DDTC114GCA-7-F

Overview

The DDTC114GCA-7-F 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) of 10 kΩ nominal value. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA, with a power dissipation rating of 200 mW at 25°C ambient temperature. It operates within a temperature range of -55°C to +150°C and includes a minimum DC current gain (hFE) of 30.

Feature Summary

• Integrates a single internal biasing resistor (R2) to simplify circuit design and reduce component count.
• Utilizes epitaxial planar die construction for reliable performance in surface mount applications.
• Manufactured as a lead-free, halogen-free, and antimony-free 'Green' device compliant with RoHS standards.

Applications

• General-purpose switching circuits requiring simplified base drive networks.
• Driver stages for low-power loads where minimal external components are preferred.
• Logic interface applications utilizing the integrated biasing resistor for level shifting or pull-down functions.

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the tape and reel packaging configuration containing 3000 units per reel. Confirm that the required marking code 'N26' aligns with your assembly documentation requirements. Ensure compliance with the specified moisture sensitivity level and storage conditions prior to soldering.

Selection Notes

Select this component when a single NPN pre-biased transistor with a 10 kΩ internal resistor is required in a compact SOT-23 footprint. Consider the 50 V collector-emitter voltage and 100 mA current limits for appropriate load matching. Verify thermal resistance characteristics if operating near maximum power dissipation limits without adequate board cooling.

Part Context

This part belongs to the DDTC (R2-only series) CA family from Diodes Incorporated, designed specifically for applications needing a single integrated biasing resistor. It serves as the NPN counterpart to the DDTA series PNP devices, offering complementary options for digital transistor designs within the same package constraints.

Replacement Considerations

Direct functional substitutes may include other NPN pre-biased transistors with similar 10 kΩ R2 values and SOT-23 packaging, such as those from Nexperia or onsemi. Verify pinout compatibility and electrical parameters like VCEO and IC before substitution.
