Product details
Overview
PDTC144EQC-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 47 kΩ input and output bias resistors, delivers 100 mA output current, achieves 80× DC current gain at 5 mA collector current, and supports automotive-grade operation per AEC-Q101. It functions as a digital switch for controlling IC inputs or low-power loads in space-constrained PCBs.
For engineers reviewing the PDTC144EQC-Q datasheet, PDTC144EQC-Q pinout, PDTC144EQC-Q application, or PDTC144EQC-Q equivalent, key selection criteria include its 47 kΩ R1/R2 resistor values, 100 mA IO rating, 50 V VCEO, ultra-small 1.4 × 1.2 × 0.48 mm footprint, and AEC-Q101 qualification for automotive signal switching.
Technical Context
This RET integrates a monolithic NPN transistor with two precision silicon resistors (R1 = R2 = 47 kΩ) on a single die, eliminating external base resistors. Its internal resistor network enables direct logic-level drive from 3.3 V or 5 V microcontrollers without additional components.
The device operates with an off-state input voltage threshold of 1.2 V (typical) and on-state input voltage of 1.6 V (typical) at 2 mA collector current, ensuring robust noise immunity and predictable turn-on behavior in digital interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive and industrial bus interfacing. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| hFE | 80 - DC current gain at VCE = 5 V, IC = 5 mA; ensures reliable saturation with low base drive current. |
| R1 / R2 | 47 kΩ / 47 kΩ - Integrated base and emitter resistors; eliminates need for two external SMT resistors and reduces BOM count. |
| VCE(sat) | 100 mV - Collector-emitter saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes power loss in switching mode. |
| Tj(max) | 150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
Pinout & Package
Package: DFN1412D-3 (SOT8009), ultra-small leadless plastic package with side-wettable flanks (SWF), 1.4 mm × 1.2 mm × 0.48 mm body height, 0.8 mm pitch, and 0.5 mm max profile - optimized for AOI-compatible reflow soldering and high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signal directly from MCU GPIO or buffer output. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for both input and output paths. |
| 3 | Output (collector) | Switched high-side output node; drives loads connected between VCC and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified for automotive applications including engine control modules and body electronics - no derating required for 125 °C ambient. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom-terminated packages - improves manufacturing yield and traceability. |
| Ultra-low profile | 0.48 mm body height - allows placement beneath connectors or in stacked PCB assemblies where Z-height is constrained. |
| Integrated resistor ratio | R2/R1 = 1.0 ± 20% - ensures consistent biasing and predictable switching thresholds across production lots. |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |
|---|---|
Use Scenario: Switching door lock actuators and interior lighting circuits in BCMs using 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: Digital switch translating MCU GPIO signals into 12 V load control with built-in current limiting and ESD protection. Use Value: Eliminates two external resistors per channel, reducing PCB area by >0.5 mm² and enabling 20% higher channel density on compact BCM boards. | Use Scenario: Level-shifting and isolating 24 V sensor inputs to 3.3 V/5 V PLC controller inputs. IC Role / Device Role / Timing Role: Input stage translator providing galvanic decoupling and noise filtering via integrated resistor network. Use Value: Achieves <1 µs propagation delay and withstands repetitive 1 kV EFT pulses per IEC 61000-4-4 due to controlled internal impedance. |
| Consumer Appliance Control Board | Automotive Infotainment Power Sequencing |
Use Scenario: Enabling/disabling backlight LEDs and buzzer drivers in smart home appliances using battery-powered MCUs. IC Role / Device Role / Timing Role: Low-power load switch with <100 nA leakage in off-state and <100 mV saturation drop during active drive. Use Value: Extends battery life by minimizing quiescent current and thermal rise in thermally isolated enclosures. | Use Scenario: Controlling power-up sequencing of display drivers and audio amplifiers in head units. IC Role / Device Role / Timing Role: Precision timing element enabling staggered enable signals with <50 ns skew between channels.

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 |
|---|---|---|---|
| PDTC124EQC-Q | R1 = R2 = 22 kΩ; hFE = 60 at IC = 5 mA; lower input resistance increases base current demand. | Better suited for higher-speed switching (>100 kHz) due to reduced RC time constant but less noise-immune at low VIN. | Select when driving from 5 V logic with tighter timing budgets and lower thermal constraints. |
| BC847B-Q | Discrete NPN transistor without integrated resistors; requires external 47 kΩ base resistor; same SOT323 package. | Offers higher hFE (200–450) and lower VCE(sat) (65 mV), but increases component count and layout complexity. | Choose when maximum gain and minimal saturation loss are critical, and board space permits discrete resistor placement. |
Compared with PDTC124EQC-Q, PDTC144EQC-Q provides higher noise margin and lower base current draw, while BC847B-Q delivers superior analog linearity and lower conduction loss at the cost of added design effort and BOM items.

FAQ
What is the maximum continuous collector current for PDTC144EQC-Q?
The maximum continuous collector current (IO) 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 85 °C ambient, maximum sustainable current drops to approximately 65 mA under the same board conditions.
Does PDTC144EQC-Q require external base resistors?
No. PDTC144EQC-Q integrates both R1 (47 kΩ) and R2 (47 kΩ) bias resistors internally. It is designed for direct connection to logic outputs - no external base resistor is needed for standard 3.3 V or 5 V CMOS/TTL drive levels.
Is PDTC144EQC-Q compatible with automated optical inspection (AOI)?
Yes. Its DFN1412D-3 (SOT8009) package features side-wettable flanks, enabling reliable solder-joint inspection using standard AOI systems. This is confirmed in Section 2 ("Features and benefits") and Section 13 ("Soldering") of the official datasheet.
What is the off-state input voltage threshold (VI(off)) for reliable turn-off?
VI(off) is specified as 0.8 V (max) at VCE = 5 V and IC = 100 µA. At 25 °C, typical VI(off) is 1.2 V, providing ≥0.5 V noise margin against 1.8 V logic low levels - ensuring robust immunity to ground bounce and crosstalk in dense PCB layouts.
