Product details
Overview
DCX114EU-13R-F 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 VO, matched 10kΩ R1/R2 bias resistors, ±50mA continuous output current per section, and operates across –55°C to +150°C - used in automotive body control modules for LED driver enable/disable sequencing.
For engineers reviewing the DCX114EU-13R-F datasheet, DCX114EU-13R-F pinout, DCX114EU-13R-F application, or DCX114EU-13R-F equivalent, key selection criteria include input voltage thresholds (VI(on) = –1.9 to –3.0V / +1.9 to +3.0V), output saturation voltage (VCE(sat) ≤ ±0.3V), DC current gain (GI = 30 at –5V/–5mA), thermal resistance (RθJA = 625°C/W), and AEC-Q101 qualification status.
Technical Context
This dual-transistor device integrates one NPN and one PNP silicon bipolar junction transistor with integrated base biasing resistors (R1 = R2 = 10kΩ ±30%) on a single die. Each transistor operates independently with separate emitter, base, and collector terminals, enabling push-pull or complementary switching without external bias networks.
The SOT363 package supports automated placement and reflow soldering, with matte tin-plated leads compliant to MIL-STD-202 Method 208. Thermal derating follows a linear 0.32mW/°C reduction above +25°C ambient, capped at 200mW total dissipation under FR-4 board conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO | ±50V - Maximum supply voltage tolerance for both NPN and PNP sections, defining rail-to-rail operating range in bidirectional interface circuits. |
| IO | ±50mA - Continuous output current per transistor, sufficient for driving small relays, LEDs, or logic inputs without external amplification. |
| VI(on) | +1.9 to +3.0V / –1.9 to –3.0V - Input voltage threshold at which each transistor enters active conduction, enabling direct TTL/CMOS-level interfacing. |
| VCE(sat) | ≤ ±0.3V - Low saturation voltage ensures minimal power loss and heat generation during switching, critical for thermally sensitive applications. |
| GI | 30 - DC current gain at –5V/–5mA (PNP) and +5V/+5mA (NPN), indicating predictable current amplification for stable digital switching behavior. |
| R1/R2 | 10kΩ ±30% - Integrated bias resistors eliminate need for discrete base resistors, reducing BOM count and layout area in high-density designs. |
| PD | 200mW - Total power dissipation limit at TA = +25°C, requiring thermal management planning when operating near maximum current/voltage. |
Pinout & Package
Package: SOT363 - 6-pin surface-mount plastic package (2.15mm × 2.10mm × 1.00mm), UL 94V-0 rated, moisture sensitivity level 1, weight ≈ 0.006g.

| 2 (BQ1) | NPN Base | Input node for NPN transistor; connects internally to R1 and R2; requires positive-going logic signal for activation. |
| 3 (CQ1) | NPN Collector | Main current-sinking output terminal for NPN section; tied to load return path in low-side switch configurations. |
| 4 (CQ2) | PNP Collector | Main current-sourcing output terminal for PNP section; tied to load supply path in high-side switch configurations. |
| 5 (EQ2) | PNP Emitter | Common emitter reference for PNP transistor; typically connected to VCC or system ground depending on topology. |
| 6 (EQ1) | NPN Emitter | Common emitter reference for NPN transistor; typically connected to ground in standard switching layouts. |
Key Features

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-13R-F | R1/R2 = 47kΩ instead of 10kΩ; higher input impedance reduces drive current requirement but increases VI(on) threshold. | Better suited for low-power microcontroller outputs with limited sourcing/sinking capability (e.g., 3.3V ARM Cortex-M GPIO). | Select when drive strength is constrained and higher input voltage margin is acceptable. |
| DCX114YU-13R-F | Asymmetric bias (R1 = 10kΩ, R2 = 47kΩ); optimized for mixed-sensitivity input interfaces requiring different turn-on thresholds per polarity. | Used where NPN and PNP sections serve distinct functions - e.g., NPN for fast turn-off, PNP for slow turn-on in soft-start circuits. | Choose for asymmetric switching timing requirements or differential input conditioning. |
Compared with DCX114EU-13R-F, DCX144EU-13R-F offers higher input impedance at the cost of reduced noise immunity, while DCX114YU-13R-F provides tailored asymmetry for specialized timing control - neither matches the balanced 10kΩ bias and 30 GI gain profile required for general-purpose logic-level complementation.

FAQ
What is the maximum allowable junction temperature for DCX114EU-13R-F?
The absolute maximum junction temperature is +150°C, consistent with its –55°C to +150°C operating range. At ambient temperatures above +25°C, power dissipation must be linearly derated at 0.32mW/°C per the RθJA = 625°C/W rating, with total package dissipation not exceeding 200mW on FR-4 board with minimum pad layout.
Can DCX114EU-13R-F replace discrete transistor-resistor combinations in existing designs?
Yes - it directly substitutes two matched transistors plus four bias resistors (two per transistor). Pin compatibility with SOT363 footprint allows drop-in replacement if layout accommodates the 6-pin configuration and thermal constraints are verified, especially given its 200mW power limit and ±50mA output capability.
Is DCX114EU-13R-F qualified for automotive use?
Yes - it is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Its "Green" halogen-free construction, extended temperature range (–55°C to +150°C), and validated reliability testing meet automotive body electronics requirements per Diodes' product definitions.
How does the 10kΩ bias resistor tolerance affect circuit performance?
The ±30% tolerance on R1 and R2 impacts input current (IL = 0.88mA at ±5V) and VI(on) threshold consistency. In practice, this results in ±0.3V variation in turn-on voltage across production lots, requiring design margin in logic-level compatibility checks but remaining within standard TTL/CMOS thresholds.
