Product details
Overview
DCX115EU-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, featuring 100kΩ/100kΩ integrated base resistors, 50V VO, ±20mA output current rating, and AEC-Q101 qualification for automotive signal switching applications such as LED driver bias control and logic-level translation in body electronics modules.
For engineers reviewing the DCX115EU-7-F datasheet, DCX115EU-7-F pinout, DCX115EU-7-F application, or DCX115EU-7-F equivalent, key selection criteria include verified input voltage thresholds (VI(on) = −3V / +3V), guaranteed DC current gain (GI = 82 at IO = ±5mA), thermal derating behavior (625°C/W RθJA), and SOT363 footprint compatibility with high-density PCB layouts.
Technical Context
This dual-transistor device integrates matched NPN and PNP silicon epitaxial planar transistors with precision laser-trimmed 100kΩ base resistors on each emitter leg, enabling direct TTL/CMOS-level drive without external biasing. It operates across −55°C to +150°C with symmetrical ±50V breakdown ratings and ±0.3V saturation voltages.
The complementary configuration supports push-pull output stages and level-shifting circuits where matched turn-on characteristics (VI(on) = ±3V at IO = ±1mA) and low leakage (<±0.5μA IO(off)) are required for reliable digital interface conditioning in automotive control units.
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 | ±20mA - Continuous output current per transistor, sufficient for driving small-signal loads like optocoupler LEDs or gate inputs. |
| VI(on) | +3V / −3V - Input voltage threshold at which output switches on, enabling direct interface with 3.3V/5V logic families. |
| GI | 82 - DC current gain at VO = ±5V and IO = ±5mA, ensuring stable switching with minimal base drive overhead. |
| R1/R2 | 100kΩ/100kΩ - Matched internal base resistors eliminate external component count and improve layout consistency. |
| PD | 200mW - Total package power dissipation limit, requiring thermal derating above +25°C ambient per 625°C/W RθJA. |
| TJ | −55°C to +150°C - Full operating junction temperature range validated for under-hood automotive environments. |

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 |
|---|---|---|---|
| DCX143ZU-7-F | Asymmetric R1/R2 (4.7kΩ/47kΩ); higher ±100mA IO; lower VI(on) (±1.3V) | Better suited for high-current logic buffering where faster switching and lower drive voltage are prioritized over resistor matching. | Select when needing higher output current and reduced input threshold, but accept mismatched bias networks. |
| DCX114YU-7-F | Asymmetric R1/R2 (10kΩ/47kΩ); ±70mA IO; VI(on) = ±1.4V | Optimized for medium-current digital isolation in industrial I/O modules with tighter input voltage margins. | Choose for cost-sensitive designs requiring moderate drive strength and asymmetric gain optimization. |
Compared with DCX115EU-7-F, DCX143ZU-7-F delivers higher current and lower input threshold at the expense of resistor matching, while DCX114YU-7-F offers balanced performance for general-purpose digital interfacing with asymmetric biasing-neither matches the precise 100kΩ/100kΩ symmetry critical for matched push-pull timing in automotive signal chains.

FAQ
What is the maximum continuous output current per transistor in DCX115EU-7-F?
The DCX115EU-7-F supports ±20mA continuous output current for both its NPN and PNP sections under standard conditions (TA = +25°C). This rating is confirmed in the Absolute Maximum Ratings table and applies to steady-state operation before thermal derating begins above ambient temperature.
Does DCX115EU-7-F require external base resistors for basic switching operation?
No. The device integrates matched 100kΩ base resistors (R1 and R2) for both transistors, enabling direct connection to 3.3V or 5V logic outputs without external bias components. This is explicitly stated in the Features section and verified in the Electrical Characteristics tables.
Is DCX115EU-7-F qualified for automotive applications?
Yes. DCX115EU-7-F is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. This qualification is documented in the Features section and supported by Diodes' product definitions page referenced in the datasheet.
What is the thermal resistance (RθJA) of DCX115EU-7-F in standard FR-4 mounting?
The junction-to-ambient thermal resistance is 625°C/W when mounted on an FR-4 PCB with minimum recommended pad layout, as specified in the Thermal Characteristics table. This value governs power derating above +25°C ambient and is validated per JESD51-2 standards.
