Product details
Overview
DCX114EU-7 from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, designed for compact logic-level switching and signal inversion in space-constrained PCBs. It features 50V VCEO, matched 10kΩ input bias resistors (R1 = R2), 50mA continuous output current per channel, and ±0.3V VCE(sat) at IC/IB = 10mA/0.5mA - enabling direct interface with 3.3V/5V microcontrollers in level-shifting and LED driver circuits.
For engineers reviewing the DCX114EU-7 datasheet, DCX114EU-7 pinout, DCX114EU-7 application, or DCX114EU-7 equivalent, key selection criteria include its dual-channel complementary configuration, guaranteed ±1.9V to ±3.0V VI(on) threshold range, 30 dB current gain (GI = 30) at VO = ±5V, and AEC-Q101 qualification for automotive body electronics.
Technical Context
This device integrates two monolithic silicon transistors - one NPN and one PNP - with integrated base-emitter resistors (R1 = R2 = 10kΩ ±30%) on a single die. Each channel operates independently with symmetrical absolute maximum ratings: ±50V VCEO, ±100mA ICM, and ±50mA IO continuous.
The pre-biased architecture eliminates external base resistors, reduces component count, and ensures consistent turn-on behavior across temperature (−55°C to +150°C). Input voltage thresholds (VI(on) = ±1.9V to ±3.0V) and low saturation voltage (±0.1V to ±0.3V) support reliable switching in 3.3V/5V digital systems without additional level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | ±50V - supports rail-to-rail operation in 24V industrial control and 12V automotive subsystems |
| IO (continuous) | ±50mA per channel - drives medium-current loads like small relays, LEDs, or gate inputs without external buffering |
| VCE(sat) | ±0.1V to ±0.3V at IO/IL = ±10mA/±0.5mA - minimizes power loss and self-heating in high-duty-cycle switching |
| GI (DC current gain) | 30 at VO = ±5V, IO = ±5mA - provides predictable current amplification for logic-driven switching with stable gain over temperature |
| R1 / R2 | 10kΩ ±30% - enables direct connection to MCU GPIOs while limiting base current to ≤0.88mA at ±5V input |
| PD | 200mW total - allows dual-channel operation within thermal limits on standard FR-4 PCBs with minimal copper area |
| TJ range | −55°C to +150°C - qualified for under-hood automotive, industrial motor control, and outdoor IoT applications |

Applications
| Automotive Body Control Module | Industrial PLC Output Stage |
|---|---|
Use Scenario: Driving door lock actuators and interior lighting via 3.3V microcontroller outputs. IC Role / Device Role / Timing Role: Dual-channel level-shifting switch - NPN sinks load current to ground; PNP sources current from 12V rail. Use Value: Eliminates need for separate NPN/PNP drivers and four base resistors, reducing BOM count and layout complexity in tight ECU spaces. |
Use Scenario: Interfacing 24V DC solenoid valves and indicator LEDs with 5V FPGA I/O banks. IC Role / Device Role / Timing Role: Logic-compatible output buffer - translates TTL/CMOS signals into higher-voltage, higher-current drive capability. Use Value: Enables direct 5V logic control of 24V loads with <0.3V dropout, minimizing heat generation and simplifying isolation design. |
| USB-C Power Delivery Sequencing | Smart Home Sensor Hub |
Use Scenario: Enabling/disabling VBUS and CC line pull-up/down resistors during USB PD negotiation. IC Role / Device Role / Timing Role: Precision-controlled bilateral switch - coordinates timing-critical enable/disable sequences between power rails and data lines. Use Value: Provides matched turn-on characteristics (±1.9–3.0V VI(on)) and fast response for sub-millisecond sequencing without cross-conduction risk. |
Use Scenario: Managing multi-sensor power gating (PIR, ambient light, humidity) in battery-powered hubs. IC Role / Device Role / Timing Role: Low-quiescent-current load switch - controls sensor supply rails using MCU GPIOs with minimal leakage (<0.5μA off-state). Use Value: Achieves <0.5μA IO(off) at VCC = ±50V, extending battery life in always-on edge devices while maintaining fast wake-up response. |
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 |
|---|---|---|---|
| DCX144EU-7-F | R1 = R2 = 47kΩ ±30%; lower input current (0.18mA at ±5V); GI = 68 at ±5V/±5mA | Better suited for high-impedance MCU outputs or battery-sensitive designs where base current must be minimized | Select when driving from weak GPIOs or optimizing for ultra-low standby power - not drop-in due to higher VI(on) threshold |
| DCX123JU-7-F | R1 = 2.2kΩ, R2 = 47kΩ; asymmetric biasing; IO = ±100mA; GI = 80 at ±5V/±10mA | Optimized for high-current NPN switching with PNP logic-level control - e.g., motor direction control | Choose for asymmetrical load requirements where NPN handles heavier loads than PNP; requires revalidation of input drive strength |
Compared with DCX114EU-7, DCX144EU-7 offers lower base current but reduced gain and higher VI(on), while DCX123JU-7 provides higher current capability with unbalanced resistor values - making DCX114EU-7 optimal for symmetric, medium-current logic interfacing where simplicity and matching matter most.

FAQ
What is the maximum operating junction temperature for DCX114EU-7?
The absolute maximum junction temperature is +150°C, with continuous operation supported from −55°C to +150°C. Derating begins at +25°C ambient, with power dissipation limited to 200mW at TA = +25°C and falling linearly to zero at +150°C per the 625°C/W RθJA curve.
Can DCX114EU-7 drive a 12V relay coil directly?
Yes - with a 12V supply applied to EQ2 (PNP emitter), the PNP channel can source up to 50mA continuously. For typical 12V/400Ω relay coils drawing 30mA, VCE(sat) remains ≤−0.3V, ensuring ≥11.7V across the coil and reliable actuation without external buffering.
Is DCX114EU-7 pin-compatible with other DCX-series variants?
No - all DCX variants share the SOT363 footprint and pin numbering, but internal resistor values and channel configurations differ. DCX114EU-7 has matched 10kΩ resistors; substituting DCX144EU-7 (47kΩ) or DCX123JU-7 (2.2kΩ/47kΩ) requires circuit revalidation due to altered input current and gain.
Does DCX114EU-7 require external decoupling capacitors?
No dedicated decoupling is required for basic switching operation. However, a 100nF ceramic capacitor placed near the VCC (EQ2) and ground (EQ1) pins is recommended for noise immunity in electrically noisy environments such as automotive or industrial motor control applications.
