Product details
Overview
PBSS4041NZ-Q from Nexperia is an AEC-Q101-qualified NPN low VCE(sat) transistor in SOT223 (SC-73) package, rated for 60 V VCEO, 7 A continuous collector current, and 17.5 mΩ typical RCE(sat) at IC = 6 A / IB = 600 mA. It serves as a high-efficiency power switch in automotive loadswitch and battery charging circuits.
For engineers reviewing the PBSS4041NZ-Q datasheet, PBSS4041NZ-Q pinout, PBSS4041NZ-Q application, or PBSS4041NZ-Q equivalent, this device is selected for low-loss switching in space-constrained 12 V/24 V automotive systems where thermal performance on FR4 PCBs and robust transient handling are critical.
Technical Context
This NPN transistor features a planar epitaxial die structure optimized for low saturation resistance and high hFE (50–240) at IC = 7 A, enabling efficient base drive with IB as low as 350 mA for full saturation. Its 15 A peak collector current rating supports motor startup surges and pulse-load conditions.
Thermal design is enabled by dual-collector terminals (Pins 2 & 4) and low Rth(j-sp) of 11 K/W, allowing >1.6 W dissipation on standard 4-layer FR4 PCBs. Transient thermal impedance curves confirm stable operation under 1 ms pulses with duty cycles down to 0.02.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum blocking voltage in common-emitter configuration; suitable for 24 V automotive systems with 2× supply margin. |
| IC | 7 A continuous - Sustained load current capability without derating at Tamb ≤ 25 °C on 4-layer FR4 PCB. |
| RCE(sat) | 17.5 mΩ typ - Enables <125 mV VCE(sat) at 7 A, reducing conduction loss to <0.875 W vs. >2 W for conventional transistors. |
| hFE | 50–240 - High DC current gain at high IC allows simplified base drive circuitry with minimal gate driver overhead. |
| toff | 1220 ns - Fast turn-off time supports PWM switching up to ~100 kHz in power management applications. |
| Tj(max) | 150 °C - Junction temperature limit aligned with AEC-Q101 automotive qualification for under-hood deployment. |
Pinout & Package
SOT223 (SC-73) plastic surface-mount package with 4 leads, 2.3 mm pitch, and integrated heatsink pad (Pins 2 & 4 both connected to collector). Body dimensions: 6.5 mm × 3.5 mm × 1.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring 350–600 mA drive for full saturation at 7 A collector current. |
| 2 | Collector | Main high-current output terminal; electrically tied to Pin 4 for enhanced thermal and current-handling capability. |
| 3 | Emiter | Reference node for load return path; internally connected to PCB ground plane via exposed pad in standard layout. |
| 4 | Collector | Second collector terminal providing parallel current path and improved thermal coupling to PCB copper area. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 125 mV max at IC = 7 A / IB = 350 mA reduces power loss by >50% versus standard bipolar transistors. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| Dual-collector terminals | Pins 2 & 4 enable 2× current sharing and lower effective Rth(j-a) (75 K/W on 6 cm² FR4 pad). |
| High hFE at high IC | Min 50 at IC = 7 A ensures reliable saturation with moderate base drive, simplifying driver IC selection. |

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 NSS40401MZ4T1G | Same SOT223 package, but 40 V VCEO, 4 A IC, 35 mΩ RCE(sat); lower voltage/current rating. | Restricted to 12 V systems only; unsuitable for 24 V automotive loads or 7 A continuous operation. | Select only for cost-sensitive 12 V consumer electronics where 60 V margin is unnecessary. |
| Diodes Incorporated DXT7050QZ-13 | 60 V VCEO, 5 A IC, 22 mΩ RCE(sat); AEC-Q101 qualified but no dual-collector terminals. | Limited to 5 A loads; higher thermal resistance (Rth(j-a) = 90 K/W) requires larger PCB copper area for same power dissipation. | Choose when footprint compatibility is critical but peak current and thermal headroom are less demanding. |
Compared with NSS40401MZ4T1G and DXT7050QZ-13, PBSS4041NZ-Q delivers 40% higher continuous current, 25% lower RCE(sat), and superior thermal performance via dual-collector construction-making it the only option qualified for 7 A automotive loadswitching with minimal board area.

FAQ
What is the maximum allowable base current for PBSS4041NZ-Q?
The absolute maximum base current is 1 A per datasheet Table 5. However, for reliable 7 A collector conduction with margin, the recommended continuous base drive is 350–600 mA. Exceeding 600 mA offers diminishing saturation improvement while increasing base drive losses and thermal stress on the control circuit.
Can PBSS4041NZ-Q be used in high-frequency PWM applications above 50 kHz?
Yes-its 1220 ns turn-off time and 100 MHz fT support PWM operation up to 100 kHz. However, due to its bipolar nature, switching losses increase significantly above 50 kHz; optimal efficiency is achieved at 1–20 kHz for motor control or 100–500 kHz for resonant topologies where gate charge is not a factor.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 must be routed to the same high-current net and connected to a shared thermal pad (≥1 cm² on 4-layer FR4 or ≥6 cm² on single-layer). This configuration halves effective current density and reduces thermal resistance by up to 30% compared to single-collector SOT223 devices.
Is PBSS4041NZ-Q pin-compatible with its PNP complement PBSS4041PZ-Q?
Yes-both share identical SOT223 (SC-73) pinout: Pin 1 = Base, Pins 2 & 4 = Collector (NPN) / Emitter (PNP), Pin 3 = Emitter (NPN) / Collector (PNP). This enables symmetrical high-side/low-side driver designs with matched thermal and electrical characteristics.
