Product details
Overview
PDTA143ZQC-Q from Nexperia is a 50 V, 100 mA PNP 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 47 kΩ feedback resistor (R2), delivers hFE = 100 at VCE = −5 V / IC = −10 mA, achieves VCE(sat) ≤ −100 mV, and is AEC-Q101 qualified for automotive digital switching applications.
For engineers reviewing the PDTA143ZQC-Q datasheet, PDTA143ZQC-Q pinout, PDTA143ZQC-Q application, or PDTA143ZQC-Q equivalent, this device serves as a space-optimized, drop-in replacement for discrete BJT + resistor networks in load switching, IC input control, and cost-sensitive digital logic interfacing where board area, solder joint inspection, and automotive reliability are critical.
Technical Context
This PNP RET uses an integrated bipolar junction transistor with two monolithically embedded resistors: R1 connects base to input, R2 connects base to emitter, enabling single-pin drive and eliminating external bias components. Its internal structure supports direct TTL/CMOS-level input compatibility with defined VI(on) and VI(off) thresholds.
The DFN1412D-3 package features side-wettable flanks for automated optical inspection (AOI) of solder joints, 0.5 mm profile height, and thermal resistance Rth(j-a) = 278 K/W on 70 µm FR4 PCB - optimized for high-density automotive and industrial PCBs requiring compact, reliable low-power switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| hFE | 100 (min) at VCE = −5 V, IC = −10 mA - Ensures stable saturation with low base drive current (IB ≈ −0.1 mA). |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA - Minimizes conduction loss and self-heating in power-switching nodes. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Fixed internal bias network eliminates external resistors; sets predictable turn-on/off thresholds and reduces BOM count. |
| Tj max | 150 °C - Junction temperature rating supporting operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics, including temperature cycling, HTRB, and ESD. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-small plastic 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) | Driven directly by logic-level signal; internal R1 connects this pin to base node. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path and reference for internal R2. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external resistors, reducing layout area and assembly steps in digital interface circuits. |
| Side-wettable flanks | Enables 100% automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield in automotive production. |
| 0.5 mm package height | Supports ultra-thin end equipment (e.g., infotainment modules, sensor hubs) where Z-axis clearance is constrained. |
| AEC-Q101 qualification | Validated for automotive-grade reliability - including temperature cycling, humidity, and lifetime stress testing per JEDEC standards. |
| −100 mA output rating | Sufficient drive strength for common digital loads (e.g., microcontroller GPIO protection, optocoupler input, small solenoids). |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and small solenoids in door modules and lighting controllers. IC Role / Device Role: High-side PNP switch controlling current flow from battery rail to load. Use Value: Integrated R1/R2 ensures consistent turn-on behavior across temperature, eliminating resistor drift-related timing variation. |
Use Scenario: Level-shifting and isolating 24 V field signals into 3.3 V/5 V PLC controller inputs. IC Role / Device Role: Digital input buffer with built-in pull-down and current limiting via internal resistor network. Use Value: Reduces component count per channel by two resistors, lowering BOM cost and PCB footprint in multi-channel I/O modules. |
| Consumer Appliance Control Board | Medical Diagnostic Device Interface |
Use Scenario: Enabling/disabling buzzer drivers and display backlight segments in smart home appliances. IC Role / Device Role: Low-power load switch activated by MCU GPIO pins. Use Value: −100 mV VCE(sat) minimizes power dissipation and heat generation in thermally constrained enclosures. |
Use Scenario: Safe, isolated activation of status indicators and audible alerts in Class II medical devices. IC Role / Device Role: Reinforced isolation barrier interface element with predictable off-state leakage (ICEO ≤ −5 µA at 150 °C). Use Value: AEC-Q101 qualification provides traceable reliability evidence required for IEC 62304 compliance documentation. |
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 |
|---|---|---|---|
| PDTC143ZQC-Q | NPN complement with identical R1/R2 values (4.7 kΩ/47 kΩ); same package and AEC-Q101 rating. | Requires inverted logic drive and low-side switching topology instead of high-side PNP configuration. | Select when circuit architecture uses NPN-based sink drivers or shared emitter configurations. |
| PDTA123JQC-Q | Lower R1 (2.2 kΩ) and higher R2/R1 ratio (21); hFE = 100 but optimized for lower IC (−5 mA typical). | Better suited for ultra-low-power microcontroller wake-up inputs or high-impedance sensing nodes. | Choose when drive current < 10 mA suffices and tighter VI(on)/VI(off) window (−0.6 V to −0.5 V) improves noise immunity. |
Compared with PDTC143ZQC-Q, PDTA143ZQC-Q enables high-side sourcing without level-shifting; versus PDTA123JQC-Q, it delivers higher output current headroom and wider input voltage tolerance, making it optimal for 24 V automotive load switching where robustness and margin are prioritized.

FAQ
What is the maximum continuous collector current for PDTA143ZQC-Q?
The 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 Figure 1: at 85 °C ambient, maximum allowable IC drops to approximately −65 mA to maintain Tj ≤ 150 °C.
Can PDTA143ZQC-Q replace a discrete BC857B transistor plus two external resistors?
Yes - PDTA143ZQC-Q replaces BC857B plus 4.7 kΩ and 47 kΩ resistors in high-side switch configurations. Its integrated R1/R2 matches the BC857B-based design's bias network, maintains identical VCE(sat) and hFE performance, and reduces PCB area by >60% while enabling AOI-compatible assembly.
What is the meaning of the marking code '8G' on the device top?
'8G' is the manufacturer's top-side marking for PDTA143ZQC-Q per Table 5. It uniquely identifies this specific variant within the PDTA143X/123J/143Z/114Y/124XQC-Q series and corresponds to the 4.7 kΩ/47 kΩ resistor combination and PNP polarity - verified during wafer sort and final test.
Does PDTA143ZQC-Q support reflow soldering with standard lead-free profiles?
Yes - the DFN1412D-3 package is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow. Recommended peak temperature is 260 °C with ≤ 60 seconds above 217 °C. Figure 37 provides the exact stencil and land pattern dimensions for reliable solder joint formation on side-wettable flanks.
