Product details
Overview
ACX114YUQ-13R from Diodes Incorporated is a complementary pre-biased dual transistor in SOT363 package, integrating one NPN and one PNP small-signal transistor with built-in 10 kΩ and 47 kΩ bias resistors. It supports ±50 V VCC, delivers ±100 mA IC(max), features 250 MHz fT, and is AEC-Q101 qualified for automotive signal switching applications.
For engineers reviewing the ACX114YUQ-13R datasheet, ACX114YUQ-13R pinout, ACX114YUQ-13R application, or ACX114YUQ-13R equivalent, key selection criteria include complementary dual topology, integrated resistor ratio tolerance (±20%), VCE(SAT) ≤ 0.3 V at 5 mA/0.25 mA, thermal resistance of 450 °C/W, and automotive-grade reliability under -55 °C to +150 °C operation.
Technical Context
This device implements two monolithic silicon epitaxial planar transistors - one NPN (Q1) and one PNP (Q2) - sharing common emitter terminals (pins 1 and 3), each with dedicated base bias networks (R1/R2 per transistor). The internal resistor configuration enables direct logic-level drive without external bias components.
Each transistor operates independently with separate collector (pins 6 and 4) and base (pins 2 and 5) connections, supporting high-side and low-side switching in compact space-constrained designs. The matched gain-bandwidth (250 MHz typ.) and symmetrical DC current gain (hFE ≥ 80) ensure balanced performance across both polarities under pulsed conditions (≤300 µs, ≤2% duty cycle).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Rating | ±50 V - Supports rail-to-rail signal switching in 24 V automotive and industrial control buses. |
| IC(max) | ±100 mA - Enables driving moderate-current loads such as LED indicators, relay coils, or logic buffers. |
| fT | 250 MHz typ. - Allows use in medium-speed digital interface conditioning and pulse shaping up to ~100 MHz. |
| VCE(SAT) | ≤ 0.3 V at IO/IL = 5 mA/0.25 mA - Minimizes conduction loss and self-heating in always-on or PWM-driven circuits. |
| R1/R2 Ratio Tolerance | ±20% - Ensures predictable input current division and stable switching thresholds across temperature and process variation. |
| PD | 270 mW total - Limits maximum continuous power dissipation on FR4 PCB with minimum pad layout; derates linearly above 25 °C. |
| Operating Temp | -55 °C to +150 °C - Qualified for under-hood automotive environments and industrial motor control enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSBC114YTW | Same SOT363 package, identical R1/R2 values (10 kΩ/47 kΩ), but only NPN+NPN configuration - no PNP element. | Limited to dual-NPN logic buffering; cannot replace ACX114YUQ in push-pull or high-side switching roles. | Select only when complementary polarity is not required and dual low-side drive suffices. |
| EMH11T2R | Includes integrated ESD protection (±8 kV HBM), higher VCEO (60 V), but larger SOT563 package and ±150 mA IC rating. | Better suited for harsh ESD environments (e.g., factory floor I/O), but requires PCB redesign due to different footprint and pinout. | Choose when system-level ESD robustness exceeds ±4 kV and board space allows larger package. |
Compared with NSBC114YTW and EMH11T2R, ACX114YUQ-13R uniquely delivers true complementary NPN+PNP functionality in the smallest standard footprint, optimized for cost-sensitive automotive signal routing where polarity flexibility and AEC-Q101 compliance are mandatory.

FAQ
What is the pin 1 marking convention for ACX114YUQ-13R?
Pin 1 is identified by a small dot or notch on the top surface near the left edge of the SOT363 package. When oriented with the marking side up and the notch/dot at the top-left corner, pins are numbered counter-clockwise: pin 1 (NPN emitter), pin 2 (NPN base), pin 3 (PNP emitter), pin 4 (PNP collector), pin 5 (PNP base), pin 6 (NPN collector).
Does ACX114YUQ-13R support 3.3 V logic-level drive?
Yes - the NPN section turns on fully at VIN ≥ 1.4 V (typ.), and the PNP section activates at VIN ≤ −1.4 V (typ.), making both sections compatible with standard 3.3 V CMOS/TTL logic outputs without level shifting. Input current remains ≤ 0.88 mA at 5 V drive, ensuring minimal loading.
How does the −13R suffix affect tape orientation?
The "−13R" suffix indicates the device is rotated 180° within the pocket tape compared to standard −13 packaging. This rotation aligns the marking code (1Y2) toward the sprocket holes, facilitating correct orientation during automated pick-and-place placement without requiring machine vision correction or custom feeder setup.
Can ACX114YUQ-13R be used in linear amplifier configurations?
No - this device is optimized for switching operation only. Its pre-biased resistor network fixes base current, preventing adjustable biasing required for linear amplification. The datasheet specifies all electrical characteristics under switching test conditions (e.g., pulsed IC, defined VO and IO thresholds), and no small-signal hfe or noise figure data is provided for analog gain applications.
