Product details
Overview
DCX114YUQ-7-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 capability (NPN), and AEC-Q101 qualification for automotive signal switching applications such as LED driver control and logic-level translation.
For engineers reviewing the DCX114YUQ-7-F datasheet, DCX114YUQ-7-F pinout, DCX114YUQ-7-F application, or DCX114YUQ-7-F equivalent, key selection criteria include input voltage thresholds (VI(on) = 1.4V / −1.4V), output saturation voltage (VCE(sat) ≤ 0.3V / −0.3V), DC current gain (GI = 68–80), and thermal resistance (RθJA = 625°C/W) under SOT363 mounting conditions.
Technical Context
This dual-transistor device integrates matched NPN and PNP silicon transistors with laser-trimmed on-chip bias resistors (R1 = 10kΩ, R2 = 47kΩ), enabling direct interface with 3.3V/5V logic without external base resistors. It supports bidirectional level shifting and push-pull output configurations.
The complementary structure allows simultaneous sourcing and sinking of up to ±70mA per channel at VO = ±50V, with guaranteed VI(off) ≤ ±0.3V and VI(on) ≥ ±1.4V across temperature, ensuring reliable turn-on/turn-off in automotive body control modules and sensor interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO | ±50V - Maximum supply voltage tolerance for both NPN and PNP sections, supporting 24V automotive rail operation with margin. |
| IO (NPN/PNP) | ±70mA - Continuous output current rating per transistor, sufficient for driving small relays or LEDs directly. |
| VI(on) | +1.4V / −1.4V - Minimum input voltage required to saturate respective transistor, compatible with standard CMOS/TTL logic levels. |
| VCE(sat) | ≤ +0.3V / −0.3V - Low saturation voltage ensures minimal power loss and heat generation during switching. |
| GI | 68–80 - DC current gain at VO = ±5V, IO = ±10mA, enabling predictable current amplification without external feedback. |
| R1/R2 | 10kΩ / 47kΩ - Precisely trimmed internal bias resistors eliminate need for external components in basic switch applications. |
| PD | 200mW - Total package power dissipation limit, derated linearly above +25°C ambient per 625°C/W thermal resistance. |
Pinout & Package
Package: SOT363 - 6-pin surface-mount plastic package (2.15mm × 2.10mm × 0.95mm), moisture sensitivity level 1, matte tin-plated leads, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NPN Emitter (EQ1) | Common emitter connection for NPN transistor; tied to ground or low-side return path in typical switch configuration. |
| 2 | NPN Base (BQ1) | Input node for NPN section; internally connected to R1 and R2 network, accepts logic-level drive signals. |
| 3 | NPN Collector (CQ1) | Output node for NPN section; sinks current when active, used for low-side switching or pull-down function. |
| 4 | PNP Collector (CQ2) | Output node for PNP section; sources current when active, used for high-side switching or pull-up function. |
| 5 | PNP Base (BQ2) | Input node for PNP section; internally connected to same R1/R2 network as Pin 2, enables complementary control. |
| 6 | PNP Emitter (EQ2) | Common emitter connection for PNP transistor; tied to VCC or high-side supply in typical switch configuration. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and body electronics under IATF 16949 manufacturing. |
| Integrated bias network | Matched 10kΩ/47kΩ resistor pair eliminates external base resistors, reducing BOM count and PCB area by ~2 components per channel. |
| Complementary NPN+PNP pair | Enables true push-pull output stages without cross-conduction risk, ideal for driving capacitive loads or bidirectional bus lines. |
| Low VCE(sat) | ≤ ±0.3V at ±70mA ensures <21mW conduction loss per transistor, minimizing thermal stress in compact layouts. |
| Green, RoHS-compliant | Fully lead-free, halogen- and antimony-free construction meets EU Directive 2015/863/EU and automotive environmental requirements. |

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 |
|---|---|---|---|
| DCX114YU-7-F | No Q suffix; identical electrical specs but not AEC-Q101 qualified or PPAP capable. | Suitable for commercial-grade designs where automotive qualification is not required. | Select when cost sensitivity outweighs automotive compliance needs and lifecycle support is less critical. |
| ACX114YUQ-7-F | Direct replacement per Diodes' NRND notice; same pinout, bias values, and AEC-Q101 qualification. | Identical functional behavior; intended for new designs replacing DCX114YUQ-7-F. | Preferred for new designs requiring long-term supply continuity and full automotive change control documentation. |
Compared with DCX114YUQ-7-F, DCX114YU-7-F offers identical performance at lower qualification cost but lacks automotive traceability, while ACX114YUQ-7-F provides identical functionality with assured long-term availability and updated manufacturing controls.

FAQ
Is DCX114YUQ-7-F pin-compatible with other DCX-series pre-biased transistors?
Yes, all DCX (XXXX) U and UQ variants share identical SOT363 pinout and internal topology. The only differences lie in bias resistor values (e.g., DCX114YUQ uses 10kΩ/47kΩ, while DCX144EUQ uses 47kΩ/47kΩ), so substitution requires verification of input/output voltage thresholds and gain requirements for the target circuit.
What does the "Q" suffix signify in DCX114YUQ-7-F?
The "Q" suffix denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities. It confirms compliance with automotive reliability testing standards including HTOL, TC, HAST, and ESD, distinguishing it from non-Q variants like DCX114YU-7-F intended for commercial use.
Can DCX114YUQ-7-F drive a 100mA load?
No-its absolute maximum rated output current is ±70mA per transistor. Exceeding this risks thermal runaway or permanent damage. For 100mA loads, consider DCX123JUQ-7-F (±100mA) or discrete solutions with external biasing and thermal management.
Why is DCX114YUQ-7-F marked NRND in Diodes' ordering table?
NRND ("Not Recommended for New Design") indicates Diodes has introduced ACX114YUQ-7-F as its designated replacement with identical specifications and enhanced long-term supply assurance. Existing DCX114YUQ-7-F inventory remains fully functional and supported, but new designs should adopt the ACX variant.
