Product details
Overview
DDTC114ELP-7 from Diodes Incorporated is a 50V NPN pre-biased small-signal transistor in DFN1006 package with integrated 10kΩ base resistors (R1 = R2), designed for digital switching and level translation in space-constrained PCBs. It delivers 100mA max collector current, 250mW power dissipation, 250MHz fT, and AEC-Q101 qualification for automotive signal conditioning.
For engineers reviewing the DDTC114ELP-7 datasheet, DDTC114ELP-7 pinout, DDTC114ELP-7 application, or DDTC114ELP-7 equivalent, key selection criteria include input threshold voltage (VI(on) = 2.5V typ), output saturation voltage (VCE(sat) ≤ 0.25V at 50mA), resistor-matched biasing, thermal resistance (RθJA = 500°C/W), and leadless DFN1006 footprint compatibility.
Technical Context
This device integrates two matched 10kΩ resistors to form a single-input inverter circuit: base driven through R1, emitter tied to ground via R2, enabling direct TTL/CMOS logic-level interfacing without external bias components. Its epitaxial planar die construction ensures stable hFE across temperature (−55°C to +150°C).
The X1-DFN1006-3 package features an exposed collector pad for thermal conduction, NiPdAu terminal finish for solderability, and J-STD-020 Level 1 moisture sensitivity-optimized for high-speed automated placement and reflow in automotive and industrial control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50V - Supports rail-to-rail switching up to 50V supply without breakdown in common-emitter configuration. |
| IC(MAX) | 100mA - Enables driving moderate-current loads such as LED indicators, relay coils, or gate inputs of power MOSFETs. |
| VCE(sat) | ≤0.25V @ 50mA/5mA - Minimizes conduction loss and self-heating during saturated switching in low-voltage logic interfaces. |
| fT | 250MHz - Sufficient bandwidth for high-speed digital signal inversion up to ~100MHz edge rates in timing-critical paths. |
| R1/R2 | 10kΩ ±30% - Matched internal bias network eliminates discrete resistor layout, reduces BOM count, and improves production yield. |
| PD | 250mW - Allows continuous operation at ambient temperatures up to +85°C when mounted on minimum recommended copper pad layout. |
Pinout & Package
Package: X1-DFN1006-3 (1.0 × 0.6 mm, 0.5 mm height), ultra-small leadless surface-mount package with exposed collector pad for thermal management and NiPdAu-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input node connected to R1 | Accepts logic-level input (0.5–2.5V threshold); ties directly to MCU GPIO or logic gate output. |
| 2 (GND) | Emiter reference / R2 return | Common ground connection for bias network and load return path; electrically isolated from substrate. |
| 3 (OUT) | Collector output node | Switched output terminal; connects to load (e.g., LED anode, MOSFET gate); exposed pad is collector potential. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8kV), enabling use in engine control and body electronics. |
| Matched R1/R2 ratio | 0.8–1.2 ratio tolerance ensures consistent VI(off)/VI(on) thresholds across production lots, reducing calibration overhead in mass production. |
| Lead-free & halogen-free | Meets RoHS 2 (2011/65/EU) and JEDEC JS709C green standards (<900ppm Br, <900ppm Cl, <1000ppm Sb), supporting eco-compliant manufacturing. |
| J-STD-020 Level 1 | No floor life limitation before reflow; compatible with standard SMT assembly lines without dry pack or baking requirements. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD114ELT1G | Same DFN1006 package, but R1 = 10kΩ, R2 = open (single-resistor topology); hFE min = 30 vs. 10–100 range. | Lacks emitter feedback resistor → higher input current required; less stable VI(on) over temperature. | Prefer when only base bias needed and lower cost is critical; avoid where precise threshold control is required. |
| DTC114EKT146 | SOT-23-3 package (3.0 × 1.4 mm); identical R1/R2 = 10kΩ, same electrical specs, but 5× larger footprint and higher RθJA (625°C/W). | Not suitable for ultra-dense layouts; requires more PCB area and has reduced thermal performance. | Select only if legacy SOT-23 tooling exists or DFN assembly capability is unavailable. |
Compared with NSVD114ELT1G and DTC114EKT146, DDTC114ELP-7 uniquely combines matched dual-resistor biasing, AEC-Q101 qualification, and minimal 1.0 × 0.6 mm footprint-making it optimal for next-generation automotive and portable electronics where size, reliability, and threshold consistency are jointly constrained.

FAQ
What is the maximum operating junction temperature for DDTC114ELP-7?
The device supports continuous operation from −55°C to +150°C junction temperature. At ambient +85°C with 250mW dissipation and RθJA = 500°C/W, calculated TJ = 210°C-exceeding rating-so derating to ≤125mW is required above +25°C per the 2mW/°C derating curve shown in Figure 1.
Can DDTC114ELP-7 be used as a high-side switch?
No. The internal schematic shows emitter tied to GND via R2, and collector is the output terminal; this defines a low-side switching configuration only. Using it as a high-side switch would reverse bias the internal R2 and violate absolute maximum ratings for VEB(OFF).
Is the exposed pad electrically connected, and how should it be handled in layout?
Yes-the exposed pad is internally connected to the collector. It must be soldered to a dedicated copper pour tied to the collector net for thermal and electrical integrity. Per AP02001, the recommended pad is 0.7 × 0.7 mm with thermal vias to inner ground/power planes.
Does DDTC114ELP-7 support 1.8V logic input levels?
No. VI(on) is specified at 2.5V typical (min 1.16V), and VI(off) max is 0.5V. A 1.8V logic HIGH falls within the undefined transition region (0.5–2.5V), risking partial turn-on and excessive power dissipation; it is not guaranteed to operate reliably below 2.5V input.
