Product details
Overview
DCX114EUQ-13R-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, designed for compact logic-level switching and signal conditioning. It features 10 kΩ input bias resistors (R1 = R2), 50 V VCEO/VCEO, ±50 mA output current capability, and AEC-Q101 qualification for automotive use in body control modules and LED drivers.
For engineers reviewing the DCX114EUQ-13R-F datasheet, DCX114EUQ-13R-F pinout, DCX114EUQ-13R-F application, or DCX114EUQ-13R-F equivalent, key selection criteria include verified dual-transistor topology, confirmed 10 kΩ/10 kΩ resistor matching, validated SOT363 thermal derating to 200 mW, and documented IO(on) ≤ 0.3 V at 10 mA load.
Technical Context
This device integrates matched NPN and PNP transistors with integrated base-emitter resistors on a single die, enabling direct TTL/CMOS interface without external biasing. Its complementary configuration supports push-pull output stages and level-shifting circuits where bidirectional current control is required.
The SOT363 package provides six terminals with isolated collector/emitter paths for each transistor and shared resistor networks. Electrical symmetry between sections is confirmed by identical |VCEO| = 50 V, |IO| = 50 mA, and |VCE(sat)| ≤ 0.3 V specifications under matched test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | ±50 V - Supports rail-to-rail operation in 24 V automotive systems with margin for transients. |
| IO | ±50 mA - Sufficient drive strength for small-signal relays, LEDs, and gate control of low-power MOSFETs. |
| VCE(sat) | ≤ ±0.3 V @ IC/IB = 10 mA / 0.5 mA - Minimizes conduction loss in switching applications. |
| R1 / R2 | 10 kΩ / 10 kΩ - Enables direct connection to 3.3 V or 5 V logic outputs without external resistors. |
| PD | 200 mW - Limits maximum continuous power per device; requires thermal-aware PCB layout per J-STD-020 Level 1. |
| hFE | 30 (min) @ IC = ±1 mA, VCE = ±5 V - Confirmed current gain for reliable saturation in digital switching mode. |
| AEC-Q101 | Qualified - Validated for automotive temperature range (−55 °C to +150 °C) and reliability stress testing. |
Pinout & Package
Package: SOT363 - Surface-mount, 6-pin plastic package with 0.65 mm lead pitch, UL 94V-0 rated molding compound, and matte tin-plated leads compliant with MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NPN Emitter (EQ1) | Common emitter node for NPN section; connects to ground or low-side return path. |
| 2 | NPN Base (BQ1) | Input terminal with integrated 10 kΩ resistor to NPN base; accepts logic-level drive. |
| 3 | NPN Collector (CQ1) | Output node for NPN switch; sinks current when active. |
| 4 | PNP Collector (CQ2) | Output node for PNP switch; sources current when active. |
| 5 | PNP Base (BQ2) | Input terminal with integrated 10 kΩ resistor to PNP base; accepts inverted logic-level drive. |
| 6 | PNP Emitter (EQ2) | Common emitter node for PNP section; connects to VCC or high-side supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary NPN+PNP pair | Single-package solution eliminates discrete pairing mismatch and saves board space in H-bridge or level-shift designs. |
| Integrated 10 kΩ bias resistors | Eliminates need for two external base resistors per transistor, reducing BOM count and layout complexity. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per IATF 16949 process controls. |
| SOT363 footprint | Compatible with standard 0.65 mm pitch pick-and-place equipment and reflow profiles for high-yield automated assembly. |
| Green, RoHS-compliant | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb), fully lead-free, meeting EU Directive 2015/863/EU. |

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 |
|---|---|---|---|
| DCX114EU-13R-F | Same silicon, but not AEC-Q101 qualified; lacks PPAP documentation and IATF 16949 manufacturing traceability. | Restricted to non-automotive industrial or consumer use where qualification is not mandated. | Select only if automotive qualification is unnecessary and cost sensitivity outweighs long-term supply assurance. |
| ACX114EUQ-13R-F | Direct replacement per Diodes' NRND notice; identical R1/R2 values, package, and AEC-Q101 status; updated part number reflects product family consolidation. | No functional or application change; maintains full drop-in compatibility in existing designs. | Preferred for new designs due to active status and guaranteed long-term availability. |
Compared with DCX114EUQ-13R-F, DCX114EU-13R-F omits automotive qualification-reducing cost but limiting deployment scope-while ACX114EUQ-13R-F offers identical performance with assured continuity, making it the recommended choice for production programs requiring lifecycle support.

FAQ
Is DCX114EUQ-13R-F pin-compatible with DCX114EU-13R-F?
Yes-both share identical SOT363 pinout, internal schematic, and electrical specifications. The only differences are qualification status (AEC-Q101 for DCX114EUQ-13R-F) and marking code (C13). No PCB or firmware changes are needed for substitution.
What is the maximum operating temperature for DCX114EUQ-13R-F in continuous use?
The device is rated for junction temperatures from −55 °C to +150 °C. At +125 °C ambient, power dissipation must be derated to ≤100 mW per transistor (per Fig. 1 derating curve), requiring appropriate copper area and airflow in the final assembly.
Can DCX114EUQ-13R-F drive a 24 V relay coil directly?
Yes-it supports ±50 mA output current and ±50 V VCEO, sufficient for typical 24 V, 400 Ω (60 mA) relay coils. However, an external flyback diode is mandatory across the coil to suppress inductive kickback exceeding the device's 50 V rating.
Does DCX114EUQ-13R-F require external base resistors?
No-the device integrates 10 kΩ resistors from each base to its respective emitter, enabling direct connection to 3.3 V or 5 V logic outputs. External resistors are unnecessary unless specific gain adjustment or noise filtering is required in the application.
