Product details
Overview
ADTA114EUAQ from Diodes Incorporated is a PNP pre-biased small-signal transistor in SOT323 package, featuring integrated 10 kΩ base-emitter and base-collector bias resistors, −100 mA maximum collector current, −50 V VCEO, and AEC-Q101 qualification for automotive applications such as LED load switching and sensor interface circuits.
For engineers reviewing the ADTA114EUAQ datasheet, ADTA114EUAQ pinout, ADTA114EUAQ application, or ADTA114EUAQ equivalent, key selection criteria include its built-in resistor ratio tolerance (±20%), DC current gain (hFE ≥ 30), −1.9 V typical input threshold at −10 mA output, and thermal resistance of 375 °C/W on FR4 board.
Technical Context
This device integrates two precision-matched 10 kΩ biasing resistors (R1 = R2) to eliminate external components in digital switching configurations. Its PNP topology enables high-side load control with logic-level input compatibility down to −1.1 V (VL(OFF)) and −3.0 V (VL(ON)) thresholds.
The transistor operates across −55 °C to +150 °C, supports transient pulse power up to 0.4 W at 100 µs, and delivers 250 MHz fT at −10 V VCE, enabling reliable performance in automotive body electronics and industrial I/O conditioning where space-constrained, lead-free, and PPAP-capable solutions are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum allowable collector-emitter voltage before breakdown in open-base configuration. |
| IC(max) | −100 mA: Continuous collector current limit defining maximum switched load capacity. |
| R1 / R2 | 10 kΩ each: Integrated base bias network eliminates need for external resistors in digital driver designs. |
| hFE | ≥30 at −5 V VCE, −5 mA IC: Minimum DC current gain ensuring stable saturation under typical drive conditions. |
| fT | 250 MHz: Gain-bandwidth product confirming suitability for medium-speed switching (≤10 MHz edge rates). |
| PD | 330 mW: Power dissipation limit on standard FR4 PCB, derating linearly above +25 °C ambient. |
| RθJA | 375 °C/W: Thermal resistance from junction to ambient, used to calculate max operating temperature rise. |
Pinout & Package
Package: SOT323 - surface-mount, 3-terminal plastic case with 0.65 mm lead pitch, UL 94V-0 rated molding compound, and matte tin-plated leads compliant with MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Connected to supply rail in high-side switch; carries full load current. |
| 2 (Base) | Input node | Accepts logic-level control signal; internally connected to both bias resistors. |
| 3 (Collector) | Output node | Switches load to ground; configured for common-emitter operation with inverted logic. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Integrated R1/R2 = 10 kΩ | Reduces BOM count by two resistors and associated layout area in discrete logic-level interface circuits. |
| ±20% R2/R1 tolerance | Ensures consistent turn-on/turn-off behavior across production lots without calibration. |
| −0.3 V VO(ON) max | Guarantees low saturation voltage at −10 mA output, minimizing power loss in load-switching applications. |
| Moisture Sensitivity Level 1 | Enables direct placement without baking, reducing manufacturing overhead in automated SMT lines. |
Applications
| Automotive Interior Lighting Control | Industrial Digital I/O Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV114EUAZT1G | Same SOT323 package, identical R1/R2 = 10 kΩ, but rated only to +125 °C TJ(max) (vs. +150 °C). | Not AEC-Q101 qualified; suitable for commercial/industrial use only. | Select when automotive qualification is unnecessary and cost sensitivity outweighs extended temperature margin. |
| DXTA114ECA-7 | SOT23 package, same electrical specs, but higher RθJA = 450 °C/W and no AEC-Q101 validation. | Larger footprint than SOT323; lacks PPAP documentation support for Tier 1 automotive programs. | Choose for legacy SOT23 layouts where board rework is prohibitive, accepting reduced thermal performance. |
Compared with NSV114EUAZT1G and DXTA114ECA-7, ADTA114EUAQ uniquely combines AEC-Q101 qualification, +150 °C operation, and SOT323 miniaturization-making it the only option for space-constrained, thermally demanding automotive modules requiring PPAP traceability.

FAQ
What is the maximum safe operating voltage between collector and emitter?
The ADTA114EUAQ has an absolute maximum VCEO rating of −50 V. This means the collector-to-emitter voltage must not exceed −50 V under any condition, including transients. Exceeding this value risks permanent breakdown. Derating is recommended for long-term reliability in high-voltage automotive environments.
Can this transistor be used in a common-emitter configuration with 5 V logic input?
Yes-its input threshold VL(ON) is −1.9 V (typical) at −10 mA output, making it compatible with 5 V logic when referenced to a negative rail or used with level-shifting. For 3.3 V microcontrollers, ensure the input signal swings below −1.1 V (VL(OFF)) to guarantee full turn-off.
Does the ±20% R2/R1 tolerance affect switching speed consistency?
No-the R2/R1 ratio tolerance governs DC bias point stability, not switching speed. Rise/fall times are primarily determined by junction capacitance (COBO ≈ 10 pF at 1 MHz) and fT (250 MHz), both specified independently of resistor matching. The ±20% ensures predictable saturation behavior across temperature and process variation.
Is the SOT323 package compatible with standard reflow profiles for lead-free soldering?
Yes-the ADTA114EUAQ's SOT323 package is fully RoHS-compliant and qualified for lead-free reflow per J-STD-020. Its moisture sensitivity level is 1, allowing exposure to ambient conditions indefinitely without baking prior to assembly.
