Product details
Overview
PBSS4630PA from Nexperia is an NPN low VCE(sat) Breakthrough In Small Signal (BISS) transistor in a leadless SOT1061 (HUSON3) package, rated for 30 V VCEO, 6 A continuous collector current, and 35–46 mΩ RCE(sat) at IC = 6 A / IB = 300 mA. It serves as a high-efficiency load switch in battery-powered power management circuits with minimal PCB footprint.
For engineers reviewing the PBSS4630PA datasheet, PBSS4630PA pinout, PBSS4630PA application, or PBSS4630PA equivalent, this device is selected for low-loss switching in compact DC-DC converters, motor drivers, and USB-C power delivery paths where thermal performance under medium-power loads is critical.
Technical Context
This BISS transistor uses a proprietary epitaxial structure to achieve ultra-low saturation resistance while maintaining robust switching speed: ton = 80 ns and toff = 570 ns at VCC = 9 V, IC = 2 A. Its exposed collector pad enables direct thermal coupling to PCB copper, supporting up to 2.1 W dissipation on ceramic substrates.
The device operates across −55 °C to +150 °C ambient, with hFE ranging from 180–280 at IC = 6 A and VCE = 2 V. It features low leakage: ICBO ≤ 100 nA at 24 V and 25 °C, and exhibits fT = 70–115 MHz, confirming suitability for high-speed digital switching-not RF amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in 24 V systems. |
| IC | 6 A - Continuous DC collector current rating; supports sustained 5–6 A load switching without forced cooling. |
| RCE(sat) | 35–46 mΩ - Measured at IC = 6 A / IB = 300 mA; yields ≤275 mV VCE(sat), minimizing conduction loss in power paths. |
| fT | 70–115 MHz - Transition frequency at VCE = 10 V, IC = 100 mA; confirms fast switching capability for PWM frequencies up to ~10 MHz. |
| Rth(j-a) | 60–250 K/W - Junction-to-ambient thermal resistance; drops to 60 K/W with 1 cm² collector pad on ceramic PCB, enabling >1.5 W operation. |
| hFE | 180–280 - DC current gain at IC = 6 A / VCE = 2 V; ensures reliable saturation with modest 300 mA base drive. |
| toff | 570 ns - Turn-off time at VCC = 9 V, IC = 2 A; limits minimum off-time in high-frequency synchronous buck controllers. |
Pinout & Package
Package: SOT1061 (HUSON3), ultra-thin 2.0 × 2.0 × 0.65 mm leadless plastic package with exposed collector thermal pad. Dimensions comply with JEDEC MO-252.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring ~300 mA drive for full saturation; connected to MCU GPIO or driver IC output. |
| 2 | Emiter | Reference node tied to system ground; forms low-impedance return path for load current. |
| 3 | Collector | Power output terminal with exposed metal pad; must be soldered to ≥1 cm² copper pour for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RCE(sat) | 35–46 mΩ at 6 A enables <150 mW conduction loss in 5 A loads-critical for portable device battery life. |
| Thermally enhanced SOT1061 | Exposed collector pad reduces Rth(j-a) to 60 K/W on ceramic PCB, allowing 2.1 W dissipation without heatsink. |
| High IC/ICM capability | 6 A continuous / 7 A pulsed rating supports fan, LED string, and small motor drives in space-constrained designs. |
| Fast switching | 80 ns ton and 570 ns toff support PWM frequencies >100 kHz, reducing output filter size in DC-DC stages. |
| Wide temperature range | −55 °C to +150 °C operation ensures reliability in automotive cabin modules and industrial controllers. |
Applications
| Load Switching | Battery Protection Circuit |
|---|---|
Use Scenario: High-side power control for USB-C PD sink port, enabling/disabling 5–20 V input rails. IC Role / Device Role / Timing Role: NPN BISS transistor configured as low-side switch driving gate of external high-side MOSFET or directly switching load. Use Value: 35 mΩ RCE(sat) limits voltage drop to <210 mV at 6 A, preserving input regulation margin and reducing self-heating. |
Use Scenario: Overcurrent cutoff in lithium-ion battery pack protection IC auxiliary path during charge termination. IC Role / Device Role / Timing Role: Fast-acting current limiter activated by protection IC's fault signal to disconnect charging FET gate drive. Use Value: 570 ns toff ensures sub-microsecond response to overcurrent events, preventing cell damage during transient faults. |
| DC-DC Converter Sync Rectifier | Fan/Motor Driver Stage |
Use Scenario: Secondary-side synchronous rectification in isolated flyback converter for 12 V/3 A industrial SMPS. IC Role / Device Role / Timing Role: Low-VCE(sat) switch replacing Schottky diode to reduce conduction loss and improve efficiency above 75% load. Use Value: 275 mV max VCE(sat) at 6 A cuts forward drop by >40% vs. typical 0.45 V Schottky, boosting full-load efficiency by ~1.2%. |
Use Scenario: PWM-controlled 24 V brushed DC fan driver in network equipment chassis cooling system. IC Role / Device Role / Timing Role: Medium-power switching element driven by microcontroller PWM output to regulate fan speed. Use Value: 6 A IC rating handles 5 A stall current of 120 mm fans; exposed pad maintains Tj < 125 °C at 100% duty cycle. |
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 |
|---|---|---|---|
| DMT3006LPSQ-13 | 60 V VCEO, 3.5 A IC, 45 mΩ RDS(on) (MOSFET); requires gate drive >4.5 V. | Higher voltage margin but lower current; suited for 48 V systems where gate drive voltage is stable. | Select when higher breakdown voltage is required and gate drive exceeds 4.5 V; avoid if base drive is limited to 3.3 V logic. |
| PBSS4041PAS,115 | 40 V VCEO, 4.1 A IC, 50 mΩ RCE(sat); same SOT1061 package and pinout. | Lower current and higher saturation resistance; suitable for <4 A loads with tighter voltage headroom. | Drop-in replacement only for derated applications; verify thermal margin at 4 A due to +15 mΩ RCE(sat) increase. |
Compared with PBSS4630PA, DMT3006LPSQ-13 offers higher voltage tolerance but demands higher gate voltage and lacks bipolar simplicity, while PBSS4041PAS,115 provides identical form factor with reduced current capability-making PBSS4630PA optimal for 6 A, 30 V load-switching where minimal VCE(sat) and 3.3 V–5 V base drive compatibility are essential.

FAQ
What is the maximum continuous collector current for PBSS4630PA?
The PBSS4630PA is rated for 6 A continuous collector current (IC) at Tamb ≤ 25 °C with appropriate PCB copper area. Derating applies above 25 °C: at 100 °C ambient, maximum IC drops to ~4.2 A based on thermal resistance curves and 150 °C junction limit.
Can PBSS4630PA be used in high-frequency PWM applications?
Yes-its 70–115 MHz fT and 570 ns toff support PWM frequencies up to 500 kHz with acceptable switching losses. For >1 MHz operation, verify gate/base drive strength and layout parasitics, as stored charge effects may increase turn-off delay.
What PCB layout practices maximize thermal performance?
Connect Pin 3 (collector) to ≥1 cm² of 2 oz copper on inner or outer layer, using multiple thermal vias to internal ground planes. Avoid solder mask over the exposed pad. Use reflow profile per Nexperia SOT1061 guidelines to ensure void-free solder joint for optimal thermal transfer.
Is PBSS4630PA automotive qualified?
No-PBSS4630PA is not AEC-Q101 qualified. It is specified for industrial and consumer applications. For automotive use, Nexperia offers the AEC-Q101-qualified PBSS4630PAS variant; consult official Nexperia documentation before deployment in vehicle systems.
