Product details
Overview
DDA114EU-7 from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 10kΩ base-emitter and 10kΩ base-collector bias resistors. It delivers −50mA output current, −0.3V VCE(sat) at −10mA/−1mA drive, and operates across −55°C to +150°C for automotive signal switching applications.
For engineers reviewing the DDA114EU-7 datasheet, DDA114EU-7 pinout, DDA114EU-7 application, or DDA114EU-7 equivalent, this device serves as a compact, AEC-Q101-capable solution for level-shifting, logic interfacing, and discrete load control where low saturation voltage and built-in biasing reduce external component count.
Technical Context
This dual PNP transistor integrates two identical pre-biased elements sharing common emitter terminals (pins 1 & 3), each with matched R1 = R2 = 10kΩ ±30% bias resistors. Its design eliminates need for external base resistors in digital input buffering and open-collector output translation circuits.
Each channel supports −50mA continuous output current with −0.3V saturation voltage at IC/IB = −10mA/−1mA, and exhibits −50V VCEO breakdown rating. Thermal resistance is 625°C/W on FR-4 PCB, limiting power dissipation to 200mW total (150mW per element).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50V - Withstands up to −50V collector-to-emitter voltage before breakdown, enabling use in 24V industrial bus interfaces. |
| IO(max) | −50mA - Maximum continuous output current per channel, suitable for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | −0.3V @ −10mA/−1mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| R1 / R2 | 10kΩ ±30% - Integrated bias resistors eliminate external components for digital input conditioning and pull-up/pull-down functions. |
| PD | 200mW - Total package power dissipation limit; requires thermal-aware PCB layout to avoid exceeding 150mW per transistor element. |
| TJ Range | −55°C to +150°C - Qualified for under-hood automotive environments and industrial control systems with wide ambient swings. |
Pinout & Package

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 |
|---|---|---|---|
| DDA114YU-7-F | R1 = 10kΩ, R2 = 47kΩ - asymmetric bias network yields higher input impedance and lower base current draw. | Better suited for high-impedance MCU inputs where base loading must be minimized; less ideal for fast-switching loads. | Select when input drive capability is limited and leakage-sensitive logic levels are required. |
| DDA124EU-7-F | R1 = R2 = 22kΩ - higher resistance values reduce base current but increase VIN(on) threshold to −1.9V. | Requires stronger negative input swing to activate; less compatible with weak-drive sources like optocouplers or open-drain buffers. | Choose for reduced power consumption in battery-powered nodes where slower edge rates are acceptable. |
Compared with DDA114YU-7-F and DDA124EU-7-F, DDA114EU-7 offers balanced 10kΩ biasing for optimal trade-off between input sensitivity, saturation performance, and noise immunity-making it the preferred choice for general-purpose automotive and industrial digital interfacing.

FAQ
What is the maximum allowable junction temperature for DDA114EU-7?
The absolute maximum junction temperature is +150°C, consistent with its AEC-Q101 qualification and −55°C to +150°C operating range. Derating begins at +25°C ambient, with thermal resistance of 625°C/W requiring careful PCB copper area allocation to maintain safe junction temperatures under full 200mW load.
Can DDA114EU-7 replace a standard PNP transistor like BC857 in existing designs?
Yes, but only if the circuit relies on external base resistors. DDA114EU-7 integrates 10kΩ R1 and R2, so direct substitution requires removing those external resistors and verifying that the resulting base current and switching speed meet timing requirements-especially critical in high-frequency digital interfaces.
Is DDA114EU-7 suitable for bidirectional signal translation?
No-it is a unidirectional PNP switch optimized for sinking current from a positive rail to ground. Its internal resistor topology and polarity prevent reverse conduction; for bidirectional level shifting, dedicated analog switches or MOSFET-based solutions are required.
Does DDA114EU-7 have any built-in ESD protection?
No explicit on-chip ESD protection diodes are specified in the datasheet. System-level ESD protection (e.g., external TVS diodes) is recommended for applications exposed to IEC 61000-4-2 events, particularly in automotive and industrial environments where contact discharge exceeds ±8kV.
