Product details
Overview
DCX114EH-7 from Diodes Incorporated is a complementary NPN/PNP pre-biased small-signal transistor pair in SOT563 package, featuring integrated 10kΩ input resistors (R1) and 10kΩ emitter resistors (R2) for both transistors. It supports ±50V VCEO, ±100mA output current, 150mW total power dissipation, and operates from −55°C to +150°C - used in level-shifting, logic interface, and dual-channel switching circuits.
For engineers reviewing the DCX114EH-7 datasheet, DCX114EH-7 pinout, DCX114EH-7 application, or DCX114EH-7 equivalent, key selection criteria include verified R1/R2 resistor values (10kΩ/10kΩ), confirmed NPN/PNP complementarity, guaranteed SOT563 mechanical compatibility, and validated input/output voltage thresholds (VIN(ON) = ±3.0V, VO(ON) = ±0.1V at IO/IIN = 10mA/0.5mA).
Technical Context
This device integrates matched NPN and PNP transistors with monolithic biasing resistors on a single die, enabling compact dual-polarity switching without external base resistors. Its symmetrical ±50V breakdown ratings, ±100mA output capability, and identical R1/R2 values (10kΩ each) support balanced push-pull operation in digital interface stages.
The SOT563 six-terminal package assigns dedicated emitter, base, and collector terminals for each transistor, with internal resistor connections fixed per schematic - eliminating layout ambiguity. Thermal resistance of 833°C/W (on FR-4) and −55°C to +150°C operating range support industrial-grade reliability in space-constrained PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO (NPN/PNP) | ±50 V - supports rail-to-rail switching across 5V–40V logic domains |
| IO (Max) | ±100 mA - drives moderate-load LEDs, relays, or gate inputs without external buffering |
| R1 / R2 | 10 kΩ / 10 kΩ - enables direct microcontroller GPIO drive with no external bias components |
| PD (Total) | 150 mW - limits continuous dissipation to ~100mA @ 1.5V VCE(SAT) in ambient conditions |
| VIN(ON) | ±3.0 V @ IO = 10 mA - ensures reliable turn-on with standard 3.3V/5V logic outputs |
| VO(ON) | ±0.1 V @ IO/IIN = 10 mA/0.5 mA - minimizes voltage drop in low-side/high-side switch paths |
| TJ Range | −55°C to +150°C - qualified for under-hood automotive, industrial control, and power supply monitoring |
Pinout & Package
SOT563 is a 6-pin, surface-mount plastic package with 0.6mm pitch, 1.6mm × 1.2mm footprint, and 0.5mm nominal height. Terminals are matte tin annealed over copper leadframe, rated for J-STD-020 Level 1 moisture sensitivity and UL 94V-0 flammability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3 (NPN Collector) | NPN collector connection | Output node for NPN channel; sinks current when active |
| 4 (PNP Collector) | PNP collector connection | Output node for PNP channel; sources current when active |
| 5 (PNP Base) | PNP base connection | Connected to R1 (10kΩ) input node; driven by inverted logic or complementary signal |
| 6 (PNP Emitter) | PNP emitter connection | Internally tied to R2 (10kΩ); referenced to VCC in high-side switch configuration |
Key Features
| Feature | Design Value |
|---|---|
| Complementary NPN/PNP pair | Monolithic integration eliminates matching drift and reduces board area vs. discrete pairs |
| Built-in bias resistors (R1 = R2 = 10kΩ) | Removes need for four external resistors in push-pull or inverter designs |
| Green, halogen-free, RoHS-compliant construction | Meets EU Directive 2015/863/EU with <900ppm Br, <900ppm Cl, <1000ppm Sb |
| 833°C/W thermal resistance (RθJA) | Enables 100mA operation on standard FR-4 without heatsinking at ≤50°C ambient |
| −55°C to +150°C operating range | Validated for extended-temperature applications including motor control feedback and power supply sequencing |
Applications
| Logic-Level Translation | Dual-Channel Load Switching |
|---|---|
Use Scenario: Interfacing 3.3V microcontroller GPIOs to 5V/12V peripheral logic inputs. IC Role / Device Role / Timing Role: NPN section acts as low-side level shifter; PNP section provides inverted high-side translation. Use Value: Eliminates discrete resistor networks while maintaining <100ns propagation delay and ±3.0V input threshold compatibility. |
Use Scenario: Independently enabling/disabling two loads (e.g., LED strings or sensor modules) from one controller. IC Role / Device Role / Timing Role: NPN handles sink-switching (ground return); PNP handles source-switching (VCC feed). Use Value: Achieves matched turn-on characteristics (VO(ON) ≤ ±0.1V) and simultaneous control via shared input node. |
| Push-Pull Output Stage | Power Supply Sequencing Monitor |
Use Scenario: Driving capacitive bus lines (e.g., I²C pull-up nodes) with active pull-down and pull-up capability. IC Role / Device Role / Timing Role: Complementary pair forms Class-B output buffer with zero static current between transitions. Use Value: Reduces bus rise/fall time asymmetry and prevents shoot-through due to matched hFE (100–600) and saturation voltages. |
Use Scenario: Monitoring undervoltage lockout (UVLO) status across multiple rails (e.g., 3.3V and 5V) in FPGA power systems. IC Role / Device Role / Timing Role: Each transistor independently compares rail voltage against reference using resistor-divider input. Use Value: Enables dual-rail fault indication with single-input logic compatibility and guaranteed ±0.5µA leakage at off-state. |
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 |
|---|---|---|---|
| DCX143EH-7 | R1 = 4.7kΩ, R2 = 4.7kΩ - lower input impedance, higher drive current (±100mA @ VIN = ±1.9V) | Better suited for 1.8V–3.3V logic drive; less margin for 5V-tolerant inputs | Select when driving heavier loads from low-voltage MCUs and tighter VIN(OFF) (<±0.5V) is required. |
| DCX123JH-7 | R1 = 2.2kΩ, R2 = 47kΩ - asymmetric biasing optimized for digital inverter function (hFE = 80) | Designed specifically for Schmitt-trigger-like switching with hysteresis; not interchangeable in linear gain roles | Choose only for dedicated inverter applications where input threshold symmetry is not required. |
Compared with DCX143EH-7 and DCX123JH-7, DCX114EH-7 offers symmetric 10kΩ/10kΩ biasing ideal for bidirectional level translation, whereas DCX143EH-7 favors low-voltage drive and DCX123JH-7 targets inverting logic functions - making DCX114EH-7 the optimal choice for matched push-pull or dual-rail interface tasks.

FAQ
What is the exact resistor configuration inside DCX114EH-7?
DCX114EH-7 contains two independent pre-biased transistors: an NPN with 10kΩ base resistor (R1) and 10kΩ emitter resistor (R2), and a PNP with identical 10kΩ R1 and 10kΩ R2 values. These are monolithically integrated and electrically isolated - confirmed in DS30422 Rev. 5-2, page 1 (Features table) and page 3 (Electrical Characteristics).
Can DCX114EH-7 replace discrete BC846/BC856 pairs in existing designs?
Yes, but only if the original design uses external 10kΩ base/emitter resistors per transistor. DCX114EH-7 replicates that bias network internally, reducing component count by four passives. However, its SOT563 pinout differs from SC-70 or SOT-363 packages - PCB layout revision is required for mechanical compatibility.
Is DCX114EH-7 suitable for analog amplification?
No. DCX114EH-7 is optimized for switching applications: its hFE is specified only at IC = ±1mA, VCE = ±5V, and it lacks linearity characterization (e.g., distortion, fT stability over bias). The integrated resistors also prevent external bias tuning required for stable small-signal amplification.
Does DCX114EH-7 meet automotive AEC-Q101 requirements?
No. While DCX114EH-7 operates from −55°C to +150°C and is RoHS/halogen-free, Diodes Incorporated does not list it in their AEC-Q101-qualified portfolio. For automotive applications, consider the AEC-Q101-certified DDC114EUA-7 (same functionality, same package, qualified per stress test standard).
