Product details
Overview
DCX143ZU-13R-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, featuring integrated 4.7kΩ and 47kΩ bias resistors, 50V VO, ±100mA peak output current, and AEC-Q101 qualification for automotive signal switching applications.
For engineers reviewing the DCX143ZU-13R-F datasheet, DCX143ZU-13R-F pinout, DCX143ZU-13R-F application, or DCX143ZU-13R-F equivalent, key selection criteria include input voltage thresholds (VI(on) = −1.3V / +1.3V), output saturation voltage (VCE(sat) ≤ ±0.3V), DC current gain (hFE = 80), and thermal resistance (RθJA = 625°C/W).
Technical Context
This dual-transistor device integrates matched NPN and PNP silicon epitaxial planar transistors with on-chip base-emitter resistors (R1 = 4.7kΩ, R2 = 47kΩ) to enable direct logic-level drive without external biasing. It supports bidirectional switching in low-power digital interface circuits.
The complementary configuration allows simultaneous high-side (PNP) and low-side (NPN) control in push-pull outputs, level shifters, and LED drivers, with symmetrical absolute maximum ratings (±50V VO, ±100mA ICM) and matched hFE (80 typ. for both sections at VCE = −5V/+5V, IO = −10mA/+10mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO | ±50V - Maximum supply voltage tolerance for rail-to-rail operation in 24V/48V automotive and industrial systems. |
| IO (NPN/PNP) | +100mA / −100mA - Continuous output current capability per section, enabling direct drive of small solenoids or logic buffers. |
| VI(on) | +1.3V / −1.3V - Input turn-on voltage threshold at IO = ±5mA, compatible with 1.8V–5V CMOS/TTL logic families. |
| VCE(sat) | +0.3V / −0.3V - Low saturation voltage ensures <3% power loss at full load, critical for thermally constrained PCB layouts. |
| hFE | 80 (typ.) - DC current gain at IO = ±10mA, providing stable switching margin across temperature (−55°C to +150°C). |
| RθJA | 625°C/W - Junction-to-ambient thermal resistance on FR-4 board, defining derating curve for sustained 200mW total dissipation. |
| AEC-Q101 | Qualified - Validated for automotive use with PPAP support and IATF 16949 manufacturing, enabling deployment in body control modules. |

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 |
|---|---|---|---|
| DCX143EU-13R-F | R1 = R2 = 4.7kΩ (symmetric bias), lower VI(on) (+1.99V/−2.5V), higher IO (+20mA/−20mA max continuous) | Better suited for high-speed logic interfacing where matched input thresholds reduce skew; less ideal for asymmetric load driving. | Select when symmetric bias and faster switching (tr/tf < 35ns) are prioritized over wide input voltage range. |
| DCX123JU-13R-F | R1 = 2.2kΩ, R2 = 47kΩ; higher input current (IL = +3.6mA/−3.6mA at VI = ±5V); lower hFE (80 typ. but wider spread) | Optimized for high-gain, low-threshold switching in battery-powered IoT nodes with weak drive sources. | Choose when driving from low-current GPIOs (e.g., ARM Cortex-M0+) and needing guaranteed turn-on at <1.1V input. |
Compared with DCX143EU-13R-F and DCX123JU-13R-F, DCX143ZU-13R-F provides the widest usable input voltage window (±1.3V threshold) and best thermal stability for automotive-grade designs requiring consistent performance across extreme temperature cycles.

FAQ
What is the maximum continuous output current per transistor section?
The DCX143ZU-13R-F supports ±100mA continuous output current for both NPN and PNP sections under TA = +25°C with proper PCB thermal relief. Derating applies above 25°C per the 625°C/W RθJA curve; at 85°C ambient, maximum continuous current drops to ±60mA to maintain junction temperature below 150°C.
Can this device be used in a single-supply 5V system?
Yes-its ±50V VO rating and symmetric ±1.3V VI(on) thresholds allow robust operation in 5V systems. The NPN section switches on with VI ≥ +1.3V (relative to EQ1), while the PNP section activates with VI ≤ −1.3V (relative to EQ2), enabling true rail-to-rail input compatibility when referenced to local grounds.
Is the SOT363 package lead-free and RoHS compliant?
Yes-the DCX143ZU-13R-F uses matte tin-plated leads and a halogen-free, antimony-free green molding compound. It fully complies with EU RoHS Directive 2015/863/EU (RoHS 3), with lead content <100ppm and bromine/chlorine totals <1500ppm, verified per Diodes Incorporated's quality documentation.
How does the integrated resistor network affect switching speed?
The 4.7kΩ/47kΩ resistor network limits base drive current, resulting in typical turn-on/turn-off times of 85ns/70ns (NPN) and 95ns/75ns (PNP) at IO = ±50mA. This balances speed and power efficiency-faster than discrete 10kΩ biasing but slower than direct-drive configurations, making it optimal for <1MHz digital switching.
