Product details
Overview
DCX114TU-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, designed for compact logic-level switching with integrated 10kΩ R1 bias resistors on both transistors. It supports ±50V VCEO, delivers ±100mA continuous output current per channel, and achieves hFE of 100–600 at IC = ±1mA, VCE = ±5V - enabling direct interface with 3.3V/5V microcontrollers in level-shifting and load-driving applications.
For engineers reviewing the DCX114TU-7-F datasheet, DCX114TU-7-F pinout, DCX114TU-7-F application, or DCX114TU-7-F equivalent, key selection criteria include verified dual-channel complementary operation, matched input resistor tolerance (±30%), guaranteed VCE(sat) ≤ ±0.3V at IC/IB = ±1mA/±0.1mA, and AEC-Q101 qualification readiness for automotive signal conditioning.
Technical Context
This device integrates two monolithic silicon transistors - one NPN and one PNP - with identical 10kΩ input bias resistors (R1) on each base, eliminating external bias components. The complementary topology enables push-pull output stages without cross-conduction risk when driven by single-ended logic signals.
Each transistor exhibits symmetrical absolute maximum ratings: ±50V VCEO, ±100mA IO, ±100mA ICM, and shares thermal characteristics including 200mW total power dissipation and 625°C/W junction-to-ambient thermal resistance on FR-4 PCBs with minimum pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | ±50V - Enables safe operation in 24V industrial bus and 36V automotive subsystems with margin. |
| IO (continuous) | ±100mA per channel - Sufficient to drive LEDs, small relays, or logic inputs without external amplification. |
| VCE(sat) | ≤ ±0.3V at IC/IB = ±1mA/±0.1mA - Minimizes conduction loss and self-heating in high-duty-cycle switching. |
| hFE | 100–600 at IC = ±1mA, VCE = ±5V - Ensures reliable turn-on across process and temperature variation with low base drive. |
| R1 | 10kΩ ±30% - Provides consistent, predictable base current limiting for logic-compatible input thresholds. |
| PD | 200mW total - Supports dual-channel operation within thermal limits on standard SMT layouts. |
| TJ range | −55°C to +150°C - Validated for under-hood automotive and industrial ambient environments. |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount plastic package with 0.65mm lead pitch, UL 94V-0 rated molding compound, matte tin-plated leads, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NPN Emitter (EQ1) | Common emitter node for NPN transistor; connects to ground or low-side return path. |
| 2 | NPN Base (BQ1) via R1 | Input terminal with integrated 10kΩ resistor to NPN base; accepts logic-high signal to enable NPN. |
| 3 | NPN Collector (CQ1) | Output collector for NPN; sinks current when active, used for low-side switching. |
| 4 | PNP Collector (CQ2) | Output collector for PNP; sources current when active, used for high-side switching. |
| 5 | PNP Base (BQ2) via R1 | Input terminal with integrated 10kΩ resistor to PNP base; accepts logic-low signal to enable PNP. |
| 6 | PNP Emitter (EQ2) | Common emitter node for PNP transistor; connects to supply rail or high-side source. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary NPN+PNP pair | Single-package solution eliminates timing skew and layout mismatch between discrete switches. |
| Integrated 10kΩ bias resistors (R1 only) | Removes need for four external resistors in push-pull drivers, reducing BOM count and board area. |
| ±50V breakdown rating | Supports robust operation in 24V/36V systems with transient margin against load dump or inductive kickback. |
| AEC-Q101 qualification support | Manufactured in IATF 16949-certified facilities with PPAP capability - suitable for automotive signal interface modules. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) meets global environmental compliance 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 |
|---|---|---|---|
| DCX143TU-7-F | Same SOT363 package and R1 = 4.7kΩ, but lower hFE min (100) and higher input current (±0.88mA at VI = ±5V). | Better suited for faster switching where lower base resistance reduces propagation delay. | Select when drive strength >100mA is not required and lower input threshold voltage is needed. |
| DCX114EU-7-F | Includes both R1 and R2 (10kΩ/10kΩ), enabling active pull-down on base nodes - unlike R1-only DCX114TU. | Provides improved noise immunity and faster turn-off in noisy industrial environments. | Choose when bidirectional base control or guaranteed fast turn-off is critical, accepting +1 pin function complexity. |
Compared with DCX143TU-7-F, DCX114TU-7-F offers higher input impedance and lower base current demand; compared with DCX114EU-7-F, it trades off active pull-down capability for simpler bias architecture and reduced internal component count.

FAQ
What is the maximum operating temperature for DCX114TU-7-F?
The device is rated for junction and storage temperatures from −55°C to +150°C. Its 625°C/W thermal resistance requires adherence to the recommended SOT363 pad layout on FR-4 PCBs to maintain safe operation at full 200mW dissipation across this range.
Does DCX114TU-7-F include base-emitter resistors (R2)?
No - DCX114TU-7-F is an R1-only configuration, meaning it integrates only the 10kΩ base-input resistors (R1) on both NPN and PNP transistors. It does not include R2 pull-down resistors, distinguishing it from R1/R2 variants like DCX114EU-7-F.
Can DCX114TU-7-F replace discrete transistors in existing designs?
Yes - its pinout matches standard SOT363 complementary transistor layouts, and its 10kΩ R1 values provide predictable base current for 3.3V/5V logic drive. Layout adaptation is minimal, though saturation voltage and gain must be verified against original discrete BJT performance.
Is DCX114TU-7-F qualified for automotive use?
While DCX114TU-7-F itself is not explicitly marked AEC-Q101 qualified in the datasheet, it belongs to the DCX U-series manufactured in IATF 16949-certified facilities and shares process, testing, and packaging with AEC-Q101-qualified variants (e.g., DCX114YUQ). Customers requiring formal qualification should consult Diodes' PPAP documentation.
