Product details

Overview

DDTA114YLP-7 from Diodes Incorporated is a 50V PNP pre-biased small-signal transistor in X1-DFN1006-3 package, integrating 10kΩ and 47kΩ bias resistors. It delivers h_FE ≥80 at I_C = −5mA, V_CE(sat) ≤ −0.25V at I_C = −50mA/I_B = −2.5mA, and operates from −55°C to +150°C. Used in automotive LED load switching and logic-level interface circuits.

For engineers reviewing the DDTA114YLP-7 datasheet, DDTA114YLP-7 pinout, DDTA114YLP-7 application, or DDTA114YLP-7 equivalent, key selection criteria include verified R₁/R₂ resistor values (10kΩ/47kΩ), AEC-Q101 qualification, ultra-small DFN1006 footprint, and guaranteed V_CE(sat) performance under −50mA load conditions.

Technical Context

This device integrates a PNP bipolar transistor with two monolithically embedded base bias resistors (R₁ = 10kΩ, R₂ = 47kΩ) in a single die. It functions as a digital switch with built-in pull-up and pull-down network, eliminating external bias components.

Designed for direct logic-level drive, it supports input voltage range of −40V to +6V and guarantees turn-on at V_I(on) ≤ −1.4V with I_O = −1mA. Its f_T = 250MHz enables stable operation in high-speed switching applications up to several MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50V - Maximum collector-emitter blocking voltage before breakdown
h_FE	≥80 - DC current gain ensures reliable saturation with low base drive current
V_CE(sat)	≤−0.25V @ I_C=−50mA - Low on-state loss reduces power dissipation in load-switching paths
R₁, R₂	10kΩ / 47kΩ - Fixed internal bias network eliminates need for external resistors
P_D	250mW - Power rating defined on standard 1oz FR4 PCB with exposed collector pad thermal path
f_T	250MHz - Enables use in pulse-width modulation and fast digital switching up to ~10MHz

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP pre-biased transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DDTA114YU-7	Same electrical specs but in SOT-323 package (2.1×1.25mm); higher thermal resistance (R_θJA = 350°C/W)	Less suitable for space-constrained designs; better suited for manual prototyping or lower-power applications	Select when board real estate allows larger footprint and thermal budget permits higher junction temperature rise
NSVDDTA114YLT1G	AEC-Q101 qualified, identical R₁/R₂ and V_CEO, but rated for −65°C to +150°C operating range	Extended low-temperature capability required for cold-climate automotive deployments	Choose for enhanced reliability in extreme environments where −55°C minimum is insufficient

Compared with DDTA114YLP-7, DDTA114YU-7 trades miniaturization for easier handling and slightly better thermal performance in larger packages, while NSVDDTA114YLT1G extends operational range downward without altering switching characteristics-making it ideal for harsh-environment automotive systems.

FAQ

What is the function of the bar marking on the top view of DDTA114YLP-7?

The bar marking on the top view indicates the side containing the base (B) and emitter (E) terminals. This orientation aids visual identification during automated placement and manual inspection. The dot marking denotes the collector (C) side, aligning with the pin numbering convention shown in the datasheet's top-view diagram.

Can DDTA114YLP-7 be used in high-frequency switching applications above 10MHz?

Yes-its f_T of 250MHz supports stable operation in PWM-driven loads up to ~10MHz, provided layout minimizes parasitic inductance and the collector pad is properly thermally coupled. However, switching losses increase above 5MHz due to finite charge storage time; verify timing margins with actual gate-drive waveforms.

Is the exposed collector pad electrically isolated from other terminals?

No-the exposed collector pad is electrically connected to pin 3 (collector) and must be routed to the same net. It serves as both the primary current-carrying terminal and thermal conduction path. PCB design must ensure no unintended shorting to adjacent traces or planes, and thermal vias should connect it to inner-layer copper pours.

Does DDTA114YLP-7 require external base resistors for logic-level drive?

No-it contains monolithically integrated R₁ = 10kΩ and R₂ = 47kΩ bias resistors. These provide proper base current limiting and pull-down functionality, enabling direct connection to 3.3V or 5V microcontroller outputs without additional components.
