Product details
Overview
PDTC114EU from Nexperia is an NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with built-in bias resistors R1 = 10 kΩ and R2 = 10 kΩ, 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTC114EU datasheet, PDTC114EU pinout, PDTC114EU application, or PDTC114EU equivalent, this device serves as a space- and cost-optimized replacement for discrete BJT + resistor networks in logic-level interface, IC input control, and low-power load switching circuits.
Technical Context
This RET integrates a monolithic NPN transistor with two precision on-die bias resistors (R1 = 10 kΩ, R2/R1 = 1.0 typ), eliminating external base resistors and reducing PCB footprint. It operates with VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V at defined collector current conditions.
The device delivers hFE ≥ 30 at IC = 5 mA, VCE = 5 V, and achieves VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA, enabling efficient low-voltage digital switching in compact automotive and industrial modules.
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 signal chains. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - Integrated input bias resistor; eliminates need for external pull-up/pull-down components. |
| R2/R1 | 1.0 (0.8–1.2) - Matched internal resistor ratio; ensures stable saturation and predictable turn-on behavior. |
| VCE(sat) | ≤150 mV at IC = 10 mA / IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥30 at VCE = 5 V, IC = 5 mA - DC current gain supports reliable digital on/off operation without marginal drive. |
| fT | 230 MHz - Transition frequency confirms suitability for high-speed digital switching up to ~10–20 MHz edge rates. |
| AEC-Q101 | Qualified - Meets automotive-grade stress test requirements for temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
SOT323 (SC-70) surface-mount plastic package: 1.3 mm × 2.2 mm × 0.95 mm body, 3-lead gull-wing configuration, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts TTL/CMOS logic-level drive directly without external resistor. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for base and collector currents. |
| 3 | Output (collector) | Switched output node; connects to load (e.g., LED anode, relay coil, or downstream IC input). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Reduces bill-of-materials count by two resistors and associated placement steps in digital interface circuits. |
| 100 mA output current rating | Supports direct driving of moderate-current loads such as status LEDs, optocoupler inputs, or small-signal relays. |
| AEC-Q101 qualification | Validates reliability for under-hood and dashboard electronics where thermal cycling and vibration tolerance are critical. |
| SOT323 ultra-small footprint | Enables routing in tight spaces (e.g., sensor modules, infotainment sub-assemblies) while maintaining hand-solderability. |
| VI(on)/VI(off) thresholds | 1.8–2.5 V on-state and 0.8–1.1 V off-state voltages ensure clean logic-level compatibility with 3.3 V and 5 V microcontrollers. |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |
|---|---|
|
Use Scenario: Level-shifting and isolation of 12 V sensor signals into 3.3 V microcontroller GPIO pins. IC Role / Device Role / Timing Role: Digital switch translating high-side sensor outputs to MCU-compatible logic levels with built-in current limiting.

Use Value: Maintains optocoupler CTR stability with ±20 % R1 tolerance and 1.0 R2/R1 ratio, improving long-term signal integrity. |
| Consumer Appliance Status Indicator | Medical Diagnostic Device Signal Conditioning |
|
Use Scenario: Driving multi-color status LEDs on smart home appliance control panels. IC Role / Device Role / Timing Role: Low-power, low-VCE(sat) switch enabling efficient LED current control from MCU GPIO. Use Value: 150 mV saturation voltage reduces power dissipation by >30 % vs. standard BC847 in same 10 mA LED drive configuration. |
Use Scenario: Isolating and conditioning analog sensor enable lines in portable diagnostic equipment. IC Role / Device Role / Timing Role: Noise-immune digital gate controlling power to low-noise amplifiers during standby cycles. Use Value: AEC-Q101 qualification ensures stable operation under medical-grade ESD (±8 kV contact) and temperature extremes (−40 °C to +105 °C). |
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 |
|---|---|---|---|
| BC847B, SOT23 | Discrete NPN BJT requiring external base resistors; no integrated R1/R2 network; hFE = 200–450 (higher gain but less predictable drive). | Requires additional PCB area and assembly steps; suitable only when precise bias tuning or higher gain is needed. | Select BC847B only if variable base current control or gain optimization is required; otherwise PDTC114EU reduces design complexity. |
| PDTA114EU, SOT323 | PNP complement with identical R1/R2 values and package; VECO = 50 V, IO = −100 mA; polarity-reversed functionality. | Used in high-side switching or complementary push-pull stages where emitter-follower sourcing is needed. | Choose PDTA114EU when sourcing current from rail (e.g., active-high enable); PDTC114EU remains optimal for sinking loads. |
Compared with BC847B, PDTC114EU saves board space and assembly cost via integrated biasing, while PDTA114EU offers functional symmetry for complementary designs-neither provides drop-in replacement without circuit topology adjustment.

FAQ
What is the maximum operating temperature for PDTC114EU?
The PDTC114EU has a junction temperature limit of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 625 K/W on FR4 PCB with standard footprint, supporting continuous operation at up to 100 °C ambient when dissipating ≤200 mW.
Can PDTC114EU replace BC847 in existing designs?
Yes, PDTC114EU can replace BC847 in digital switching roles where fixed biasing suffices, but requires schematic and layout updates: pin 1 becomes input (not base), pin 2 is emitter (GND), and pin 3 is collector (load). No external resistors are needed, reducing component count by two per channel.
Is PDTC114EU compatible with lead-free reflow soldering?
Yes, PDTC114EU is qualified for lead-free reflow soldering per J-STD-020. The SOT323 package uses matte tin termination and is rated for peak reflow temperatures up to 260 °C. Wave soldering is not recommended; only reflow is supported per Nexperia's process guidelines.
What does the marking "*09" indicate on PDTC114EU units?
The marking "*09" on PDTC114EU devices consists of a manufacturing site code placeholder (*) followed by "09", which is the standardized Nexperia marking code identifying the PDTC114EU type. This code appears on the top surface of the SOT323 package and aligns with Table 5 in the official datasheet.
