Product details
Overview
DDTA114ECAQ-13-F from Diodes Incorporated is a PNP pre-biased small-signal surface-mount transistor in SOT23 package, featuring integrated bias resistors R1 = R2 = 10 kΩ, −50 V VCEO, −50 mA IC(max), and AEC-Q101 qualification for automotive applications. It functions as a digital switch or level translator in low-power logic interface circuits.
For engineers reviewing the DDTA114ECAQ-13-F datasheet, DDTA114ECAQ-13-F pinout, DDTA114ECAQ-13-F application, or DDTA114ECAQ-13-F equivalent, key selection criteria include input voltage range (−40 V to +10 V), guaranteed DC current gain (GL = 30 min at IO = −5 mA), output saturation voltage (VCE(sat) ≤ −0.3 V), and automotive-grade reliability under −55 °C to +150 °C operation.
Technical Context
This device integrates two matched 10 kΩ bias resistors (R1 = R2) to configure a single-transistor inverter with fixed base biasing-eliminating external components for digital switching. Its PNP topology enables active-low signal inversion with grounded emitter configuration.
Designed for automotive-compliant logic interfacing, it supports rail-to-rail input swing (−40 V to +10 V) and delivers stable −50 mA output sink capability at VCC = −50 V, with thermal resistance RθJA = 625 °C/W on FR-4 PCBs using minimum pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter blocking voltage before breakdown; defines safe operating range in high-side switch or level-shifting configurations. |
| IC(max) | −50 mA - Continuous collector current rating; sets maximum load drive capability in digital output stages. |
| R1 = R2 | 10 kΩ ±30% - Matched internal base bias resistors enabling self-biased inverter operation without external components. |
| GL | 30 (min) - DC current gain at VO = −5 V, IO = −5 mA; ensures reliable saturation under defined load conditions. |
| VCE(sat) | ≤ −0.3 V @ IO = −10 mA - Low saturation voltage minimizes power loss and ensures clean logic-low output in switching applications. |
| PD | 200 mW - Maximum power dissipation on FR-4 board; constrains thermal design for continuous operation at ambient up to +85 °C. |
| TJ/TSTG | −55 °C to +150 °C - Extended temperature range validated per AEC-Q101; suitable for under-hood automotive modules. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3 terminals, moisture sensitivity level 1 (J-STD-020), matte tin-plated leads, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Connected to system ground or low-side reference; forms common node for current sinking operation. |
| 2 (Base) | Input node via R1/R2 network | Accepts logic-level input; internal resistor divider sets base bias point for predictable turn-on/turn-off thresholds. |
| 3 (Collector) | Output node | Sinks current to load; output polarity is inverted relative to input (active-low switching behavior). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 = R2 bias network | 10 kΩ matched resistors eliminate need for external base bias components, reducing BOM count and PCB area. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and infotainment interfaces. |
| Green, halogen-free construction | Meets RoHS 3 (2015/863/EU) and Diodes Inc.'s "Green" standard (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb). |
| SOT23 footprint compatibility | Standardized 3-pin SOT23 outline enables drop-in replacement with other logic transistors in space-constrained designs. |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |
|---|---|
Use Scenario: Driving LED status indicators and relay coils from microcontroller GPIO pins in door module ECUs. IC Role / Device Role / Timing Role: Digital switch translating 3.3 V/5 V logic outputs into −12 V sink paths for automotive loads. Use Value: Eliminates discrete resistor networks while maintaining AEC-Q101 reliability and −40 V input tolerance for battery transient immunity. |
Use Scenario: Isolating field sensor signals (e.g., limit switches, proximity sensors) from 24 V DC industrial control inputs. IC Role / Device Role / Timing Role: Level-shifting and noise-immune signal conditioning stage converting 24 V field signals to 5 V logic-compatible levels. Use Value: Built-in 10 kΩ bias resistors ensure stable switching thresholds across temperature, reducing susceptibility to EMI-induced false triggers. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Logic Interface |
Use Scenario: Controlling power-enable lines for auxiliary subsystems (e.g., display backlight, fan drivers) in smart home appliances. IC Role / Device Role / Timing Role: Active-low enable gate with fast turn-on (tON < 100 ns typical) and low VCE(sat) for minimal voltage drop. Use Value: Delivers consistent −0.3 V saturation at −10 mA, ensuring downstream regulators receive clean enable signals without margin loss. |
Use Scenario: Interfacing isolated analog front-end ICs with microcontroller-based data acquisition units in portable diagnostic devices. IC Role / Device Role / Timing Role: Signal inversion and voltage translation between mixed-supply domains (e.g., ±5 V analog section to 3.3 V digital core). Use Value: Guaranteed GL ≥ 30 and −55 °C to +150 °C operation support long-term stability in battery-powered, thermally unregulated enclosures. |
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 |
|---|---|---|---|
| ADTA114ECAQ-13-F | Same electrical specs and package; marked as recommended replacement per Diodes Inc. ordering table (NRND status of DDTA114ECAQ-13-F). | Identical AEC-Q101 qualification and marking code (P13); intended for new automotive designs where DDTA114ECAQ-13-F is NRND. | Select ADTA114ECAQ-13-F for new designs requiring long-term supply continuity and full automotive PPAP support. |
| DDTA114ECA-7-F | Same die and bias values (R1=R2=10 kΩ), but packaged in 3,000-unit 7-inch reel; non-automotive grade (no AEC-Q101 marking). | Approved for industrial/commercial use only; lacks PPAP documentation and automotive traceability requirements. | Choose DDTA114ECA-7-F for cost-sensitive, non-automotive applications where AEC-Q101 compliance is not required. |

FAQ
Is DDTA114ECAQ-13-F pin-compatible with DDTA114ECA-7-F?
Yes-both share identical SOT23 pinout (Emitter–Base–Collector on pins 1–2–3) and electrical characteristics. The only differences are packaging (10,000-unit 13-inch reel vs. 3,000-unit 7-inch reel) and compliance status (AEC-Q101 automotive vs. commercial grade).
What does the 'Q' suffix indicate in DDTA114ECAQ-13-F?
The 'Q' suffix denotes automotive qualification per AEC-Q101 standards and PPAP capability. It also signifies green, halogen-free construction compliant with RoHS 3 and Diodes Inc.'s "Green" material definition.
Can DDTA114ECAQ-13-F be used in 3.3 V logic systems?
Yes-it supports input voltages from +10 V to −40 V, making it compatible with 3.3 V, 5 V, and 12 V logic families. At VI = −3.3 V, it reliably sinks ≥10 mA with VCE(sat) ≤ −0.25 V, confirmed by typical characteristic curves in DS30333 Rev. 10-2.
Why is DDTA114ECAQ-13-F marked NRND?
Diodes Incorporated lists DDTA114ECAQ-13-F as Not Recommended for New Design because ADTA114ECAQ-13-F is its designated replacement-offering identical performance with enhanced long-term supply assurance and updated automotive qualification documentation.
