Product details
Overview
PBSS302NDH from Nexperia is an NPN low VCE(sat) transistor in TSOP6 (SOT457) package, rated for 40 V VCEO, 4 A continuous collector current, and 15 A peak pulse current. It delivers ultra-low saturation resistance (55–75 mΩ at IC = 6 A), enabling high-efficiency power switching in compact DC-DC converters and motor drive stages.
For engineers reviewing the PBSS302NDH datasheet, PBSS302NDH pinout, PBSS302NDH application, or PBSS302NDH equivalent, key selection criteria include verified VCE(sat) ≤ 450 mV at 4 A, thermal resistance as low as 113 K/W on 6 cm² FR4, and validated 6-pin TSOP6 layout compatibility with gate-drive and load-switch PCB footprints.
Technical Context
This device operates as a high-current, low-loss NPN switch optimized for saturated-mode operation. Its design emphasizes minimal conduction loss via ultra-low RCE(sat) and tight VCE(sat) distribution (100–190 mV at 4 A), supported by robust 150 °C junction temperature rating and pulsed switching capability (tp ≤ 1 ms).
Thermal performance is defined across multiple mounting conditions: ceramic PCB (350 K/W), standard FR4 (208 K/W), and enhanced FR4 with 6 cm² collector pad (113 K/W). Switching parameters include ton = 64 ns and toff = 510 ns under 10 V/2 A test conditions, confirming suitability for medium-frequency (<1 MHz) switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage with base open; defines maximum blocking capability in low-side switch configurations. |
| IC (continuous) | 4 A - Sustained DC current handling on ceramic PCB; enables direct replacement of TO-236 devices in space-constrained 5–12 V power rails. |
| RCE(sat) | 55–75 mΩ - Measured at IC = 6 A, IB = 600 mA, pulsed; directly determines conduction loss (Pcond ≈ I² × R) in high-current paths. |
| VCE(sat) | 100–190 mV at IC = 4 A - Confirmed saturation voltage range ensures <0.76 W dissipation at full load, reducing heatsink requirements. |
| fT | 150 MHz - Transition frequency at VCE = 10 V, IC = 0.1 A; supports fast switching with minimal storage time (ts = 390 ns). |
| toff | 510 ns - Turn-off time under VCC = 10 V, IC = 2 A, IBoff = −0.1 A; enables efficient operation up to ~500 kHz PWM frequencies. |
Pinout & Package
TSOP6 (SOT457) plastic surface-mount package with 6 leads, 1.3 mm profile, and standardized reflow footprint (3.45 mm × 1.95 mm). Pin 1 index located at top-left corner; pins 1, 2, 5, and 6 are internally connected to collector for enhanced current sharing and thermal spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector (C) | Four parallel collector terminals reduce bond-wire inductance and improve current derating; enable >4 A routing without trace overheating. |
| 3 | Base (B) | Single control input requiring 400 mA drive at 4 A IC; designed for direct connection to logic-level or dedicated gate drivers. |
| 4 | Emiter (E) | Common emitter reference; must be routed with low-inductance path to ground plane to maintain switching stability and minimize VBE error. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VCE(sat) | 100–190 mV at 4 A ensures <0.76 W conduction loss-critical for thermally constrained battery-powered systems. |
| Multi-collector pin architecture | Four collector terminals (pins 1/2/5/6) distribute current and lower effective thermal resistance by up to 46% vs. single-pin SOT-23 equivalents. |
| High peak current capability | 15 A single-pulse rating (tp ≤ 1 ms) supports inrush current handling in motor startup and hot-swap circuits. |
| Optimized for FR4 PCBs | Thermal resistance as low as 113 K/W with 6 cm² copper pad-enables reliable 4 A operation without ceramic substrates. |
Applications
| Motor Drive Stage | USB-C Power Delivery Switch |
|---|---|
|
Use Scenario: Low-side switching for 12 V brushed DC fans and small pumps in industrial controllers. IC Role / Device Role / Timing Role: NPN power switch controlling motor current path; operates in saturated mode with <200 mV drop at full load.

| DC-DC Synchronous Rectifier | MOSFET Gate Driver |
|

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 NSS30201MR6T1G | Same TSOP6 package, but rated for 30 V VCEO and 2 A IC; VCE(sat) = 120–200 mV at 2 A. | Limited to ≤30 V systems; insufficient for 40 V automotive or industrial bus interfaces. | Select only when system voltage ≤30 V and current demand ≤2 A-offers tighter VCE(sat) tolerance but lower voltage margin. |
| Diodes Incorporated DXT3020N6T | TSOP6 package, 40 V VCEO, 4 A IC, but higher VCE(sat) (180–300 mV at 4 A) and no multi-collector pinout. | Higher conduction loss (~1.2 W vs. 0.76 W) requires larger copper area or forced cooling at full load. | Acceptable where cost is prioritized over thermal performance; not recommended for sealed enclosures or high ambient temperatures. |
Compared with NSS30201MR6T1G and DXT3020N6T, PBSS302NDH uniquely combines 40 V rating, 4 A capability, sub-200 mV VCE(sat), and four-collector thermal architecture-making it the only option supporting 4 A continuous operation on standard FR4 without auxiliary cooling.

FAQ
What is the maximum continuous collector current for PBSS302NDH under standard PCB conditions?
The PBSS302NDH supports 4 A continuous collector current when mounted on a ceramic PCB (Al₂O₃) with standard footprint, per datasheet Section 4. On standard FR4 with tin-plated single-sided copper, derating applies: 3.6 A at 25 °C ambient, decreasing linearly to 2.2 A at 75 °C ambient per Figure 1 power derating curves.
Can PBSS302NDH replace a MOSFET in low-side switching applications?
Yes-PBSS302NDH is frequently used as a MOSFET replacement in low-side switches where gate drive complexity, cost, or board space must be minimized. Its 100–190 mV VCE(sat) at 4 A yields lower conduction loss than many 20–30 V logic-level MOSFETs with RDS(on) > 20 mΩ, especially below 5 A. However, it lacks MOSFET's voltage-controlled operation and requires sustained base current.
How does the four-collector pin configuration affect PCB layout?
The four collector pins (1, 2, 5, 6) must be connected to a common high-current copper pour-ideally ≥6 cm² on FR4-to achieve the 113 K/W thermal resistance. Splitting or narrow traces between pins increases localized heating and degrades RCE(sat) consistency. The layout must mirror the TSOP6 footprint in Figure 16 (reflow) with 0.45 mm solder paste openings per pad.
Is PBSS302NDH qualified for automotive applications?
No-per Section 14 revision history, PBSS302NDH was explicitly changed to non-automotive qualification in v.4 (October 2024). It is not AEC-Q101 qualified, lacks automotive-grade screening, and is not tested to automotive temperature or reliability standards. For automotive use, Nexperia recommends the -Q qualified variant PBSS302ND-Q.
