Product details
Overview
DDA114TU-7-F from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 10kΩ input bias resistor (R1) and complementary emitter-coupled configuration for digital switching. It delivers −100mA output current, −50V collector-emitter breakdown voltage, and −0.3V saturation voltage at IC/IB = −10mA/−1mA. Used in level-shifting logic interfaces and discrete load control in automotive body electronics.
For engineers reviewing the DDA114TU-7-F datasheet, DDA114TU-7-F pinout, DDA114TU-7-F application, or DDA114TU-7-F equivalent, this page provides verified electrical parameters, validated SOT363 terminal mapping, real-world use cases in automotive signal conditioning, and confirmed alternative parts with documented R1/R2 tolerance and gain differences.
Technical Context
This device integrates two matched PNP transistors with monolithic biasing resistors-R1 = 10kΩ (±30%) on each channel-enabling direct TTL/CMOS-compatible input drive without external base resistors. Its dual-channel topology supports independent or paralleled switching paths within a single 6-pin SOT363 footprint.
Designed for operation across −55°C to +150°C, it meets AEC-Q101 requirements when ordered as DDA114TUQ variants. The −50V VCEO, −0.3V VCE(sat), and 100–250 hFE range support robust digital interface buffering in 12V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum allowable collector-emitter voltage before breakdown; enables safe operation in 24V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current per channel; sufficient to drive LEDs, small relays, or logic inputs directly. |
| VCE(sat) | −0.3 V @ IC/IB = −10mA/−1mA: Low saturation voltage minimizes power loss and self-heating during switching. |
| hFE | 100–250 @ IC = −1mA, VCE = −5V: DC current gain range ensures predictable turn-on behavior with standard logic-level inputs. |
| R1 | 10 kΩ ±30%: Integrated base bias resistor eliminates need for external components in high-side switch configurations. |
| PD | 200 mW: Total package power dissipation limit; requires thermal pad layout per Diodes' SOT363 recommendation for full rating. |
| TJ | −55°C to +150°C: Extended junction temperature range supports under-hood and engine-control module deployment. |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, lead-free, halogen-free molded plastic housing (UL 94V-0), 0.006g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of Transistor 1 | Common emitter node for first PNP channel; connects to system ground or low-side return path. |
| 2 | Base of Transistor 1 | Input node tied internally to R1 (10kΩ); accepts logic-high (≤−1.4V) to activate channel 1. |
| 3 | Collector of Transistor 1 | Output node for channel 1; sinks current from load connected to positive rail. |
| 4 | Collector of Transistor 2 | Output node for channel 2; electrically isolated from channel 1 collector but shares package thermal path. |
| 5 | Base of Transistor 2 | Input node tied internally to R1 (10kΩ); identical biasing to pin 2 for synchronous dual control. |
| 6 | Emitter of Transistor 2 | Common emitter node for second PNP channel; may be tied to pin 1 for shared emitter or left separate. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 10kΩ ±30% per channel eliminates external base resistors and reduces PCB component count by two per switch. |
| Dual PNP topology | Two independent, matched PNP transistors in one SOT363 package enable compact dual-load control without cross-talk. |
| AEC-Q101 qualified variant | DDA114TUQ-7-F version supports automotive applications with PPAP documentation and IATF 16949 manufacturing traceability. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900ppm Br, <900ppm Cl, <1000ppm Sb) meets global environmental compliance mandates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA114YU-7-F | R1 = 10kΩ, R2 = 47kΩ (vs. DDA114TU's R1-only 10kΩ); higher input impedance, lower drive strength. | Better suited for high-impedance CMOS inputs where reduced base current is critical. | Select when interfacing with ultra-low-power MCUs or battery-operated sensors requiring <−0.18mA input current. |
| DDA123JU-7-F | R1 = 2.2kΩ (vs. 10kΩ); lower input resistance yields higher base current and faster switching at cost of increased power draw. | Preferred in high-speed digital isolation where tON/tOFF < 100ns is required. | Choose when driving capacitive loads >100pF or when minimizing propagation delay outweighs quiescent current concerns. |
Compared with DDA114YU-7-F and DDA123JU-7-F, DDA114TU-7-F offers balanced input sensitivity and output drive-ideal for general-purpose automotive and industrial switching where 10kΩ biasing matches standard logic thresholds and −100mA load capability covers most solenoid/LED applications.

FAQ
What is the maximum continuous current per channel for DDA114TU-7-F?
The absolute maximum output current per channel is −100mA, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB thermal management per Diodes' recommended SOT363 pad layout; exceeding this current risks thermal runaway or permanent degradation of hFE and VCE(sat).
Does DDA114TU-7-F include a pull-down resistor on the base?
No. DDA114TU-7-F integrates only a 10kΩ pull-up resistor (R1) from base to emitter on each channel-standard for PNP pre-biased transistors. It does not contain a separate R2 resistor; that configuration appears in other variants like DDA114YU-7-F (R1=10kΩ, R2=47kΩ).
Can DDA114TU-7-F be used in place of a standard 2N3906 pair?
Yes-but only if the circuit relies on active-low logic drive and does not require independent base control. Unlike discrete 2N3906 transistors, DDA114TU-7-F fixes the base bias network internally; replacing it requires verifying that the 10kΩ R1 value matches the original design's base current requirement and that the shared emitter configuration aligns with the schematic topology.
Is the SOT363 package of DDA114TU-7-F compatible with reflow soldering per J-STD-020?
Yes. The device is rated for Moisture Sensitivity Level 1 per J-STD-020 and features matte tin-plated leads compliant with MIL-STD-202, Method 208. Standard Pb-free reflow profiles (peak 260°C, <60 sec above 217°C) are supported when using Diodes' recommended SOT363 pad dimensions and thermal relief patterns.
