Product details
Overview
DDA123JH-7 from Diodes Incorporated is a PNP pre-biased dual small-signal transistor in SOT563 package, featuring integrated 2.2kΩ and 47kΩ bias resistors, -50V VCBO/VCEO, -100mA IO max, and AEC-Q101 qualification for automotive reliability. It functions as a dual-channel logic-level switch in low-power interface circuits.
For engineers reviewing the DDA123JH-7 datasheet, DDA123JH-7 pinout, DDA123JH-7 application, or DDA123JH-7 equivalent, key selection criteria include input voltage thresholds (VL(OFF) = -0.5V, VL(ON) = -1.9V), output saturation voltage (-0.3V), DC current gain (GL = 80), and AEC-Q101 compliance for automotive signal conditioning.
Technical Context
This dual PNP transistor integrates two independent pre-biased channels with separate R1 (2.2kΩ) and R2 (47kΩ) resistors per channel, enabling direct TTL/CMOS-compatible switching without external bias networks. Each channel supports -100mA output current and operates within -55°C to +150°C ambient range.
The device uses epitaxial planar die construction and achieves -0.3V VCE(SAT) at IC/IB = -5mA/-0.25mA, with hFE = 100–600 at IC = -1mA and VCE = -5V. Its 150mW power dissipation and 833°C/W RθJA are specified on FR4 board with recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO/VCEO | -50V - Withstands reverse collector-base/emitter breakdown up to 50V, suitable for 24V automotive supply rail interfacing. |
| IO (max) | -100mA - Supports driving medium-current loads such as LED indicators or small relays directly from logic outputs. |
| VCE(SAT) | -0.3V @ IC/IB = -5mA/-0.25mA - Minimizes conduction loss and self-heating in always-on or pulsed switching applications. |
| R1 / R2 | 2.2kΩ / 47kΩ - Provides fixed base bias ratio for predictable turn-on at -1.9V input, eliminating discrete resistor placement. |
| GL | 80 - Delivers stable current gain under VO = -5V, IO = -10mA conditions, ensuring reliable digital switching margin. |
| PD | 150mW - Enables operation in space-constrained SOT563 footprint without forced air or heatsinking in ambient ≤75°C. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronics including temperature cycling, HTRB, and ESD. |
Pinout & Package
SOT563 surface-mount package: 6-pin, 2.2mm × 1.35mm × 0.6mm body, matte tin-plated copper leadframe, moisture sensitivity level 1, UL 94V-0 rated mold compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (Channel 1) | Common emitter node for first PNP transistor; connects to load return path in high-side switch configuration. |
| 2 | Base (Channel 1) | Internally connected to R1 (2.2kΩ) and R2 (47kΩ); accepts logic-level input to control Channel 1 conduction. |
| 3 | Collector (Channel 1) | Output node for Channel 1; sinks current when active, used for driving loads referenced to VCC. |
| 4 | Emitter (Channel 2) | Emitter node for second independent PNP transistor; electrically isolated from Channel 1 emitter. |
| 5 | Base (Channel 2) | Internally biased via same R1/R2 network as Pin 2; enables synchronous or independent dual-channel control. |
| 6 | Collector (Channel 2) | Second output node; allows dual-load switching (e.g., complementary signals or redundant outputs) in single footprint. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent PNP channels | Two fully isolated pre-biased transistors in one SOT563 package reduce PCB area by ~40% vs. discrete solutions. |
| Integrated bias network (R1=2.2kΩ, R2=47kΩ) | Eliminates four external resistors per channel, cutting BOM count and layout complexity for logic-level interface designs. |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications requiring extended temperature operation and reliability testing. |
| VL(ON) = -1.9V at IO = -5mA | Ensures robust turn-on with standard 3.3V/5V CMOS outputs, providing ≥1.1V noise margin against ground bounce. |
| VCE(SAT) ≤ -0.3V | Reduces power loss to <1.5mW at 5mA load, critical for battery-powered modules and thermally constrained enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual pre-biased PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA114EH-7 | R1 = 10kΩ, R2 = 10kΩ; lower GL = 30; VL(ON) = -3.0V | Requires higher input voltage swing; better suited for 5V-only systems with stronger drive capability | Select when interfacing with legacy 5V microcontrollers and needing tighter input threshold control. |
| DDA143EH-7 | R1 = 4.7kΩ, R2 = 4.7kΩ; higher IO = -100mA; VL(ON) = -1.9V but VL(OFF) = -0.3V | Lower input noise margin; optimized for faster switching in 3.3V systems with marginal ground stability | Prefer for high-speed digital isolation where input hysteresis is less critical than propagation delay. |
Compared with DDA114EH-7 and DDA143EH-7, DDA123JH-7 offers the optimal balance of input threshold (-1.9V), noise margin (-0.5V VL(OFF)), and bias ratio (2.2kΩ/47kΩ) for mixed-voltage automotive body-control modules requiring both 3.3V and 5V compatibility.

FAQ
What is the maximum continuous output current per channel for DDA123JH-7?
The DDA123JH-7 supports -100mA continuous output current per channel at TA = +25°C with derating to zero at +150°C ambient. This rating assumes operation within the 150mW power limit and proper PCB copper pour per Diodes' SOT563 layout guidelines.
Can DDA123JH-7 be used in 3.3V logic systems?
Yes-its VL(ON) = -1.9V and VL(OFF) = -0.5V provide sufficient margin for 3.3V CMOS outputs, delivering guaranteed turn-on with ≥1.1V noise immunity and sub-0.3V saturation voltage under 5mA load conditions.
Is thermal performance affected by PCB layout?
Yes-RθJA = 833°C/W is measured on FR4 with Diodes' recommended SOT563 pad layout (available at diodes.com/package-outlines.html). Reducing copper area or omitting thermal vias increases junction temperature by up to 40°C at full 150mW dissipation.
Does DDA123JH-7 support bidirectional signal translation?
No-it is a unidirectional PNP switch configured only for high-side sinking. The internal resistor network and emitter-collector polarity prevent reverse current flow or level-shifting from low-voltage to high-voltage domains without external circuitry.
