Product details
Overview
ADC144EUQ-13 from Diodes Incorporated is an AEC-Q101 qualified NPN pre-biased dual transistor in SOT363 package, featuring integrated 47kΩ base resistors (R1/R2), 100mA maximum collector current per element, and −55°C to +150°C operating temperature range. It serves as a compact, automotive-grade digital switching solution for level translation and signal conditioning in body control modules.
For engineers reviewing the ADC144EUQ-13 datasheet, ADC144EUQ-13 pinout, ADC144EUQ-13 application, or ADC144EUQ-13 equivalent, key selection criteria include guaranteed ON/OFF thresholds (VI(ON) ≤ 3.0V, VI(OFF) ≥ 0.5V), low saturation voltage (VO(ON) ≤ 0.3V at 10mA), and ±30% R1 tolerance - critical for predictable logic-level interfacing in IATF 16949 production environments.
Technical Context
The ADC144EUQ-13 integrates two identical NPN transistors with monolithically embedded biasing networks (R1 = R2 = 47kΩ), eliminating external base resistors and reducing PCB footprint. Its design supports direct TTL/CMOS-compatible input drive with defined switching thresholds and stable DC current gain (GI ≥ 68) under 5V–50V supply conditions.
Thermal performance is specified for FR4 mounting: 270mW total power dissipation (150mW per element max), with RθJA = 450°C/W enabling operation up to +150°C junction temperature - essential for under-hood automotive electronics where ambient temperatures exceed 105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VI(OFF) | ≤ 1.1V - ensures reliable OFF-state at TTL-low inputs (≤0.8V) with margin |
| VI(ON) | ≥ 1.9V - guarantees full turn-on with standard CMOS-high outputs (≥3.3V) |
| VO(ON) | ≤ 0.3V @ 10mA - minimizes power loss and enables clean low-side switching |
| IC(MAX) | 100mA per transistor - supports driving LEDs, relays, or small solenoids directly |
| R1, R2 | 47kΩ ±30% - sets predictable base current without external components |
| fT | 250MHz - supports high-speed digital switching up to ~10MHz edge rates |
| TJ Range | −55°C to +150°C - meets AEC-Q101 thermal stress requirements for automotive use |
Pinout & Package
SOT363 (SC-70-6) surface-mount package: 1.8–2.2mm × 2.0–2.2mm footprint, 0.65mm lead pitch, matte tin-plated leads, moisture sensitivity level 1, UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 4 | Emitter of Q2 | Independent second low-side output; enables dual-channel control |
| 5 | Base of Q2 | Separate input node; allows asynchronous control of Q2 |
| 6 | Collector of Q2 | Second high-side output; electrically isolated from Q1 collector |
Key Features
| Feature | Design Value |

Applications
| Automotive Body Control Module | LED Driver Interface |
|---|---|

IC Role / Device Role / Timing Role: Schmitt-trigger compatible input stage with hysteresis derived from R1/R2 ratio. Use Value: Guaranteed VI(ON)/VI(OFF) separation (>1.4V) prevents chatter in noisy industrial environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2101PT3G | Single NPN pre-biased transistor; no dual configuration | Requires two devices for dual-channel function; larger board area | Select when only one channel is needed or layout allows duplication |
| EMH12T2R | PNP/NPN complementary pair; different polarity and bias topology | Supports high-side switching but lacks matched dual-NPN architecture | Choose for push-pull output stages requiring complementary drive |
Compared with NSVD2101PT3G and EMH12T2R, the ADC144EUQ-13 uniquely delivers matched dual-NPN functionality in one SOT363 package with AEC-Q101 qualification - simplifying design for space-constrained automotive modules requiring two independent low-side switches.

FAQ
What is the maximum allowable voltage across the collector-emitter terminals?
The absolute maximum VCE is not explicitly stated, but VCC = 50V is rated as the maximum supply voltage, and the device is characterized up to that level with IC ≤ 100mA. Operation beyond 50V risks permanent damage and violates AEC-Q101 stress limits.
Can ADC144EUQ-13 be used in non-automotive industrial applications?
Yes - its −55°C to +150°C operating range, 270mW power rating, and RoHS/Green compliance make it suitable for industrial controls, medical instrumentation, and telecom infrastructure where reliability and environmental compliance are required.
Is the 47kΩ bias resistor value fixed or process-trimmed?
The R1 and R2 values are process-defined thin-film resistors with ±30% tolerance, not laser-trimmed. The ratio tolerance is tighter (±20%), ensuring consistent current gain across units, but absolute base current varies within the specified range.
Does the SOT363 package support reflow soldering per J-STD-020?
Yes - the device has Moisture Sensitivity Level 1, meaning it can be subjected to unlimited floor life and standard Pb-free reflow profiles (peak 260°C) without baking, per J-STD-020 requirements.
