Product details
Overview
DDC114YUQ-7-F from Diodes Incorporated is an NPN pre-biased dual small-signal transistor in SOT363 package, featuring integrated 10 kΩ and 47 kΩ bias resistors (R1/R2), 70 mA output current capability, 50 V collector-emitter breakdown voltage, and AEC-Q101 qualification for automotive use in level-shifting and digital logic interface circuits.
For engineers reviewing the DDC114YUQ-7-F datasheet, DDC114YUQ-7-F pinout, DDC114YUQ-7-F application, or DDC114YUQ-7-F equivalent, this part supports high-reliability automotive signal conditioning where built-in resistor matching, low saturation voltage (≤0.3 V at 5 mA), and thermal stability across –55°C to +150°C are critical selection criteria.
Technical Context
This dual NPN transistor integrates two independent pre-biased elements sharing a common emitter configuration per channel, with R1–R2 resistor network enabling direct TTL/CMOS-compatible switching without external bias components. Each channel operates with guaranteed DC current gain (GI) of 68 min at VO = 5 V, IO = 10 mA.
The device uses epitaxial planar die construction on FR-4 PCBs, delivering 200 mW total power dissipation (150 mW per element max), 625°C/W junction-to-ambient thermal resistance, and 1.1 V typical VI(on) threshold under 5 mA load - optimized for low-power digital input buffering and LED driver stages.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC114YUQ | Same R1/R2 values (10k/47k), identical SOT363 package, but active status vs. NRND for DDC114YUQ-7-F | Direct replacement with updated lifecycle status; same electrical specs and footprint | Select ADC114YUQ for new designs requiring long-term supply assurance and active product support |
| DDC114YU-7-F | Identical electrical specs and pinout, but lacks Q suffix indicating AEC-Q101 qualification and PPAP capability | Not approved for automotive applications requiring change control or IATF 16949 traceability | Use only in non-automotive industrial or consumer systems where AEC-Q101 is not mandated |
Compared with DDC114YUQ-7-F, ADC114YUQ offers identical performance with active production status and full automotive qualification continuity, while DDC114YU-7-F provides cost parity but omits AEC-Q101 validation - making it suitable only for non-automotive use cases.

FAQ
Is DDC114YUQ-7-F pin-compatible with DDC114YU-7-F?
Yes, both share identical SOT363 pinout (C1/B1/E1/E2/B2/C2), same R1/R2 resistor values (10 kΩ/47 kΩ), and identical electrical specifications. The only difference is qualification status: DDC114YUQ-7-F is AEC-Q101 qualified and PPAP-capable, while DDC114YU-7-F is not certified for automotive use.
What is the maximum continuous output current per channel?
The datasheet specifies 70 mA maximum output current (IO) for DDC114YUQ-7-F at TA = +25°C. Derating applies above 25°C: power dissipation must remain ≤150 mW per element, limiting usable current to ~50 mA at 85°C ambient when mounted on FR-4 with minimum pad layout.
Can DDC114YUQ-7-F replace discrete BJT + two resistors?
Yes - it replaces one NPN transistor plus two bias resistors per channel, reducing component count by three per switch function. Its integrated 10 kΩ/47 kΩ network delivers consistent VI(on)/VI(off) thresholds and eliminates resistor tolerance stacking, improving batch-to-batch consistency in production.
Why is DDC114YUQ-7-F marked NRND?
NRND ("Not Recommended for New Design") indicates Diodes Incorporated has superseded DDC114YUQ-7-F with ADC114YUQ, which maintains identical electrical and mechanical specifications but carries active production status and updated quality documentation. Existing designs may continue using DDC114YUQ-7-F, but new designs should adopt ADC114YUQ.
