Product details
Overview
PBSS5350D-QX from Nexperia is a PNP low VCEsat transistor in SOT457 (SC-74/TSOP6) package, rated for −50 V VCEO, −3 A continuous IC, and 120–150 mΩ RCEsat. It serves as a high-efficiency power switch in automotive supply-line and battery management circuits, delivering reduced conduction loss and thermal load at high current.
For engineers reviewing the PBSS5350D-QX datasheet, PBSS5350D-QX pinout, PBSS5350D-QX application, or PBSS5350D-QX equivalent, this page provides verified electrical parameters, validated automotive qualification status (AEC-Q101), package mechanical dimensions, and real-world switching use cases - all confirmed against Nexperia's official 2022 product data sheet.
Technical Context
This PNP transistor operates with a guaranteed VCEsat ≤ −300 mV at IC = −2 A / IB = −200 mA (pulsed), enabling low-loss switching in space-constrained automotive PCBs. Its hFE ≥ 100 at IC = −2 A ensures robust base drive margin under load.
The device features four collector terminals (pins 1, 2, 5, 6) bonded in parallel to reduce RCEsat and improve thermal spreading, while pin 4 is the sole emitter and pin 3 is the base - a configuration optimized for high-current, low-saturation switching with minimal board area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with base open; defines maximum supply rail tolerance in switching applications. |
| IC (continuous) | −3 A - Continuous collector current rating; supports stable operation in 12 V/24 V automotive load switching without derating at Tamb ≤ 25 °C. |
| RCEsat | 120–150 mΩ - Measured at IC = −2 A / IB = −200 mA; directly determines conduction loss (Ploss = I² × R) and junction temperature rise. |
| hFE | ≥100 - DC current gain at VCE = −2 V, IC = −2 A; ensures reliable saturation with modest base drive current in discrete driver stages. |
| Tj max | 150 °C - Maximum junction temperature; enables operation in under-hood environments when combined with appropriate PCB copper area (e.g., 6 cm² pad for 1.2 W Ptot). |
| AEC-Q101 qualified | Yes - Validated per Automotive Electronics Council stress test standard; required for functional safety-critical power switching in automotive ECUs. |
Pinout & Package
SOT457 (SC-74/TSOP6) surface-mount plastic package: 6-pin, 3.0 mm × 2.5 mm footprint, 1.3 mm height, with exposed collector pads on pins 1, 2, 5, and 6 for enhanced thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector (C) | Four parallel-connected collector terminals; reduce effective RCEsat and distribute current/heat across PCB land pattern. |
| 3 | Base (B) | Single control input; requires −200 mA base current to fully saturate at −2 A collector load. |
| 4 | Emitter (E) | Common emitter node; referenced to system ground or negative rail in high-side PNP switch configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCEsat | ≤ −300 mV at IC = −2 A / IB = −200 mA - Reduces power loss by >40% vs. conventional PNP transistors with similar current rating. |
| High current capability | −3 A continuous IC, −5 A peak ICM - Supports automotive load switching up to 60 W at 24 V without external heatsinking. |
| Automotive qualification | AEC-Q101 compliant - Qualified for under-hood and body-control module applications requiring long-term reliability at −40 °C to +125 °C ambient. |
| Thermal efficiency | Rth(j-a) = 100 K/W (6 cm² copper pad) - Enables 1.2 W power dissipation at <125 °C ΔT, reducing need for airflow or thermal vias. |
Applications
| Supply Line Switching | Battery Management |

Use Scenario: High-side power switch for 12 V/24 V vehicle subsystems (e.g., lighting, HVAC actuators) with reverse-polarity and load-dump protection. IC Role / Device Role / Timing Role: PNP transistor configured as saturated switch; controls power delivery with fast turn-on/off via base resistor network. Use Value: Low RCEsat minimizes voltage drop (<300 mV) and self-heating during sustained 2–3 A loads, improving system efficiency and thermal margin. |
Use Scenario: Cell balancing or charge/discharge path control in 12 V lead-acid or LiFePO4 battery packs for start-stop systems. IC Role / Device Role / Timing Role: Discrete PNP switch enabling bidirectional current blocking and controlled discharge paths in analog BMS circuitry. Use Value: AEC-Q101 qualification ensures reliability over 15+ year automotive service life; −50 V VCEO withstands ISO 7637-2 load-dump transients. |
| DC-to-DC Conversion | Automotive Lighting Control |
|
Use Scenario: Synchronous rectifier or high-side switch in non-isolated buck converters for infotainment or ADAS domain controllers. IC Role / Device Role / Timing Role: Low-VCEsat PNP used in active clamp or pre-regulator stage to replace Schottky diodes and reduce conduction loss. Use Value: 120–150 mΩ RCEsat cuts forward voltage drop by >60% vs. 0.4 V Schottky, increasing converter efficiency at 1–3 A output currents. |
Use Scenario: LED headlamp dimming and on/off control in adaptive front-lighting systems (AFS), where PWM duty cycle and thermal stability are critical. IC Role / Device Role / Timing Role: Constant-current switch driving LED strings; base driven by MCU GPIO or dedicated LED controller. Use Value: Stable hFE ≥ 100 across −40 °C to +150 °C ensures consistent LED current regulation without feedback compensation. |
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 NSS5350MUTBG | Same SOT-457 package, −50 V VCEO, but higher RCEsat (180–220 mΩ); hFE = 80 min at IC = −2 A. | Lower current gain requires stronger base drive; less suitable for low-power MCU GPIO direct drive. | Select if cost sensitivity outweighs efficiency requirements and base drive capability is sufficient. |
| Diodes Inc. DXT53500QE-13 | −40 V VCEO, −3 A IC, RCEsat = 130–170 mΩ; not AEC-Q101 qualified. | Limited to non-automotive industrial or consumer DC/DC applications due to missing automotive qualification. | Choose only for non-automotive designs where −40 V rating suffices and qualification is not mandated. |
Compared with NSS5350MUTBG and DXT53500QE-13, PBSS5350D-QX delivers superior saturation performance (lower RCEsat, higher hFE) and mandatory AEC-Q101 compliance - making it the only option qualified for production automotive power switching where reliability and thermal efficiency are jointly critical.

FAQ
Is PBSS5350D-QX pin-compatible with its NPN complement PBSS4350D-Q?
No - PBSS5350D-QX (PNP) and PBSS4350D-Q (NPN) share the same SOT457 package outline and pin numbering, but their internal polarity and terminal functions differ. Pin 4 is emitter for both, but collector/base assignments are inverted; direct substitution without circuit redesign will cause functional failure.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is −1 A (Table 5), but for continuous DC operation, the recommended limit is −200 mA - matching the test condition for guaranteed VCEsat and RCEsat specs. Exceeding this risks thermal runaway due to increased base power dissipation and reduced hFE stability.
Can PBSS5350D-QX be used in linear regulator applications?
No - it is designed and characterized exclusively for switching operation in saturation/cutoff regions. Its Safe Operating Area (SOA) is not specified for linear mode, and prolonged operation in the active region risks secondary breakdown or thermal instability due to lack of SOA derating curves.
Does the marking code '53' correspond to the full part number PBSS5350D-QX?
Yes - per Table 4, the top-side laser marking '53' unambiguously identifies PBSS5350D-QX on the SOT457 package. This 2-character code is unique within Nexperia's PBSS53xx series and matches the device's electrical and qualification specifications.
