Product details
Overview
DCX114EUQ-13-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363 package, featuring integrated 10kΩ base resistors (R1 = R2 = 10kΩ), 50V VCEO/VCEO, ±50mA continuous output current, and AEC-Q101 qualification for automotive use. It functions as a dual-channel logic-level switch in compact space-constrained PCBs for signal routing and load control.
For engineers reviewing the DCX114EUQ-13-F datasheet, DCX114EUQ-13-F pinout, DCX114EUQ-13-F application, or DCX114EUQ-13-F equivalent, key selection criteria include verified input threshold voltage (VI(on) = ±1.9–3.0V at IO), guaranteed saturation voltage (VCE(sat) ≤ ±0.3V), complementary polarity pairing, and automotive-grade reliability with PPAP capability.
Technical Context
This device integrates two monolithic transistors - one NPN and one PNP - each with matched on-chip bias resistors (R1 = R2 = 10kΩ) to enable direct TTL/CMOS logic interface without external base drive components. The complementary configuration supports push-pull output stages and bidirectional signal switching.
It operates across –55°C to +150°C with thermal resistance θJA = 625°C/W on FR-4 board, and delivers hFE = 30 (NPN) and hFE = 30 (PNP) at IC = ±1mA, VCE = ±5V. Input voltage thresholds are symmetric: VI(on) = +1.9–3.0V (NPN), –1.9––3.0V (PNP) at VO = ±0.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO / VCEO | ±50V - Supports rail-to-rail switching in 24V automotive and industrial control systems without breakdown risk. |
| IO (continuous) | ±50mA - Enables direct driving of small relays, LEDs, or logic inputs without external amplification. |
| VCE(sat) | ≤ ±0.3V at IC/IB = ±10mA/±0.5mA - Minimizes power loss and heat generation in high-duty-cycle switching. |
| R1 / R2 | 10kΩ ±30% - Provides standardized, temperature-stable base biasing compatible with 3.3V/5V logic families. |
| PD (total) | 200mW - Limits thermal footprint in dense SMT layouts; derates linearly above +25°C ambient. |
| hFE | 30 (NPN & PNP) at IC = ±1mA - Ensures predictable current gain for stable switching margins in feedback-free circuits. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount plastic package with 0.65mm lead pitch, UL 94V-0 rated molding compound, and matte tin-plated terminals compliant with MIL-STD-202.

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-13-F | Direct replacement with identical R1/R2 = 10kΩ, same SOT363 package, and updated manufacturing process; NRND status lifted. | Same automotive qualification and electrical specs; preferred for new designs due to active production status. | Select ACX114EUQ-13-F for new designs to ensure long-term supply continuity and access to latest wafer fab revisions. |
| DCX114EU-13R-F | Same die and bias values but marked as "Active" (not NRND); uses identical SOT363 package and C13 top-side marking. | Functionally identical but lacks explicit AEC-Q101 documentation in public ordering info; suitable for non-automotive industrial use. | Choose DCX114EU-13R-F only if AEC-Q101 certification is not required and legacy part number preference applies. |
Compared with DCX114EUQ-13-F, ACX114EUQ-13-F offers assured supply and updated process control, while DCX114EU-13R-F provides identical performance without automotive documentation - making the ACX variant optimal for new automotive designs and the DCX variant acceptable for cost-sensitive industrial applications where qualification traceability is secondary.

FAQ
Is DCX114EUQ-13-F pin-compatible with DCX114EU-13R-F?
Yes - both share identical SOT363 pinout, internal schematic, and electrical specifications. The only differences are product status (NRND vs. Active) and marking code (C13). No PCB redesign is needed when migrating from DCX114EUQ-13-F to DCX114EU-13R-F, though AEC-Q101 documentation may not be publicly available for the latter.
What is the maximum operating temperature for continuous use?
The device is rated for junction temperatures from –55°C to +150°C. At ambient temperatures up to +85°C, it sustains full ±50mA output with proper PCB copper pour; above that, derating follows the 625°C/W thermal resistance curve - e.g., at +100°C ambient, max power drops to ~120mW per transistor.
Can DCX114EUQ-13-F drive a 12V relay coil drawing 40mA?
Yes - its ±50mA continuous output rating exceeds the 40mA requirement, and VCE(sat) ≤ ±0.3V ensures minimal voltage drop and power loss (≤12mW). For 12V coils, connect the PNP emitter to +12V, collector to coil, and coil return to ground; drive base pin 5 with MCU low signal.
Why does the datasheet list DCX114EUQ-13-F as NRND?
NRND ("Not Recommended for New Design") indicates Diodes has transitioned this variant to an updated replacement - ACX114EUQ-13-F - with improved process control and assured long-term supply. While DCX114EUQ-13-F remains available, new designs should adopt the ACX version to avoid future obsolescence risks.
