DDTC144GCA-7

Overview

The DDTC144GCA-7 is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SOT-23 package. It features an epitaxial planar die construction with a built-in biasing resistor (R2 only) of 47 kΩ nominal value. The device supports a maximum collector-emitter voltage (VCEO) and collector-base voltage (VCBO) of 50 V, with a continuous collector current rating of 100 mA and power dissipation of 200 mW at 25°C ambient temperature. It operates within a temperature range of -55°C to +150°C.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated single biasing resistor simplifies circuit design
Lead-free plating with matte tin finish over alloy leadframe
RoHS compliant green device free of purposefully added lead

Applications

Switching applications requiring simplified base drive circuits
Low-voltage logic interface circuits
General-purpose digital switching tasks

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The standard factory packaging quantity is 3000 units per tape and reel. Confirm that the component meets RoHS standards and check for any halogen or antimony content variations based on the manufacturing date code. Ensure compatibility with the recommended pad layout specified in application notes.

Selection Notes

Select this component when a single NPN pre-biased transistor with a 47 kΩ internal resistor is required. The SOT-23 package offers a compact footprint suitable for space-constrained designs. Consider the 200 mW power dissipation limit and thermal resistance characteristics during high-current operation. Verify that the 50 V voltage ratings align with the system's maximum operating conditions.

Part Context

This part belongs to the DDTC (R2-only series) CA family from Diodes Incorporated. The 'GCA' designation indicates the SOT-23 case style and specific marking code. The suffix '-7' typically denotes the standard tape and reel packaging format used for automated assembly processes.

Replacement Considerations

Direct substitutes include other NPN pre-biased transistors with similar 47 kΩ internal resistors and SOT-23 packaging. Verify electrical parameters such as VCEO, IC, and hFE before substitution. Check pinout compatibility and thermal characteristics to ensure equivalent performance in the target application.
