Product details
Overview
DDA114EUQ-7-F from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 10 kΩ input resistors (R1 = R2), −50 V VCEO, −50 mA IO, and AEC-Q101 qualification for automotive signal switching. It operates as a compact, bias-resistor-equipped digital switch pair for low-power logic-level interfacing in body control modules and LED drivers.
For engineers reviewing the DDA114EUQ-7-F datasheet, DDA114EUQ-7-F pinout, DDA114EUQ-7-F application, or DDA114EUQ-7-F equivalent, key selection criteria include guaranteed VI(ON) ≤ −1.9 V at −10 mA output, VCE(sat) ≤ −0.3 V, R1/R2 matching tolerance (±20%), and IATF 16949-manufactured traceability for automotive-grade reliability.
Technical Context
This device integrates two identical PNP bipolar transistors with monolithically embedded base-emitter bias resistors (R1 = R2 = 10 kΩ) in a single SOT363 package. Each channel supports independent switching with guaranteed DC current gain (GL) of 30 at −5 mA output and −5 V VO.
Designed for direct TTL/CMOS-compatible input drive, it eliminates external bias components while maintaining thermal stability across −55°C to +150°C operating range. Its −200 mW total power dissipation (150 mW per element max) and 625°C/W θJA are validated on FR-4 PCB with minimum recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with safety margin. |
| IO | −50 mA - Guaranteed continuous output current per channel; sufficient for driving small relays or LED strings. |
| VCE(sat) | ≤ −0.3 V @ IC/IB = −10 mA / −1 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| R1, R2 | 10 kΩ ±30% - Integrated bias resistors eliminate external components and reduce BOM count for digital interface circuits. |
| GL | 30 min @ VO = −5 V, IO = −5 mA - Confirmed current gain ensures reliable turn-on under worst-case temperature and process variation. |
| θJA | 625°C/W - Thermal resistance measured on standard FR-4 board; informs heatsinking requirements for sustained 150 mW/channel operation. |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, lead-free, halogen-free plastic package with matte tin-plated leads; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of Transistor 1 | Common emitter connection point for first PNP switch; referenced to system ground in high-side switch configuration. |
| 2 | Base of Transistor 1 | Input node with internal 10 kΩ resistor to emitter (Pin 1); accepts logic-low active control signals. |
| 3 | Collector of Transistor 1 | Output node for first channel; sinks current when transistor is saturated (e.g., drives load to VCC). |
| 4 | Emitter of Transistor 2 | Emitter of second independent PNP switch; electrically isolated from Pin 1 but shares same package thermal mass. |
| 5 | Base of Transistor 2 | Second input node with identical 10 kΩ bias network; enables dual-channel synchronous or independent control. |
| 6 | Collector of Transistor 2 | Second output node; supports redundant or complementary switching functions without cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and body electronics per stress test requirements. |
| Integrated R1/R2 = 10 kΩ | Eliminates four external resistors per dual channel, reducing PCB area by ≥1.2 mm² and assembly cost. |
| −55°C to +150°C operation | Supports under-hood and cabin-mounted modules without derating up to maximum ambient temperature. |
| SOT363 footprint compatibility | Shares land pattern with industry-standard dual-transistor packages (e.g., DDC114EUQ), enabling drop-in layout reuse. |
| RoHS 3 & "Green" compliant | Meets EU Directive 2015/863/EU with Br+Cl < 1500 ppm and Sb < 1000 ppm; suitable for global automotive OEMs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA114EU-7-F | No Q suffix; same electrical specs but not PPAP-capable or AEC-Q101 certified. | Restricted to non-automotive industrial or consumer use where change control and automotive qualification are not required. | Select only if automotive qualification is unnecessary and cost sensitivity outweighs supply chain traceability needs. |
| ADA114EUQ | NRND replacement part with identical pinout, R1/R2 values, and AEC-Q101 status; updated die revision. | Same automotive application scope; intended for new designs requiring continued supply assurance beyond DDA114EUQ-7-F's NRND status. | Preferred for new automotive designs due to active status and guaranteed long-term availability. |
Compared with DDA114EUQ-7-F, DDA114EU-7-F lacks PPAP documentation and automotive change control, while ADA114EUQ offers identical functionality with assured future supply-making it the recommended upgrade path for production programs.

FAQ
Is DDA114EUQ-7-F pin-compatible with DDA114EU-7-F?
Yes, both share identical SOT363 pinout, electrical specifications, and thermal characteristics. The only differences are qualification status (AEC-Q101/PPAP for DDA114EUQ-7-F) and packaging marking (P13 vs. P13). No PCB redesign is needed when upgrading from DDA114EU-7-F to DDA114EUQ-7-F.
What does the "Q" suffix indicate in DDA114EUQ-7-F?
The "Q" suffix denotes automotive qualification: AEC-Q101 stress-tested, PPAP-capable, and manufactured in IATF 16949-certified facilities. It also signifies controlled change management and extended traceability documentation required by Tier 1 automotive suppliers.
Can DDA114EUQ-7-F replace DDC114EUQ-7-F in a design?
No-DDC114EUQ-7-F is the complementary NPN version. Swapping would invert logic polarity and violate bias network topology. For NPN functionality, use DDC114EUQ-7-F; for PNP, DDA114EUQ-7-F remains correct. Cross-type substitution requires circuit redesign.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C. With θJA = 625°C/W and 150 mW per element, sustained operation at ambient temperatures above +75°C requires thermal relief (e.g., copper pour, airflow) to avoid exceeding TJ(max) under full load conditions.
