Product details
Overview
PBSS5350PAS-QX from Nexperia is a PNP low VCEsat transistor in DFN2020D-3 (SOT1061D) package, rated for −50 V VCEO, −3 A IC, and 90–135 mΩ RCEsat at −2 A/−200 mA drive; used as high-efficiency load switch in automotive power management circuits.
For engineers reviewing the PBSS5350PAS-QX datasheet, PBSS5350PAS-QX pinout, PBSS5350PAS-QX application, or PBSS5350PAS-QX equivalent, this page delivers verified electrical specs, thermal derating curves, AEC-Q101 qualification status, side-wettable flank footprint details, and direct substitution guidance for automotive-grade PNP switching design.
Technical Context
This device operates as a surface-mount PNP bipolar junction transistor with optimized saturation characteristics: VCEsat ≤ −390 mV at −3 A/−300 mA drive and RCEsat = 90–135 mΩ under pulsed conditions (tp ≤ 300 µs, δ ≤ 0.02). Its DFN2020D-3 package integrates exposed collector pad for thermal conduction and side-wettable flanks for AOI-compatible solder joint inspection.
Qualified per AEC-Q101, it supports ambient temperatures from −65 °C to 150 °C and junction temperatures up to 150 °C. Thermal resistance Rth(j-a) ranges from 60 K/W (4-layer FR4 + 1 cm² collector pad) to 250 K/W (standard single-sided FR4), enabling precise thermal budgeting in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum allowable collector-emitter voltage with base open; defines safe blocking capability in high-side switch configurations. |
| IC | −3 A - Continuous DC collector current rating; supports sustained load switching in battery-powered motor/fan drivers. |
| RCEsat | 90–135 mΩ - Low-saturation resistance at −2 A/−200 mA; reduces conduction loss and self-heating in compact PCB layouts. |
| VCEsat | ≤ −390 mV - Measured at −3 A/−300 mA pulsed; enables <1 W dissipation at full rated current under typical automotive pulse conditions. |
| fT | 100 MHz - Transition frequency at −5 V VCE, −100 mA IC; sufficient for PWM switching up to ~10 MHz with stable gain margin. |
| hFE | 80 min - DC current gain at −2 V VCE, −3 A IC; ensures reliable saturation with moderate base drive in cost-sensitive designs. |
| Cc | 35 pF - Collector capacitance at −10 V VCB; limits high-frequency switching losses and EMI generation in fast-switching loads. |
Pinout & Package
DFN2020D-3 (SOT1061D) is a 2 mm × 2 mm × 0.65 mm leadless thermally enhanced package with side-wettable flanks and an exposed collector pad on the bottom for optimal heat transfer and AOI compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input terminal; requires −200 mA to −300 mA drive for full saturation at −2 A to −3 A collector current. |
| 2 | Emitter (E) | Current source node; connected to higher potential rail (e.g., battery +) in high-side switch topology. |
| 3 | Collector (C) | Switched output node; electrically and thermally tied to exposed bottom pad for low-inductance, high-current path and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin applications per stress test standard; supports PPAP documentation requirements. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray; improves manufacturing yield in SMT lines. |
| Exposed collector pad | Provides direct thermal path to PCB copper; achieves Rth(j-a) as low as 60 K/W with 4-layer board and 1 cm² pad. |
| Low RCEsat (90 mΩ typ.) | Reduces I²R conduction loss by >40% vs. standard PNP transistors; extends battery runtime in portable automotive accessories. |
| Ultra-thin profile (0.65 mm max) | Enables stacking in multi-layer modules and integration into tight mechanical envelopes such as door control units or seat controllers. |
Applications
| Automotive Load Switch | Battery Protection Circuit |
|---|---|
|
Use Scenario: High-side power switch controlling 12 V accessory loads (e.g., HVAC blower, window lift motor) in vehicle body control modules. IC Role / Device Role / Timing Role: PNP transistor configured as saturated switch; turns on/off load current under MCU GPIO control via base resistor network. Use Value: Low VCEsat minimizes voltage drop and heat generation during continuous 3 A operation, eliminating need for external heatsink in plastic enclosures. |
Use Scenario: Reverse-polarity and overcurrent protection in 12 V/24 V battery-fed infotainment head units and telematics gateways. IC Role / Device Role / Timing Role: PNP pass element in active crowbar or foldback current limiter; responds within microseconds to fault conditions. Use Value: Fast turn-off capability (driven by hFE ≥ 80) and robust VCEO rating ensure reliable shutdown before fuse interruption or system damage. |
| USB-C Power Delivery Switch | Charging Path Management |
|
Use Scenario: Input power path selection between wall adapter and car charger in portable diagnostic tools and OBD-II dongles. IC Role / Device Role / Timing Role: Bidirectional load switch controlled by PMIC enable signal; handles up to 3 A charging current with minimal forward drop. Use Value: RCEsat ≤ 135 mΩ ensures <400 mV total drop at 3 A, preserving USB PD voltage compliance and reducing thermal stress on PCB traces. |
Use Scenario: Smart battery charging circuit managing dual Li-ion cells in automotive jump starters and portable power banks. IC Role / Device Role / Timing Role: PNP switch isolating charging IC from battery during standby; blocks leakage current with ICES ≤ 100 nA. Use Value: Ultra-low cutoff current and −5 V VEBO rating prevent unintended discharge and support reverse-battery-safe operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-VCEsat switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS5350PDS | Same VCEO (−50 V), but higher RCEsat (150–220 mΩ); DFN2020D-3 package with identical pinout. | Lower efficiency at high current; requires larger thermal pad or lower ambient to maintain Tj < 150 °C. | Select when cost sensitivity outweighs thermal performance; verify base drive compatibility due to hFE = 60 min. |
| Diodes Incorporated DMMT5350WQ-7 | −50 V VCEO, −3 A IC, but VCEsat = −500 mV typ. at −3 A; same DFN2020D-3 footprint and AEC-Q101 qualified. | Higher conduction loss increases board temperature rise by ~15 °C at 3 A continuous; less suitable for sealed enclosures. | Prefer for legacy designs where layout reuse is critical and thermal margin exists; avoid in fanless or high-ambient environments. |
Compared with NSS5350PDS and DMMT5350WQ-7, PBSS5350PAS-QX delivers lowest RCEsat and highest hFE, enabling smaller base drive networks, reduced PCB copper area, and extended thermal headroom in automotive power switches.

FAQ
What is the maximum continuous collector current for PBSS5350PAS-QX at 100 °C ambient?
At Tamb = 100 °C, the maximum continuous IC is derated to approximately −1.8 A based on Fig. 1 power derating curve for standard FR4 mounting (Rth(j-a) = 250 K/W). This assumes no additional copper area beyond the standard footprint and maintains Tj ≤ 150 °C.
Does PBSS5350PAS-QX support reflow soldering with standard lead-free profiles?
Yes - the DFN2020D-3 package is qualified for lead-free reflow per J-STD-020. Recommended peak temperature is 260 °C for ≤ 30 seconds; Fig. 17 provides exact stencil and land pattern dimensions for reliable side-wettable flank wetting and void-free solder joints.
How does the exposed collector pad affect PCB layout requirements?
The exposed collector pad must be connected to a dedicated thermal copper pour (minimum 1 cm² for 60 K/W Rth(j-a)). Vias under the pad are recommended for 4-layer boards; solder mask defined pads improve solder flow. Avoid routing signals under the pad to prevent coupling and thermal interference.
Is PBSS5350PAS-QX suitable for linear regulator applications?
No - it is optimized for saturated switching, not linear operation. Its low RCEsat and high fT do not compensate for limited Safe Operating Area (SOA) in linear mode; use only in switching configurations with adequate base drive and transient protection per datasheet Fig. 9 and Fig. 12.
