Overview
The DDTC144GCA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It utilizes epitaxial planar die construction and features a built-in biasing resistor (R2) with a nominal value of 47 kΩ. The device is housed in a SOT-23 package, measuring approximately 0.008 grams. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, a maximum collector current (IC) of 100 mA, and power dissipation (PD) of 200 mW at 25°C ambient temperature. The DC current transfer ratio (hFE) has a minimum value of 68 at IC = 5mA and VCE = 5V.
Feature Summary
- Integrates a single built-in biasing resistor to simplify circuit design and reduce component count.
- Constructed using epitaxial planar die technology for reliable performance.
- Manufactured as a lead, halogen, and antimony-free 'Green' device compliant with RoHS standards.
Applications
- Switching applications requiring simplified base drive circuits.
- Driver stages for low-power logic interfaces.
- General-purpose amplification in consumer electronics.
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to ensure correct packaging and marking codes. Confirm that the procurement source provides valid traceability data consistent with the manufacturer's quality standards. Ensure compliance with environmental regulations such as RoHS requirements before finalizing purchase orders.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required. The 47 kΩ internal resistor suits applications needing moderate base drive currents. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the target application circuit.
Part Context
This part belongs to the DDTC series of pre-biased transistors from Diodes Incorporated. It is specifically designed as an R2-only configuration within the CA sub-series. The device serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs.
Replacement Considerations
Direct substitutes include other DDTC series parts with matching resistor values, such as the DDTC124GCA-7-F or DDTC114GCA-7-F, provided the resistance tolerance and hFE characteristics align with the design specifications.
