Product details
Overview
PDTB114EU-QX from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, rated for −50 V VCEO, −500 mA output current, and ±10 % R2/R1 bias resistor ratio tolerance. It integrates base bias resistors (R1 = 10 kΩ, R2/R1 = 1), simplifies digital switching circuits, and supports automotive-grade operation up to 175 °C junction temperature.
For engineers reviewing the PDTB114EU-QX datasheet, PDTB114EU-QX pinout, PDTB114EU-QX application, or PDTB114EU-QX equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, and direct substitution guidance for BC807-series replacement in load-switching and IC-input control designs.
Technical Context
This RET implements a monolithic PNP bipolar transistor with two integrated precision bias resistors-R1 connected between input (base) and ground, and R2 between base and collector-enabling single-resistor drive logic-level interfacing. Its fixed R2/R1 = 1 ratio ensures predictable turn-on/off thresholds across temperature.
Designed for automotive applications per AEC-Q101, it operates reliably from −55 °C to +175 °C ambient, with VI(on) = −1 to −2.2 V at IC = −20 mA and VI(off) = −0.6 to −1.5 V at IC = −100 µA, supporting robust noise-immune digital switching in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with open base; defines high-side switch blocking capability. |
| IO | −500 mA - Continuous DC output current rating; supports medium-power load switching without external heatsinking. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current magnitude for logic-driven saturation. |
| R2/R1 | 1.0 (0.9–1.1) - Precision resistor ratio; ensures stable current gain and consistent switching thresholds. |
| VCE(sat) | −100 mV @ IC = −50 mA, IB = −2.5 mA - Low saturation voltage minimizes conduction loss in power-efficient switching. |
| fT | 140 MHz - Transition frequency of internal transistor; supports fast edge rates in digital interface applications. |
| Tj(max) | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
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, FR4 PCB compatible with reflow and wave soldering footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic-level signal entry point; internally connected to R1 and R2; requires no external base resistor. |
| 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; connects to load; internally referenced to R2 for feedback biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates 2 external resistors; reduces BOM count and layout area in digital interface circuits. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| ±10 % R2/R1 tolerance | Ensures consistent IC/IB ratio across production lots, improving batch-to-batch switching predictability. |
| 175 °C maximum junction temperature | Enables deployment in engine control modules and powertrain ECUs without thermal derating penalties. |
| Low VCE(sat) (−100 mV) | Reduces power dissipation during on-state operation, critical for thermally constrained SOT323 footprint. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |
|---|---|
Use Scenario: Driving LED indicators and small solenoids in door module PCBs. IC Role / Device Role / Timing Role: High-side PNP switch controlling 12 V loads from 3.3 V/5 V microcontroller GPIO.

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 |
|---|---|---|---|
| BC807-40 | Discrete PNP BJT without built-in resistors; requires external R1/R2; hFE = 250–600 vs. RET's fixed bias ratio. | Higher design flexibility but increases component count and layout complexity; not AEC-Q101 qualified. | Select when precise hFE tuning or non-standard R2/R1 ratios are required; avoid in space-constrained or automotive designs. |
| PDTA114EU-Q | N-channel counterpart with identical package, R1/R2 values, and AEC-Q101 rating; complementary device for push-pull configurations. | Used in dual-drive circuits (e.g., half-bridge gate drivers); shares same footprint and thermal profile. | Choose for symmetric NPN/PNP pair implementation where matched thermal and timing behavior is essential. |
Compared with BC807-40 and PDTA114EU-Q, the PDTB114EU-QX provides plug-and-play digital switching with guaranteed resistor matching and automotive qualification-reducing validation effort and PCB area versus discrete solutions, while enabling complementary pairing without footprint mismatch.

FAQ
What is the maximum continuous power dissipation for PDTB114EU-QX on a standard FR4 PCB?
The PDTB114EU-QX delivers 425 mW total power dissipation when mounted on a 4-layer FR4 PCB with tin-plated copper and standard footprint. This rating assumes Tamb ≤ 25 °C and accounts for improved thermal conduction versus single-sided boards (300 mW). Derating begins linearly above 25 °C ambient per the published power derating curve.
Does PDTB114EU-QX require external base resistors for microcontroller GPIO driving?
No. The device integrates R1 = 10 kΩ and R2 = 10 kΩ (R2/R1 = 1) internally, allowing direct connection to 3.3 V or 5 V logic outputs. VI(on) ranges from −1 V to −2.2 V at IC = −20 mA, ensuring reliable turn-on with standard CMOS/TTL output levels without additional components.
How does the AEC-Q101 qualification impact design reuse in non-automotive applications?
AEC-Q101 qualification confirms robustness against temperature cycling, humidity, mechanical shock, and ESD-making the PDTB114EU-QX suitable for demanding industrial, medical, and aerospace applications where reliability exceeds commercial-grade requirements. No redesign is needed when migrating from automotive to these sectors.
Can PDTB114EU-QX replace BC807-40 in existing PCB layouts?
Yes-PDTB114EU-QX uses the same SOT323 (SC-70) footprint and pinout (1 = base/input, 2 = emitter/GND, 3 = collector/output) as BC807-40. However, the integrated bias network eliminates two external resistors, freeing board space and reducing assembly steps without modifying land patterns or routing.
