Product details
Overview
PBSS302ND,115 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 drivers.
For engineers reviewing the PBSS302ND,115 datasheet, PBSS302ND,115 pinout, PBSS302ND,115 application, or PBSS302ND,115 equivalent, key selection criteria include verified VCE(sat) ≤ 300 mV at 4 A, thermal resistance as low as 113 K/W on 6 cm² FR4, and confirmed 6-pin TSOP6 layout with 4 collector terminals for parallel current handling.
Technical Context
This device operates as a discrete NPN bipolar junction transistor optimized for low-loss switching in medium-power applications. Its architecture features four collector leads and one base/emitter pair, enabling distributed current handling and reduced trace resistance in PCB layouts.
It supports pulsed operation up to 15 A (tp ≤ 1 ms) and maintains VCE(sat) ≤ 190 mV at 4 A with 400 mA base drive under pulsed conditions (δ ≤ 0.02). Thermal performance is specified across multiple mounting configurations, including ceramic (Al₂O₃) and FR4 substrates with varying copper pad areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in 36 V automotive or industrial power rails. |
| IC (continuous) | 4 A - Sustained current capability on standard FR4 PCB; enables direct replacement of TO-236 devices without derating. |
| RCE(sat) | 55–75 mΩ - Measured at IC = 6 A, IB = 600 mA, pulsed; directly reduces conduction loss by >40% vs. standard BJT alternatives. |
| VCE(sat) | 100–190 mV - At IC = 4 A, IB = 400 mA, pulsed; ensures <0.76 W conduction loss at full load. |
| fT | 150 MHz - Transition frequency at VCE = 10 V, IC = 0.1 A; supports fast switching in PWM frequencies up to ~10 MHz. |
| toff | 510 ns - Turn-off time under VCC = 10 V, IC = 2 A, IBoff = −0.1 A; enables efficient operation in 500 kHz–1 MHz SMPS designs. |
Pinout & Package
Package: TSOP6 (SOT457), 6-lead surface-mount plastic package with 1.3 mm profile and 0.65 mm lead pitch; optimized for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Primary high-current output path; electrically tied to pins 2, 5, and 6 for parallel conduction and thermal spreading. |
| 2 | Collector | Redundant collector terminal; reduces effective bond wire resistance and improves current sharing in multi-amp switching. |
| 3 | Base | Control input requiring ≥400 mA pulsed drive for full saturation at 4 A; low VBE(sat) (1.0–1.1 V) minimizes driver loss. |
| 4 | Emitter | Reference node for current sensing and feedback; isolated from collector terminals to support high-side or low-side configurations. |
| 5 | Collector | Third collector connection; enhances thermal dissipation via internal die attach to exposed copper land in PCB footprint. |
| 6 | Collector | Fourth collector terminal; enables symmetric PCB layout with dual-sided copper pour for <113 K/W Rth(j-a) on 6 cm² FR4. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VCE(sat) | 100–190 mV at 4 A enables <0.76 W conduction loss, reducing heatsink requirements in space-constrained 5–24 V systems. |
| Quad-collector topology | Four collector terminals distribute current and lower effective package resistance, improving reliability under repetitive surge loads. |
| High peak current rating | 15 A single-pulse capability (tp ≤ 1 ms) supports motor startup surges and capacitor charging transients without secondary protection. |
| Optimized thermal interface | Thermal resistance as low as 113 K/W on 6 cm² FR4 allows 1.1 W continuous dissipation without forced airflow in industrial ambient (≤70 °C). |
Applications
| Motor Control Circuit | USB-C PD Power Path |
|---|---|

Use Scenario: Driving 12 V brushed DC fans or small stepper coil phases in HVAC or server cooling modules. IC Role / Device Role / Timing Role: Low-side power switch controlling current flow to inductive load; handles 4 A steady-state and 15 A startup peaks. Use Value: Sub-200 mV VCE(sat) limits temperature rise to <65 °C at 4 A on 2-layer FR4, eliminating need for external heatsinks. |
Use Scenario: Secondary-side synchronous rectification or load switching in 20–60 W USB-C Power Delivery adapters. IC Role / Device Role / Timing Role: High-efficiency pass transistor in constant-current/constant-voltage regulation loop; switches at 300–500 kHz. Use Value: 510 ns toff and 150 MHz fT ensure clean turn-off during fast transient response, minimizing cross-conduction loss. |
| DC-DC Buck Converter | MOSFET Gate Driver Stage |
|
Use Scenario: Main switching element in 5–12 V input, 3.3–5 V output buck regulators for FPGA or microcontroller power rails. IC Role / Device Role / Timing Role: Low-side switch in non-synchronous buck topology; conducts during freewheeling phase. Use Value: 75 mΩ RCE(sat) yields <1.2 W loss at 4 A, enabling >92% efficiency at 2 A load without complex gate drive circuitry. |
Use Scenario: Active pull-down stage in high-current MOSFET gate drivers for industrial inverters or servo amplifiers. IC Role / Device Role / Timing Role: Fast-turn-off clamp for Miller capacitance discharge; sinks ≥2 A peak gate current during transition.

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 NSS30200DZT1G | VCEO = 30 V, IC = 3.5 A, RCE(sat) = 85 mΩ @ 3.5 A - lower voltage rating and higher saturation resistance. | Limited to ≤24 V systems; requires larger gate drive due to higher VBE(sat) (~1.2 V). | Select when board space permits SO-8 and system voltage is capped at 24 V. |
| Diodes Incorporated DXT30200DE6327XTSA1 | VCEO = 40 V, IC = 4 A, RCE(sat) = 90 mΩ @ 4 A - 20% higher saturation resistance; no quad-collector layout. | Higher conduction loss increases thermal stress on 2-layer PCBs; lacks collector-terminal redundancy. | Choose only if TSOP6 footprint compatibility is not required and thermal margin exceeds 15 °C. |
Compared with NSS30200DZT1G and DXT30200DE6327XTSA1, PBSS302ND,115 delivers superior current density (4 A in TSOP6), lowest RCE(sat), and mechanical robustness via four collector terminals-making it optimal for thermally constrained, high-reliability 36 V industrial power stages.

FAQ
What is the maximum continuous power dissipation for PBSS302ND,115 on a standard FR4 PCB?
On a standard FR4 PCB (single-sided copper, tin-plated, no extended pad), PBSS302ND,115 has a Ptot rating of 360 mW at Tamb = 25 °C. This value scales with ambient temperature per the derating curve in Figure 1, reaching zero at ~125 °C ambient. For higher power, use extended copper pads (e.g., 6 cm²) to achieve up to 2.5 W under pulsed conditions.
Can PBSS302ND,115 be used in high-frequency switching applications above 1 MHz?
Yes-its 150 MHz fT and 510 ns toff support reliable operation up to ~1 MHz in hard-switched topologies. However, switching losses increase significantly above 500 kHz due to finite storage time (390 ns); for >1 MHz designs, consider pairing with active base clamping or using complementary MOSFETs where gate charge is lower.
Is PBSS302ND,115 automotive-qualified?
No-this part is explicitly marked as non-automotive qualified per Revision History (v.4, October 2024). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia offers the -Q qualified variant PBSS302ND,115-Q, which undergoes additional stress testing and lot traceability.
How does the quad-collector configuration affect PCB layout and thermal design?
The four collector terminals (pins 1, 2, 5, 6) must be routed to a common large copper pour-ideally ≥6 cm²-to realize the 113 K/W Rth(j-a) spec. Splitting collectors across separate traces defeats the thermal benefit. The layout should mirror the footprint in Figure 16, with solder paste apertures matching the 0.7 mm × 0.8 mm pads for all six leads.
