Product details
Overview
PDTA114EU from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, rated for −50 V VCEO, −100 mA IO, with integrated R1 = 10 kΩ and R2 = 10 kΩ bias resistors. It functions as a digitally controlled switch for IC input driving and low-power load switching in automotive and industrial digital circuits.
For engineers reviewing the PDTA114EU datasheet, PDTA114EU pinout, PDTA114EU application, or PDTA114EU equivalent, this part serves as a drop-in replacement for BC847-based digital switch designs-offering simplified biasing, reduced BOM count, and validated thermal performance up to 150 °C junction temperature.
Technical Context
The PDTA114EU integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 connected between base and input terminal, and R2 between base and emitter (ground). This configuration enables single-resistor external drive while ensuring predictable turn-on/off thresholds across temperature.
Its fixed R2/R1 ratio of 1.0 ±0.2 ensures stable current gain control under varying ambient conditions (−40 °C to +150 °C), and its −150 mV VCE(sat) at IC = −10 mA / IB = −0.5 mA confirms low-loss switching capability in logic-level interfacing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in high-side switch configurations. |
| IO | −100 mA - Continuous output current rating; supports driving moderate digital loads such as LED indicators or small relays. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current magnitude and determines required drive voltage for reliable saturation. |
| VCE(sat) | −150 mV max at IC = −10 mA - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| hFE | 30 min at VCE = −5 V, IC = −5 mA - DC current gain sufficient for digital switching where precise analog amplification is not required. |
| Tj max | 150 °C - Maximum junction temperature; enables use in under-hood automotive modules and industrial enclosures without forced cooling. |
Pinout & Package
Package: SOT323 (SC-70), 3-pin surface-mount plastic package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch. Optimized for reflow soldering per IPC-J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Connected internally to R1; accepts TTL/CMOS-compatible logic-level signals to control transistor conduction. |
| 2 (GND) | Ground (emitter node) | Emitter terminal tied to system ground; provides return path for load current and reference for R2 bias network. |
| 3 (O) | Output (collector node) | Switched high-side output; connects to load anode when active, enabling sourcing of current to grounded loads. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | R1 = 10 kΩ and R2 = 10 kΩ eliminate need for external pull-up/down components, reducing PCB area by ≥20% vs discrete BJT + resistors. |
| Low VCE(sat) | ≤ −150 mV at IC = −10 mA ensures <1.5 mW conduction loss, critical for battery-powered and thermally constrained systems. |
| Wide operating temperature | Rated from −65 °C to +150 °C ambient enables deployment in engine control units, motor drives, and industrial PLC I/O modules. |
| Standard SC-70 footprint | Compatible with automated pick-and-place equipment and standard reflow profiles, lowering assembly cost versus larger packages like SOT23. |
Applications
| Automotive Body Control Module | Industrial Digital I/O Interface |
|---|---|
Use Scenario: Driving LED status indicators and small solenoid valves in door module PCBs. IC Role / Device Role / Timing Role: High-side digital switch controlling 12 V loads using 3.3 V microcontroller GPIO.

IC Role / Device Role / Timing Role: Controlled enable switch activated by system supervisor IC. Use Value: Built-in resistor ratio ensures consistent turn-on threshold across production lots, eliminating calibration steps. |

Use Value: Low Cc (≤3 pF) and high fT (180 MHz typical) suppress coupling of fast digital edges into analog signal paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EU | NPN complement with identical R1/R2 values and package; VCEO = +50 V, IO = +100 mA. | Suitable for low-side switching only; requires inverted logic drive and ground-referenced loads. | Select when load must be connected to VCC and switched to ground, or when matching NPN logic families. |
| BC847B | Discrete PNP BJT without integrated resistors; hFE = 200–450, VCEO = −45 V, no built-in bias network. | Requires external base resistor network; higher design complexity and layout sensitivity to noise. | Choose only if precise analog gain control or higher voltage margin (>−50 V) is required; otherwise RET offers superior integration. |
Compared with PDTC114EU and BC847B, PDTA114EU delivers plug-and-play digital switching with guaranteed biasing, lower assembly cost, and smaller footprint-making it optimal for high-volume, space-constrained digital interface applications where functional simplicity outweighs fine-grained analog tuning.

FAQ
What is the maximum allowable input voltage at Pin 1 (I)?
The absolute maximum input voltage at Pin 1 is −40 V to +10 V, per the VI limiting values table. Exceeding −40 V risks damaging the internal R1 resistor or base-emitter junction. For robust 3.3 V or 5 V logic interfacing, no external clamping is needed due to the built-in resistor network and specified VI(on)/VI(off) thresholds.
Can PDTA114EU drive a 24 V relay coil directly?
No-it is rated for −50 V VCEO but designed for ≤100 mA continuous output. A typical 24 V relay coil draws >150 mA and may induce inductive kickback exceeding safe operating area limits. Use PDTA114EU only with loads ≤100 mA and add flyback diode protection if driving inductive loads.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 ±0.2 ensures the base is pulled toward emitter potential when input is inactive, guaranteeing clean turn-off even with leakage currents. This ratio stabilizes the effective base current under temperature variation, maintaining consistent VI(off) (−1.1 to −0.8 V) and preventing unintended conduction in noisy environments.
Is PDTA114EU qualified for automotive applications?
No-the datasheet explicitly states "Non-automotive qualified products" in Section 15. While rated for −65 °C to +150 °C ambient and used in automotive body modules, it lacks AEC-Q101 qualification, PPAP documentation, or automotive-specific reliability testing. For safety-critical or ASIL-rated systems, select an AEC-Q101 qualified RET variant.
