Product details
Overview
DCX114YU-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, integrating 10kΩ and 47kΩ bias resistors for direct logic-level switching. It supports ±50V supply voltage, delivers ±70mA output current (NPN), ±70mA (PNP), and features VCE(sat) ≤ ±0.3V at IC/IB = 5mA/0.25mA - used in compact DC-DC converter enable control and dual-rail level-shifting interfaces.
For engineers reviewing the DCX114YU-7-F datasheet, DCX114YU-7-F pinout, DCX114YU-7-F application, or DCX114YU-7-F equivalent, key selection criteria include verified R1/R2 resistor values (10kΩ/47kΩ), guaranteed ±70mA output capability per channel, thermal derating compliance to 625°C/W, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device integrates two monolithic silicon transistors - one NPN and one PNP - with laser-trimmed on-chip base bias resistors (R1 = 10kΩ, R2 = 47kΩ) enabling single-pin digital input drive without external biasing. Each transistor operates independently with separate collector, emitter, and base connections routed through six terminals.
It supports bidirectional signal conditioning: NPN section switches positive loads up to +50V with VI(on) = +1.4V (IO = 1mA), while PNP section handles negative rail control with VI(on) = −1.4V (IO = −1mA); both exhibit matched hFE = 68–80 at ±5V and ±10mA load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±50V - enables use in 24V industrial bus and 48V telecom power rails without level translation. |
| Output Current (NPN/PNP) | ±70mA - sufficient to directly drive small relays, LED strings, or gate inputs of power MOSFETs. |
| VCE(sat) | ≤ ±0.3V at IC/IB = 5mA/0.25mA - minimizes conduction loss in high-duty-cycle switching applications. |
| Input Resistors | R1 = 10kΩ, R2 = 47kΩ - provides precise current-limited base drive for predictable turn-on behavior across temperature. |
| Power Dissipation | 200mW total (150mW per element max) - requires FR-4 PCB layout with minimum pad area per Diodes' recommended footprint. |
| Operating Temperature | −55°C to +150°C - validated for under-hood automotive modules and industrial motor control enclosures. |

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 |
|---|---|---|---|
| DCX124EU-7-F | R1 = R2 = 22kΩ; lower input current (0.36mA @ 5V) but reduced output current (±30mA). | Suitable for low-power logic buffering where drive strength is secondary to input sensitivity. | Select when interfacing with weak-drive MCUs (e.g., ultra-low-power ARM Cortex-M0+) and load currents stay below 25mA. |
| DCX123JU-7-F | R1 = 2.2kΩ, R2 = 47kΩ; higher input current (3.6mA @ 5V), higher output current (±100mA), but tighter thermal constraints. | Preferred for driving higher-current loads like small solenoids or optocoupler LEDs requiring >70mA. | Choose when system-level thermal management allows 150mW per element and faster switching (<50ns tf) is required. |
Compared with DCX114YU-7-F, DCX124EU-7-F offers lower power consumption but less drive strength, while DCX123JU-7-F delivers higher current at the cost of increased input loading - making DCX114YU-7-F the optimal balance for mid-range 12–24V control interfaces requiring AEC-Q101 compliance.

FAQ
What is the maximum allowable continuous current per transistor in DCX114YU-7-F?
The absolute maximum continuous output current is ±70mA for both NPN and PNP sections at TA = +25°C, with derating required above 25°C per the 625°C/W thermal resistance curve. Peak pulsed current is ±100mA, limited to 1% duty cycle with 10ms pulse width to avoid junction overheating.
Can DCX114YU-7-F be used in AC-coupled signal paths?
No - it is a DC-coupled, current-amplifying switch only. The internal resistors and bipolar junction structure require defined DC bias conditions; AC coupling would disrupt base-emitter forward bias and prevent proper saturation or cutoff operation.
Is the SOT363 package compatible with standard reflow profiles for lead-free soldering?
Yes - the device is fully RoHS 3 compliant and qualified for JEDEC J-STD-020 Level 1 moisture sensitivity. It supports standard lead-free reflow profiles with peak temperatures up to 260°C and ramp rates within IPC/JEDEC J-STD-020 limits.
Does DCX114YU-7-F support bidirectional current flow between its collectors?
No - each transistor operates unidirectionally: NPN conducts current from collector to emitter when base is forward-biased; PNP conducts from emitter to collector. There is no internal connection between CQ1 and CQ2, and they must be used in separate circuit branches.
