Product details
Overview
PBSS301ND,115 from NXP Semiconductors is an NPN low VCE(sat) Breakthrough in Small Signal (BISS) transistor in SOT457 (SC-74) package, rated for 20 V VCEO, 4 A continuous collector current, and 50–70 mΩ RCE(sat) at IC = 4 A / IB = 400 mA. It serves as a high-efficiency power switch in DC-DC converters, MOSFET gate drivers, and TFT backlight inverters.
For engineers reviewing the PBSS301ND,115 datasheet, PBSS301ND,115 pinout, PBSS301ND,115 application, or PBSS301ND,115 equivalent, this page delivers verified electrical specs, thermal derating behavior, switching timing (td = 12 ns, toff = 280 ns), package footprint details, and validated alternatives for power-switching BOM optimization.
Technical Context
This BISS transistor uses a proprietary epitaxial structure to achieve ultra-low saturation voltage and resistance-VCE(sat) = 200–280 mV and RCE(sat) = 50–70 mΩ at full 4 A load-enabling reduced conduction loss and thermal stress in high-current switching nodes. Its 6-pin SOT457 layout integrates four collector terminals (pins 1,2,5,6) for enhanced current handling and thermal spreading.
With hFE = 200–310 at IC = 4 A and fT = 100 MHz, it supports fast switching in PWM-driven loads while maintaining robust DC gain under high-current bias. The device operates across −65 °C to +150 °C junction temperature and features VEBO = 5 V and ICBO ≤ 0.1 µA (Tj = 25 °C), ensuring stable cutoff in noisy power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in 12 V/19 V power stages. |
| IC (continuous) | 4 A - Continuous collector current rating on ceramic PCB; enables direct drive of small motors or LED strings without external heatsinking. |
| RCE(sat) | 50–70 mΩ - Confirmed at IC = 4 A / IB = 400 mA; reduces conduction loss to ≤1.12 W at full load, lowering thermal design burden. |
| toff | 280 ns - Measured turn-off time at VCC = 12.5 V, IC = 3 A; supports PWM frequencies up to ~350 kHz with minimal dead-time overhead. |
| hFE | 200–310 - DC current gain at VCE = 2 V, IC = 4 A; ensures reliable saturation with modest base drive (e.g., 400 mA from MCU GPIO or driver IC). |
| Ptot (FR4, 6 cm² pad) | 2.5 W - Maximum power dissipation with optimized copper area; allows >1.5× higher sustained power vs. standard FR4 footprint. |
| θj-a | 50 K/W - Junction-to-ambient thermal resistance under pulsed conditions (δ ≤10 %, tp ≤10 ms); critical for short-duration peak-load handling. |
Pinout & Package
The PBSS301ND,115 is housed in a SOT457 (SC-74) 6-lead surface-mount plastic package with exposed collector terminals for thermal and current-handling enhancement. Four pins (1,2,5,6) are internally connected to the collector, pin 3 is the base, and pin 4 is the emitter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector | Four parallel collector terminals reduce effective bond-wire resistance and improve thermal path to PCB copper; enable ≥4 A continuous operation without solder joint fatigue. |
| 3 | Base | Single control input requiring ~400 mA drive for full saturation at 4 A; compatible with logic-level drivers or buffered microcontroller outputs. |
| 4 | Emitter | Common emitter reference node; must be routed with low-inductance path to ground plane to maintain switching integrity and minimize VBE noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RCE(sat) | 50–70 mΩ at 4 A - Enables <1.2 W conduction loss, reducing heatsink requirements in space-constrained DC-DC modules. |
| High peak current capability | 15 A single-pulse - Supports motor startup surges and capacitor-charging transients without secondary overcurrent protection. |
| Optimized thermal interface | θj-sp = 45 K/W - Low junction-to-solder-point resistance allows efficient heat transfer directly into PCB copper, even without thermal vias. |
| Fast switching performance | ton = 48 ns, toff = 280 ns - Minimizes transition losses in high-frequency PWM applications such as TFT backlight dimming. |
| Wide operating temperature | −65 °C to +150 °C Tj - Qualified for industrial and automotive under-hood environments where ambient extremes demand robust parametric stability. |
Applications
| DC-DC Converter Switch | MOSFET Gate Driver |
|---|---|
Use Scenario: High-efficiency synchronous buck converter output stage in portable medical devices and industrial sensors. IC Role / Device Role / Timing Role: Main power switch controlling energy transfer from input to output inductor; operates at 300–500 kHz PWM. Use Value: 50 mΩ RCE(sat) cuts conduction loss by >40% versus standard 100 mΩ transistors, extending battery life and reducing thermal throttling. |
Use Scenario: Level-shifting and current-boosting stage driving high-capacitance N-channel MOSFET gates in motor control H-bridges. IC Role / Device Role / Timing Role: Active pull-down switch providing fast gate discharge path during MOSFET turn-off. Use Value: 280 ns toff ensures clean gate voltage collapse, preventing shoot-through in 20–100 kHz motor drives. |
| TFT Backlight Inverter | Power Switch for Fans/Motors |
Use Scenario: High-side switch in resonant inverter circuits powering CCFL or LED backlights in industrial HMIs and displays. IC Role / Device Role / Timing Role: Primary switching element modulating AC current through transformer primary winding. Use Value: 15 A peak rating handles inrush currents during cold-start, while low VCE(sat) minimizes audible transformer buzz from voltage ripple. |
Use Scenario: Direct-drive power switch for 12 V DC cooling fans and small brushed DC motors in network equipment and test instrumentation. IC Role / Device Role / Timing Role: On/off controller interfacing between microcontroller GPIO and motor/fan load. Use Value: 4 A continuous rating supports fan loads up to 48 W; integrated collector terminals eliminate need for external paralleling. |
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 NSS30100DZT6G | VCEO = 20 V, IC = 3.5 A, RCE(sat) = 60–90 mΩ (IC = 3.5 A); SOT-563 package (5-pin, smaller footprint) | Limited to 3.5 A continuous; lower thermal mass reduces pulse handling margin in motor start-up scenarios. | Select when board space is constrained and peak current stays below 12 A; verify PCB copper area matches thermal derating curves. |
| Diodes Incorporated DXT3010P5-13 | VCEO = 20 V, IC = 4 A, RCE(sat) = 65–95 mΩ (IC = 4 A); SOT-26 package (same pinout but no multi-collector layout) | Single collector terminal increases thermal resistance (θj-a = 200+ K/W on FR4), limiting sustained power to ~1.3 W without extra copper. | Prefer for cost-sensitive designs where 4 A load is intermittent; avoid in continuous 4 A applications without thermal vias or large pads. |
Compared with PBSS301ND,115, NSS30100DZT6G trades current headroom and thermal robustness for compactness, while DXT3010P5-13 lacks the multi-collector architecture needed for low-impedance PCB thermal coupling-making PBSS301ND,115 uniquely suited for thermally demanding 4 A switching nodes.

FAQ
What is the maximum allowable base current for continuous operation?
The absolute maximum DC base current is 0.8 A per the datasheet limiting values table. However, for reliable continuous 4 A collector operation, the recommended base drive is 400 mA-verified by RCE(sat) and hFE specs at that condition. Exceeding 0.8 A risks metallization electromigration and long-term parameter drift.
Can PBSS301ND,115 replace a standard bipolar transistor like BC817 in a 4 A switching application?
No-BC817 is rated for only 0.5 A continuous and has RCE(sat) > 300 mΩ at 0.5 A. PBSS301ND,115 delivers 4× higher current capacity and <1/5 the saturation resistance, making it functionally incompatible as a drop-in replacement. Circuit redesign-including base drive strength and PCB copper area-is required.
How does the 4-collector pin configuration affect PCB layout?
The four collector pins (1,2,5,6) must be tied together on the PCB using wide, low-impedance copper traces or polygons. This configuration lowers effective package resistance and spreads heat across multiple solder joints-reducing localized thermal stress and improving reliability under 4 A continuous load.
Is PBSS301ND,115 suitable for automotive applications per AEC-Q101?
No-the PBSS301ND,115 is not AEC-Q101 qualified. While its −65 °C to +150 °C junction temperature range meets automotive ambient requirements, it lacks the stress-test validation (HTOL, TC, UHAST) and traceability controls mandated for automotive-grade discrete transistors.
