Product details
Overview
PDTC144TMB from Nexperia is an NPN resistor-equipped transistor (RET) in a DFN1006B-3 (SOT883B) package, designed for digital switching in space-constrained applications. It integrates a 47 kΩ input bias resistor (R1), supports 100 mA output current, exhibits 150 mV VCE(sat) at IC = 10 mA/IB = 0.5 mA, and is AEC-Q101 qualified for automotive use.
For engineers reviewing the PDTC144TMB datasheet, PDTC144TMB pinout, PDTC144TMB application, or PDTC144TMB equivalent, this device serves as a drop-in replacement for discrete base-resistor transistor configurations in low-current peripheral drivers, IC input control, and mobile logic interface circuits where board space and assembly cost are critical.
Technical Context
The PDTC144TMB integrates a single NPN silicon transistor with one external-base bias resistor (R1 = 47 kΩ, tolerance ±28%) and an open R2 terminal - enabling direct TTL/CMOS-level drive without external base resistors. Its internal structure eliminates need for separate bias network design and reduces PCB footprint by up to 60% versus discrete BJT + resistor solutions.
It operates with VCEO = 50 V, supports continuous IO = 100 mA, and delivers fT = 230 MHz at VCE = 5 V/IC = 10 mA, making it suitable for high-speed digital switching up to ~10 MHz edge rates while maintaining low saturation voltage and thermal resistance (Rth(j-a) = 500 K/W).
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 and industrial logic interfaces. |
| IO | 100 mA - Continuous output current rating; sufficient for driving LEDs, small relays, and logic inputs without external current amplification. |
| R1 | 47 kΩ (33–61 kΩ range) - Integrated base bias resistor; eliminates need for external pull-up/pull-down, simplifying layout and reducing BOM count. |
| VCE(sat) | 150 mV @ IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| fT | 230 MHz - Transition frequency confirms suitability for fast digital switching (e.g., UART, I²C level-shifting, enable signals) with clean edges. |
| Ptot | 250 mW @ Tamb ≤25 °C - Power dissipation limit defines thermal derating curve; requires <100 mW operation above 75 °C ambient. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive discrete semiconductors; validated for under-hood and infotainment module use. |
Pinout & Package
DFN1006B-3 (SOT883B) is a leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.37 mm, optimized for high-density PCB layouts and automated placement. Its low profile (0.37 mm max height) supports thin-profile mobile and wearable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts TTL/CMOS logic-high (≥2.0 V) to turn on transistor; no external base resistor required. |
| 2 | GND (emitter) | Emitter tied to system ground; serves as common reference for input and output paths; must be low-impedance for stable switching. |
| 3 | Output (collector) | Switched output node; sinks current to ground when active; connects to load (e.g., LED cathode, IC input, relay coil). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 47 kΩ (±28%) eliminates need for external base resistor, reducing component count and placement steps in SMT lines. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control and body electronics. |
| Ultra-small DFN1006B-3 package | 1.0 × 0.6 mm footprint with 0.37 mm height enables routing under fine-pitch BGAs and integration into sub-5 mm wearable modules. |
| Low VCE(sat) | 150 mV ensures <1.5 mW conduction loss at 10 mA, minimizing thermal rise in thermally constrained PCBs. |

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 |
|---|---|---|---|
| PDTC124TMB | R1 = 22 kΩ (vs. 47 kΩ); higher base drive current required for same IC. | Better suited for lower-VCC (1.8 V) logic families needing stronger base injection. | Select when driving loads requiring faster turn-on at sub-2.0 V input thresholds. |
| PDTA144TMB | PNP complement; R1 = 47 kΩ; same package and bias topology but inverted polarity. | Used for high-side switching or complementary push-pull outputs where sourcing current is required. | Choose for bidirectional signal control or when matching PNP/NPN RET pairs in dual-rail logic interfaces. |
Compared with PDTC124TMB and PDTA144TMB, the PDTC144TMB provides optimal base impedance for 3.3 V/5 V CMOS drive with minimal power loss, while its NPN configuration suits standard low-side switching topologies prevalent in automotive and portable electronics.

FAQ
What is the function of the open R2 terminal in PDTC144TMB?
The R2 terminal is unconnected (open) inside the PDTC144TMB, meaning only one integrated base bias resistor (R1) is present. This configuration supports standard single-resistor NPN switching where the base is driven directly from a logic source, eliminating need for emitter-feedback or dual-resistor bias networks used in precision analog applications.
Can PDTC144TMB be used in 1.8 V logic systems?
Yes - with VCE(sat) = 150 mV and typical hFE >100 at IC = 1 mA, the device reliably switches at 1.8 V supply when driven with ≥0.5 mA base current. However, due to its 47 kΩ R1, minimum input voltage for guaranteed turn-on is ~2.0 V; for robust 1.8 V operation, PDTC124TMB (R1 = 22 kΩ) is preferred.
How does the DFN1006B-3 package affect thermal performance?
The DFN1006B-3 package has Rth(j-a) = 500 K/W in free air on FR4 PCB, limiting continuous power dissipation to 250 mW at 25 °C ambient. For sustained 100 mA loads, thermal relief via copper pour under pin 2 (emitter) or forced airflow is recommended to maintain junction temperature below 150 °C.
Is PDTC144TMB pin-compatible with other SOT883B devices?
Yes - all SOT883B-packaged devices share identical 1.0 × 0.6 mm outline and 3-terminal pin arrangement (input/emitter/collector). However, electrical functionality (NPN vs. PNP, R1 value, current rating) varies; mechanical compatibility does not guarantee functional interchangeability without circuit validation.
