Product details
Overview
PDTC143ZQC-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It integrates 4.7 kΩ input bias resistor (R1) and 47 kΩ emitter feedback resistor (R2), enabling direct digital logic interface without external components. Designed for automotive-grade switching in load control and IC input driving, it delivers 100 mV VCE(sat) at IC = 5 mA / IB = 0.5 mA.
For engineers reviewing the PDTC143ZQC-Q datasheet, PDTC143ZQC-Q pinout, PDTC143ZQC-Q application, or PDTC143ZQC-Q equivalent, this device serves as an AEC-Q101-qualified, space-constrained alternative to discrete BJT + resistor networks in digital signal routing, microcontroller I/O buffering, and low-power load switching where board area and assembly cost are critical.
Technical Context
This RET implements a monolithic NPN transistor with two integrated precision thin-film resistors-R1 connected between base and input, R2 between base and emitter-forming a built-in current-limiting and bias-stabilizing network. Its architecture eliminates external base resistors while maintaining predictable DC current gain (hFE = 100 min at VCE = 5 V, IC = 10 mA).
The device operates within a −55 °C to +150 °C ambient range, supports Automatic Optical Inspection (AOI) via side-wettable flanks, and achieves thermal resistance of 278 K/W (junction-to-ambient, 70 µm copper PCB), enabling reliable operation in thermally constrained automotive ECUs and industrial controllers.
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 output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Integrated bias network enables direct 3.3 V/5 V CMOS/TTL interface without external resistors. |
| VCE(sat) | 100 mV @ IC = 5 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors; suitable for under-hood and body-control modules. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for AOI-compatible reflow soldering. |
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 a 0.8 mm pitch. Its low 0.5 mm profile supports high-density PCB layouts and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive directly from MCU GPIO or buffer outputs. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current and reference for R2. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 network | Eliminates 2 external resistors per switch channel, reducing BOM count and placement footprint by >30% vs discrete BJT solutions. |
| Side-wettable flanks | Enables full-spectrum AOI verification of solder joint integrity on bottom terminals-critical for automotive zero-defect manufacturing. |
| Low 0.5 mm height | Allows stacking beneath connectors or shields in ultra-thin modules such as ADAS camera housings and smart sensors. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, and ESD per automotive stress standards-no additional qualification needed for Tier 1 designs. |
Applications
| Automotive Body Control | Industrial PLC I/O |
|---|---|
|

IC Role / Device Role / Timing Role: Serves as a low-leakage, low-noise enable switch for precision analog circuitry powered from LDOs. Use Value: ICEO ≤ 5 µA at 150 °C ensures minimal standby current drain; R1/R2 ratio stabilizes bias point against temperature drift. |
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 |
|---|---|---|---|
| PDTC143XQC-Q | R1 = 4.7 kΩ, R2 = 10 kΩ → lower R2/R1 ratio (2.13) yields higher base current and faster switching but reduced input impedance. | Better suited for high-speed digital switching (e.g., clock gating); less tolerant of floating inputs due to lower R2. | Select when minimizing propagation delay is critical and input drive strength exceeds 0.5 mA. |
| BC847B-Q | Discrete NPN BJT (no integrated resistors); requires external RB and RE; hFE = 200–450 vs RET's fixed 100. | Offers design flexibility for custom biasing but increases layout complexity and component count. | Choose when precise hFE tuning or adjustable saturation characteristics are required. |
Compared with PDTC143XQC-Q, PDTC143ZQC-Q provides higher R2 for improved noise immunity and input float tolerance, while BC847B-Q trades integration for biasing flexibility-making PDTC143ZQC-Q optimal for cost-sensitive, high-volume automotive and industrial digital I/O where layout simplicity and AEC compliance are mandatory.

FAQ
What is the maximum continuous collector current for PDTC143ZQC-Q?
The absolute maximum continuous collector current is 100 mA at Tamb ≤ 25 °C on a standard FR4 PCB with 70 µm copper. Derating applies above 25 °C per Fig. 1: at 85 °C ambient, maximum sustainable IC drops to approximately 65 mA to maintain junction temperature below 150 °C.
Can PDTC143ZQC-Q be used with 3.3 V logic inputs?
Yes. With VI(on) = 0.9 V (typical) and VI(off) = 0.5 V (max), the device reliably switches on with standard 3.3 V CMOS outputs (VOH ≥ 2.4 V) and remains off with logic-low states (VOL ≤ 0.4 V), providing robust noise margin in noisy environments.
Does PDTC143ZQC-Q require external pull-down resistors?
No. The internal R2 (47 kΩ) from base to emitter provides inherent pull-down functionality, ensuring the transistor stays off during MCU reset or floating input conditions-eliminating the need for external biasing components in most digital interface applications.
How does the DFN1412D-3 package support automated optical inspection?
The side-wettable flanks expose solderable metal along the vertical edges of the package, allowing AOI systems to capture clear side-view images of the solder fillet geometry. This enables quantitative assessment of wetting angle, solder volume, and voiding-meeting IPC-A-610 Class 3 requirements for automotive electronics.
