Product details
Overview
DCX114YUQ-13R-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, featuring integrated 10kΩ and 47kΩ bias resistors, 50V VO, ±70mA output current (NPN), ∓70mA (PNP), and AEC-Q101 qualification for automotive signal switching applications.
For engineers reviewing the DCX114YUQ-13R-F datasheet, DCX114YUQ-13R-F pinout, DCX114YUQ-13R-F application, or DCX114YUQ-13R-F equivalent, key selection criteria include input voltage thresholds (VI(on) = 1.4V / −1.4V), on-state output voltage (VO(on) = 0.1–0.3V / −0.1–−0.3V), DC current gain (GI = 68–80), and thermal derating behavior at elevated ambient temperatures.
Technical Context
This device integrates matched NPN and PNP transistors with monolithic bias resistors (R1 = 10kΩ, R2 = 47kΩ) to enable direct logic-level drive without external base components. It operates across ±50V supply rails and supports bidirectional switching in push-pull or level-shifting configurations.
The complementary topology allows simultaneous control of high-side (PNP) and low-side (NPN) paths with matched turn-on characteristics-VI(on) = +1.4V (NPN) and −1.4V (PNP) at IO = 1mA-and tightly controlled resistor ratio tolerance (±20%) for consistent gain and saturation behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO Rating | ±50V - Enables use in 24V/36V automotive power domains with margin for load dump transients. |
| IO (NPN/PNP) | ±70mA - Supports driving small relays, LEDs, or logic inputs without external current amplification. |
| VI(on) | +1.4V / −1.4V - Compatible with 1.8V–3.3V microcontroller GPIOs for direct interface without level shifters. |
| VO(on) | 0.1–0.3V / −0.1–−0.3V - Ensures low conduction loss and minimal voltage drop in active switching paths. |
| GI (DC Current Gain) | 68–80 @ VO = ±5V, IO = ±10mA - Provides predictable current amplification for stable switching thresholds. |
| R1/R2 | 10kΩ / 47kΩ - Sets base bias for reliable saturation while limiting input current to ≤0.88mA at 5V. |
| PD & RθJA | 200mW / 625°C/W - Requires thermal-aware PCB layout (FR-4, minimum pad area) for sustained operation up to +125°C ambient. |

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 |
|---|---|---|---|

FAQ
Is DCX114YUQ-13R-F pin-compatible with DCX114YU-13R-F?
Yes - both share identical SOT363 pinout, internal schematic, and electrical specifications. The only difference is AEC-Q101 qualification and associated test documentation; no PCB or schematic changes are required for substitution in automotive designs.
What is the maximum operating temperature for continuous DCX114YUQ-13R-F operation?
The device is rated for −55°C to +150°C junction temperature. At +125°C ambient, derated power dissipation is 100mW per transistor (per Fig. 1), requiring FR-4 PCB with minimum recommended copper area to maintain RθJA ≤ 625°C/W.
Can DCX114YUQ-13R-F drive a 100mA relay coil directly?
No - its rated continuous output current is ±70mA. Driving a 100mA coil risks thermal overload and premature failure. Use it to drive a higher-current MOSFET or bipolar transistor stage instead, or select DCX123JUQ (±100mA rated) for direct relay control.
Why does the datasheet list DCX114YUQ-13R-F as NRND?
NRND ("Not Recommended for New Design") indicates Diodes Incorporated has introduced ACX114YUQ-13R-F as the preferred successor. While DCX114YUQ-13R-F remains available and fully supported, new designs should adopt the ACX variant for extended lifecycle assurance and updated manufacturing controls.
