Product details
Overview
NSV40301CTWG from onsemi is an AEC-Q101 qualified NPN bipolar power transistor in LFPAK4 5×6 package, rated for 40 V VCEO, 3.0 A continuous collector current, and ultra-low 0.200 V VCE(sat) at IC = 3.0 A / IB = 0.3 A. It delivers high hFE (100–600) and 215 MHz fT, targeting high-efficiency, space-constrained DC-DC converters in automotive powertrain control units and airbag deployment systems.
For engineers reviewing the NSV40301CTWG datasheet, pinout, applications, or equivalent options, key selection criteria include its wettable flanks for automated optical inspection, AEC-Q101 qualification status, ultra-low saturation voltage under high-current switching, and thermal resistance of 58 °C/W (junction-to-case).
Technical Context
This device belongs to onsemi's e2PowerEdge family of low-VCE(sat) transistors, optimized for high-speed switching in ≤40 V systems. Its LFPAK4 5×6 package integrates a thermally enhanced copper clip structure and wettable flanks-enabling both high power density and automotive-grade solder-joint inspection compliance.
The transistor exhibits strong DC current gain linearity across IC = 0.001–3.0 A (hFE = 600 down to 100), supports fast switching via 215 MHz fT and low Cib = 170 pF / Cob = 25 pF, and maintains stable VCE(sat) performance from –55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum blocking voltage before breakdown in common-emitter configuration; defines safe operating range in 12 V/24 V automotive rails. |
| IC (continuous) | 3.0 A - Sustained load current capability with thermal derating; enables compact 3 A switch without external heatsink in PCB-limited designs. |
| VCE(sat) @ 3.0 A | 0.200 V - Ultra-low saturation voltage reduces conduction loss to <600 mW, critical for >90% efficiency in synchronous buck stages. |
| hFE @ 3.0 A | 100–600 - Wide DC gain range ensures reliable base drive margin across production lots and temperature extremes. |
| fT | 215 MHz - Current-gain bandwidth product enabling clean turn-off in PWM frequencies up to ~20 MHz with minimal storage time. |
| RθJC | 58 °C/W - Low junction-to-case thermal resistance allows direct thermal coupling to copper pour or heatsink, supporting 2.0 W dissipation at TC = 25 °C. |
| AEC-Q101 | Qualified - Validated for automotive applications including powertrain ECUs and passive safety systems per stress test requirements. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 (Emitter) | Emitting terminal (common emitter connection) | Three parallel emitter pads reduce bond wire inductance and improve current sharing; tied internally to large copper area for low RESR. |
| 4 (Base) | Control input for transistor biasing | Single-base pad designed for low-inductance gate drive routing; requires ≤1.0 A peak base current per datasheet limits. |
| 5 (Collector) | Main power output terminal | Exposed copper collector pad serves as primary thermal path and high-current return; electrically and thermally coupled to PCB ground plane. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV40300CTWG | Complementary PNP device; same package, VCEO = 40 V, IC = 3.0 A, but VCE(sat) = 0.220 V @ 3.0 A and hFE = 60–300. | Used in complementary emitter-follower or H-bridge topologies where bidirectional current control is required. | Select NSV40300CTWG only when PNP polarity and matched thermal characteristics are needed alongside NSV40301CTWG. |
| DMT3006LPSQ-13 | 60 V, 3.0 A N-channel MOSFET in PowerSO-8; RDS(on) = 28 mΩ @ VGS = 10 V; no gate charge requirement but higher VGS(th) = 1–2.5 V. | Suitable for high-side switching or logic-level drive where gate voltage ≥4.5 V is available; lacks inherent current gain. | Choose DMT3006LPSQ-13 if gate drive voltage ≥10 V is available and zero gate current is preferred; NSV40301CTWG remains superior for low-voltage base drive (≤3.3 V MCU outputs). |
Compared with NSV40300CTWG and DMT3006LPSQ-13, the NSV40301CTWG offers highest current gain and lowest VCE(sat) among the three, making it optimal for low-voltage, high-current linear or quasi-saturated switching where base drive simplicity and thermal efficiency are prioritized over gate-drive flexibility.

FAQ
What is the maximum continuous collector current rating for NSV40301CTWG?
The NSV40301CTWG is rated for 3.0 A continuous collector current at TC = 25 °C with appropriate PCB copper area (1″ sq. FR-4). Derating applies above 25 °C per Figure 1; at TC = 100 °C, usable IC drops to approximately 1.2 A. This rating assumes proper thermal management using the exposed collector pad.
Does NSV40301CTWG support automotive qualification standards?
Yes, NSV40301CTWG is AEC-Q101 qualified and PPAP capable. The NSV prefix explicitly denotes automotive-grade manufacturing controls, including unique site traceability, enhanced process monitoring, and full stress-test validation per AEC-Q101 Rev D. It is approved for use in powertrain and passive safety systems.
What package type does NSV40301CTWG use, and why is it significant?
NSV40301CTWG uses the LFPAK4 5×6 (Case 760AB) package-a surface-mount, ultra-slim (0.65 mm) power package with wettable flanks. This enables automated optical inspection of solder joints and provides low RθJC = 58 °C/W, making it ideal for space-constrained, thermally demanding automotive modules.
How does the VCE(sat) of NSV40301CTWG compare to standard NPN transistors?
NSV40301CTWG achieves VCE(sat) = 0.200 V at IC = 3.0 A / IB = 0.3 A-up to 50% lower than typical SO-8 or TO-252 NPN transistors. This ultra-low saturation voltage directly reduces conduction losses and PCB heating, especially critical in battery-powered and engine-bay applications.
Can NSV40301CTWG be used as a direct replacement for NSS40301CT?
No-NSV40301CTWG and NSS40301CT share identical electrical specs and package, but differ in manufacturing flow and qualification: NSV denotes automotive-grade process controls and AEC-Q101 certification, while NSS is commercial-grade. They are not drop-in replacements unless the application requires automotive qualification.
