Product details
Overview
DDTC114YCAQ-7-F from Diodes Incorporated is an NPN pre-biased small-signal transistor in SOT23 package, featuring integrated bias resistors R1 = 10 kΩ and R2 = 47 kΩ (R1 ≠ R2), VCEO = 50 V, IC(MAX) = 70 mA, and AEC-Q101 qualified for automotive applications such as LED load switching and logic-level interface circuits.
For engineers reviewing the DDTC114YCAQ-7-F datasheet, DDTC114YCAQ-7-F pinout, DDTC114YCAQ-7-F application, or DDTC114YCAQ-7-F equivalent, key selection criteria include input voltage thresholds (VI(ON) = 1.3 V @ IO = 1 mA), output saturation voltage (VCE(SAT) ≤ 0.3 V), DC current gain (hFE = 68 @ IC = 5 mA), thermal resistance (RθJA = 625 °C/W), and automotive qualification status.
Technical Context
This device integrates two discrete resistors (R1 = 10 kΩ, R2 = 47 kΩ) on-die to configure a fixed-current bias network that enables single-resistor drive operation. It operates as a digital switch with defined turn-on/turn-off thresholds and supports direct microcontroller GPIO interfacing without external base resistors.
The SOT23 package delivers 200 mW power dissipation at TA = 25°C, with guaranteed operation from −55°C to +150°C. Its VI(OFF) = 0.3 V and VI(ON) = 1.3 V ensure robust noise immunity and clean logic-level translation in 3.3 V and 5 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching. |
| IC(MAX) | 70 mA - Continuous collector current limit; suitable for driving LEDs, relays, and small solenoids. |
| R1 / R2 | 10 kΩ / 47 kΩ - Fixed internal bias network enabling resistorless logic-level drive and predictable switching thresholds. |
| VI(ON) | 1.3 V @ IO = 1 mA - Input voltage required to saturate transistor; compatible with 3.3 V CMOS outputs. |
| VCE(SAT) | ≤ 0.3 V @ IC/IB = 5 mA/0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| hFE | 68 @ VCE = 5 V, IC = 5 mA - Confirmed DC current gain ensures stable switching margin under temperature variation. |
| fT | 250 MHz - Gain-bandwidth product confirms suitability for low-speed digital switching (not RF). |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin-plated leads, moisture sensitivity level 1, UL 94V-0 rated, weight ≈ 0.008 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected internally to R2; provides common reference for bias network and output return path. |
| 2 (Base) | Input control node | Internal connection point between R1 and R2; accepts logic-level input to enable transistor conduction. |
| 3 (Collector) | Switched output terminal | High-side connection for load; carries full switched current with minimal VCE(SAT) drop. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 ≠ R2 bias network | Eliminates need for external base resistors and ensures consistent turn-on behavior across temperature and process variation. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test requirements. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) compliant with environmental regulations. |
| SOT23 footprint compatibility | Standardized 3-pin layout enables drop-in replacement in existing PCB designs using industry-standard reflow profiles. |

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 |
|---|---|---|---|
| DDTC114YCA-7-F | Same die and electrical specs, but standard (non-automotive) qualification; no PPAP documentation support. | Lacks AEC-Q101 certification and automotive traceability; unsuitable for production vehicles. | Select when cost-sensitive industrial or consumer use cases do not require automotive compliance. |
| NSV114YMT1G | Onsemi part with identical R1/R2 values (10 kΩ/47 kΩ), same SOT23 package, but VCEO = 40 V and IC(MAX) = 60 mA. | Lower voltage/current ratings limit use in 24 V systems with transient spikes or higher-load indicators. | Acceptable for 12 V-only applications where margin below 50 V is acceptable and lower gain (hFE = 56) is tolerable. |
Compared with DDTC114YCAQ-7-F, DDTC114YCA-7-F offers identical performance without automotive validation, while NSV114YMT1G trades 10 V/10 mA headroom for alternate supply chain availability-critical for dual-sourcing strategies in long-lifecycle automotive programs.

FAQ
What is the maximum operating temperature for DDTC114YCAQ-7-F?
The device is rated for junction and storage temperatures from −55°C to +150°C. Its thermal resistance RθJA = 625 °C/W means that at 70 mA collector current and 0.3 V saturation voltage, power dissipation remains ~21 mW-well within the 200 mW limit at room ambient, allowing safe operation up to +125°C case temperature in typical PCB layouts.
Does DDTC114YCAQ-7-F require an external base resistor?
No. The device integrates R1 = 10 kΩ and R2 = 47 kΩ internally, forming a complete bias network. This eliminates the need for any external base resistor and ensures repeatable switching behavior independent of PCB layout parasitics or manufacturing variation.
How does the "Q" suffix in DDTC114YCAQ-7-F affect its specifications?
The "Q" denotes automotive qualification per AEC-Q101 standards and PPAP capability. Electrically and thermally, it is identical to the non-Q version (DDTC114YCA-7-F); the difference lies solely in enhanced test coverage, lot traceability, and documentation required for automotive production release.
Can DDTC114YCAQ-7-F be used in 3.3 V logic systems?
Yes. With VI(ON) = 1.3 V (typical) at IO = 1 mA and VI(OFF) = 0.3 V, it provides >1 V noise margin against 3.3 V CMOS logic levels. Its input threshold is fully compatible with standard 3.3 V GPIO outputs without level shifting or additional circuitry.
