Overview
The DDTC144ELP-7 is a single NPN pre-biased small signal transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates two internal biasing resistors, R1 and R2, both nominally rated at 47 kΩ. The device operates with a maximum collector-emitter voltage of 50 V and supports a continuous collector current of 100 mA. It utilizes the X1-DFN1006-3 leadless surface mount package, which measures approximately 1.0 mm by 0.6 mm. The component is qualified to AEC-Q101 standards for high reliability and exhibits a transition frequency of 250 MHz.
Feature Summary
- Integrates dual biasing resistors (R1=R2) within a compact footprint to simplify circuit design.
- Utilizes an ultra-small leadless surface mount package suitable for automated assembly processes.
- Complies with AEC-Q101 standards to ensure high reliability in automotive applications.
Applications
- Automotive electronic systems requiring high-reliability switching components.
- General-purpose digital logic interface circuits.
- Low-voltage power management and load switching applications.
Procurement Notes
Verify the specific ordering suffix when sourcing components. The standard reel size contains 3,000 units, while the -7B variant contains 10,000 units per reel. Confirm that the requested part matches the required packaging quantity and tape width specifications before finalizing procurement orders to ensure compatibility with existing assembly equipment.
Selection Notes
Select this component when a compact NPN solution with integrated base and emitter resistors is required. The equal resistor ratio simplifies biasing calculations compared to asymmetric configurations. Ensure the PCB layout accommodates the exposed collector pad for thermal dissipation, as the package relies on copper area for heat management under steady-state conditions.
Part Context
This component belongs to the DDTC series of pre-biased transistors from Diodes Incorporated. It serves as the NPN counterpart to the DDTA144ELP PNP type. The device is designed to replace discrete transistor-resistor networks, reducing board space and assembly costs while maintaining consistent electrical characteristics across production batches.
Replacement Considerations
The complementary PNP equivalent is the DDTA144ELP. For pin-compatible replacements in SOT-23 packages, consider the DDTC144WCAQ-7 or DDTC144GCA, though package dimensions differ significantly.
