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.

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.
