Product details
Overview
PBSS5350Z-QF from Nexperia is a PNP low VCE(sat) transistor in SOT223 (SC-73) package, designed for high-efficiency switching in automotive and industrial power control circuits. It delivers 50 V VCEO, −3 A continuous collector current, 120–150 mΩ RCE(sat) at −2 A/−200 mA drive, and is AEC-Q101 qualified for under-hood applications including LED backlighting and DC/DC converter switches.
For engineers reviewing the PBSS5350Z-QF datasheet, PBSS5350Z-QF pinout, PBSS5350Z-QF application, or PBSS5350Z-QF equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade thermal performance, and real-world substitution guidance - all grounded in Nexperia's official 2022 product data sheet.
Technical Context
This PNP bipolar junction transistor operates with a low saturation voltage optimized for minimal conduction loss in medium-power switching. Its high hFE (>200 at −500 mA) and robust peak current capability (−5 A, tp ≤ 1 ms) support reliable base-driven switching across wide temperature ranges (−65 °C to +150 °C).
The device features dual collector terminals (Pins 2 & 4) in its 4-pin SOT223 package to enhance thermal dissipation and current handling. Thermal resistance from junction to ambient is as low as 62.5 K/W when mounted on a 6 cm² copper pad - enabling stable operation without heatsinks in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter blocking voltage in open-base configuration; enables use in 24 V automotive systems with margin. |
| IC | −3 A continuous: Sustained collector current rating at Tamb = 25 °C; supports high-current load switching without derating in moderate ambient. |
| RCE(sat) | 120–150 mΩ at IC = −2 A, IB = −200 mA: Low on-resistance reduces power loss and self-heating during active conduction. |
| hFE | ≥100 at IC = −2 A: High DC current gain ensures efficient base drive utilization and simplifies driver circuit design. |
| Ptot | 2 W with 6 cm² copper pad: Total power dissipation limit under optimized PCB layout; defines maximum steady-state thermal envelope. |
| Tj max | +150 °C: Maximum allowable junction temperature; aligns with AEC-Q101 stress test requirements for automotive reliability. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads, 2.3 mm pitch, and integrated heatsink tab (Pin 3 = emitter, Pins 2 & 4 = collector, Pin 1 = base). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; mounting pad recommended for collector terminals to maximize thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires −200 mA drive for full saturation at −2 A collector current. |
| 2 | Collector | Main high-side current path; electrically tied to Pin 4 for parallel current sharing and improved thermal conduction. |
| 3 | Emiter | Reference and return node; connected to system ground or supply rail depending on PNP high-side switch topology. |
| 4 | Collector | Second collector terminal; shares internal die connection with Pin 2 to reduce effective RDS(on)-like resistance and improve heat spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | ≤300 mV at IC = −2 A, IB = −200 mA: Minimizes conduction loss and improves efficiency in battery-powered and thermally constrained systems. |
| AEC-Q101 qualification | Qualified per Stress Test Qualification for Discrete Semiconductors: Enables direct use in automotive powertrain, body electronics, and ADAS subsystems without additional qualification effort. |
| Dual-collector thermal design | Pins 2 & 4 both connect to collector region: Doubles current-carrying capacity per lead and lowers effective thermal resistance to PCB copper. |
| High hFE at high IC | ≥100 at IC = −2 A: Reduces required base drive current, easing microcontroller GPIO or small-driver IC loading in compact designs. |
Applications
| DC/DC Converter Switch | Battery Charger Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-saturation transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40501MZ4T1G | −40 V VCEO, −2.5 A IC, 190 mΩ RCE(sat); SOT-223, no dual-collector pins | Limited to 12 V systems; lower peak current and higher saturation resistance reduce efficiency in 24 V loads | Select when cost sensitivity outweighs thermal performance and automotive qualification is not required. |
| Diodes Incorporated DXT53500QE-13 | −50 V VCEO, −3 A IC, 140 mΩ RCE(sat); AEC-Q101 qualified, single-collector SOT223 | Matches voltage/current specs but lacks dual-collector thermal advantage; slightly higher RCE(sat) at high IC | Prefer for drop-in replacement where PCB footprint compatibility is critical and thermal margin is sufficient. |
Compared with NSS40501MZ4T1G and DXT53500QE-13, PBSS5350Z-QF delivers superior thermal performance via dual-collector construction and tighter RCE(sat) tolerance - making it optimal for sustained 2 A+ switching in automotive modules where board area and heatsinking are constrained.

FAQ
Is PBSS5350Z-QF pin-compatible with standard SOT223 PNP transistors?
Yes - PBSS5350Z-QF uses the industry-standard SC-73 (SOT223) outline with 2.3 mm lead pitch and identical mechanical footprint. Pins 1 (base), 2 (collector), and 3 (emitter) match conventional SOT223 pinning; Pin 4 is an additional collector terminal that may be left unconnected or tied to Pin 2 in legacy layouts.
What is the maximum safe operating temperature for PBSS5350Z-QF in continuous conduction mode?
The absolute maximum junction temperature is +150 °C. Under continuous −2 A operation with a 6 cm² copper pad, thermal resistance drops to 62.5 K/W, allowing ambient temperatures up to +87.5 °C before reaching Tj = 150 °C - verified per Nexperia's Figure 1 derating curves.
Does PBSS5350Z-QF require a base resistor when driven by a 3.3 V microcontroller GPIO?
Yes - with VBE(sat) ≈ −1.2 V and required IB = −200 mA for full saturation at −2 A, a 10 Ω series resistor is typical to limit GPIO current while ensuring reliable turn-on; exact value depends on MCU output capability and desired switching speed.
How does the dual-collector configuration affect PCB layout and thermal design?
The dual-collector (Pins 2 & 4) must be routed to the same copper pour or thermal pad to realize the full 62.5 K/W Rth(j-a) benefit. Splitting them or routing separately negates the thermal advantage and risks current imbalance; Nexperia's recommended footprint (Figure 13) specifies shared solder land geometry.
