Product details
Overview
PDTC143XQAZ from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a leadless DFN1010D-3 (SOT1215) package, integrating 4.7 kΩ and 10 kΩ bias resistors. It functions as a digital switch for IC input control, delivers 100 mA output current, features 0.37 mm ultra-low profile, and is AEC-Q101 qualified for automotive use.
For engineers reviewing the PDTC143XQAZ datasheet, PDTC143XQAZ pinout, PDTC143XQAZ application, or PDTC143XQAZ equivalent, this page provides verified pin functions, confirmed thermal resistance (284 K/W on 4-layer FR4), exact R1/R2 values (4.7 kΩ / 10 kΩ), VI(on)/VI(off) thresholds (1.5–2.5 V / 0.3–0.8 V), and direct BC847-series replacement guidance.
Technical Context
This RET integrates an NPN transistor with two monolithic silicon resistors-R1 connected between base and input, R2 between base and emitter-enabling single-pin digital drive without external bias components. Its simplified switching architecture eliminates base resistor selection and layout overhead.
Designed for high-density SMT assembly, it supports Automatic Optical Inspection (AOI) due to visible side pads and achieves 100 mA continuous output with VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, while maintaining AEC-Q101 qualification for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving logic inputs, LEDs, or small relays. |
| R1 / R2 | 4.7 kΩ / 10 kΩ - Integrated bias network sets fixed gain and ensures reliable saturation with TTL/CMOS-compatible input levels. |
| VCE(sat) | ≤100 mV at IC = 10 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| Tj(max) | 150 °C - Maximum junction temperature; supports operation in engine control units and powertrain modules. |
| Rth(j-a) | 284 K/W (4-layer PCB) - Thermal resistance determines safe power dissipation limit (440 mW at Tamb = 25 °C). |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 3-terminal, leadless, ultra-thin surface-mount package measuring 1.1 × 1.0 × 0.37 mm with solderable side pads for AOI compatibility and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Digital signal entry point; connects internally to R1, enabling direct microcontroller GPIO drive without external resistor. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference and current return path. |
| 3 & 4 | Output (collector) | Dual-collector terminals provide parallel current paths and lower thermal resistance; both connect to load. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing BOM count and PCB area by ~2.5 mm² per instance. |
| Ultra-low profile (0.37 mm) | Enables use in space-constrained modules such as ADAS camera housings and compact ECU stacks. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to +150 °C) and mechanical stress, supporting Tier-1 production. |
| Visible side pads | Supports automated optical inspection of solder joints, improving first-pass yield in high-volume SMT lines. |
| Reduced pick-and-place cost | Single-component placement replaces three-part (transistor + two resistors) sequence, cutting placement time and feeder usage. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |

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 lower input current requirement (~90 µA vs 350 µA). | Better suited for ultra-low-power MCU GPIOs with weak drive strength; less suitable for noisy industrial environments. | Select when minimizing input current is critical and VI(on) threshold must be ≤1.1 V. |
| BC847B, SOT-23 | Discrete NPN transistor requiring external 10 kΩ base resistor; no integrated R2; larger SOT-23 footprint (2.9 × 1.3 mm). | Requires additional passives and PCB area; lacks AEC-Q101 qualification and AOI-friendly packaging. | Choose only if legacy design reuse or availability constraints prevent adoption of RET architecture. |
Compared with PDTC123JQA, PDTC143XQAZ offers higher input drive tolerance and better noise immunity; compared with BC847B, it reduces total solution size by 70% and eliminates resistor placement risk in high-reliability systems.

FAQ
What is the maximum continuous collector current for PDTC143XQAZ?
The maximum continuous collector current is 100 mA, validated under standard FR4 PCB conditions (4-layer copper, tin-plated). Derating applies above 25 °C ambient: power dissipation drops linearly to zero at 150 °C junction temperature, with Rth(j-a) = 284 K/W defining the thermal slope.
Does PDTC143XQAZ require external base resistors?
No. PDTC143XQAZ integrates R1 = 4.7 kΩ and R2 = 10 kΩ internally, forming a complete bias network. This eliminates the need for external base resistors and reduces PCB footprint, BOM count, and assembly steps in digital switching circuits.
Is PDTC143XQAZ compatible with reflow soldering processes?
Yes. The DFN1010D-3 (SOT1215) package is qualified for standard lead-free reflow profiles (J-STD-020). Nexperia provides detailed footprint and stencil recommendations-including 0.35 mm solder land width and 0.45 mm paste aperture-for reliable joint formation and AOI compatibility.
How does PDTC143XQAZ differ from BC847-series transistors?
PDTC143XQAZ integrates bias resistors, uses a smaller DFN1010D-3 package (1.1 × 1.0 mm vs SOT-23's 2.9 × 1.3 mm), is AEC-Q101 qualified, and supports AOI. BC847 requires two external resistors, lacks automotive qualification, and occupies ~7× more board area.
