Product details
Overview
ADTA114ECAQ-13 from Diodes Incorporated is a PNP pre-biased small-signal transistor in SOT23 package, featuring integrated bias resistors (R1 = R2 = 10 kΩ), AEC-Q101 qualification for automotive use, and −50 V VCC rating. It delivers −100 mA IC(max), −50 mA IO, and 250 MHz fT, enabling compact high-reliability switching in body control modules and LED drivers.
For engineers reviewing the ADTA114ECAQ-13 datasheet, ADTA114ECAQ-13 pinout, ADTA114ECAQ-13 application, or ADTA114ECAQ-13 equivalent, key selection criteria include guaranteed ON/OFF thresholds (VI(ON) ≤ −3 V, VI(OFF) ≥ −0.5 V), ±30% input resistor tolerance, and thermal derating on FR-4 boards up to +150 °C junction temperature.
Technical Context
This device integrates two matched 10 kΩ bias resistors (R1 = R2) directly into a PNP epitaxial planar transistor die, eliminating external base resistors and reducing PCB footprint. Its guaranteed switching thresholds (VI(ON) ≤ −3 V at IO = −10 mA; VI(OFF) ≥ −0.5 V at IO = −100 μA) ensure robust digital interface compatibility with 3.3 V/5 V logic families driving negative-voltage loads.
The SOT23 package supports surface-mount assembly with JEDEC-standard lead finish and moisture sensitivity level 1. Thermal performance is characterized for minimum-copper FR-4 board mounting: RθJA = 403 °C/W and 310 mW PD at TA = +25 °C, with linear derating above +25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Max | −50 V: Supports high-side switching in 24 V automotive systems with margin against load-dump transients. |
| R1 / R2 Nominal | 10 kΩ ±30%: Enables direct logic-level drive without external bias network; ratio tolerance ±20% ensures consistent β-dependent gain stability. |
| IC(max) | −100 mA: Sufficient for driving relays, small solenoids, or LED strings in body electronics. |
| VO(ON) | −0.1 to −0.3 V @ IO = −10 mA: Low saturation voltage minimizes power loss and heat generation in continuous conduction mode. |
| fT | 250 MHz: Enables stable operation in PWM-driven applications up to ~10–20 MHz switching frequencies with adequate gain margin. |
| TJ Range | −55 to +150 °C: Qualified for under-hood automotive environments per AEC-Q101, including engine control units and lighting modules. |
Pinout & Package
SOT23 plastic surface-mount package with matte tin-plated leads, UL 94V-0 flammability rating, and 0.008 g mass. Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal | Connected to positive rail in high-side switch configuration; must be tied to VCC or higher potential than base. |
| 2 (Base) | Bias input node | Internally connected to both R1 (to emitter) and R2 (to collector); accepts logic-level control signal referenced to emitter. |
| 3 (Collector) | Switched output terminal | Drives load to ground when active; supports −50 mA continuous output current with < −0.3 V saturation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched R1 = R2 = 10 kΩ eliminates two external resistors, reducing BOM count and layout area by >30% vs discrete PNP + resistors. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, ESD, and mechanical shock testing-required for body control, lighting, and HVAC modules. |
| Guaranteed switching thresholds | VI(ON) ≤ −3 V and VI(OFF) ≥ −0.5 V ensure unambiguous logic-level compatibility with standard CMOS/TTL outputs across temperature and supply variation. |
| Green construction | Halogen- and antimony-free molding compound (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) meets global environmental compliance mandates including RoHS 2 and ELV. |
Applications
| Automotive Body Control Module | LED Tail Light Driver |
|---|---|
Use Scenario: Switching 12 V loads such as door lock actuators and window lift motors in centralized body controllers. IC Role / Device Role / Timing Role: High-side PNP switch controlled by microcontroller GPIO with integrated biasing.

IC Role / Device Role / Timing Role: Active-low open-collector interface buffer with defined threshold hysteresis. Use Value: Guaranteed VI(OFF) ≥ −0.5 V prevents false triggering from noise; ±20% R2/R1 tolerance maintains consistent trip point across production lots. | Use Scenario: Converting 3.3 V logic outputs to −5 V compatible levels for legacy industrial communication interfaces. IC Role / Device Role / Timing Role: Inverting level translator with fixed gain and rail-to-rail output swing. Use Value: 250 MHz fT supports clean edge transitions up to 10 MHz data rates; low COBO (<10 pF) preserves signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSV114ECAQ-13 | Same R1/R2 = 10 kΩ, identical SOT23 pinout, but rated only to +125 °C TJ (not AEC-Q101 qualified). | Not approved for automotive production; suitable for industrial or consumer applications where AEC-Q101 is not mandated. | Select if cost sensitivity outweighs automotive qualification requirements and operating temperature stays ≤ +125 °C. |
| DST3904T-7 | PNP pre-biased with R1 = 10 kΩ, R2 = 10 kΩ, but specified for −60 V VCEO and −200 mA IC; no AEC-Q101 claim. | Higher voltage/current capability enables use in 48 V mild-hybrid subsystems, but lacks PPAP documentation support. | Choose when extended voltage margin or higher current drive is required, and automotive process validation is handled externally. |
Compared with NSV114ECAQ-13 and DST3904T-7, ADTA114ECAQ-13 uniquely combines AEC-Q101 qualification, guaranteed −50 V VCC, and full PPAP capability-making it the only drop-in option for Tier 1 automotive production requiring traceable process control and temperature resilience to +150 °C.

FAQ
What is the maximum continuous collector current for ADTA114ECAQ-13?
The absolute maximum continuous collector current (IC) is −100 mA, tested at TA = +25 °C with derating applied above that temperature. At IO = −50 mA, VO(ON) remains ≤ −0.3 V, confirming safe operation within its SOA envelope on standard FR-4 PCBs.
Does ADTA114ECAQ-13 require external base resistors?
No. It integrates two precision-matched 10 kΩ bias resistors (R1 = R2) internally, connecting emitter to base and base to collector. This eliminates the need for external bias components, simplifying layout and improving consistency across production units.
Can ADTA114ECAQ-13 be used in non-automotive applications?
Yes. While AEC-Q101 qualified and marked "Automotive", its electrical and thermal specifications-including −55 to +150 °C operating range, green packaging, and 310 mW power dissipation-are fully applicable to industrial, medical, and telecom equipment where high reliability and environmental compliance are required.
What is the meaning of the marking "2C0" on the device top?
"2C0" is the product type marking code for ADTA114ECAQ-13 in SOT23 package. It appears alongside the date code (e.g., "E9" for September 2017) and is used for traceability and visual identification during assembly and inspection per Diodes Incorporated's standard marking convention.
