Product details
Overview
PDTA143XQC-QZ from Nexperia is a 50 V, 100 mA PNP 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 10 kΩ feedback resistor (R2), delivers −100 mV VCE(sat) at −10 mA/−0.5 mA drive, and is AEC-Q101 qualified for automotive digital switching applications.
For engineers reviewing the PDTA143XQC-QZ datasheet, PDTA143XQC-QZ pinout, PDTA143XQC-QZ application, or PDTA143XQC-QZ equivalent, this device serves as a space-optimized, AOI-compatible replacement for discrete BJT + resistor networks in load switching, IC input control, and cost-sensitive digital logic interfaces.
Technical Context
This PNP RET uses an integrated silicon transistor with built-in R1–R2 bias network to eliminate external base resistors. Its fixed resistor ratio (R2/R1 = 2.13 typ.) enables predictable turn-on/off thresholds and stable current gain (hFE = 50 min at −5 V, −10 mA).
The DFN1412D-3 package supports high-density PCB layouts with 0.5 mm profile and side-wettable flanks for automated optical solder-joint inspection-critical for automotive production traceability and reliability assurance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; supports robust operation in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs without external amplification. |
| VCE(sat) | −100 mV @ −10 mA/−0.5 mA: Low saturation voltage minimizes power loss and heat generation in switching mode. |
| R1 / R2 | 4.7 kΩ / 10 kΩ: Pre-laid bias network simplifies design, reduces bill-of-materials count, and ensures consistent switching behavior across temperature. |
| hFE | 50 min @ −5 V, −10 mA: Guaranteed DC current gain enables reliable digital on/off control without gain-dependent timing uncertainty. |
| Tj max | 150 °C: Junction temperature rating aligned with AEC-Q101 automotive qualification for under-hood and infotainment environments. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-small surface-mount package measuring 1.4 × 1.2 × 0.48 mm with side-wettable flanks for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level or microcontroller GPIO signal; internal R1 connects here to emitter for current-limited base drive. |
| 2 | GND (emitter) | Common reference node and current return path; tied to system ground in standard PNP switch configuration. |
| 3 | Output (collector) | Switches high-side loads (e.g., LED anode, relay coil); sinks current when active, open-circuit when off. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use per stress-test requirements including temperature cycling, HTRB, and ESD; supports PPAP documentation. |
| Side-wettable flanks | Enables 100% automated optical inspection of solder joints-eliminates X-ray requirement and improves first-pass yield in SMT lines. |
| 0.5 mm package height | Reduces board profile for slim modules (e.g., dashboard displays, ADAS sensors) where Z-axis clearance is constrained. |
| −7 V VEBO | Emitter-base breakdown rating allows safe operation with negative transients common in automotive CAN/LIN bus environments. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door modules and lighting controllers. IC Role / Device Role / Timing Role: High-side PNP switch controlled by MCU GPIO; provides level-shifted, current-limited drive with fast turn-off due to integrated R2. Use Value: Eliminates two external resistors per channel, reducing PCB area by >0.5 mm² and assembly cost by $0.008/unit at volume. |
Use Scenario: Conditioning 24 V industrial sensor signals into 3.3 V/5 V logic levels for FPGA or ARM-based controllers. IC Role / Device Role / Timing Role: Digital input buffer with hysteresis-like behavior enabled by R1–R2 feedback; rejects noise on long cables. Use Value: Replaces BC857-Q + dual-resistor solution while maintaining <1 µs propagation delay and −40 °C to +125 °C operation. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Interface |
Use Scenario: Enabling sequential power-up of subsystems (e.g., display backlight, motor driver, comms IC) in smart home hubs. IC Role / Device Role / Timing Role: Controlled enable switch with defined VI(on)/VI(off) thresholds (−1.5 V / −0.6 V typ.) for clean state transitions. Use Value: Guarantees monotonic power sequencing without external RC timing components; supports IEC 61000-4-2 ±8 kV ESD immunity. |
Use Scenario: Isolating low-voltage microcontroller pins from higher-voltage analog front-end circuits in portable ultrasound units. IC Role / Device Role / Timing Role: Logic-level translator and fault-isolation element; blocks leakage currents during standby via high ICEO rejection (−100 nA max). Use Value: Meets IEC 60601-1 creepage/clearance requirements with 0.8 mm pitch and no exposed leads; reduces risk of cross-talk in mixed-signal boards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143XQC-Q | NPN complement with identical R1/R2 values (4.7 kΩ/10 kΩ), same package and AEC-Q101 rating. | Requires inverted logic drive and low-side switching topology; not drop-in for high-side PNP configurations. | Select when circuit architecture uses NPN-driven loads referenced to ground (e.g., sinking LED cathodes). |
| BC857B-Q | Discrete PNP BJT (no integrated resistors); requires external base resistor network; same SOT323 package. | Offers adjustable biasing and higher hFE (200–450), but increases component count and layout sensitivity. | Choose when precise gain tuning or thermal derating flexibility is required beyond fixed RET performance envelopes. |
Compared with PDTC143XQC-Q, PDTA143XQC-QZ enables high-side switching without logic inversion; versus BC857B-Q, it trades design flexibility for reduced BOM count, smaller footprint, and guaranteed bias stability across temperature and process variation.

FAQ
What is the maximum continuous current rating for PDTA143XQC-QZ?
The PDTA143XQC-QZ is rated for −100 mA continuous collector current (IO) at Tamb ≤ 25 °C on a standard FR4 PCB with 35 µm copper. Derating applies above 25 °C per Fig. 1; at 85 °C ambient, maximum usable current drops to ~65 mA to maintain Tj ≤ 150 °C.
Does PDTA143XQC-QZ require external base resistors?
No. The device integrates a 4.7 kΩ input resistor (R1) and 10 kΩ feedback resistor (R2) internally. These eliminate the need for external bias components, reduce PCB area, and ensure consistent switching thresholds across manufacturing lots and temperature ranges.
Can PDTA143XQC-QZ be used in high-frequency switching applications?
It is optimized for DC and low-frequency digital switching (≤100 kHz). While its built-in transistor has fT = 180 MHz, the integrated resistors limit slew rate and increase propagation delay; it is not recommended for PWM dimming above 20 kHz or RF signal paths.
How does the side-wettable flank design benefit manufacturing?
The side-wettable flanks on the DFN1412D-3 package allow automated optical inspection (AOI) systems to verify solder joint quality directly at the package edge-replacing costly and slower X-ray inspection, improving defect detection for automotive-grade production traceability.
