Product details
Overview
DDA114TU-7 from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 10kΩ input bias resistor (R1), −50V VCEO, −100mA IO, and −0.3V VCE(sat) at IC/IB = −10mA/−1mA. It serves as a compact, logic-compatible switching element in low-voltage digital interface circuits, such as microcontroller GPIO load drivers and LED sink arrays.
For engineers reviewing the DDA114TU-7 datasheet, DDA114TU-7 pinout, DDA114TU-7 application, or DDA114TU-7 equivalent, this device is selected for its guaranteed hFE of 100–250, tight R1 tolerance (±30%), and AEC-Q101-qualified variants - critical when designing reliable discrete logic-level translators and level-shifted signal conditioning stages.
Technical Context
This dual PNP transistor integrates two identical pre-biased elements sharing common emitter connections per channel, with each channel containing a single 10kΩ base-input resistor (R1) and no R2 - confirmed by ordering table and schematic labeling. Its operation is optimized for DC switching at VCC ≤ −50V and IO up to −100mA per channel, with guaranteed saturation under IC/IB = −10mA/−1mA.
The device uses epitaxial planar die construction and is rated for −55°C to +150°C operation. Thermal resistance is 625°C/W (J-A), and power dissipation is limited to 200mW total (150mW per element), requiring FR-4 PCB layout with minimum pad area per Diodes' recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50V - supports rail-to-rail switching in −5V to −48V industrial bus interfaces |
| IO (max) | −100mA - drives medium-current loads like relay coils or multi-LED strings without external driver stage |
| VCE(sat) | −0.3V @ IC/IB = −10mA/−1mA - ensures <0.3mW dissipation per switch at 10mA, minimizing self-heating |
| hFE | 100–250 @ IC = −1mA, VCE = −5V - provides predictable current gain across production lots for stable bias design |
| R1 | 10kΩ ±30% - sets defined base current for logic-level input compatibility (e.g., 3.3V/5V MCU outputs) |
| PD | 200mW total - constrains simultaneous dual-channel conduction to ≤100mA each at ambient ≤+70°C |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, lead-free, green molding compound (UL 94V-0), 0.006g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base of Q1 | Input node for first PNP transistor; connected internally to 10kΩ R1 resistor |
| 2 | Emitter of Q1 | Common emitter terminal for Q1; tied to system ground or negative rail in sink configuration |
| 3 | Collector of Q1 | Output node for Q1; connects to load anode (e.g., LED cathode or relay coil) |
| 4 | Collector of Q2 | Output node for second PNP transistor; electrically isolated from Q1 collector |
| 5 | Emitter of Q2 | Common emitter terminal for Q2; internally tied to Pin 2 (shared emitter) |
| 6 | Base of Q2 | Input node for Q2; connected internally to identical 10kΩ R1 resistor |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistor | Single 10kΩ R1 per channel eliminates external base resistors, reducing BOM count and PCB area |
| Guaranteed hFE range | 100–250 ensures consistent switching thresholds across temperature and voltage, simplifying drive logic design |
| SOT363 footprint | Standard 6-pin package enables drop-in replacement for other DDA/DDC series and compatible dual transistors |
| AEC-Q101 qualification path | Q-qualified variants (e.g., DDA114TUQ) support automotive body electronics where change control and PPAP are mandatory |
Applications
| Microcontroller GPIO Expansion | Industrial LED Status Indication |
|---|---|
Use Scenario: Driving multiple high-side loads from limited GPIO pins on ARM Cortex-M or PIC microcontrollers. IC Role / Device Role / Timing Role: Dual PNP switch providing independent, resistor-biased sinking capability for up to two 100mA loads. Use Value: Eliminates need for discrete base resistors and reduces routing congestion on dense MCU boards while maintaining <0.3V saturation for minimal voltage drop. |
Use Scenario: Controlling multi-color status LEDs in PLC I/O modules operating from −24V rails. IC Role / Device Role / Timing Role: Dual-channel sink driver interfacing between isolated logic and common-anode LED arrays. Use Value: −50V VCEO rating allows direct connection to −24V supply without level-shifting; shared-emitter topology simplifies return path layout. |

Use Scenario: Clamping and translating logic signals in legacy serial communication lines exposed to ESD or voltage transients. IC Role / Device Role / Timing Role: Fast-switching PNP clamp protecting UART TX/RX lines from overvoltage during hot-plug events. Use Value: −0.3V VCE(sat) ensures low forward voltage during clamping, preserving signal integrity below −0.5V threshold of downstream receivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased PNP dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA114YU-7-F | R1 = 10kΩ, R2 = 47kΩ - includes second bias resistor for enhanced noise immunity and sharper turn-off | Preferred in noisy environments (e.g., motor drive feedback paths) where fast cutoff is required | Select when VIN(off) > −0.3V is needed to prevent false triggering; adds 0.5mm² PCB area |
| DDA124EU-7-F | R1 = R2 = 22kΩ - symmetrical dual-resistor network yields higher input impedance and lower base current | Better suited for high-impedance logic sources (e.g., open-drain I²C buffers) needing reduced loading | Choose when driving from weak-sourcing nodes; sacrifices 10% saturation speed vs. DDA114TU |
Compared with DDA114YU-7-F and DDA124EU-7-F, DDA114TU-7 offers the lowest input resistance (10kΩ only), enabling fastest turn-on response and highest drive strength from standard CMOS outputs - ideal for time-critical GPIO expansion where simplicity and speed outweigh noise margin needs.

FAQ
What is the maximum continuous current per channel for DDA114TU-7?
The absolute maximum output current per channel is −100mA, verified under conditions of VCE ≤ −5V and TA ≤ +25°C. Derating applies above +25°C ambient: power dissipation must remain ≤150mW per element, limiting usable current to ~−70mA at +70°C with standard FR-4 layout.
Does DDA114TU-7 have a built-in pull-down resistor on the base?
No - DDA114TU-7 contains only one internal 10kΩ resistor (R1) connected between base and input pin; there is no R2 or emitter-connected resistor. This configuration provides fixed base current for turn-on but requires external pull-down or logic-controlled low-state to ensure full cutoff.
Can DDA114TU-7 be used in automotive applications?
Yes - the qualified variant DDA114TUQ-7-F is AEC-Q101 certified, PPAP-capable, and manufactured in IATF 16949-certified facilities. The standard DDA114TU-7-F is not qualified but shares identical die and package; it may be used in non-safety-critical automotive subsystems pending internal validation.
What is the typical VCE(sat) at IC = −50mA?
Per Figure 3 in DS30346 Rev. 14-2, VCE(sat) is approximately −0.35V at IC = −50mA and TA = +25°C, with IB = −5mA (IC/IB = 10). At −50mA, power dissipation per channel reaches 17.5mW, well within the 150mW per-element limit.
