Product details
Overview
ADTC114YUAQ-7 from Diodes Incorporated is an AEC-Q101-qualified NPN pre-biased small-signal transistor in SOT323 package, featuring integrated 10 kΩ and 47 kΩ bias resistors, 50 V VCC, 100 mA IC(max), and 250 MHz fT, designed for automotive signal switching in body control modules and lighting drivers.
For engineers reviewing the ADTC114YUAQ-7 datasheet, ADTC114YUAQ-7 pinout, ADTC114YUAQ-7 application, or ADTC114YUAQ-7 equivalent, key selection criteria include guaranteed logic-level turn-on (VIN(ON) ≤ 1.4 V), low saturation voltage (VCE(SAT) ≤ 0.3 V at 5 mA), ±30% R1 tolerance, AEC-Q101 qualification, and SOT323 thermal resistance of 375 °C/W on FR-4.
Technical Context
This device integrates two precision bias resistors (R1 = 10 kΩ, R2 = 47 kΩ) to eliminate external base-drive components in digital switching circuits. Its epitaxial planar construction ensures stable hFE (min 68) and fast switching with 250 MHz gain-bandwidth product.
Designed for automotive environments, it operates across –55 °C to +150 °C, supports 70 mA continuous output current, and guarantees logic-compatible input thresholds: VIN(OFF) ≤ 0.3 V ensures reliable off-state, while VIN(ON) ≥ 1.4 V enables robust TTL/CMOS interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Max | 50 V - supports 12 V/24 V automotive rail operation with margin |
| IC(max) | 100 mA - sufficient for LED driver and relay coil control loads |
| VCE(SAT) | 0.1–0.3 V @ 5 mA - minimizes power loss and self-heating in switching mode |
| fT | 250 MHz - enables high-speed digital switching up to ~10 MHz square-wave operation |
| R1 / R2 | 10 kΩ / 47 kΩ - provides fixed 1:4.7 bias ratio for predictable saturation and noise immunity |
| hFE | 68 min @ 5 mA - ensures reliable current amplification without external gain-setting |
| PD | 330 mW @ TA = 25 °C - defines maximum dissipation on standard FR-4 PCB with minimal copper |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD114YUT1G | R1/R2 = 10 kΩ/47 kΩ; same SOT323; fT = 200 MHz (vs. 250 MHz); hFE min = 60 | Lower fT limits usable PWM frequency; identical AEC-Q101 qualification and thermal specs | Select when cost sensitivity outweighs marginal speed requirement |
| DTC114YKAT146 | Same R1/R2 values; SOT23 package; RθJA = 350 °C/W; PD = 350 mW; non-automotive grade | Larger footprint and no AEC-Q101 qualification; higher power rating but lower reliability assurance | Select only for non-automotive industrial controls where qualification is not required |
Compared with NSVD114YUT1G and DTC114YKAT146, ADTC114YUAQ-7 delivers superior high-frequency response (250 MHz vs. 200 MHz), guaranteed automotive qualification, and optimized thermal resistance for compact under-hood layouts-making it the preferred choice for safety-critical, space-constrained automotive switching.

FAQ
What is the maximum continuous collector current for ADTC114YUAQ-7?
The ADTC114YUAQ-7 supports a maximum continuous collector current of 100 mA, verified under absolute maximum ratings. At 70 mA output current, it maintains stable VCE(SAT) ≤ 0.3 V and thermal performance within its 330 mW power dissipation limit on standard FR-4 PCBs.
Does ADTC114YUAQ-7 require external bias resistors?
No. ADTC114YUAQ-7 integrates 10 kΩ (R1) and 47 kΩ (R2) bias resistors internally, eliminating the need for external base-drive components. This simplifies design, reduces PCB area, and improves consistency in automotive-grade switching applications.
Is ADTC114YUAQ-7 qualified for automotive use?
Yes. ADTC114YUAQ-7 is fully qualified to AEC-Q101 standards and PPAP-capable. It undergoes rigorous stress testing-including temperature cycling, humidity, and mechanical shock-to ensure reliability in under-hood automotive environments up to 150 °C junction temperature.
What is the input voltage threshold for guaranteed turn-on?
The ADTC114YUAQ-7 guarantees turn-on when input voltage exceeds 1.4 V (VIN(ON)), tested at VO = 0.3 V and IO = 1 mA. This ensures compatibility with 3.3 V and 5 V logic families while rejecting noise below 0.3 V (VIN(OFF)).
