Product details
Overview
PDTA144EQC-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 47 kΩ input and output bias resistors, delivers −100 mA output current, achieves −100 mV VCE(sat) at IC = −10 mA/IB = −0.5 mA, and is AEC-Q101 qualified for automotive load switching and IC input control.
For engineers reviewing the PDTA144EQC-Q datasheet, PDTA144EQC-Q pinout, PDTA144EQC-Q application, or PDTA144EQC-Q equivalent, this page provides verified pin functions, automotive-grade thermal derating curves, validated DC current gain (hFE = 80 at IC = −5 mA), off-state input voltage range (−1.2 V to −0.8 V), and direct replacement guidance against BC857-Q series.
Technical Context
This PNP RET uses an integrated bipolar transistor with two monolithic silicon resistors (R1 = R2 = 47 kΩ) forming a fixed-current bias network. Its simplified three-terminal structure eliminates external base resistors, enabling direct logic-level drive from microcontrollers or gate drivers.
The device operates with open-base VCEO = −50 V and supports continuous ambient temperatures from −55 °C to +150 °C. Its side-wettable flanks and 0.5 mm profile meet AOI-solder-joint inspection requirements for high-reliability automotive PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, relays, and small solenoids. |
| VCE(sat) | −100 mV at IC = −10 mA/IB = −0.5 mA: Low saturation voltage minimizes power loss and self-heating in switching mode. |
| hFE | 80 at VCE = −5 V, IC = −5 mA: Confirmed DC current gain ensures reliable turn-on with minimal base drive overhead. |
| R1 / R2 | 47 kΩ / 47 kΩ: Matched on-die bias resistors eliminate discrete components and reduce BOM count by one resistor pair. |
| Tj(max) | 150 °C: Maximum junction temperature rating supports operation in under-hood environments without forced cooling. |
| Package | DFN1412D-3 (SOT8009): 1.4 × 1.2 × 0.48 mm ultra-small footprint with side-wettable flanks for automated optical solder inspection. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, surface-mount plastic package with side-wettable flanks, 0.8 mm pitch, and 0.5 mm maximum height. Its compact 1.4 mm × 1.2 mm body enables high-density routing in space-constrained automotive ECUs and sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level control signal; internal R1 connects this pin to emitter, defining base current path. |
| 2 | GND (emitter) | Common reference node and current return path; tied to system ground or low-side rail. |
| 3 | Output (collector) | Switches high-side loads referenced to positive supply; sinks current when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Monolithic 47 kΩ R1 and R2 eliminate external base resistors, reducing component count and layout area. |
| AEC-Q101 qualification | Stress-tested per automotive discrete semiconductor standard, supporting deployment in engine control, lighting, and body electronics. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom terminals, improving manufacturing yield and traceability. |
| Ultra-low profile | 0.48 mm typical height allows placement beneath connectors or in stacked module assemblies without mechanical interference. |
| Thermal derating support | Rated 450 mW on 70 µm copper FR4; power dissipation drops linearly above 25 °C ambient, enabling predictable thermal design. |
Applications
| Automotive LED Headlamp Control | Industrial PLC Digital Input Conditioning |
|---|---|
Use Scenario: Switching 12 V/24 V LED arrays in adaptive front-lighting systems (AFS) with PWM dimming. IC Role / Device Role / Timing Role: High-side PNP switch controlling current flow to LED string; driven by MCU GPIO with no external pull-up or base resistor. Use Value: −100 mV VCE(sat) limits conduction loss to <10 mW at 100 mA, reducing thermal load in sealed headlamp housings. | Use Scenario: Level-shifting and current-limiting 24 V industrial field signals into 3.3 V/5 V PLC controller inputs. IC Role / Device Role / Timing Role: Signal interface transistor converting sinking field inputs to sourcing logic-compatible levels. Use Value: −1.2 V to −0.8 V VI(off) ensures clean cutoff across −40 °C to +100 °C, preventing false triggers in noisy factory environments. |
| Automotive Door Module Load Switching | Consumer Appliance Motor Driver Stage |
Use Scenario: Driving window lift motors, mirror actuators, and lock solenoids in centralized door control units. IC Role / Device Role / Timing Role: Medium-power load switch interfacing MCU outputs to inductive loads via flyback diode protection. Use Value: 50 V VCEO withstands load-dump transients up to ISO 7637-2 Pulse 5a (−120 V peak), eliminating need for external TVS clamping. | Use Scenario: Enabling/disabling small brushed DC motors in smart washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Solid-state replacement for mechanical relays in motor enable paths, supporting 100 k-cycle lifetime. Use Value: 100 mA IO rating matches typical motor hold currents; built-in resistors simplify PCB layout versus discrete BJT + resistor solutions. |
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 |
|---|---|---|---|
| PDTC144EQC-Q | NPN complement with identical R1/R2 = 47 kΩ, same SOT8009 package, but opposite polarity and +100 mV VCE(sat). | Requires high-side driver configuration instead of low-side; unsuitable for direct replacement where PNP sourcing is mandatory. | Select only when circuit topology permits NPN low-side switching and board layout allows polarity reversal. |
| BC857B-Q | Discrete PNP BJT without integrated resistors; requires external 47 kΩ base resistor; same VCEO/IO ratings but larger SOT323 footprint. | Increases BOM count and layout area; lacks AEC-Q101 qualification out-of-box; requires separate reliability validation. | Choose only if legacy designs mandate pin-for-pin compatibility with BC857 family or require adjustable base bias. |
Compared with PDTC144EQC-Q, PDTA144EQC-Q provides native high-side sourcing and avoids level-shifting complexity; compared with BC857B-Q, it reduces component count by two resistors and guarantees automotive qualification without additional testing.

FAQ
What is the maximum allowable continuous collector current for PDTA144EQC-Q?
The maximum continuous output current is −100 mA, specified at Tamb ≤ 25 °C on a standard FR4 PCB with 70 µm copper. Derating applies above 25 °C ambient: power dissipation decreases linearly to zero at 150 °C junction temperature, limiting usable current in high-temperature environments.
Does PDTA144EQC-Q require an external base resistor?
No. PDTA144EQC-Q integrates both R1 (47 kΩ) and R2 (47 kΩ) bias resistors internally. Pin 1 (input) connects directly to logic-level control signals-no external base resistor is needed, simplifying schematic design and reducing PCB footprint.
Can PDTA144EQC-Q be used in high-voltage transient environments like automotive load dump?
Yes. With VCEO = −50 V and VCBO = −50 V, PDTA144EQC-Q withstands common automotive transients including ISO 7637-2 Pulse 5a (−120 V peak) when used with appropriate external clamping (e.g., TVS diode at collector). Its AEC-Q101 qualification confirms robustness under stress conditions.
How does the side-wettable flank feature benefit manufacturing?
Side-wettable flanks expose solder along the package perimeter, enabling automated optical inspection (AOI) systems to verify solder joint quality on all three terminals-including the bottom-mounted emitter (Pin 2)-without X-ray. This improves first-pass yield and traceability in automotive-tier-1 production lines.
