Product details
Overview
DCX115EK-7-F from Diodes Incorporated is a dual complementary pre-biased transistor in SOT26 package, integrating one NPN and one PNP transistor with built-in 100kΩ base bias resistors (R1 = R2 = 100kΩ) per channel. It supports ±50V VCEO, delivers ±20mA output current, operates from −55°C to +150°C, and is qualified for automotive-grade applications per AEC-Q101 requirements.
For engineers reviewing the DCX115EK-7-F datasheet, DCX115EK-7-F pinout, DCX115EK-7-F application, or DCX115EK-7-F equivalent, key selection criteria include input voltage thresholds (±0.5V VI(OFF), ±1.9V VI(ON)), output saturation voltage (±0.3V VCE(sat)), DC current gain (GL = 82), and thermal resistance (RθJA = 417°C/W).
Technical Context
This device implements a dual-channel, complementary pre-biased configuration where each transistor includes two integrated 100kΩ resistors forming a Thevenin-equivalent bias network. The NPN and PNP sections share identical absolute maximum ratings: ±50V VCEO, ±100mA IC(MAX), and 300mW total power dissipation on FR-4 PCB.
Electrical behavior is defined by discrete threshold voltages: VI(OFF) = ±0.5V and VI(ON) = ±1.9V at VO = ±0.3V, with matched input current (±0.15mA at VI = ±5V) and output current capability (±20mA at VO(on) = ±0.3V). Both sections exhibit hFE = 100–600 and fT = 250MHz.
Key Specifications

| VI(ON) | ±1.9V - Minimum input voltage required to achieve VO ≤ ±0.3V at IO = ±5mA |
| VCE(sat) | ±0.3V - Low-saturation voltage ensuring <100mW conduction loss at rated output current |
| GL | 82 - DC current gain ratio (IO/IIN) confirming stable digital switching performance |
| RθJA | 417°C/W - Thermal resistance defining junction-to-ambient temperature rise under standard SMT mounting |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DCX114EK-7 | R1 = R2 = 10kΩ - 10× lower bias resistance increases input current draw (±0.88mA at ±5V) | Better suited for higher-speed switching where faster turn-on is needed despite higher drive demand | Select when driving from low-impedance sources or needing reduced propagation delay |

FAQ
What is the maximum operating temperature for DCX115EK-7-F?
The DCX115EK-7-F is rated for operation from −55°C to +150°C, with thermal resistance RθJA = 417°C/W measured on FR-4 PCB using minimum recommended pad layout. This specification is validated per AEC-Q101 stress testing protocols and applies across its full voltage and current operating range.
Does DCX115EK-7-F require external base resistors?
No. DCX115EK-7-F integrates two 100kΩ bias resistors per channel (R1 = R2 = 100kΩ), forming a complete Thevenin-equivalent base drive network. This eliminates the need for external resistors in standard digital logic interfacing, reducing BOM count and PCB area.
How does the dual complementary structure improve circuit design?
The integrated NPN+PNP pair enables push-pull or H-bridge half-driver configurations within a single SOT26 footprint. This reduces interconnect inductance, improves timing matching between channels, and simplifies layout versus discrete transistor pairs-especially beneficial in motor control and relay driving applications.
Is DCX115EK-7-F compliant with automotive reliability standards?
Yes. DCX115EK-7-F is qualified to AEC-Q101, manufactured in IATF 16949-certified facilities, and supports PPAP documentation. Its construction meets halogen- and antimony-free "Green" requirements (<900ppm Br/Cl, <1000ppm Sb) and RoHS 3 (2015/863/EU) compliance.
