Product details
Overview
PDTC143XQC-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It integrates 4.7 kΩ input bias resistor (R1) and 10 kΩ feedback resistor (R2), enabling direct logic-level switching without external bias components. Used for digital load switching, IC input control, and automotive signal conditioning where space-constrained PCBs require AEC-Q101-qualified discrete solutions.
For engineers reviewing the PDTC143XQC-Q datasheet, PDTC143XQC-Q pinout, PDTC143XQC-Q application, or PDTC143XQC-Q equivalent, this part serves as a drop-in replacement for BC847-Q series transistors in digital switching circuits-offering verified 100 mA output current, 50 V VCEO, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This RET implements an integrated NPN bipolar junction transistor with two monolithically embedded thin-film resistors: R1 (4.7 kΩ) connected between base and input, and R2 (10 kΩ) between base and emitter. The configuration enables single-resistor drive operation, eliminating external base bias networks while maintaining predictable saturation behavior under logic-level inputs (VI(on) = 1.5–2.5 V at IC = 20 mA).
Designed for high-volume automated assembly, its DFN1412D-3 package features side-wettable flanks for AOI-compatible solder joint inspection and supports thermal derating to 360 mW at 25 °C ambient on standard FR4 PCBs. Junction temperature remains within safe limits up to 150 °C, validated per AEC-Q101 stress testing protocols.
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 / R2 | 4.7 kΩ / 10 kΩ - Pre-biased resistor network eliminates need for external base resistors in digital interface designs. |
| VCE(sat) | ≤100 mV at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | 50 (min) at VCE = 5 V, IC = 10 mA - Guaranteed DC current gain ensures reliable turn-on with minimal drive current. |
| Tj(max) | 150 °C - Maximum junction temperature rating; qualified per AEC-Q101 for under-hood automotive use. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for AOI compatibility. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless plastic package with side-wettable flanks, measuring 1.4 mm × 1.2 mm × 0.48 mm and featuring 0.8 mm pitch. Its low profile (0.5 mm max height) supports high-density routing and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level signals (VI(on) ≤ 2.5 V) to activate transistor. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and R2 connection. |
| 3 | Output (collector) | Switched output node; sinks up to 100 mA to ground when driven; connects to load cathode or logic input. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| PDTC123JQC-Q | R1 = 2.2 kΩ, R2 = 47 kΩ; hFE min = 100; lower VI(on) threshold (0.75 V typ) | Better suited for weak-drive sources (e.g., open-drain I²C lines); higher R2 improves noise immunity in noisy environments | Select when interfacing with low-current or high-impedance logic sources requiring higher input sensitivity. |
| BC847B-Q | Discrete NPN transistor (no built-in resistors); requires external base resistor; same SOT323 package | Offers greater design flexibility for custom biasing but increases component count and layout complexity | Choose only if variable gain, adjustable saturation, or non-standard biasing schemes are required. |
Compared with PDTC123JQC-Q, PDTC143XQC-Q delivers higher drive strength at logic-high inputs due to lower R1, while BC847B-Q trades integration for configurability-making PDTC143XQC-Q optimal for cost- and space-sensitive automotive digital switching where AEC-Q101 compliance is mandatory.

FAQ
What is the maximum continuous collector current for PDTC143XQC-Q?
The PDTC143XQC-Q supports a continuous output current (IO) of 100 mA under standard conditions (Tamb ≤ 25 °C, FR4 PCB with 35 µm copper). Derating applies above 25 °C ambient, reaching zero at 125 °C per the published power derating curve. This rating is validated for both steady-state and pulsed operation per IEC 60134 limiting values.
Does PDTC143XQC-Q require an external base resistor?
No. PDTC143XQC-Q integrates a 4.7 kΩ input resistor (R1) and a 10 kΩ feedback resistor (R2), enabling direct connection to logic-level voltage sources without external bias components. This eliminates two passive parts per channel and reduces PCB footprint, making it ideal for high-density digital interface applications.
Is PDTC143XQC-Q suitable for automotive applications?
Yes. PDTC143XQC-Q is qualified per AEC-Q101 for discrete semiconductors and explicitly recommended for automotive use. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life, supporting deployment in body control modules, lighting systems, and infotainment peripherals.
How does the DFN1412D-3 package support automated optical inspection (AOI)?
The DFN1412D-3 package features side-wettable flanks-exposed metal on the vertical edges of the terminals-that allow solder paste to wick upward during reflow. This creates a visible fillet detectable by AOI systems, enabling reliable, non-destructive verification of solder joint integrity without X-ray inspection.
