Product details
Overview
PDTC143XQA from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a leadless DFN1010D-3 (SOT1215) package with integrated 4.7 kΩ input bias resistor (R1) and 10 kΩ pull-down resistor (R2), designed for digital switching applications including IC input control and load switching in space-constrained automotive and industrial systems.
For engineers reviewing the PDTC143XQA datasheet, PDTC143XQA pinout, PDTC143XQA application, or PDTC143XQA equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, exact pin functions, and validated alternative parts for direct design-in evaluation.
Technical Context
The PDTC143XQA integrates a monolithic NPN transistor with two on-die silicon resistors-R1 connected between base and input terminal, R2 between base and emitter-enabling single-pin drive operation without external bias components. Its internal structure eliminates need for discrete base resistors while maintaining full control over saturation behavior.
It operates as a digital switch with guaranteed VI(on) ≤ 1.5 V at IC = 20 mA and VI(off) ≥ 0.8 V at IC = 100 µA, supporting TTL/CMOS logic-level interfacing. The device is qualified to AEC-Q101 and rated for ambient temperatures from −55 °C to +150 °C, with junction temperature up to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | 100 mA - Continuous DC output current capability; sufficient for driving LEDs, relays, and logic inputs. |
| R1 | 4.7 kΩ - Integrated input bias resistor; sets base current for predictable turn-on with standard logic drivers. |
| R2/R1 ratio | 2.1 - Optimized resistor ratio ensures stable saturation and fast turn-off by actively pulling base low. |
| VCE(sat) | ≤ 100 mV at IC = 10 mA, IB = 0.5 mA - Ultra-low saturation voltage minimizes power loss in high-duty-cycle switching. |
| fT | 230 MHz - Transition frequency of internal transistor; enables reliable operation beyond typical digital switching frequencies. |
| Ptot | 280 mW (FR4, 1-layer) - Total power dissipation limit; defines thermal boundary for PCB layout and airflow planning. |
Pinout & Package
Package: DFN1010D-3 (SOT1215), ultra-thin 1.1 × 1.0 × 0.37 mm surface-mount plastic package with visible and solderable side pads; thermally enhanced for improved heat transfer via exposed pad (pin 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Driven directly by logic signal; connects internally to R1 and transistor base. |
| 2 | GND (emitter) | Emitter terminal and thermal pad; must be soldered to PCB ground plane for thermal and electrical performance. |
| 3 | Output (collector) | Switched high-side output node; connects to load and supply rail. |
| 4 | Output (collector) | Second collector terminal-electrically tied to pin 3; doubles current-carrying capacity and improves thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-suitable for under-hood and ADAS modules. |
| 0.37 mm package height | Enables use in ultra-thin consumer electronics and wearable devices where Z-height is constrained. |
| Solderable side pads | Supports automated optical inspection (AOI) of solder joints and improves reflow yield on fine-pitch PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC123JQA | R1 = 2.2 kΩ, R2 = 47 kΩ; higher R2/R1 ratio (21) yields stronger base pull-down but lower input sensitivity. | Better noise immunity in electrically noisy PLC environments; less suitable for weak-drive microcontrollers. | Select when VI(off) margin > 0.6 V is required and drive strength exceeds 0.25 mA. |
| BC847B, SOT23 | Discrete NPN BJT without built-in resistors; requires two external 10 kΩ resistors for equivalent biasing. | Higher board area, additional placement cost, and no AEC-Q101 qualification out-of-box. | Choose only if legacy design reuse mandates SOT23 footprint or if custom R1/R2 values are needed. |
Compared with PDTC123JQA, PDTC143XQA offers higher input sensitivity (VI(on) = 1.5 V vs. 0.75 V) and lower R1 for stronger base drive, while BC847B demands external biasing and lacks automotive qualification-making PDTC143XQA optimal for new compact, qualified designs.

FAQ
What is the maximum operating temperature for PDTC143XQA?
The PDTC143XQA has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance Rth(j-a) is 446 K/W on a single-layer FR4 PCB, meaning power dissipation must be limited to maintain safe junction temperature under worst-case ambient conditions. Derating curves in the datasheet guide thermal design for continuous operation.
Is PDTC143XQA pin-compatible with other RETs in the PDTC143X/123J/143Z/114YQA series?
Yes, all variants-including PDTC143XQA, PDTC123JQA, PDTC143ZQA, and PDTC114YQA-share identical DFN1010D-3 (SOT1215) packaging and 4-pin pinout (I, GND, O, O). This allows drop-in substitution within the same footprint when bias resistor values align with circuit requirements, though R1/R2 values differ across types and affect drive characteristics.
Does PDTC143XQA require external base resistors?
No, PDTC143XQA does not require external base resistors. It integrates R1 = 4.7 kΩ between input (pin 1) and base, and R2 = 10 kΩ between base and emitter (pin 2), forming a complete bias network. This eliminates two passive components per switch, simplifying layout and improving reliability in high-density designs.
What is the marking code for PDTC143XQA?
The binary marking code for PDTC143XQA is "11 11 01", laser-etched on the top surface of the DFN1010D-3 package. This 6-bit code uniquely identifies the part within the PDTC143X/123J/143Z/114YQA family and is used for traceability and automated optical inspection during assembly.
How does PDTC143XQA compare to BC847B in terms of board space and qualification?
PDTC143XQA occupies 1.1 × 1.0 mm in DFN1010D-3, versus 2.9 × 1.3 mm for BC847B in SOT23-reducing footprint by >70%. It also carries AEC-Q101 qualification out-of-box, whereas BC847B requires separate qualification testing. PDTC143XQA integrates bias resistors, eliminating two passives and associated layout area required by BC847B.
