Product details
Overview
DDTA114ECAQ-7-F from Diodes Incorporated is a PNP pre-biased small-signal 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-7-F datasheet, DDTA114ECAQ-7-F pinout, DDTA114ECAQ-7-F application, or DDTA114ECAQ-7-F equivalent, key selection criteria include input voltage range (−40 V to +10 V), output saturation voltage (≤ −0.3 V at −10 mA), DC current gain (GL = 30), 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 use, it meets AEC-Q101 stress testing requirements including HTOL, temperature cycling, and ESD (HBM ≥ 8 kV). Electrical performance is specified across −55 °C to +150 °C, with thermal resistance RθJA = 625 °C/W on FR-4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; supports rail-to-rail switching in 3.3 V/5 V automotive logic systems. |
| IC(max) | −50 mA - Continuous collector current rating; suitable for driving LEDs, small relays, or logic gate inputs. |
| R1 / R2 | 10 kΩ ±30% - Matched internal base bias resistors enabling single-supply inverter operation without external components. |
| VO(on) | ≤ −0.3 V at −10 mA - Low saturation voltage ensures minimal power loss and reliable TTL/CMOS-compatible low-level output. |
| GL | 30 - DC current gain at VCE = −5 V, IC = −5 mA; defines minimum drive capability for load switching. |
| PD | 200 mW - Power dissipation limit on standard FR-4 board; constrains maximum continuous switching frequency and duty cycle. |
| TJ/TSTG | −55 °C to +150 °C - Extended temperature range certified per AEC-Q101; validated for engine bay and infotainment module placement. |
Pinout & Package
Package: SOT23 - surface-mount plastic package with matte tin-plated leads, moisture sensitivity level 1, weight ≈ 0.008 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Connected to system ground or low-side reference; forms common node for current sink operation. |
| 2 (Base) | Input node | Internally connected to both R1 and R2; accepts logic-level input to control transistor conduction. |
| 3 (Collector) | Output node | Provides inverted, current-sinking output; connects to load supply rail (e.g., +3.3 V or +5 V). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 = R2 bias network | 10 kΩ matched resistors reduce BOM count and layout area for inverter/switch functions. |

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-7-F | Same electrical specs, identical R1/R2 = 10 kΩ, but marked as active (not NRND); pinout and package identical. | Recommended for new designs; replaces DDTA114ECAQ-7-F per Diodes' NRND notice. | Select ADTA114ECAQ-7-F for production continuity and long-term availability. |
| DDTA114EKA-7-F | Same die and bias values, but non-automotive grade (no AEC-Q101); same SOT23 package and pinout. | Suitable for commercial/industrial use only; lacks PPAP documentation and extended temperature validation. | Choose only if AEC-Q101 compliance is not required and cost optimization is critical. |
Compared with DDTA114ECAQ-7-F, ADTA114ECAQ-7-F offers identical performance with full production support, while DDTA114EKA-7-F trades automotive qualification for lower cost in non-automotive systems-making ADTA114ECAQ-7-F the preferred upgrade path.

FAQ
Is DDTA114ECAQ-7-F still recommended for new designs?
No. Diodes Incorporated marks DDTA114ECAQ-7-F as NRND (Not Recommended for New Design) and recommends ADTA114ECAQ-7-F as its direct replacement. Both share identical electrical characteristics, package, and marking code P13, but ADTA114ECAQ-7-F is actively supported with full AEC-Q101 documentation and long-term supply assurance.
What is the function of the internal R1 = R2 resistor network?
The integrated 10 kΩ R1 and R2 resistors form a voltage divider that biases the PNP transistor's base, enabling inverter operation with a single input pin. R1 connects base to input, R2 connects base to emitter-this configuration provides predictable turn-on/off thresholds and eliminates external bias components in digital switching circuits.
Can DDTA114ECAQ-7-F be used in place of a standard PNP BJT like MMBT3906?
Yes, but only when the application benefits from integrated biasing. Unlike MMBT3906, DDTA114ECAQ-7-F requires no external base resistors for basic inverter use. However, it lacks flexibility for adjustable bias or linear amplification-its design intent is strictly digital switching, not analog gain stages.
What does the "Q" suffix indicate in DDTA114ECAQ-7-F?
The "Q" denotes automotive qualification per AEC-Q101 standards. It signifies that the device has passed stress tests including high-temperature operating life, temperature cycling, and electrostatic discharge (HBM ≥ 8 kV), and is PPAP-capable with full traceability for automotive production programs.
