Product details
Overview
PBSS302ND-QH from Nexperia is an AEC-Q101-qualified NPN low VCEsat transistor in TSOP6 (SOT457) package, designed for high-efficiency switching in automotive power management. It delivers 4 A continuous collector current, 40 V VCEO, and ultra-low 55–75 mΩ RCEsat at 6 A/600 mA drive - enabling reduced conduction loss in DC-DC converters and MOSFET gate drivers.
For engineers reviewing the PBSS302ND-QH datasheet, PBSS302ND-QH pinout, PBSS302ND-QH application, or PBSS302ND-QH equivalent, this device is selected for thermally constrained automotive subsystems requiring stable low-saturation switching with validated junction temperature up to 150 °C and pulsed peak current capability of 15 A.
Technical Context
This NPN transistor operates as a high-current, low-loss switch with fixed polarity and no integrated biasing or protection circuitry. Its design centers on minimizing VCEsat and RCEsat under high IC/IB conditions (IC/IB = 10–20), supported by thermal resistance as low as 113 K/W on 6 cm² FR4 copper pad.
Switching performance is characterized by 64 ns turn-on time and 510 ns turn-off time under 10 V VCC, 2 A IC, ±0.1 A base drive - optimized for medium-frequency (<1 MHz) power control where propagation delay and storage time (390 ns) impact efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum allowable collector-emitter voltage with base open; defines safe blocking capability in 12 V/24 V automotive systems. |
| IC (continuous) | 4 A - Sustained collector current at Tamb ≤ 25 °C on ceramic PCB; enables direct driving of small motors or backlight inverters without heatsinking. |
| RCEsat | 55–75 mΩ - Measured at IC = 6 A, IB = 600 mA, pulsed; determines I²R conduction loss and thermal rise in high-duty-cycle operation. |
| VCEsat | 330–450 mV - Saturation voltage at IC = 4 A, IB = 400 mA; directly sets minimum on-state voltage drop and associated power dissipation. |
| hFE | 50–100 - DC current gain at IC = 6 A, VCE = 2 V; informs required base drive strength and driver stage sizing. |
| fT | 150 MHz - Transition frequency at VCE = 10 V, IC = 0.1 A; indicates usable bandwidth for fast-switching applications up to ~10–20 MHz. |
| toff | 510 ns - Total turn-off time under defined test conditions; constrains maximum practical switching frequency before losses dominate. |
Pinout & Package
TSOP6 (SOT457) surface-mount plastic package with 6 leads, 1.3 mm profile, and standard footprint compatible with reflow soldering per IPC-7095. Thermal pad layout supports 6 cm² copper area for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Collector | Primary high-current output node; internally connected to pins 2, 5, and 6 for parallel current handling and improved thermal spreading. |
| 2 | Collector | Redundant collector terminal - electrically identical to pin 1; used to reduce bond wire inductance and improve current sharing. |
| 3 | Base | Control input requiring ~400 mA drive at 4 A IC; low-impedance path optimized for fast switching with minimal Miller effect. |
| 4 | Emiter | Reference node for emitter-follower or common-emitter configurations; isolated from collector terminals to prevent latch-up in inductive loads. |
| 5 | Collector | Third collector connection - enhances thermal conductivity and reduces effective Rth(j-sp) to 45 K/W to solder point. |
| 6 | Collector | Fourth collector terminal - provides mechanical stability and additional current-carrying capacity in high-reliability automotive layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RCEsat | 55 mΩ typical at 6 A - reduces conduction loss by >40% vs. standard bipolar transistors, lowering thermal load in space-constrained modules. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD - enables use in engine control, body electronics, and ADAS power stages. |
| Multi-collector pin architecture | Four collector terminals (pins 1, 2, 5, 6) - lowers effective package inductance and improves current distribution, critical for EMI-sensitive motor drives. |
| High peak current rating | 15 A single-pulse (tp ≤ 1 ms) - supports surge handling in fan startup, solenoid actuation, and transient load conditions without derating. |
| Low VBEsat | 1.0 V max at IC = 4 A - minimizes base drive power and allows compatibility with 3.3 V or 5 V logic-level controllers without level-shifting. |
Applications
| Automotive DC-DC Converters | MOSFET Gate Driving |
|---|---|
|
Use Scenario: Step-down conversion in 12 V to 5 V/3.3 V power rails for infotainment and ADAS ECUs. IC Role / Device Role / Timing Role: Primary switching transistor in synchronous buck topology, operating at 200–500 kHz with forced PWM mode. Use Value: 330 mV VCEsat limits conduction loss to <1.3 W at 4 A, reducing thermal design burden versus higher-VCEsat alternatives. |
Use Scenario: High-side or low-side gate driver for 40 V-rated N-channel MOSFETs in battery disconnect and load switching. IC Role / Device Role / Timing Role: Current-amplifying switch delivering ≥400 mA peak base/gate current with <64 ns turn-on for fast MOSFET transition.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low VCEsat transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS30201MR6T1G | Higher VCEO (60 V), lower IC (2 A), RCEsat = 90 mΩ @ 2 A - less efficient at 4 A load. | Preferred in 48 V mild-hybrid systems; unsuitable for 4 A continuous automotive motor loads. | Select when higher voltage margin is needed over current capability; verify thermal design for same PCB area. |
| Diodes Incorporated DXTN3020P5-13 | Same SOT457 package, but RCEsat = 105 mΩ @ 4 A and no AEC-Q101 qualification - higher conduction loss and unverified automotive reliability. | Acceptable for industrial non-automotive DC-DC; not approved for automotive safety-critical functions. | Use only in cost-sensitive non-automotive designs; avoid where AEC-Q101 compliance is contractually required. |
Compared with NSS30201MR6T1G and DXTN3020P5-13, PBSS302ND-QH uniquely balances 4 A continuous rating, 55 mΩ RCEsat, and AEC-Q101 qualification - making it the only option among the three qualified for sustained 12 V automotive power switching with thermal margin on standard FR4.

FAQ
What is the maximum allowable junction temperature for PBSS302ND-QH?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in the limiting values table. Operation at this temperature requires strict adherence to thermal derating curves - for example, total power dissipation must be limited to 500 mW on standard FR4 at 100 °C ambient to maintain safe Tj.
Can PBSS302ND-QH replace a MOSFET in low-side switching applications?
No - PBSS302ND-QH is a bipolar NPN transistor requiring continuous base current drive, unlike MOSFETs that use voltage-controlled gates. While it can perform low-side switching, its 400 mA base drive demand and 330 mV VCEsat make it less efficient than logic-level MOSFETs above 1 A; it excels where bipolar characteristics (e.g., ruggedness, SOA, cost) are prioritized.
Is the TSOP6 (SOT457) package lead-free and RoHS compliant?
Yes - PBSS302ND-QH uses a lead-free, halogen-free, RoHS-compliant TSOP6 package per Nexperia's product compliance documentation. The device meets JEDEC J-STD-020 moisture sensitivity level MSL3 and is qualified for standard reflow profiles including peak temperatures up to 260 °C.
How does the multi-collector pin configuration affect PCB layout?
The four collector pins (1, 2, 5, 6) must be routed to a common copper pour with ≥6 cm² area for optimal thermal performance. Splitting or isolating these pins increases Rth(j-a) by up to 2× and risks current imbalance - Nexperia's recommended footprint uses a single large thermal pad connected to all four collector lands.
