Product details
Overview
DCX114EU-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, integrating 10kΩ base resistors on both transistors for direct logic-level switching. It supports ±50V supply voltage, delivers ±50mA continuous output current per channel, and achieves VCE(sat) ≤ ±0.3V at IC/IB = 10mA/0.5mA - enabling compact load switching in automotive body control modules.
For engineers reviewing the DCX114EU-7-F datasheet, DCX114EU-7-F pinout, DCX114EU-7-F application, or DCX114EU-7-F equivalent, this device is selected for space-constrained dual-polarity interface circuits requiring AEC-Q101 qualification, low-input-current activation (±0.88mA at ±5V), and guaranteed R1/R2 matching within ±20% tolerance.
Technical Context
This dual-transistor array integrates matched NPN and PNP silicon epitaxial planar devices with monolithically embedded 10kΩ base bias resistors on each transistor - eliminating external resistor placement while maintaining independent control of emitter-follower or common-emitter configurations. The complementary topology enables push-pull output stages without cross-conduction risk when driven by single-rail logic.
Each transistor exhibits identical absolute maximum ratings: ±50V VCEO, ±100mA ICM, and 200mW total package power dissipation. Thermal resistance is fixed at 625°C/W (Junction-to-Ambient) on FR-4 PCBs using minimum recommended pad layout - confirming suitability for thermally constrained automotive cabin modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±50V - supports wide-range automotive battery-supplied systems including cold-crank and load-dump conditions. |
| Output Current | ±50mA continuous - sufficient to drive small relays, LEDs, or gate inputs of downstream MOSFETs without external amplification. |
| VCE(sat) | ≤ ±0.3V at IC/IB = 10mA/0.5mA - minimizes conduction loss and self-heating in always-on control paths. |
| Input Resistor (R1/R2) | 10kΩ ±30% - provides predictable base current limiting for TTL/CMOS-compatible input drive with no external components. |
| DC Current Gain (hFE) | 100–600 at IC = ±1mA - ensures reliable saturation across process and temperature variation in industrial sensor interfaces. |
| Power Dissipation | 200mW total - limits thermal rise to <125°C junction temperature under worst-case ambient (85°C) with standard PCB layout. |
| AEC-Q101 Qualified | Yes - validated for automotive applications including interior lighting, door lock actuators, and HVAC fan control. |

| AEC-Q101 Qualification | Validated for automotive use with PPAP capability and IATF 16949 manufacturing - meets requirements for ASIL-B supporting functions. |
| Low Input Current Requirement | ±0.88mA max at ±5V input - compatible with microcontroller GPIOs without buffer stages, preserving drive strength for other peripherals. |
| Matched R2/R1 Tolerance | ±20% ratio tolerance ensures symmetrical turn-on thresholds between NPN and PNP channels - critical for balanced timing in motor direction control. |
Applications
| Automotive Door Lock Actuator | Industrial PLC Output Module |
|---|---|
|
Use Scenario: Driving solenoid-based door latch mechanisms in 12V vehicle architectures with reverse-battery protection. IC Role / Device Role / Timing Role: Dual-channel level translator and current amplifier - NPN switches ground path, PNP supplies VBAT to solenoid coil during unlock sequence. Use Value: Eliminates need for separate high-side and low-side drivers; ±50V rating withstands load-dump transients up to 40V. |
Use Scenario: Providing isolated 24V DC output switching for field devices in factory automation cabinets. IC Role / Device Role / Timing Role: Logic-compatible output stage - converts 3.3V/5V controller signals into robust ±24V sourcing/sinking capability. Use Value: 200mW package power budget allows sustained 50mA operation without heatsinking in confined DIN-rail enclosures. |
| LED Tail Light Driver | USB-C Port Power Switching |
|
Use Scenario: Controlling red/amber LED arrays in rear lighting clusters where thermal management is limited by polycarbonate housing. IC Role / Device Role / Timing Role: Constant-current switch - NPN handles brake-light intensity modulation, PNP manages turn-signal flashing via PWM input. Use Value: VCE(sat) ≤ ±0.3V reduces power loss to <15mW per channel, limiting junction temperature rise to <15°C above ambient. |
Use Scenario: Enabling/disabling VBUS and CC line termination in USB-C receptacles compliant with USB PD 3.0 specifications. IC Role / Device Role / Timing Role: Dual-polarity enable switch - NPN grounds CC pull-down, PNP connects VCONN to auxiliary power rail during cable detection. Use Value: Matched R1/R2 ensures simultaneous activation timing within 10ns skew - preventing USB-C enumeration failures during hot-plug events. |
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-7-F | 47kΩ base resistors instead of 10kΩ - higher input impedance, lower input current (±0.18mA at ±5V). | Better suited for high-impedance MCU outputs but slower switching due to reduced base drive. | Select when driving from weak GPIOs or when lower standby current is prioritized over speed. |
| DCX114YU-7-F | Asymmetric bias: 10kΩ on NPN, 47kΩ on PNP - enables independent optimization of turn-on thresholds. | Used where NPN and PNP require different drive strengths, e.g., asymmetric motor H-bridge control. | Choose when precise independent control of NPN/PNP activation voltages is required. |
Compared with DCX144EU-7-F and DCX114YU-7-F, DCX114EU-7-F offers balanced 10kΩ biasing for symmetric logic-level drive, making it optimal for push-pull signaling where equal rise/fall time and threshold matching are essential - such as in LIN bus transceiver enable circuits or dual-directional I²C level shifters.

FAQ
What is the maximum operating temperature for DCX114EU-7-F?
The device operates from −55°C to +150°C junction temperature. At 85°C ambient with standard FR-4 PCB layout, its 625°C/W thermal resistance limits power dissipation to 104mW before reaching 150°C - well within the 200mW absolute maximum rating when derated per Figure 1.
Does DCX114EU-7-F support reverse-battery protection?
Yes - its ±50V VCEO rating and complementary structure allow safe operation during reverse-polarity events up to −14V, provided external clamping diodes limit reverse voltage across the package. This makes it suitable for 12V automotive systems with ISO 16750-2 compliance requirements.
Can DCX114EU-7-F be used in linear amplifier mode?
No - it is optimized for switching operation only. The integrated 10kΩ base resistors fix biasing for saturation, and the hFE specification (100–600) applies only at IC = ±1mA, VCE = ±5V. Linear gain stability and frequency response are not characterized or guaranteed.
Is the SOT363 package RoHS and REACH compliant?
Yes - DCX114EU-7-F is fully RoHS 3 (2015/863/EU) compliant with no intentionally added lead, and halogen-free (<900ppm Br, <900ppm Cl, <1000ppm Sb). It meets REACH SVHC thresholds and carries Diodes' "Green" product designation per Note 3 in DS30347 Rev. 24-2.
