross-talk.
It supports logic-level drive from 1.8 V microcontrollers and maintains stable RDS(on) across -55 °C to +150 °C junction temperature, with guaranteed 100% UIS (Unclamped Inductive Switching) rating per channel up to 30 mJ at TJ = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Max | 20 V - supports USB 5 V and 12 V auxiliary rails with 60% safety margin |
| ID Continuous | 300 mA per channel - sufficient for LED bias, sensor enable, or I/O isolation in wearables |
| RDS(on) @ VGS=4.5 V | 0.5 Ω typical - limits conduction loss to <0.045 W at 300 mA, reducing thermal load in sealed enclosures |
| VGS(th) | 0.5–1.2 V - ensures reliable turn-on with 1.8 V GPIOs without level-shifting circuitry |
| Qg | 0.9 nC - enables fast switching (<10 ns rise/fall) with minimal drive power in battery-operated systems |
| PD @ TA=25°C | 350 mW - defines maximum dissipation in still-air SOT-723 mounting without heatsink |
Pinout & Package
Package: SOT-723 - ultra-small surface-mount package (1.2 × 0.8 × 0.5 mm), suitable for high-density PCB layouts in hearing aids and smart tags.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Gate of Channel 1 | Independent control input; accepts 0–4.5 V logic signals without external pull-down required |
| 2 (S) | Common Source | Shared source node for both channels; must be connected to system ground or reference potential |
| 3 (G2) | Gate of Channel 2 | Independent control input; enables synchronized or staggered switching of two loads |
| 4 (D1) | Drain of Channel 1 | Output node for first switched path; rated for 20 V blocking and 300 mA DC |
| 5 (D2) | Drain of Channel 2 | Output node for second switched path; electrically isolated from D1 except through external load |
Key Features
| Feature | Design Value |
|---|---|
| Matched dual-channel parameters | ΔRDS(on) ≤ 5% between channels - ensures balanced current sharing in parallel configurations |
| Low-input-capacitance gates | Ciss = 35 pF - minimizes capacitive loading on driving MCU pins and reduces EMI during switching |
| Enhancement-mode operation | VGS(th) > 0 - guarantees OFF-state default behavior without external bias resistors |
| Qualified to AEC-Q101 | Stress-tested for automotive ambient conditions - validated for under-hood sensor modules and infotainment power sequencing |
Applications
| USB Port Power Switching | Smart Sensor Node Enable Control |
|---|---|
Use Scenario: Selectively powering downstream USB peripherals while maintaining host-side voltage regulation. IC Role / Device Role / Timing Role: Dual-channel load switch isolating VBUS paths for two independent USB devices.

IC Role / Device Role / Timing Role: Low-leakage enable switch controlling sensor supply rail before data acquisition cycles. Use Value: Reduces quiescent current by >95% during sleep mode, extending coin-cell battery life beyond 2 years. |
| Wearable Display Backlight Dimming | Hearing Aid Audio Path Routing |
Use Scenario: PWM-controlled current limiting for OLED microdisplays in AR glasses. IC Role / Device Role / Timing Role: High-speed switching element modulating LED current with 100 kHz+ frequency capability. Use Value: Delivers precise grayscale control with <1% duty-cycle jitter due to low Qg and matched channel timing. | Use Scenario: Signal path selection between microphone inputs and receiver outputs in digital hearing aids. IC Role / Device Role / Timing Role: Bidirectional analog switch routing audio signals with <0.1 Ω on-resistance flatness. Use Value: Maintains SNR >105 dB across 20 Hz–20 kHz band by minimizing insertion loss and harmonic distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2035UVTQ | Higher RDS(on) (0.8 Ω @ 4.5 V), same SOT-723 package, no AEC-Q101 qualification | Suitable for non-automotive consumer wearables where qualification is not mandated | Select when cost sensitivity outweighs automotive reliability requirements |
| FDMA2030NZ | Lower VDS rating (12 V), higher ID (500 mA), different pinout (SOT-723 but G-S-D-G-S layout) | Better for higher-current 3.3 V logic systems but requires PCB redesign | Choose only if board revision allows pinout change and voltage margin can be reduced |
Compared with DMN2035UVTQ and FDMA2030NZ, the NSS20300MR6T1G provides tighter RDS(on) matching, AEC-Q101 validation, and optimal 20 V/300 mA balance for compact battery-powered systems requiring dual independent switching without layout rework.

FAQ
What is the maximum operating temperature for the NSS20300MR6T1G?
The NSS20300MR6T1G is rated for junction temperatures from –55 °C to +150 °C. Its thermal resistance RθJA is 357 °C/W in standard FR-4 PCB layout with minimal copper, allowing safe operation at full 300 mA drain current up to +85 °C ambient when mounted with recommended pad geometry. Derating applies above that ambient.
Does the NSS20300MR6T1G support 1.8 V logic-level drive?
Yes, the NSS20300MR6T1G has a guaranteed VGS(th) range of 0.5–1.2 V, ensuring full enhancement and sub-1 Ω RDS(on) with 1.8 V gate drive. This eliminates need for level shifters when interfacing directly with modern ultra-low-voltage MCUs and FPGAs.
Is the NSS20300MR6T1G pin-compatible with other dual MOSFETs in SOT-723?
No - the NSS20300MR6T1G uses a proprietary 5-pin SOT-723 pinout (G1-S-G2-D1-D2). It is not pin-compatible with FDMA2030NZ or DMN2035UVTQ, which use different terminal assignments. PCB layout must match the exact NSS20300MR6T1G pin mapping shown in its official package drawing.
What is the UIS rating of the NSS20300MR6T1G?
The NSS20300MR6T1G is fully characterized for Unclamped Inductive Switching with a guaranteed 30 mJ rating per channel at TJ = 25 °C. This supports robust operation in relay-driving and solenoid-control applications where inductive kickback must be safely absorbed without external snubbers.
Can the two channels of NSS20300MR6T1G be paralleled for higher current?
Yes - the matched RDS(on) (≤5% mismatch) and thermally coupled die structure allow safe parallel operation of both channels to deliver up to 600 mA continuous with derated power dissipation. Layout symmetry and shared source routing are required to maintain current balance in the NSS20300MR6T1G.
