Product details
Overview
DDA123JU-7 from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 2.2 kΩ and 47 kΩ bias resistors, −50 V VCBO, −100 mA IO max, and −0.3 V VCE(sat) at −5 mA/−0.25 mA. It serves as a compact, space-saving logic-level interface and load switch for low-power digital control circuits.
For engineers reviewing the DDA123JU-7 datasheet, DDA123JU-7 pinout, DDA123JU-7 application, or DDA123JU-7 equivalent, this device is selected for its guaranteed resistor tolerance (±30%), AEC-Q101 qualification option (DDA123JUQ), low saturation voltage, and dual-element integration in a 6-pin SOT363 footprint - critical for automotive body electronics and industrial I/O modules.
Technical Context
This dual PNP transistor integrates two independent pre-biased elements sharing no internal connection - each with its own R1 (2.2 kΩ) and R2 (47 kΩ) network to enable direct TTL/CMOS-compatible switching without external base resistors. The structure supports discrete logic inversion and current-sinking output stages.
Each channel operates with −50 V collector-base breakdown, −100 mA absolute maximum output current, and thermal resistance of 625 °C/W on FR-4 PCBs. Its −55 °C to +150 °C operating range and green RoHS-compliant construction align with automotive and industrial reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO | −50 V - Ensures safe operation with up to 50 V reverse bias across collector-base junctions. |
| IO (max) | −100 mA - Supports driving moderate-current loads like LEDs, relays, or gate inputs without external amplification. |
| VCE(sat) | −0.3 V @ −5 mA/−0.25 mA - Minimizes power loss and heat generation in saturated switching applications. |
| R1/R2 | 2.2 kΩ / 47 kΩ - Provides fixed, factory-trimmed biasing for predictable turn-on threshold and gain stability. |
| R1 Tolerance | ±30% - Guarantees functional operation across process variation without requiring system-level recalibration. |
| PD | 200 mW - Limits total dissipation per package, enabling use in dense PCB layouts with minimal thermal derating. |
| TJ Range | −55 °C to +150 °C - Validated for under-hood automotive and industrial ambient environments. |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, lead-free, halogen-free molded plastic package with 0.65 mm pitch, 2.15 mm × 2.10 mm body size, and 0.95 mm height. Moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (Channel 1) | Common emitter node for first PNP transistor; connects to load return path. |
| 2 | Base (Channel 1) | Internally connected to R1 and R2; accepts logic-level input signal. |
| 3 | Collector (Channel 1) | Current-sinking output terminal for first channel; ties to VCC via load. |
| 4 | Collector (Channel 2) | Current-sinking output terminal for second channel; electrically isolated from Pin 3. |
| 5 | Base (Channel 2) | Internally connected to R1 and R2 of second channel; independent input node. |
| 6 | Emitter (Channel 2) | Common emitter node for second PNP transistor; separate return path from Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent PNP channels | Two fully isolated pre-biased transistors in one SOT363 - reduces board area vs. discrete solutions by >40%. |
| Built-in bias resistors (2.2kΩ/47kΩ) | Eliminates need for four external resistors per channel, simplifying layout and improving BOM consistency. |
| AEC-Q101 qualified variant available | DDA123JUQ-7 meets automotive stress testing standards for temperature cycling, HTRB, and ESD robustness. |
| Green, RoHS-compliant construction | Meets EU Directive 2015/863/EU with <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - suitable for eco-sensitive end markets. |
| Low VCE(sat) at rated current | −0.3 V ensures <150 µW static power loss per channel at 5 mA - critical for battery-powered sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased dual PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA114YU-7-F | R1/R2 = 10 kΩ/47 kΩ; higher input impedance; lower IO (−70 mA) | Better suited for high-impedance logic interfaces where drive strength is secondary to noise immunity | Select when interfacing with weak-drive MCUs or where reduced base current minimizes supply loading |
| DDA144EU-7-F | R1/R2 = 47 kΩ/47 kΩ; symmetric bias; lower gain (GL = 68); same VCE(sat) | Optimized for matched channel behavior in differential or mirrored switching topologies | Choose for balanced dual-channel designs such as complementary enable/disable pairs or redundant outputs |
Compared with DDA123JU-7, DDA114YU-7-F trades drive strength for higher input impedance, while DDA144EU-7-F prioritizes channel symmetry over raw current capability - making DDA123JU-7 optimal for asymmetric, high-current sinking in cost- and space-constrained I/O expansion.

FAQ
What is the maximum continuous output current per channel for DDA123JU-7?
The absolute maximum output current per channel is −100 mA, verified per Absolute Maximum Ratings table in DS30346 Rev. 14-2. Derating is required above +25°C ambient: power dissipation drops linearly to zero at +150°C, with 625 °C/W thermal resistance on standard FR-4 PCBs.
Does DDA123JU-7 have automotive qualification?
The base part DDA123JU-7 is not AEC-Q101 qualified, but its automotive-grade variant DDA123JUQ-7 is fully qualified, PPAP-capable, and manufactured in IATF 16949-certified facilities. The Q-suffix denotes compliance with automotive change control and extended reliability testing.
How are the two channels electrically isolated in the SOT363 package?
Channels are fully independent: Pins 1–3 form Channel 1 (E-B-C), Pins 4–6 form Channel 2 (C-B-E), with no internal connection between them. Electrical isolation is confirmed by the schematic diagram and pin numbering in DS30346, and validated by separate VCE(sat) and leakage measurements per channel.
Can DDA123JU-7 replace a discrete PNP + two resistors in existing designs?
Yes - it directly replaces one PNP transistor plus two base resistors per channel, using identical SOT363 footprint and matching pinout conventions. Designers must verify that 2.2 kΩ/47 kΩ bias values meet their target hFE and switching speed requirements, as shown in Figures 5–6 of the datasheet.
