Diodes Incorporated DDTC114YLP-7

Overview

DDTC114YLP-7 from Diodes Incorporated is an NPN pre-biased digital transistor with integrated R1=10kΩ and R2=47kΩ bias resistors in a DFN1006-3 (X1) package, rated for 50V V_CBO, 70mA I_O, and 250mW power dissipation, used for logic-level signal switching in space-constrained consumer and industrial control circuits.

For engineers reviewing the DDTC114YLP-7 datasheet, DDTC114YLP-7 pinout, DDTC114YLP-7 application, or DDTC114YLP-7 equivalent, key selection criteria include input-on voltage (1.1V), collector-emitter saturation voltage (0.15V at 10mA), DC current gain (50–180), thermal resistance (500°C/W), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This device integrates two precision thin-film resistors (R1=10kΩ ±30%, R2=47kΩ) on a single epitaxial planar NPN die to enable direct TTL/CMOS interface without external bias components. It operates as a saturated switch with guaranteed V_CE(SAT) ≤0.15V at I_C=10mA/I_B=1mA and supports input voltages up to +40V.

The X1-DFN1006-3 package features an exposed collector pad for thermal conduction, NiPdAu-plated terminals compliant with MIL-STD-202 Method 208, and moisture sensitivity level 1 per J-STD-020 - enabling high-yield reflow assembly in ultra-compact PCB layouts.

FAQ

What is the maximum continuous collector current for DDTC114YLP-7?

The maximum continuous output current (I_O) is 70 mA under steady-state conditions at T_A = +25°C. Derating applies above +25°C at 2 mW/°C, and absolute maximum collector current (I_C(MAX)) is 100 mA under pulsed conditions (≤300 µs, ≤2% duty cycle).

Does DDTC114YLP-7 require external bias resistors?

No - it integrates precision R1=10 kΩ and R2=47 kΩ thin-film resistors on-die, eliminating external bias components. The internal configuration provides fixed base current scaling and ensures consistent saturation behavior across temperature and process variation.

Is DDTC114YLP-7 compatible with lead-free reflow soldering processes?

Yes - it is fully RoHS 2 compliant, uses NiPdAu-plated terminals qualified per MIL-STD-202 Method 208, and has moisture sensitivity level 1, allowing direct placement onto PCBs without pre-baking and compatibility with standard Pb-free reflow profiles (peak ≤260°C).

How does the DFN1006-3 package affect thermal performance?

The X1-DFN1006-3 package achieves R_θJA = 500°C/W on a single-sided 1.6 mm FR4 board with minimum recommended copper pad layout. Its exposed collector pad must be connected to a thermal land to realize this rating; insufficient copper area increases junction temperature and requires additional derating.
