Product details
Overview
DDTC114WE-7 from Diodes Incorporated is an NPN pre-biased transistor in SOT523 package, featuring integrated R1 = 10 kΩ and R2 = 4.7 kΩ bias resistors (R1 ≠ R2), VI(OFF) = 0.8 V, VI(ON) = 1.3 V at IO = 2 mA, and DC current gain GI = 24 at VO = 5 V / IO = 5 mA. It serves as a compact, logic-compatible switch in low-power digital interface circuits.
For engineers reviewing the DDTC114WE-7 datasheet, DDTC114WE-7 pinout, DDTC114WE-7 application, or DDTC114WE-7 equivalent, key selection criteria include input threshold voltage compatibility with 1.8–3.3 V logic families, guaranteed turn-on/off behavior under pulsed load conditions, thermal derating in space-constrained PCB layouts, and RoHS-compliant "Green" packaging for automotive and industrial control modules.
Technical Context
This device integrates an NPN bipolar transistor with two non-matching on-chip base bias resistors (R1 = 10 kΩ, R2 = 4.7 kΩ), enabling predictable switching without external components. Its VI(OFF) = 0.8 V ensures reliable cutoff with sub-1 V logic high noise margins, while VI(ON) = 1.3 V supports direct drive from 1.8 V CMOS outputs.
The 150 mW power dissipation rating and 833 °C/W junction-to-ambient thermal resistance are validated on FR-4 with minimum pad layout. With fT = 250 MHz and IC(max) = 100 mA, it operates in linear and saturated switching modes up to ~10 MHz signal edges in level-shifting and LED-driving applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VI(OFF) | 0.8 V - Ensures full cutoff when driven by 1.8 V logic with ≥1.0 V noise margin |
| VI(ON) | 1.3 V @ IO = 2 mA - Guarantees saturation with 1.8 V or 3.3 V GPIO outputs |
| GI (hFE) | 24 @ VO = 5 V, IO = 5 mA - Provides stable current amplification for low-IOUT loads (≤100 mA) |
| PD | 150 mW - Limits continuous operation to ≤100 mA at ambient ≤85°C with standard pad layout |
| RθJA | 833 °C/W - Requires thermal-aware placement near board edges or copper pour for >50 mA duty cycles |
| fT | 250 MHz - Supports fast edge response in pulse-width modulated (PWM) LED dimming up to 10 MHz |
Pinout & Package
Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.75 mm), matte tin-plated leads, moisture sensitivity level 1, weight ≈ 0.002 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Input reference node for R2 resistor | Connected internally to R2 (4.7 kΩ); provides ground-referenced bias path for logic-level input |
| 2 (Base) | Internal transistor base connection | Not externally accessible; tied between R1 and R2 to set fixed bias point for predictable VBE |
| 3 (Collector) | Output current sink terminal | Drives loads (e.g., LED anode, MCU input pull-down) with max 100 mA continuous, 0.3 V saturation |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | R1 = 10 kΩ, R2 = 4.7 kΩ (±30% R1 tolerance, ±20% R2/R1 ratio) - eliminates 2 external resistors and layout uncertainty |
| Logic-compatible input thresholds | VI(OFF) = 0.8 V, VI(ON) = 1.3 V - enables direct interface with 1.8 V and 3.3 V microcontrollers without level shifters |
| Low-power switching capability | IOUT = 100 mA max, PD = 150 mW - suitable for driving LEDs, small relays, and logic inputs in battery-powered devices |
| Automotive-qualified process option | AEC-Q101 qualified variants available - supports functional safety-critical sensing and actuation in IATF 16949 production environments |
Applications
| LED Indicator Control | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Driving discrete status LEDs from low-current MCU pins in portable medical monitors. IC Role / Device Role / Timing Role: Logic-level NPN switch sinking LED cathode current (5–20 mA). Use Value: Eliminates need for discrete base resistors; VI(ON) = 1.3 V ensures full turn-on from 1.8 V ARM Cortex-M0+ GPIOs. |
Use Scenario: Adding active-low reset or interrupt inputs to resource-constrained IoT sensor nodes. IC Role / Device Role / Timing Role: Level-translating open-drain signal conditioner for 3.3 V MCU inputs receiving 5 V peripheral alerts. Use Value: R1/R2 network guarantees clean logic transitions without external pull-ups or clamping diodes. |
| Low-Voltage Sensor Interface | Power Sequencing Control |
|
Use Scenario: Enabling/disabling analog sensor supply rails (e.g., 2.5 V LDO output) based on system sleep state. IC Role / Device Role / Timing Role: Low-leakage enable switch controlling PMOS gate drive in power management subsystems. Use Value: IO(OFF) = 0.5 μA at VCC = 50 V minimizes standby current; VI(OFF) = 0.8 V prevents false wake-up from noise. |
Use Scenario: Controlling sequencing of multiple DC/DC converters in FPGA carrier boards with strict power-up order. IC Role / Device Role / Timing Role: Delayed-enable buffer triggered by upstream regulator PG signal. Use Value: Fixed R1/R2 bias ensures consistent propagation delay (<100 ns) across temperature and voltage, unlike RC-based solutions. |
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 |
|---|---|---|---|
| DDTC114YE-7-F | R1 = 10 kΩ, R2 = 47 kΩ → higher VI(ON) = 1.3 V but lower II = 0.88 mA at VI = 5 V | Better suited for high-impedance 3.3 V logic sources where input loading must be minimized | Select when driving from weak-sourcing MCU pins or battery-sensitive systems requiring <1 μA static input current |
| DDTC124XE-7-F | R1 = 22 kΩ, R2 = 47 kΩ → VI(ON) = 1.4 V, GI = 68, II = 0.36 mA at VI = 5 V | Higher DC gain and lower input current support longer trace routing and higher capacitive loads | Prefer for noisy industrial environments or long-flex PCB traces where robust noise immunity and gain stability are critical |
Compared with DDTC114YE-7-F and DDTC124XE-7-F, DDTC114WE-7 offers balanced input sensitivity (1.3 V threshold) and moderate gain (GI = 24), making it optimal for general-purpose 1.8–3.3 V logic interfacing where both speed and low static power matter.

FAQ
What is the maximum continuous collector current for DDTC114WE-7?
The absolute maximum rated collector current is 100 mA, verified per DS30314 Rev.10-2. Derating begins above +25°C ambient: at +85°C, maximum continuous IC drops to ~60 mA due to 150 mW power limit and 833 °C/W thermal resistance on standard FR-4 pads.
Can DDTC114WE-7 replace a standard 2N3904 with external bias resistors?
Yes, but only in saturated-switch applications-not linear amplification. Its internal R1/R2 network fixes base bias, eliminating resistor selection effort and layout variability. Unlike 2N3904, it guarantees VI(ON) = 1.3 V and VI(OFF) = 0.8 V, enabling deterministic logic-level interfacing without iterative tuning.
Is DDTC114WE-7 qualified for automotive use?
The base DDTC114WE-7 is not AEC-Q101 qualified, but Diodes offers automotive-grade variants (e.g., DDTC114WE-7-F with PPAP documentation and IATF 16949 manufacturing). These meet AEC-Q101 stress testing and require explicit ordering with automotive suffixes and change control protocols.
What is the meaning of the marking code 'N15' on the device top?
'N15' is the Diodes Incorporated date and product code: 'N' indicates year 2025, '15' denotes week 15 (early April). This matches the 'YM XX' format defined in DS30314 - no additional lot or revision data is encoded in this marking; full traceability requires reel label or shipping documentation.
