Product details
Overview
DDA114TH-7 from Diodes Incorporated is a PNP pre-biased dual small-signal transistor in SOT563 package, featuring integrated 10kΩ and 10kΩ bias resistors (R1 = R2 = 10kΩ), −50V VCEO, −100mA IO, −0.3V VCE(SAT) at −2.5mA/−0.25mA, and hFE = 100–600. It enables compact, reliable switching in automotive body control modules and industrial sensor interface circuits.
For engineers reviewing the DDA114TH-7 datasheet, DDA114TH-7 pinout, DDA114TH-7 application, or DDA114TH-7 equivalent, key selection criteria include verified dual-PNP topology with matched base resistors, AEC-Q101 qualification, SOT563 thermal performance (RθJA = 833°C/W), and guaranteed −50V breakdown rating under automotive ambient conditions.
Technical Context
This device integrates two identical PNP transistors with on-die 10kΩ base-emitter and base-collector resistors per channel, eliminating external bias components. Its epitaxial planar construction ensures stable hFE across −55°C to +150°C and supports fast switching up to 250MHz fT.
Designed for high-reliability automotive applications, it meets AEC-Q101 stress test requirements and operates with input voltage range of −1.1V (VL(OFF)) to −3.0V (VL(ON)) at VCC = −5V, delivering consistent −0.1V output saturation under −10mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50V - Withstands reverse collector-emitter voltage up to −50V without breakdown, enabling use in 24V automotive supply rails with margin. |
| IO (Max) | −100mA - Supports dual-channel switching loads up to 100mA per transistor, sufficient for LED drivers and relay coils. |
| VCE(SAT) | −0.3V @ −2.5mA/−0.25mA - Low saturation voltage minimizes power loss and self-heating in always-on control paths. |
| hFE | 100–600 @ −1mA, −5V - Wide DC current gain range allows robust biasing across process and temperature variation. |
| fT | 250MHz - Enables signal amplification or high-speed switching in low-power RF front-end stages or clock buffers. |
| R1 / R2 | 10kΩ / 10kΩ - Matched internal bias resistors simplify PCB layout and eliminate discrete resistor placement for each channel. |
| PD | 150mW - Power dissipation limit compatible with SOT563 footprint on FR4 boards using recommended pad layout. |
Pinout & Package
SOT563 surface-mount package: 6-pin, dual-transistor configuration with common emitter connection per channel; molded plastic case rated UL 94V-0, 0.005g weight, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (Channel A) | Common emitter node for first PNP transistor; tied directly to PCB ground plane in typical switch configurations. |
| 2 | Base (Channel A) | Input node with internal 10kΩ resistor to emitter (Pin 1) and 10kΩ resistor to collector (Pin 3). |
| 3 | Collector (Channel A) | Output node connected through internal 10kΩ resistor to base (Pin 2); sinks current when driven low at base. |
| 4 | Emitter (Channel B) | Common emitter node for second PNP transistor; electrically isolated from Pin 1 but same potential in dual-channel layout. |
| 5 | Base (Channel B) | Input node with internal 10kΩ resistor to emitter (Pin 4) and 10kΩ resistor to collector (Pin 6). |
| 6 | Collector (Channel B) | Output node connected through internal 10kΩ resistor to base (Pin 5); functionally identical to Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood operation including temperature cycling, HTRB, and ESD testing per JESD47. |
| Dual PNP with matched R1/R2 | Two independent channels share identical 10kΩ/10kΩ resistor network, reducing component count and layout mismatch risk. |
| SOT563 footprint | Compact 2.2mm × 1.35mm outline enables high-density routing in space-constrained ECUs and sensor nodes. |
| Lead-free & Green compliant | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb), fully RoHS 2 compliant for global automotive supply chains. |

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 |
|---|---|---|---|
| DDA114EH-7 | R1 = 10kΩ, R2 = 10kΩ; identical bias network but lower IO rating (−50mA vs −100mA). | Rated for lower current loads only; unsuitable for >50mA relay drivers or LED banks. | Select when load current stays below 50mA and cost sensitivity outweighs headroom needs. |
| DDA143TH-7 | R1 = 4.7kΩ, R2 = 47kΩ; asymmetric bias network optimized for higher gain at low base drive. | Better suited for microcontroller GPIOs with limited sink capability (e.g., 1mA max). | Prefer when driving from weak-output MCUs or requiring hFE > 300 at IC = −0.1mA. |
Compared with DDA114EH-7, DDA114TH-7 delivers double the output current headroom while retaining identical resistor matching; versus DDA143TH-7, it trades asymmetric bias flexibility for symmetrical channel behavior and tighter VCE(SAT) consistency across load range.

FAQ
Is DDA114TH-7 pin-compatible with DDA114EH-7?
Yes - both use identical SOT563 pinout and dual-PNP topology. However, DDA114TH-7 supports −100mA per channel versus −50mA for DDA114EH-7, so substitution requires verifying load current limits and thermal derating curves.
What is the maximum operating temperature for continuous use?
The device is rated for TJ = −55°C to +150°C. At TA = +85°C, derated power dissipation is 75mW (per Fig. 1), requiring ≤0.75mm² copper pour per channel on FR4 to maintain junction temperature within limit.
Does DDA114TH-7 support 12V automotive battery disconnect scenarios?
Yes - its −50V VCEO and −50V VCBO ratings exceed ISO 7637-2 pulse 5a (−100V/50ms) clamping requirements when used with appropriate TVS protection, making it suitable for unswitched battery rail monitoring.
Can DDA114TH-7 be used in linear amplifier mode?
No - it is characterized and qualified exclusively for switching operation. The hFE specification applies only at VCE = −5V and IC = −1mA; no linearity, THD, or small-signal parameters are specified in DS30420 Rev. 6-2.
