Diodes Incorporated DDA114TUQ-13-F

Overview

DDA114TUQ-13-F from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 10 kΩ input resistor (R1) and AEC-Q101 qualification for automotive use. It delivers −100 mA output current capability, −50 V collector-emitter breakdown voltage, and −0.3 V saturation voltage at IC/IB = −10 mA / −1 mA - enabling compact, reliable high-side switching in space-constrained control circuits.

For engineers reviewing the DDA114TUQ-13-F datasheet, DDA114TUQ-13-F pinout, DDA114TUQ-13-F application, or DDA114TUQ-13-F equivalent, this part supports automotive body electronics, LED load control, and logic-level interface translation where built-in biasing eliminates external resistors and reduces PCB footprint.

Technical Context

This device integrates two identical PNP bipolar transistors with monolithically embedded R1 = 10 kΩ bias resistors connected between base and input terminal. Each channel operates as a digitally controlled switch with defined turn-on threshold (V_IN(ON) = −1.4 V @ I_O = −10 mA) and guaranteed saturation under specified drive conditions.

The SOT363 package supports dual-channel operation in 2.15 mm × 2.10 mm footprint with 0.65 mm lead pitch, and thermal resistance of 625 °C/W enables operation up to +150 °C junction temperature when mounted per recommended pad layout on FR-4 board.

FAQ

What is the maximum operating temperature for DDA114TUQ-13-F?

The device supports junction temperatures from −55 °C to +150 °C. Its 625 °C/W thermal resistance requires adherence to the recommended SOT363 pad layout on FR-4 to maintain safe operation at full 200 mW power dissipation. Derating begins above +25 °C ambient per Figure 1 in DS30346 Rev. 14-2.

Does DDA114TUQ-13-F require external base resistors?

No. It integrates a 10 kΩ resistor (R1) between the input terminal and base of each PNP transistor, eliminating the need for external biasing components. This simplifies schematic design, improves production yield, and ensures consistent turn-on characteristics across temperature and process variation.

How does the AEC-Q101 qualification impact design validation?

AEC-Q101 qualification confirms that DDA114TUQ-13-F has passed stress tests including HTOL, temperature cycling, and ESD - validating its suitability for automotive under-hood and cabin applications. It also implies PPAP documentation readiness and manufacturing in IATF 16949-certified facilities, reducing qualification effort for Tier 1 suppliers.

Can DDA114TUQ-13-F be used in 5 V logic systems?

Yes. With V_IN(ON) = −1.4 V at I_O = −10 mA and V_IN(OFF) = −0.5 V, it reliably switches using standard 5 V CMOS or TTL outputs referenced to system ground. The negative input threshold aligns with PNP high-side architecture, ensuring clean logic-to-load translation without level-shifting circuitry.
