Product details
Overview
DDA114YU-7-F from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 10 kΩ and 47 kΩ bias resistors (R1/R2), −50 V VCBO, −70 mA IO, and −0.3 V VCE(sat) at IC/IB = −5 mA/−0.25 mA. It enables compact, reliable level-shifting and digital switching in space-constrained logic interface circuits.
For engineers reviewing the DDA114YU-7-F datasheet, DDA114YU-7-F pinout, DDA114YU-7-F application, or DDA114YU-7-F equivalent, this part serves as a verified dual-channel PNP switch with known resistor ratio tolerance (±20%), AEC-Q101 qualification option (Q-grade), and defined thermal resistance (625 °C/W) for automotive and industrial control designs.
Technical Context
This device integrates two identical PNP transistors sharing common emitter connections and individual base bias networks-each comprising R1 (10 kΩ) and R2 (47 kΩ)-enabling independent switching without external bias components. Its SOT363 footprint supports high-density PCB layouts while maintaining thermal performance up to +150 °C junction temperature.
The dual configuration operates with guaranteed VIN(on) ≤ −1.9 V and VIN(off) ≥ −0.3 V at IO = −1 mA, supporting TTL- and CMOS-compatible input drive levels. Output saturation voltage remains ≤ −0.3 V under 5 mA load, ensuring low conduction loss in active-low switching paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO | −50 V - Withstands reverse collector-base voltage up to 50 V, enabling safe operation in 24 V industrial bus interfaces. |
| IO (max) | −70 mA - Supports driving moderate-current loads such as LED indicators or small relays directly from microcontroller GPIOs. |
| VCE(sat) | ≤ −0.3 V at IC/IB = −5 mA/−0.25 mA - Minimizes power dissipation (< 0.15 mW per channel at 5 mA) in saturated switching mode. |
| R1 / R2 | 10 kΩ / 47 kΩ - Provides fixed base current limiting and ensures predictable turn-on threshold across temperature and process variation. |
| R2/R1 tolerance | ±20% - Maintains consistent current gain stability between channels, critical for matched dual-switch timing in logic translators. |
| PD | 200 mW - Total package power limit; allows dual-channel operation at ≤100 mW per element under FR-4 board conditions. |
| TJ range | −55 °C to +150 °C - Qualified for under-hood automotive and industrial environments where extended thermal cycling occurs. |
Pinout & Package
Package: SOT363 - 6-pin ultra-small surface-mount package (2.15 mm × 2.10 mm × 0.95 mm), green molding compound (UL 94V-0), matte tin-plated leads, moisture sensitivity level 1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA124EU-7-F | Equal R1/R2 = 22 kΩ; lower IO (−30 mA); higher VIN(on) (−1.9 V vs −1.9 V), same VCE(sat). | Optimized for lower-current logic buffering rather than medium-power load switching. | Select when matching bias current to 22 kΩ pull-up networks or when lower power consumption is prioritized over drive strength. |
| DDA123JU-7-F | R1 = 2.2 kΩ, R2 = 47 kΩ; higher IO (−100 mA); VCE(sat) = −0.3 V at −5 mA/−0.25 mA; tighter R2/R1 tolerance (±15%). | Suited for higher-current loads like relay coils or multi-LED strings requiring faster switching. | Choose when driving >70 mA loads or needing improved bias precision for critical timing margins in synchronous logic interfaces. |

FAQ
What is the maximum continuous collector current per channel for DDA114YU-7-F?
The absolute maximum output current per channel is −70 mA, as specified in the Absolute Maximum Ratings table. This value applies under steady-state DC conditions at TA = +25°C with proper PCB thermal relief. Derating is required above +25°C ambient per the 625 °C/W RθJA curve.
Does DDA114YU-7-F support automotive-grade qualification?
Yes-the Q-grade variant DDA114YUQ-7-F is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. The standard DDA114YU-7-F is not automotive-qualified but shares identical die and package construction.
How does the internal resistor network affect input threshold voltage?
The 10 kΩ/47 kΩ R1/R2 divider sets VIN(on) ≈ −1.9 V and VIN(off) ≈ −0.3 V at IO = −1 mA. This provides a well-defined hysteresis window that rejects noise below 1.6 V amplitude while ensuring clean turn-on for standard logic-level inputs.
Can DDA114YU-7-F replace discrete transistor + resistor combinations in existing designs?
Yes-it replaces two PNP transistors and four bias resistors in dual-channel configurations. Pin compatibility with SOT363 layout and identical electrical behavior (VCE(sat), hFE, R1/R2 values) allow drop-in replacement without schematic or layout changes.
