Product details
Overview
DCX123JUQ-7-F from Diodes Incorporated is a complementary pre-biased NPN+PNP transistor pair in SOT363, designed for level-shifting and signal switching in automotive and industrial control logic. It features 50V VO, R1 = 2.2kΩ / R2 = 47kΩ bias network, ±100mA peak output current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the DCX123JUQ-7-F datasheet, DCX123JUQ-7-F pinout, DCX123JUQ-7-F application, or DCX123JUQ-7-F equivalent, key selection criteria include input threshold voltage (VI(on) = 1.1V), on-state output voltage (VO(on) ≤ 0.3V), DC current gain (GI = 80), and thermal resistance (RθJA = 625°C/W) in compact SOT363 packaging.
Technical Context
This dual-transistor device integrates matched NPN and PNP silicon transistors with integrated base resistors-R1 = 2.2kΩ and R2 = 47kΩ-enabling direct TTL/CMOS interface without external biasing. The complementary topology supports push-pull output stages and bidirectional signal conditioning.
It operates across –55°C to +150°C, delivers ±100mA peak output current per channel, and maintains VCE(sat) ≤ ±0.3V at IC/IB = 5mA/0.25mA, ensuring low-loss switching in 5V and 12V logic domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VO Rating | 50V supply voltage - supports operation in 24V automotive systems with margin. |
| R1/R2 | 2.2kΩ / 47kΩ - sets precise input threshold (VI(on) = 1.1V) and ensures stable turn-on at 5mA load. |
| IO (NPN/PNP) | +100mA / –100mA - enables direct drive of small relays, LEDs, or gate inputs without buffer stages. |
| VO(on) | ≤ 0.3V - minimizes power loss and heat generation in high-duty-cycle switching. |
| GI (DC Gain) | 80 @ VO = 5V, IO = 10mA - provides sufficient current amplification for logic-level interfacing. |
| PD | 200mW - limits thermal rise to safe levels on standard FR-4 PCBs with minimum pad layout. |
| RθJA | 625°C/W - defines derating slope (200mW → 0mW at 150°C ambient) for thermal design validation. |
Pinout & Package
Package: SOT363 - ultra-compact 6-pin surface-mount package (2.15 × 2.10 × 0.95 mm), lead-free, halogen-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (BQ1) | NPN Base Input | Connected internally to R1–R2 node; accepts TTL/CMOS logic input for NPN switch. |
| 2 (EQ1) | NPN Emitter | Common emitter reference; tied to ground or low-side return path in typical configurations. |
| 3 (CQ1) | NPN Collector Output | Active-low open-collector output; sinks up to +100mA when driven. |
| 4 (CQ2) | PNP Collector | Active-high source output; supplies up to –100mA when base (Pin 5) is pulled low. |
| 5 (BQ2) | PNP Base Input | Internally biased via same R1/R2 network; complements Pin 1 for push-pull operation. |
| 6 (EQ2) | PNP Emitter | Connected to positive rail (e.g., 5V/12V); forms high-side switch with controlled turn-on threshold. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics. |
| Integrated bias network | Eliminates need for two external resistors per transistor, reducing BOM count and layout area by 4×. |
| Matched complementary pair | NPN and PNP share identical R1/R2 values and thermal coupling, enabling symmetrical switching behavior. |
| Low VCE(sat) | ≤ ±0.3V ensures <15mW conduction loss at 50mA, critical for thermally constrained PCBs. |
| SOT363 footprint | Compatible with high-speed pick-and-place and reflow processes; supports >20,000 units/hour assembly throughput. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased transistor pair applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DCX123JU-7-F | No Q-suffix; identical electrical specs but not AEC-Q101 qualified or PPAP-capable. | Limited to commercial-grade industrial use; unsuitable for automotive production programs. | Select only if AEC-Q101 certification and IATF 16949 traceability are not required. |
| DCX143ZU-7-F | R1/R2 = 4.7kΩ/47kΩ; higher VI(on) (1.3V) and lower IO (±100mA same, but GI = 80 at 5mA vs. 10mA). | Better noise immunity in noisy 12V environments; slightly slower turn-on in low-voltage logic interfaces. | Prefer when interfacing with 3.3V GPIO with marginal noise margin or where higher input threshold improves robustness. |
Compared with DCX123JU-7-F, the Q-suffix variant adds automotive qualification and full change control, while DCX143ZU-7-F trades lower input threshold for improved noise rejection-making DCX123JUQ-7-F optimal for cost-sensitive AEC-Q101 designs requiring precise 1.1V activation.

FAQ
What is the maximum operating temperature for DCX123JUQ-7-F?
The device is rated for junction and storage temperatures from –55°C to +150°C. Its thermal resistance RθJA is 625°C/W on FR-4 PCB with minimum pad layout, meaning power dissipation must be derated linearly above +25°C ambient-e.g., max 100mW at +125°C ambient-to stay within absolute maximum ratings.
Can DCX123JUQ-7-F replace discrete transistor + resistor combinations?
Yes-it integrates two matched transistors with precision 2.2kΩ/47kΩ bias resistors, eliminating four external components per channel. Verified layout compatibility with SOT363 footprint allows drop-in replacement in existing designs, provided pin mapping (BQ1/EQ1/CQ1/CQ2/BQ2/EQ2) matches the schematic symbol.
Is DCX123JUQ-7-F compliant with automotive quality standards?
Yes-it is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Full traceability, change control documentation, and green (halogen/antimony-free) compliance are supported per Diodes' product definitions and RoHS 3 (2015/863/EU) requirements.
What is the input voltage range for reliable switching?
The NPN section turns on at VI(on) ≈ 1.1V (typical) with VO = 0.3V and IO = 5mA; it remains off below VI(off) ≈ 0.5V. For PNP operation, corresponding thresholds are –1.1V and –0.5V. This 0.6V hysteresis ensures noise immunity in 5V logic systems with ±100mV ripple.
