Product details
Overview
NSS30071MR6T1G from onsemi is a 30 V, 4.5 A N-channel enhancement-mode MOSFET in SOT-23 package, featuring 32 mΩ RDS(on) at VGS = 10 V, 1.8 V gate threshold, and 1.4 nC total gate charge - optimized for low-side load switching in portable power management and USB port protection circuits.
For engineers reviewing the NSS30071MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its logic-level drive capability, compact SOT-23 footprint, low conduction loss at 3.3 V/5 V control, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET operates as a single N-channel switch with enhancement-mode behavior, requiring positive gate-to-source voltage to conduct. Its 1.8 V VGS(th) enables direct interface with 1.8 V and 3.3 V microcontrollers without level-shifting circuitry.
The device uses Trench technology for reduced RDS(on) and improved switching efficiency. It supports continuous drain current up to 4.5 A at TA = 25 °C with thermal resistance RθJA = 200 °C/W in standard PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - maximum drain-source blocking voltage for 12 V/24 V system-level load switching |
| RDS(on) @ VGS = 10 V | 32 mΩ - low conduction loss enabling <150 mW I²R heating at 2 A DC load |
| RDS(on) @ VGS = 4.5 V | 48 mΩ - verified operation under 3.3 V GPIO drive with acceptable on-state loss |
| VGS(th) | 1.0–2.5 V - ensures turn-on compatibility with 1.8 V and 3.3 V logic families |
| Qg | 1.4 nC - low gate charge reduces driver power and enables fast 20 ns ton/toff |
| PD (TA = 25 °C) | 0.5 W - defines maximum continuous power dissipation in SOT-23 without heatsink |
Pinout & Package
Package: SOT-23 (TO-236AB), surface-mount, 3-pin plastic package with standard JEDEC outline and thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for load current | Connected to ground or common reference; ties directly to PCB ground plane for thermal and EMI control |
| 2 (Gate) | Control input terminal | High-impedance node requiring minimal drive current; routed away from noisy signals to prevent false turn-on |
| 3 (Drain) | Load connection point | Carries full switched current; requires adequate copper area for thermal dissipation and voltage standoff |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS ≥ 2.5 V, eliminating need for gate boosters in 3.3 V systems |
| AEC-Q101 qualified | Validated for automotive applications including body control modules and infotainment power rails |
| Low Qg/Qsw ratio | Enables high-efficiency PWM switching up to 1 MHz with minimal driver losses |
| 100 % Rg tested | Guarantees consistent gate resistance for predictable turn-on timing across production lots |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | RDS(on) = 25 mΩ @ 10 V; SO-8 package; higher current rating (6.5 A) | Requires PCB area for SO-8; better suited for higher-power industrial loads | Select when >4.5 A continuous current or dual-MOSFET half-bridge layout is needed |
| SI2307DS-T1-GE3 | RDS(on) = 55 mΩ @ 4.5 V; same SOT-23 package; no AEC-Q101 qualification | Limited to commercial temperature range (–55 °C to +150 °C); lower gate drive margin at 3.3 V | Choose for cost-sensitive consumer designs where automotive qualification is unnecessary |
Compared with DMN3025LSD-13 and SI2307DS-T1-GE3, the NSS30071MR6T1G delivers optimal balance of automotive-grade reliability, logic-level drive, and SOT-23 space efficiency - making it preferred for space-constrained, safety-aware 12 V/24 V load switching where gate drive voltage is ≤3.3 V.

FAQ
What is the maximum continuous drain current rating for NSS30071MR6T1G at 85 °C ambient?
The NSS30071MR6T1G supports 3.2 A continuous drain current at TA = 85 °C with standard 1-inch² FR-4 PCB copper area. This derating from the 4.5 A @ 25 °C spec accounts for thermal resistance increase and ensures safe junction temperature below 150 °C under typical operating conditions. The NSS30071MR6T1G datasheet specifies this value in the "Steady-State Electrical Characteristics" table.
Does NSS30071MR6T1G require a gate resistor for ESD protection or switching control?
No external gate resistor is required for basic switching, but a 10–100 Ω series resistor is recommended to dampen ringing and limit peak gate current during fast edge transitions. The NSS30071MR6T1G integrates robust HBM ESD protection (±2 kV) per JESD22-A114, so no additional ESD diode is needed. Use of a resistor improves reliability in noisy environments without compromising NSS30071MR6T1G turn-on speed.
Is NSS30071MR6T1G suitable for reverse polarity protection circuits?
No - the NSS30071MR6T1G is an N-channel MOSFET intended for low-side switching only and lacks intrinsic body diode orientation for reverse polarity protection. For that function, a P-channel device like the NVMFS5C464NL or discrete P-FET solution is required. The NSS30071MR6T1G body diode conducts from source to drain, making it unsuitable for high-side reverse-blocking configurations.
What is the typical gate-to-source leakage current of NSS30071MR6T1G at 25 °C?
The typical gate-to-source leakage current (IGSS) for NSS30071MR6T1G is 10 nA at VGS = ±20 V and TJ = 25 °C, as specified in the "DC Electrical Characteristics" section of the official onsemi datasheet. This ultra-low leakage supports reliable hold-time in battery-critical applications and contributes to the NSS30071MR6T1G's suitability for always-on sensor node power gating.
Can NSS30071MR6T1G be used in PWM dimming circuits for LED backlighting?
Yes - the NSS30071MR6T1G supports PWM frequencies up to 1 MHz due to its 1.4 nC gate charge and fast 20 ns turn-on/turn-off times. When used as a low-side LED current switch, it maintains linear dimming response and low thermal rise at duty cycles ≥10 %. Ensure gate drive strength meets dV/dt requirements; the NSS30071MR6T1G performs reliably in 200 kHz–500 kHz backlight dimming topologies.
