DDTC114GKA-7-F

Overview

The DDTC114GKA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, featuring epitaxial planar die construction. It integrates a single built-in biasing resistor (R2) with a nominal value of 10 kΩ within an SC-59 case. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and power dissipation (Pd) of 200 mW. The device exhibits a minimum DC current transfer ratio (hFE) of 30 at IC = 5 mA and operates across a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single built-in biasing resistor for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Available in a compact SC-59 surface mount package

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Ensure compliance with RoHS standards and lead-free plating requirements as specified by the manufacturer. Confirm moisture sensitivity level and storage conditions prior to assembly to maintain component integrity during surface mount processes.

Selection Notes

Select this component when a single NPN transistor with a fixed base resistor is required. The 10 kΩ internal resistor value suits standard logic interface applications. Consider the SC-59 footprint constraints and thermal resistance characteristics relative to the available board space and heat dissipation capabilities of the target PCB layout.

Part Context

This part belongs to the DDTC R2-only series, which includes complementary PNP types (DDTA). The KA suffix denotes the SC-59 package style. Other variants in this series offer different resistor values such as 22 kΩ, 47 kΩ, and 100 kΩ, sharing similar electrical characteristics but differing in input impedance specifications.

Replacement Considerations

Direct substitutes include other DDTC114GKA variants from Diodes Incorporated or equivalent NPN pre-biased transistors in SC-59 packages from other manufacturers, provided they match the 10 kΩ resistor tolerance and 50 V/100 mA ratings.
