Product details
Overview
PDTC144ET-QVL from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, featuring integrated 47 kΩ input bias resistor (R1) and 47 kΩ emitter feedback resistor (R2), 50 V VCEO, 100 mA IO, and optimized for automotive digital switching applications such as IC input control and load switching.
For engineers reviewing the PDTC144ET-QVL datasheet, PDTC144ET-QVL pinout, PDTC144ET-QVL application, or PDTC144ET-QVL equivalent, key selection criteria include built-in resistor ratio (R2/R1 = 1.0 typ), guaranteed off-state input voltage (VI(off) = 1.2 V typ), on-state input voltage (VI(on) = 1.6 V typ), thermal resistance (Rth(j-a) = 500 K/W), and AEC-Q101 qualification status.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed thin-film resistors on a single die: R1 connects base to input terminal, R2 connects base to emitter. The fixed R2/R1 ratio of 1.0 enables predictable saturation behavior under varying temperature (−40 °C to +150 °C) and ensures stable logic-level interfacing without external bias components.
It operates as a single-stage digital switch with defined turn-on (VI(on) ≤ 3 V at IC = 2 mA) and turn-off (VI(off) ≥ 0.8 V at IC = 100 µA) thresholds, eliminating need for discrete base resistors while maintaining hFE ≥ 80 at IC = 5 mA and VCE = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, relays, and logic inputs. |
| R1 | 47 kΩ (33–61 kΩ) - Input bias resistor; sets base current for logic-compatible drive with 3.3 V/5 V microcontrollers. |
| R2/R1 | 1.0 (0.8–1.2) - Emitter feedback ratio; ensures stable saturation and prevents thermal runaway during operation. |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss in high-duty-cycle switching. |
| hFE | ≥80 at VCE = 5 V, IC = 5 mA - DC current gain guarantees reliable switching with minimal drive current overhead. |
| fT | 230 MHz - Transition frequency of internal transistor; supports fast edge rates in digital control paths. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, FR4 PCB compatible footprint per Fig. 11 and Fig. 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connects to MCU GPIO or logic signal; internally tied to R1 top and R2 top; requires no external pull-up/down. |
| 2 | Ground (emitter node) | Common reference for both R1 and R2; serves as return path for input and output currents; must be low-impedance. |
| 3 | Output (collector node) | Switches load between VCC and this pin; supports up to 100 mA sink current with <150 mV drop at rated load. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1 + R2 bias network | Eliminates 2 external resistors; reduces BOM count and PCB area by ~2.5 mm² per instance. |
| AEC-Q101 qualification | Validated for automotive under stress conditions including HTOL, TC, HTRB, and ESD (HBM >2 kV); supports 15-year vehicle life. |
| Logic-level compatible thresholds | VI(on) = 1.6 V typ and VI(off) = 1.2 V typ enable direct interface with 3.3 V CMOS outputs without level-shifting. |
| Thermal derating support | Rth(j-a) = 500 K/W on standard FR4; allows 250 mW Ptot at Tamb ≤ 25 °C, with linear derating above. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
|
Use Scenario: Switching 12 V indicator LEDs and small solenoids in door modules and lighting controllers.

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 |
|---|---|---|---|
| PDTC124ET-Q | R1 = 22 kΩ, R2 = 47 kΩ → R2/R1 = 2.1 typ; higher input sensitivity but lower noise immunity. | Better suited for weak-drive sources (e.g., open-drain I²C lines); less tolerant of leakage-induced false triggering. | Select when driving from low-current sources where VI(on) < 1.2 V is required. |
| BC847B-Q | Discrete NPN BJT with no integrated resistors; requires external RB and RE; hFE = 200–450 vs. 80–200 for PDTC144ET-Q. | Offers higher gain and lower VCE(sat) but increases BOM count, layout complexity, and calibration risk. | Choose only if precise gain control or sub-100 mV saturation is mandatory and space/cost allow two extra passives. |
Compared with PDTC124ET-Q, PDTC144ET-QVL provides tighter R2/R1 matching (1.0 vs. 2.1) for improved noise margin; compared with BC847B-Q, it trades raw gain for integration, reliability, and AEC-Q101 compliance-critical for automotive production.

FAQ
What is the maximum ambient temperature for continuous operation of PDTC144ET-QVL?
The device supports continuous operation from −65 °C to +150 °C ambient, with total power dissipation derated linearly above 25 °C per the 500 K/W thermal resistance. At 85 °C ambient, maximum allowable Ptot drops to 125 mW to maintain Tj ≤ 150 °C.
Can PDTC144ET-QVL be used in 5 V logic systems without additional components?
Yes-its VI(on) = 1.6 V typ and VI(off) = 1.2 V typ ensure clean switching with standard 5 V TTL/CMOS outputs. No external resistors, level shifters, or pull-ups are needed, as R1 and R2 are fully integrated and temperature-stable.
How does the R2/R1 ratio affect switching behavior in PDTC144ET-QVL?
A ratio of 1.0 ensures symmetrical biasing that stabilizes the base-emitter junction voltage during conduction, minimizing variation in VCE(sat) and preventing thermal runaway. This ratio also defines the device's noise immunity margin against false triggering from coupled transients.
Is PDTC144ET-QVL pin-compatible with BC847B-Q in SOT23 packages?
No-while both use SOT23, PDTC144ET-QVL has input (pin 1), ground (pin 2), and output (pin 3) configuration, whereas BC847B-Q uses emitter (pin 1), base (pin 2), collector (pin 3). Direct replacement requires PCB layout revision and netlist rework.
