Product details

Overview

PBSS5330PAS-QX from Nexperia is a PNP low V_CE(sat) transistor in a DFN2020D-3 (SOT1061D) ultra-thin leadless package, rated for −30 V V_CEO, −3 A continuous collector current, and 75 mΩ typical R_CE(sat) at −3 A/−300 mA drive. It serves as a high-efficiency load switch in automotive power management circuits operating up to 175 °C junction temperature.

For engineers reviewing the PBSS5330PAS-QX datasheet, PBSS5330PAS-QX pinout, PBSS5330PAS-QX application, or PBSS5330PAS-QX equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for AOI-compatible solder joint inspection, and thermal performance on FR4 versus ceramic PCBs under pulsed and DC conditions.

Technical Context

This PNP bipolar transistor uses optimized epitaxial base and emitter structures to achieve low saturation voltage while maintaining high h_FE (100–160 at −3 A) and fast switching (t_on = 70 ns, t_off = 200 ns). Its DFN2020D-3 package integrates an exposed collector pad for direct thermal conduction and electrical grounding.

The device operates with V_BE(sat) = −0.97 V typical at −3 A/−300 mA and supports pulse operation up to −5 A (tp ≤ 1 ms), with thermal resistance as low as 60 K/W when mounted on a 4-layer FR4 PCB with 1 cm² collector pad.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−30 V - Maximum safe collector-emitter blocking voltage with base open; defines off-state voltage headroom in high-side switch configurations.
I_C	−3 A - Continuous DC collector current rating; supports sustained load switching in battery-powered automotive modules.
R_CE(sat)	75 mΩ typ - Low saturation resistance reduces conduction loss and self-heating during active switching, enabling compact thermal design.
h_FE	100–160 at −3 A - High DC current gain ensures robust drive margin with modest base current (−300 mA), simplifying driver stage design.
T_j(max)	175 °C - Junction temperature limit validated per AEC-Q101; enables deployment in under-hood automotive environments without derating.
t_off	200 ns - Fast turn-off time supports high-frequency PWM control in motor drivers and LED dimming applications.
V_CE(sat)	−230 mV typ at −3 A/−300 mA - Ultra-low saturation voltage minimizes power dissipation (P = I² × R) in high-current switching paths.

Pinout & Package

Encapsulated in the DFN2020D-3 (SOT1061D) ultra-thin leadless package (2.0 mm × 2.0 mm × 0.65 mm), this device features side-wettable flanks for automated optical inspection and an exposed collector pad for enhanced thermal and electrical performance.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal accepting negative current to forward-bias the base-emitter junction; requires −300 mA for full saturation at −3 A load.
2	Emitter (E)	Current source node tied to system supply rail in high-side switch topology; carries full load current and defines reference potential.
3	Collector (C)	Output terminal connected to load; electrically and thermally coupled to exposed copper pad for low-impedance path to PCB ground plane.

Key Features

Feature	Design Value
Low V_CE(sat)	−230 mV typical at −3 A ensures <1 W conduction loss, reducing heatsink requirements in space-constrained modules.
AEC-Q101 qualified	Validated for automotive use including temperature cycling, HTRB, and ESD testing-enables drop-in use in ASIL-B supporting systems.
Side-wettable flanks	Enables 100% automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield and field reliability.
Exposed collector pad	Provides <60 K/W thermal resistance to ambient on optimized 4-layer FR4, allowing >2.5 W power dissipation without external heatsink.
High-temperature operation	Rated for continuous operation at T_amb = 175 °C, supporting placement near power converters or engine control units.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP low V_CE(sat) transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS40201LT1G	−20 V V_CEO, −2 A I_C, −150 mV V_CE(sat) typ - lower voltage/current rating and higher saturation voltage.	Not AEC-Q101 qualified; limited to non-automotive industrial or consumer power switches.	Select only if system voltage remains ≤16 V and thermal budget allows +70 mV extra V_CE(sat) loss.
Diodes Incorporated DMMT3906-7-F	−40 V V_CEO, −200 mA I_C, −400 mV V_CE(sat) - significantly lower current capability and higher saturation voltage.	Suitable for signal-level switching only; cannot replace PBSS5330PAS-QX in ≥1 A load applications.	Use only for biasing or logic-level translation where current is <100 mA and voltage headroom exceeds 30 V.

Compared with NSS40201LT1G and DMMT3906-7-F, PBSS5330PAS-QX delivers 50% higher current handling, 60% lower R_CE(sat), and automotive-grade qualification-making it the sole option for AEC-compliant 3 A load switching at 12–24 V.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum base current is −500 mA per datasheet limiting values. However, for reliable continuous operation at −3 A collector current, the recommended base drive is −300 mA (IC/IB = 10), ensuring saturation without excessive base power dissipation or thermal stress on the bond wires.

Can PBSS5330PAS-QX be used in a high-side switch configuration with 24 V supply?

Yes. With −30 V V_CEO rating and −3 A continuous current capability, PBSS5330PAS-QX is fully rated for 24 V high-side switching. Its −230 mV V_CE(sat) ensures minimal voltage drop and power loss (<0.7 W) at full load, even at elevated ambient temperatures up to 125 °C.

Does the DFN2020D-3 package support reflow soldering per JEDEC J-STD-020?

Yes. The DFN2020D-3 (SOT1061D) package is qualified for standard lead-free reflow profiles per JEDEC J-STD-020D, with peak temperature up to 260 °C. The side-wettable flanks and thermal pad design enable consistent solder joint formation and AOI compatibility without requiring specialized stencil or profile adjustments.

How does thermal performance differ between FR4 and ceramic PCB mounting?

On a standard FR4 PCB, R_th(j-a) is 250 K/W; with a 1 cm² collector pad on 4-layer FR4, it improves to 60 K/W. On Al₂O₃ ceramic, R_th(j-a) reaches 60 K/W even with standard footprint-enabling 2.5 W dissipation at T_amb = 75 °C without forced air cooling in either case.
