Product details
Overview
PDTA114EU-QX from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, rated for −50 V VCEO, −100 mA output current, with integrated R1 = 10 kΩ and R2 = 10 kΩ bias resistors; used as a digital switch for IC input control and load switching in automotive ECUs.
For engineers reviewing the PDTA114EU-QX datasheet, PDTA114EU-QX pinout, PDTA114EU-QX application, or PDTA114EU-QX equivalent, key selection criteria include guaranteed AEC-Q101 qualification, built-in resistor ratio (R2/R1 = 1.0 ± 0.2), −150 mV VCEsat at −10 mA/−0.5 mA drive, and SC-70 thermal resistance of 625 K/W on FR4 PCB.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 10 kΩ, R2 = 10 kΩ) directly into the die assembly, eliminating external base resistors and enabling direct logic-level interfacing. Its R2/R1 ratio of 1.0 ± 0.2 ensures stable saturation behavior across temperature (−40 °C to +150 °C).
The device operates with guaranteed −50 V collector-emitter breakdown voltage and −100 mA continuous output current, supporting robust switching in 12 V automotive domains. Its −1.8 V typical VI(on) at −10 mA enables reliable turn-on from standard CMOS outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base condition; supports 12 V automotive rail with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor; sets base current for predictable turn-on without external components. |
| R2/R1 | 1.0 ± 0.2 - Matched internal resistor ratio; ensures stable saturation and reduces sensitivity to process variation. |
| VCEsat | −150 mV max at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and self-heating during conduction. |
| VI(on) | −2.5 to −1.8 V - On-state input voltage range; compatible with 3.3 V and 5 V CMOS/TTL logic outputs. |
| Ptot | 200 mW at Tamb ≤ 25 °C - Power dissipation limit on standard FR4 PCB; derates linearly above 25 °C per Fig. 1. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body; optimized for high-density automotive PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signal; no external pull-up/down required. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard; suitable for engine control, body electronics, and ADAS modules. |
| Integrated R1 + R2 | Eliminates two external resistors; reduces BOM count, PCB area, and placement cost by ~0.5 mm² and one pick-and-place operation. |
| Matched R2/R1 ratio | 1.0 ± 0.2 tolerance ensures consistent IC/IB gain across production lots and temperature, improving batch-to-batch reliability. |
| Low VCEsat | ≤ −150 mV at rated current; limits power dissipation to < 1.5 mW at 10 mA, enabling use in thermally constrained modules. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door module PCBs. IC Role / Device Role: PNP digital switch sinking current from loads referenced to battery rail. Use Value: AEC-Q101 qualification and −50 V rating ensure robustness against load-dump transients up to ISO 7637-2 Pulse 5a. |
Use Scenario: Level-shifting and isolating 24 V field signals into 3.3 V microcontroller GPIOs. IC Role / Device Role: Input conditioning switch converting industrial voltage levels to logic-compatible signals. Use Value: Built-in R1/R2 eliminates external bias network, reducing component count and failure points in DIN-rail mounted controllers. |
| Automotive HVAC Control Panel | Consumer Appliance Motor Driver Interface |
Use Scenario: Enabling/disabling fan speed control ICs and display backlight drivers. IC Role / Device Role: Logic-controlled enable switch for downstream power stages. Use Value: −1.8 V typical VI(on) allows direct drive from MCU GPIOs without level shifters, cutting BOM cost by $0.015/unit. |
Use Scenario: Driving gate of N-channel MOSFETs in small appliance motor H-bridge pre-drivers. IC Role / Device Role: High-side logic interface translating MCU outputs to MOSFET gate control signals. Use Value: 100 mA output current supports fast MOSFET turn-on with < 100 ns propagation delay, improving efficiency in 24 V DC motors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EU | NPN complement; same R1/R2 values but opposite polarity; VCEO = +50 V, IO = +100 mA. | Requires high-side load configuration (load between VCC and collector); not drop-in for existing PNP designs. | Select when sourcing current from VCC is preferred or when matching NPN logic families in dual-polarity circuits. |
| BC847B-Q | Discrete PNP BJT without integrated resistors; requires external R1/R2; hFE = 200–450 vs. RET's fixed bias ratio. | Offers higher DC gain and adjustable bias, but increases BOM count, layout area, and calibration effort. | Choose only if variable gain or fine-tuned saturation control is required; otherwise PDTA114EU-QX reduces design complexity. |
Compared with PDTC114EU and BC847B-Q, PDTA114EU-QX delivers guaranteed bias stability, AEC-Q101 compliance out-of-box, and zero external resistor dependency-making it optimal for cost-sensitive, high-reliability automotive digital switching where layout space and qualification time are critical.

FAQ
Is PDTA114EU-QX pin-compatible with standard SOT323 PNP transistors?
No-PDTA114EU-QX uses a dedicated RET pinout: Pin 1 = Input (base), Pin 2 = GND (emitter), Pin 3 = Output (collector). Standard PNP transistors (e.g., BC847) assign Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. Physical fit does not imply functional or electrical compatibility.
What is the maximum ambient temperature for continuous 100 mA operation?
At 100 mA, power dissipation is ~15 mW (100 mA × 150 mV). Using the 200 mW rating at 25 °C and 625 K/W thermal resistance, full-rated current is sustainable up to ~115 °C ambient before derating begins-verified per Figure 1's derating curve on FR4 PCB.
Does PDTA114EU-QX support 1.8 V logic-level drive?
No-its VI(on) range is −2.5 V to −1.8 V, meaning it requires ≥1.8 V magnitude (i.e., ≤ −1.8 V) to guarantee turn-on. A 1.8 V logic high cannot drive it; minimum recommended drive is 3.3 V CMOS with rail-to-rail swing or buffered 5 V TTL.
How does the R2/R1 ratio affect switching performance?
An R2/R1 ratio of 1.0 ± 0.2 ensures the internal feedback resistor stabilizes base current during saturation, reducing dependence on hFE variation and maintaining consistent VCEsat across temperature and process corners-critical for timing-critical digital interfaces.
