Product details
Overview
DDC114EH-7 from Diodes Incorporated is an NPN pre-biased dual small-signal transistor in SOT-563 package, featuring integrated 10 kΩ input and 10 kΩ output biasing resistors. It supports 50 V VCEO, delivers 50 mA output current, exhibits VCE(sat) ≤ 0.3 V at IC/IB = 10 mA/0.5 mA, and operates across –55°C to +150°C for use in compact logic-level switching circuits.
For engineers reviewing the DDC114EH-7 datasheet, DDC114EH-7 pinout, DDC114EH-7 application, or DDC114EH-7 equivalent, key selection criteria include verified input threshold (VIN(on) = 3.0 V @ IO = 10 mA), guaranteed DC current gain (GI = 30 at VO = 5 V), and thermal resistance (RθJA = 833°C/W) on FR4 board with recommended pad layout.
Technical Context
This dual NPN transistor integrates two identical pre-biased elements sharing common emitter connections, each with R1 = 10 kΩ and R2 = 10 kΩ on-chip bias resistors. It enables direct TTL/CMOS interface without external base resistors and maintains stable switching performance up to 150°C junction temperature.
The device uses epitaxial planar die construction for consistent hFE distribution and low leakage (ICBO ≤ 0.5 µA). Its SOT-563 footprint supports high-density PCB layouts while meeting J-STD-020 Level 1 moisture sensitivity and RoHS/"Green" compliance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; ensures safe operation in 24 V and 36 V industrial control rails. |
| IO | 50 mA - Continuous output current per channel; sufficient for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | ≤ 0.3 V @ IC/IB = 10 mA/0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| GI | 30 - Input current gain (IO/IIN) at VO = 5 V; defines required drive strength for clean digital interface. |
| RθJA | 833°C/W - Thermal resistance on FR4 board; determines maximum power dissipation (150 mW) under ambient conditions. |
| VIN(on) | 3.0 V @ IO = 10 mA - Validated turn-on threshold compatible with 3.3 V logic families. |
| PD | 150 mW - Absolute maximum power dissipation; sets upper limit for continuous conduction in SOT-563 package. |
Pinout & Package
Package: SOT-563 - 6-pin ultra-small surface-mount package with 0.6 mm pitch, 1.6 mm × 1.2 mm footprint, and 0.2 mm nominal height; UL 94V-0 rated molded plastic body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input Resistor (R1) Terminal | Connects to external control signal; internal 10 kΩ resistor pulls base toward VIN. |
| 2 | Emitter (Common) | Shared emitter node for both transistors; must be tied to GND or reference potential. |
| 3 | Collector (Channel A) | Output node for first NPN element; sinks up to 50 mA when driven. |
| 4 | Collector (Channel B) | Output node for second NPN element; electrically isolated but thermally coupled to Channel A. |
| 5 | Base (Internal Junction) | Internally connected between R1 and R2; not accessible externally. |
| 6 | Input Resistor (R2) Terminal | Terminates internal 10 kΩ pull-down resistor; connects to GND for active-low configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched R1 = R2 = 10 kΩ per channel eliminates need for external base resistors in digital switching designs. |
| Dual-channel symmetry | Identical electrical characteristics across both NPN elements enable balanced load sharing in dual-output applications. |
| High-temperature operation | Rated for TJ = –55°C to +150°C; supports deployment in automotive engine compartments and industrial motor drives. |
| Lead-free & green compliance | Fully RoHS 2 compliant with <900 ppm Br, <900 ppm Cl, <1000 ppm Sb; suitable for eco-sensitive consumer and medical end equipment. |
Applications
| LED Driver Circuit | Logic-Level Translator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDC114YH-7 | VIN(on) = 0.3 V @ IO = 1 mA; lower threshold optimized for 1.8 V logic systems. | Suitable for ultra-low-voltage MCU interfaces where DDC114EH-7's 3.0 V threshold would cause incomplete turn-on. | Select DDC114YH-7 only when driving from sub-2.5 V sources; otherwise DDC114EH-7 provides better noise immunity. |
| DDC123JH-7 | R1 = 2.2 kΩ, R2 = 47 kΩ; higher gain (GI = 80) but reduced input voltage range (VIN = –5 to +12 V). | Better suited for low-current sensing amplifiers requiring high input impedance and minimal loading of source signals. | Choose DDC123JH-7 when interfacing high-impedance analog sensors; DDC114EH-7 remains optimal for robust digital switching. |
Compared with DDC114YH-7 and DDC123JH-7, DDC114EH-7 offers balanced input threshold, standardized 10 kΩ biasing, and widest operating voltage range (–10 V to +40 V), making it the default choice for general-purpose 3.3 V/5 V logic interfacing where reliability and design reuse matter.

FAQ
What is the maximum allowable junction temperature for DDC114EH-7?
The DDC114EH-7 is rated for a junction temperature range of –55°C to +150°C. This specification is validated per JEDEC standards and confirmed in the DS30421 Rev. 5 datasheet, page 2. Operation beyond +150°C risks permanent parametric shift and accelerated failure mechanisms.
Can DDC114EH-7 replace discrete transistor + resistor combinations in existing designs?
Yes - DDC114EH-7 directly replaces two NPN transistors with their associated base bias resistors (10 kΩ each) in dual-channel configurations. Layout changes are limited to SOT-563 footprint adoption; no revalidation of timing or gain is needed due to matched internal resistor tolerances and characterized VCE(sat) behavior.
Does DDC114EH-7 support bidirectional signal routing?
No - DDC114EH-7 is a unidirectional NPN switch with fixed emitter-common topology. It functions only as a current sink; reverse current flow (e.g., from collector to input pin) is blocked by internal resistor isolation and lacks ESD protection diodes for bidirectional use.
Is the SOT-563 package compatible with standard reflow profiles?
Yes - DDC114EH-7 meets J-STD-020 Level 1 moisture sensitivity and is qualified for standard lead-free reflow profiles (peak 260°C, 60-second duration above 217°C). The matte tin finish on copper leadframe ensures reliable solder wetting per MIL-STD-202, Method 208.
