Product details
Overview
DCX114EUQ-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, designed for level-shifting and digital switching in automotive and industrial control circuits. It features 50V VO, matched 10kΩ R1/R2 bias resistors, ±50mA output current capability, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the DCX114EUQ-7-F datasheet, DCX114EUQ-7-F pinout, DCX114EUQ-7-F application, or DCX114EUQ-7-F equivalent, this device supports compact dual-transistor logic interface design with integrated biasing, low saturation voltage, and verified thermal performance up to +150°C ambient.
Technical Context
This dual pre-biased transistor integrates one NPN and one PNP silicon epitaxial planar transistor with on-die base-emitter resistors (R1 = R2 = 10kΩ ±30%) to eliminate external bias components. Each transistor operates independently with separate input and output terminals, supporting push-pull or complementary switching topologies.
The device delivers VCE(sat) ≤ 0.3V at IC/IB = 10mA/0.5mA (NPN) and ≤ –0.3V at IC/IB = –10mA/–0.5mA (PNP), with DC current gain (GI) of 30 at VO = ±5V and IO = ±5mA. Thermal resistance θJA is 625°C/W on FR-4 PCB with minimum pad layout.
Key Specifications

| VO (Supply Voltage) | ±50V - Enables operation across wide rail ranges including 12V/24V automotive systems and industrial 48V buses. |
| R1, R2 (Bias Resistors) | 10kΩ ±30% - Integrated matching resistors reduce BOM count and layout area for digital input conditioning. |
| IO (Output Current) | ±50mA - Sufficient drive strength for LED indicators, small relays, and gate driving of low-side MOSFETs. |
| VCE(sat) | ≤ ±0.3V at ±10mA/±0.5mA - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| PD (Power Dissipation) | 200mW - Supports continuous operation at ambient temperatures up to +85°C with standard PCB layout. |
| TJ, TSTG | –55°C to +150°C - Validated for under-hood automotive environments and extended industrial temperature ranges. |
| AEC-Q101 Qualified | Yes - Certified for automotive applications requiring PPAP documentation and IATF 16949 manufacturing controls. |

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 |
|---|---|---|---|
| ACX114EUQ-7-F | Direct replacement; same electrical specs and pinout, but updated part marking and production status (Active vs NRND). | Identical functional use in new designs; replaces DCX114EUQ-7-F where long-term supply continuity is required. | Select ACX114EUQ-7-F for new designs to ensure availability beyond DCX114EUQ-7-F's NRND lifecycle phase. |
| DCX114EU-7-F | No Q-suffix; non-automotive grade, not AEC-Q101 qualified, same R1/R2 values and SOT363 package. | Suitable for commercial/industrial applications only; lacks PPAP documentation and automotive change control. | Choose DCX114EU-7-F when AEC-Q101 compliance is unnecessary and cost optimization is prioritized. |
Compared with DCX114EUQ-7-F, ACX114EUQ-7-F offers identical performance with assured long-term supply, while DCX114EU-7-F provides cost savings in non-automotive contexts but omits automotive qualification and traceability.

FAQ
Is DCX114EUQ-7-F still recommended for new designs?
No - DCX114EUQ-7-F is marked NRND (Not Recommended for New Design) per Diodes' ordering information. The official replacement is ACX114EUQ-7-F, which maintains identical electrical characteristics, pinout, and packaging while ensuring ongoing production and automotive qualification support.
What is the maximum continuous output current per transistor?
The absolute maximum rated output current is ±50mA per transistor (NPN and PNP sections separately), with peak current capability up to ±100mA. Derating applies above +25°C ambient: power dissipation must not exceed 200mW total, and junction temperature must remain below +150°C.
Can DCX114EUQ-7-F replace discrete transistors in existing designs?
Yes - it directly substitutes two discrete transistors plus four external bias resistors in complementary switching configurations. Pin compatibility with SOT363-layout footprints and matched R1/R2 values simplify drop-in integration, though layout review is required to confirm thermal pad clearance and trace routing.
Does DCX114EUQ-7-F support 3.3V logic interfacing?
Yes - its VI(on) range of ±1.9V to ±3.0V (at IO = ±10mA) ensures reliable turn-on from 3.3V CMOS outputs. Input current is ±0.88mA at VI = ±3.3V, compatible with standard MCU GPIO drive capability without additional buffering.
