Product details
Overview
PDTA143EQC-Q 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 and 4.7 kΩ base-emitter bias resistors, delivers −100 mA output current, exhibits −100 mV VCE(sat) at IC = −10 mA/IB = −0.5 mA, and is AEC-Q101 qualified for automotive digital switching applications.
For engineers reviewing the PDTA143EQC-Q datasheet, PDTA143EQC-Q pinout, PDTA143EQC-Q application, or PDTA143EQC-Q equivalent, this device serves as a space-optimized, AOI-compatible replacement for discrete PNP + resistor networks in load switching, IC input control, and cost-sensitive automotive digital circuits.
Technical Context
This PNP RET integrates two monolithic silicon resistors-R1 (4.7 kΩ) connected between base and input, and R2 (4.7 kΩ) between base and emitter-to form a single-input, three-terminal active switch. Its internal transistor features VCEO = −50 V, hFE = 30 (min) at VCE = −5 V/IC = −10 mA, and fT = 180 MHz (typ).
The device operates with VI(on) = −2.5 to −1.9 V at VCE = −0.3 V/IC = −20 mA and VI(off) = −1.1 to −0.5 V at VCE = −5 V/IC = −100 µA, enabling robust logic-level interfacing. Its 0.48 mm profile and side-wettable flanks support automated optical inspection and high-density PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; defines safe operating range for automotive 12 V/24 V rail switching. |
| IO | −100 mA - Continuous DC output current capability; supports driving small relays, LEDs, or logic inputs without external current limiting. |
| VCE(sat) | −100 mV (max) at IC = −10 mA/IB = −0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| R1 / R2 | 4.7 kΩ / 4.7 kΩ - Matched on-chip bias resistors eliminate need for two external components and reduce layout area by ~3 mm². |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for reliable reflow solder joint inspection. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors; suitable for under-hood and cabin control modules. |
| hFE | 30 (min) at VCE = −5 V/IC = −10 mA - Guaranteed DC current gain ensures predictable base drive requirements across temperature. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, surface-mount plastic package with side-wettable flanks, 0.8 mm pitch, and 0.48 mm height. Its compact footprint (1.4 × 1.2 mm) enables high-density routing in space-constrained automotive ECUs and portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level control signal; internally connected to R1 (4.7 kΩ) leading to transistor base. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; also connects to R2 (4.7 kΩ) for internal base biasing. |
| 3 | Output (collector) | Switched high-side output node; sinks current when input is low (active-low logic interface). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates two external SMD resistors, reducing BOM count, placement time, and PCB real estate. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield and traceability. |
| Ultra-low profile | 0.48 mm max height supports thin-profile designs such as ADAS sensors and infotainment modules. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per AEC standard. |
| −100 mA output rating | Sufficient to directly drive small solenoids, indicator LEDs, or CMOS/TTL inputs without additional buffering. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |

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 |
|---|---|---|---|
| PDTC143EQC-Q | NPN complement with identical R1/R2 (4.7 kΩ), same package and AEC-Q101 rating, but opposite polarity switching. | Requires inverted logic drive and sourcing (not sinking) output configuration; unsuitable where high-side switching is mandatory. | Select when circuit topology uses NPN-based active-high control and shares same bias resistor values. |
| BC857B-Q | Discrete PNP transistor without built-in resistors; requires external 4.7 kΩ base resistor; same VCEO/IO ratings. | Increases BOM count and PCB area; lacks AOI-friendly side-wettable flanks and tighter VI(on)/VI(off) tolerances. | Choose only if legacy design reuse mandates discrete transistor footprint or resistor value customization is required. |
Compared with PDTC143EQC-Q, PDTA143EQC-Q provides native active-low switching with reduced layout complexity; compared with BC857B-Q, it eliminates two passives and enables AOI validation-critical for automotive production traceability.

FAQ
What is the maximum continuous collector current for PDTA143EQC-Q?
The maximum continuous collector current is −100 mA at Tamb ≤ 25 °C on a standard FR4 PCB with 35 µm copper. Derating applies above 25 °C per Figure 1; at 75 °C ambient, maximum allowable current drops to approximately −60 mA to maintain junction temperature ≤ 150 °C.
Does PDTA143EQC-Q require an external base resistor?
No. PDTA143EQC-Q integrates both R1 (4.7 kΩ) and R2 (4.7 kΩ) internally, eliminating the need for external base biasing components. The device operates as a true three-terminal switch: apply logic-low to Pin 1 to turn on the PNP transistor and sink current from Pin 3 to Pin 2.
Can PDTA143EQC-Q be used in high-frequency switching applications?
Its fT is 180 MHz (typ), but it is not optimized for RF or fast PWM. Designed for digital switching up to ~100 kHz, its primary value lies in simplifying DC/low-frequency load control-not signal amplification or high-speed edge rates.
How does the side-wettable flank design benefit manufacturing?
Side-wettable flanks allow automated optical inspection (AOI) systems to verify solder joint formation on all three terminals without requiring X-ray. This reduces final-test escapes and supports zero-defect goals in automotive Tier-1 production lines.
