Product details
Overview
NSV40501UW3T2G from onsemi is an AEC-Q101 qualified NPN bipolar junction transistor in a WDFN3 package, rated for 40 V VCEO, 5.0 A continuous collector current, and ultra-low 38 mΩ equivalent RDS(on) with VCE(sat) as low as 6 mV at IC = 0.1 A / IB = 10 mA. It serves as a high-efficiency, low-voltage switching device in automotive airbag deployment circuits and portable DC-DC converters.
For engineers reviewing the NSV40501UW3T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q101 qualification, 143 °C/W RJA (FR-4, 100 mm²), 150 MHz fT, and direct drive capability from PMU control outputs without external base resistors.
Technical Context
This transistor operates in saturation mode for high-efficiency switching, with linear hFE (200–320) enabling analog amplifier use and stable gain across IC = 10 mA to 3.0 A. Its ultra-low VCE(sat) minimizes conduction loss in battery-powered systems where thermal headroom is constrained.
The WDFN3 package features an exposed thermal pad (RJL = 23 °C/W) and supports high-current density operation up to 7.0 A peak. Switching performance is characterized with td = 90 ns, tr = 100 ns, ts = 1050 ns, and tf = 100 ns under VCC = 30 V, IC = 750 mA conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive and 12 V industrial rails. |
| IC (continuous) | 5.0 A - Sustained current-handling capacity with 875 mW dissipation on FR-4 (100 mm²); defines thermal design baseline. |
| VCE(sat) @ IC/IB = 10 | 38 mV typical - Ultra-low saturation voltage reduces power loss to <190 mW at 5 A, critical for thermally constrained PCBs. |
| hFE | 200–320 - High, linear DC current gain allows direct PMU output drive and stable analog amplification without gain compression. |
| fT | 150 MHz - Enables high-speed switching in DC-DC controllers operating up to ~15 MHz fundamental frequency. |
| RJL | 23 °C/W - Low junction-to-lead thermal resistance via exposed pad; supports >1.5 W dissipation with adequate copper area. |
Pinout & Package
NSV40501UW3T2G uses the WDFN3 (Case 506AU) 2×2 mm surface-mount package with an exposed thermal pad. Pin 1 is Collector, Pin 2 is Base, Pin 3 is Emitter - confirmed by marking diagram and mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Main current input node; connected to load or supply rail; requires thermal relief and current-carrying trace width ≥0.8 mm for 5 A. |
| 2 | Base | Control input; driven directly from PMU GPIO or logic-level signal; no series resistor needed due to high hFE. |
| 3 | Emitter | Current return path; tied to ground or low-side switch reference; must connect to large copper pour for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including airbag deployment and instrument cluster; supports PPAP documentation. |
| Ultra-low VCE(sat) | 6–160 mV range across operating currents; cuts conduction losses by >40% vs. standard BJT alternatives at 2–4 A loads. |
| High hFE linearity | 200–320 over IC = 10 mA–3 A; eliminates need for base current compensation networks in analog gain stages. |
| Exposed thermal pad | Enables 23 °C/W RJL; allows >1.5 W continuous dissipation with 500 mm² copper, reducing heatsink dependency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40501UW3T2G | Same die, non-automotive grade; lacks NSV prefix and AEC-Q101 certification. | Approved for consumer electronics only; not qualified for automotive safety-critical functions. | Select when cost sensitivity outweighs automotive qualification requirements. |
| Diodes Incorporated DXT75503Q-7 | 40 V/5 A NPN with 45 mV VCE(sat) at IC/IB = 10; SOT-23 package; RJA = 200 °C/W. | Limited to ≤1.2 W dissipation; unsuitable for sustained 5 A loads without forced cooling. | Choose for space-constrained, lower-power applications where thermal budget permits higher saturation loss. |
Compared with NSS40501UW3T2G and DXT75503Q-7, NSV40501UW3T2G delivers superior thermal performance (RJL = 23 °C/W), automotive qualification, and lower VCE(sat), making it the only option suitable for uncooled 5 A switching in safety-critical automotive modules.

FAQ
What is the maximum continuous collector current rating for NSV40501UW3T2G?
The NSV40501UW3T2G has a maximum continuous collector current (IC) rating of 5.0 A at TA = 25 °C with appropriate PCB copper area (100 mm², 1 oz). Derating applies above 25 °C at 7.0 mW/°C for standard layout or 11.8 mW/°C with enhanced thermal pads. This rating is validated per JEDEC JESD78 and supports sustained operation in automotive and industrial environments.
Is NSV40501UW3T2G qualified for automotive applications?
Yes, NSV40501UW3T2G carries the NSV prefix and is AEC-Q101 qualified for stress testing including HTGB, HTRB, and temperature cycling. It is PPAP-capable and approved for use in airbag deployment systems and instrument clusters. The "NSV" designation confirms automotive-specific site controls, change management, and traceability per IATF 16949 requirements.
What is the thermal resistance from junction to ambient for NSV40501UW3T2G?
NSV40501UW3T2G has two specified RJA values: 143 °C/W on FR-4 with 100 mm² copper (Note 2) and 85 °C/W on FR-4 with 500 mm² copper (Note 3). These values reflect real-world PCB thermal design impact-using larger copper pours reduces thermal impedance by >40%, enabling higher sustained power handling without active cooling.
Does NSV40501UW3T2G support analog amplifier operation?
Yes, NSV40501UW3T2G exhibits linear DC current gain (hFE) from 200 to 320 across IC = 10 mA to 3.0 A at VCE = 2.0 V, making it suitable for Class-A and Class-AB analog amplifier stages. Its low VBE(sat) (0.76–0.90 V) and stable beta reduce bias network complexity and improve gain consistency versus conventional BJTs.
What package type and pin configuration does NSV40501UW3T2G use?
NSV40501UW3T2G uses the WDFN3 (Case 506AU) 2×2 mm package with three terminals: Pin 1 = Collector, Pin 2 = Base, Pin 3 = Emitter. The exposed thermal pad (Pin 4, internal) is electrically connected to the collector and must be soldered to a thermal plane. Mechanical dimensions and solder footprint are defined in onsemi document 98AON21416D.
