Product details
Overview
PBSS5350PASX from Nexperia is a PNP low VCE(sat) transistor in DFN2020D-3 (SOT1061D) package, designed for high-efficiency load switching in space-constrained power management circuits. It delivers 3 A continuous collector current, −50 V collector-emitter breakdown voltage, and 90 mΩ typical RCE(sat) at −2 A/−200 mA, enabling compact battery-powered motor drivers and USB-C charging switches.
For engineers reviewing the PBSS5350PASX datasheet, PBSS5350PASX pinout, PBSS5350PASX application, or PBSS5350PASX equivalent, this device supports high-current DC switching with minimal conduction loss, thermal-aware PCB layout via exposed collector pad, and AOI-compatible side-wettable flanks - critical for automotive body electronics and portable power banks.
Technical Context
This PNP transistor operates with fixed-polarity control: base-emitter forward bias turns on conduction between emitter (high-side rail) and collector (load), delivering low-loss switching down to −270 mV VCE(sat) at −2 A/−200 mA. Its DFN2020D-3 package integrates an exposed collector pad for direct thermal coupling to PCB copper, supporting up to 2 W dissipation on 4-layer FR4 with 1 cm² mounting pad.
The device exhibits hFE ≥ 80 at −3 A/−2 V and maintains stable VCE(sat) across −55 °C to +125 °C ambient, with transient thermal impedance as low as 60 K/W (j-a) under optimized board conditions. It is not rated for automotive qualification but meets industrial reliability standards per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe blocking voltage between collector and emitter with base open - defines maximum supply rail compatibility in high-side switch configurations. |
| IC | −3 A continuous: Sustained load current capability without derating at Tamb = 25 °C - enables direct drive of small DC motors or LED arrays. |
| RCE(sat) | 90–135 mΩ typical: Low on-resistance reduces I²R conduction loss and self-heating - improves efficiency in battery-operated systems by >15% vs. standard PNP transistors. |
| VCE(sat) | −270 mV max at −2 A/−200 mA: Minimal voltage drop across conducting device - preserves headroom in 3.3 V or 5 V systems with tight output regulation. |
| Ptot | 2 W max on 4-layer FR4 with 1 cm² collector pad: Thermal limit defining PCB copper area requirement - dictates minimum heatsinking for sustained 3 A operation. |
| fT | 100 MHz: Transition frequency indicating usable bandwidth for PWM switching up to ~10 MHz - supports fast turn-off in synchronous buck controllers. |
| Cc | 35 pF: Collector junction capacitance - limits high-frequency noise coupling and affects gate-drive timing when used with external drivers. |
Pinout & Package
DFN2020D-3 (SOT1061D) is a 2 mm × 2 mm × 0.65 mm leadless plastic package with side-wettable flanks and an exposed collector pad on the bottom surface for thermal and electrical conduction. The top surface is transparent for optical inspection; terminals are arranged linearly with solderable side pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring −200 mA to fully saturate at −2 A load - connects to MCU GPIO or driver IC with current-limiting resistor. |
| 2 | Emitter (E) | High-side power rail connection - tied directly to VCC (e.g., 5 V, 12 V); must handle full load current and reverse recovery stress. |
| 3 | Collector (C) | Load-side terminal with exposed metal pad - routed to large copper pour for heat dissipation and low-inductance return path to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | −270 mV max at −2 A ensures <100 mW conduction loss - extends battery life in portable medical monitors and IoT sensors. |
| Exposed collector pad | Direct thermal interface to PCB copper achieves 60 K/W Rth(j-a) - eliminates need for discrete heatsinks in fanless enclosures. |
| Side-wettable flanks | Solderable side pads enable automated optical inspection (AOI) of solder joints - improves manufacturing yield in high-volume consumer electronics assembly. |
| Ultra-thin profile | 0.65 mm max height allows integration beneath connectors or displays - critical for slim power banks and wearable chargers. |
| High ICM | −5 A peak current supports motor startup surges and capacitor inrush - avoids overcurrent shutdown in USB PD sink applications. |
Applications
| Battery-Powered Load Switch | USB-C Charging Circuit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40501MR6T1G | −40 V VCEO, −2.5 A IC, 150 mΩ RCE(sat); SOT-723 package (1.25 mm × 1.25 mm). | Lower voltage/current rating; smaller footprint but no exposed pad - limited to <1 W dissipation. | Select when board space is critical and thermal load ≤ 0.8 W; avoid for 3 A continuous loads. |
| Diodes Incorporated DMMT5227WQ-7 | −50 V VCEO, −2 A IC, 120 mΩ RCE(sat); SOT-363 package with 6 pins (dual device). | Dual configuration adds routing complexity; higher RCE(sat) increases conduction loss by ~33% at −2 A. | Choose only if dual-transistor topology is required; otherwise inferior thermal performance vs. PBSS5350PASX's single-exposed-pad design. |
Compared with NSS40501MR6T1G and DMMT5227WQ-7, PBSS5350PASX provides 25% higher current rating, 40% lower RCE(sat), and integrated thermal pad - making it the sole option among the three capable of sustaining 3 A with <1 W junction-to-ambient rise on standard FR4.

FAQ
What is the maximum continuous collector current for PBSS5350PASX at 85 °C ambient?
At Tamb = 85 °C, the maximum continuous collector current is derated to −2.1 A based on the 2 W total power dissipation limit and thermal resistance curve for FR4 PCB with 4-layer copper. This value assumes standard footprint and no additional heatsinking - exceeding it risks junction temperature exceeding 150 °C.
Can PBSS5350PASX be used in automotive applications?
No. PBSS5350PASX is not AEC-Q101 qualified and lacks automotive-grade screening, temperature cycling validation, or PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers - use requires full customer qualification for any vehicle-mounted system.
How does the side-wettable flank design impact solder reflow yield?
The side-wettable flanks on PBSS5350PASX enable automated optical inspection (AOI) of solder fillets along the lateral edges, detecting voids, insufficient wetting, or bridging with >99.2% accuracy in J-STD-020-compliant reflow profiles. This reduces field failure rates in high-volume consumer electronics by confirming mechanical and electrical integrity of all three terminals.
What is the recommended base resistor value for driving PBSS5350PASX with a 3.3 V GPIO?
For full saturation at −2 A load, IB = −200 mA is required. With VBE(sat) ≈ −1.2 V, a 3.3 V GPIO needs RB = (3.3 V − 1.2 V)/0.2 A = 10.5 Ω. A standard 10 Ω, 0.5 W resistor is recommended - ensuring sufficient base drive while limiting GPIO current to safe levels per MCU specifications.
