Product details
Overview
DCX114YUQ-13-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, integrating 10kΩ and 47kΩ bias resistors, rated for 50V VO, 70mA NPN / −70mA PNP output current, and AEC-Q101 qualified for automotive signal switching applications such as LED driver control and microcontroller I/O buffering.
For engineers reviewing the DCX114YUQ-13-F datasheet, DCX114YUQ-13-F pinout, DCX114YUQ-13-F application, or DCX114YUQ-13-F equivalent, key selection criteria include input threshold voltage (VI(on) = 1.4V/−1.4V), on-state output voltage (VO(on) = 0.1–0.3V), DC current gain (GI = 68–80), and thermal resistance (RθJA = 625°C/W) under SOT363 mounting conditions.
Technical Context
This dual-transistor device integrates matched NPN and PNP silicon transistors with integrated base bias networks-R1 = 10kΩ and R2 = 47kΩ-enabling single-pin logic-level drive without external resistors. It operates across −55°C to +150°C and supports bidirectional switching with symmetrical ±50V breakdown ratings.
The NPN section delivers 70mA continuous output at VCE(sat) ≤ 0.3V (IC/IB = 5mA/0.25mA), while the PNP section provides −70mA with VCE(sat) ≥ −0.3V under identical conditions; both exhibit fT = 250MHz and hFE = 100–600, supporting medium-speed digital and analog interface functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO Rating | ±50V supply voltage - enables use in 24V automotive and industrial bus interfaces without level-shifting. |
| IO (NPN/PNP) | +70mA / −70mA - sufficient to directly drive LEDs, small relays, or logic inputs without external amplification. |
| VI(on) | +1.4V / −1.4V at IO = 1mA - compatible with 1.8V–3.3V MCU GPIOs for low-threshold activation. |
| VO(on) | +0.1–0.3V / −0.1–−0.3V at IO/IL = 5mA/0.25mA - minimizes power loss and heat generation in high-duty-cycle switching. |
| GI (DC Current Gain) | 68–80 at VO = ±5V, IO = ±10mA - ensures stable saturation with predictable base drive requirements. |
| RθJA | 625°C/W - requires minimal PCB copper area for thermal management in space-constrained SOT363 layouts. |
| AEC-Q101 Qualified | Validated for automotive electronics per IATF 16949 manufacturing - supports PPAP submission and functional safety-critical subsystems. |
Pinout & Package
Package: SOT363 - 6-pin surface-mount plastic package (2.15mm × 2.10mm × 0.95mm), lead-free, halogen-free, moisture sensitivity level 1, matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (BQ2) | PNP Base Input | Input node for PNP transistor; connects internally to R1 (10kΩ) and R2 (47kΩ) network. |
| 2 (BQ1) | NPN Base Input | Input node for NPN transistor; shares same resistor network topology as Pin 1 but opposite polarity. |
| 3 (CQ1) | NPN Collector Output | Active-high switch output; sinks current when driven via Pin 2. |
| 4 (CQ2) | PNP Collector Output | Active-low switch output; sources current when driven via Pin 1. |
| 5 (EQ2) | PNP Emitter | Common emitter connection for PNP section; typically tied to VCC rail in high-side switching. |
| 6 (EQ1) | NPN Emitter | Common emitter connection for NPN section; typically grounded in low-side switching. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary NPN+PNP Pair | Single SOT363 package replaces two discrete transistors and four bias resistors - reduces BOM count and layout area by >60%. |
| Integrated Bias Network | R1 = 10kΩ, R2 = 47kΩ with ±30% R1 tolerance and ±20% R2/R1 ratio - eliminates manual resistor selection and matching errors. |
| Automotive Qualification | AEC-Q101 qualified, PPAP-capable, manufactured in IATF 16949 facilities - meets Tier-1 supplier requirements for engine control, body electronics, and ADAS modules. |
| Green Compliance | Fully RoHS 3 compliant, halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - satisfies EU ELV and global environmental mandates. |
| Thermal Performance | 200mW total package power dissipation (150mW per element max) - supports continuous operation at ambient up to +85°C with standard FR-4 layout. |
Applications
| LED Driver Interface | Microcontroller I/O Buffering |
|---|---|
|
Use Scenario: Driving multiplexed automotive interior LEDs from 3.3V MCU outputs with common-anode configuration. IC Role / Device Role / Timing Role: NPN section switches LED cathodes to ground; PNP section sources current to common anode rail during active scan periods. Use Value: Eliminates need for external pull-up/pull-down resistors and reduces GPIO loading - improves timing margin and reduces firmware overhead. |
Use Scenario: Level-shifting and current boosting between mixed-voltage logic domains (e.g., 1.8V sensor interface to 5V actuator controller). IC Role / Device Role / Timing Role: Acts as bidirectional digital buffer with fast turn-on (tON < 100ns typical) and rail-to-rail output swing. Use Value: Maintains signal integrity across voltage domains without introducing propagation delay skew or shoot-through risk. |
| Automotive Door Module Switching | Industrial Sensor Signal Conditioning |
|
Use Scenario: Controlling window lift motors and mirror actuators in door control units using PWM signals from body control module. IC Role / Device Role / Timing Role: High-side (PNP) and low-side (NPN) drivers operate in complementary mode to enable H-bridge-like bidirectional motor control. Use Value: Supports 10kHz PWM operation with <0.3V saturation drop - minimizes power loss and thermal stress in sealed module enclosures. |
Use Scenario: Isolating and conditioning analog sensor outputs (e.g., thermistor, potentiometer) before ADC sampling in PLC input modules. IC Role / Device Role / Timing Role: Used as active current source/sink to linearize sensor response and reject noise on long cable runs. Use Value: Delivers stable 70mA sourcing/sinking capability with <1% gain variation over −40°C to +125°C - improves measurement repeatability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DCX114YU-13-F | No Q suffix; non-automotive grade, not AEC-Q101 qualified, same R1/R2 values and electrical specs. | Restricted to commercial/industrial use only; unsuitable for automotive PPAP or safety-critical systems. | Select when AEC-Q101 compliance is unnecessary and cost optimization is prioritized. |
| ACX114YUQ-13-F | Direct replacement per Diodes' NRND notice; identical pinout, bias values, and performance; updated process with enhanced reliability. | Same automotive qualification and application scope; recommended for new designs per manufacturer guidance. | Preferred for all new automotive designs due to active status and extended lifecycle support. |
Compared with DCX114YUQ-13-F, DCX114YU-13-F lacks automotive qualification and long-term supply assurance, while ACX114YUQ-13-F offers identical functionality with guaranteed availability and improved process robustness - making it the optimal choice for production ramp and safety-critical deployment.

FAQ
Is DCX114YUQ-13-F pin-compatible with DCX114YU-13-F?
Yes - both share identical SOT363 pinout, internal schematic, and electrical specifications. The Q suffix denotes AEC-Q101 qualification and automotive-grade traceability; mechanical and electrical interoperability is fully maintained.
What is the maximum operating temperature for continuous use?
The device is rated for junction temperatures from −55°C to +150°C. For continuous operation at ambient temperatures above +85°C, derating per Figure 1 is required: power dissipation must be reduced linearly from 200mW at +25°C to 0mW at +150°C.
Can DCX114YUQ-13-F drive a 50mA solenoid directly?
Yes - its NPN section supports 70mA continuous output at VCE(sat) ≤ 0.3V, well above 50mA. Ensure VI(on) ≥ 1.4V is met by the driving source and that PCB copper area complies with Diodes' recommended pad layout for thermal management.
Why does the datasheet list DCX114YUQ-13-F as NRND?
Diodes has designated DCX114YUQ-13-F as "Not Recommended for New Design" in favor of ACX114YUQ-13-F, which uses an enhanced manufacturing process. Existing designs may continue using DCX114YUQ-13-F, but new projects should adopt the ACX variant for assured long-term supply.
