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.

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.
