DDTC114ECA-7-F

Overview

The DDTC114ECA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction with built-in biasing resistors where R1 equals R2, both nominally 10 kΩ. The device operates with a supply voltage of up to 50 V and a maximum collector current of 100 mA. Power dissipation is rated at 200 mW, with a junction-to-ambient thermal resistance of 625 °C/W. It supports a gain-bandwidth product of 250 MHz and functions within a temperature range of -55°C to +150°C. Packaged in SOT-23, it meets AEC-Q101 standards for high reliability.

Feature Summary

• Epitaxial planar die construction with integrated equal-value biasing resistors (R1 = R2).
• Qualified to AEC-Q101 automotive standards for high reliability applications.
• Totally lead-free, halogen-free, and antimony-free green device compliant with RoHS directives.

Applications

• Automotive electronic circuits requiring AEC-Q101 qualified components.
• General-purpose switching and logic interface applications.
• Driver circuits for low-power loads utilizing pre-biased transistor configurations.

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the standard 3,000-unit reel size in the SOT-23 package. Confirm that the 'CA' series designation matches the required R1=R2 resistor configuration. Ensure compliance with RoHS 3 and REACH regulations if applicable to the target market. Check for PPAP capability requirements if used in automotive supply chains.

Selection Notes

Select this component when a single NPN transistor with matched internal base and emitter resistors is required. The 10 kΩ nominal resistance value suits standard logic level interfacing. Consider the 200 mW power dissipation limit and 625 °C/W thermal resistance for adequate heat management on FR4 PCBs. Verify input voltage limits (-10V to +40V) against the application's signal swing.

Part Context

This part belongs to the DDTC (R1=R2 Series) CA family from Diodes Incorporated. It is distinct from other variants like the DDTC123ECA or DDTC143ECA which feature different resistor values (2.2kΩ and 4.7kΩ respectively). The 'CA' suffix indicates the specific SOT-23 package and resistor matching characteristics defined in datasheet DS30329.

Replacement Considerations

For automotive versions, consider ADTC114ECAQ as specified in the ordering information notes. Standard replacements must match the 100mA current rating, 50V voltage rating, and 10kΩ dual resistor configuration in an SOT-23 package.
