DDTC113TUA-7-F

Overview

The DDTC113TUA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction with a built-in single biasing resistor (R1) of 1kΩ nominal value. The device operates within a collector-emitter voltage range of up to 50V and supports a continuous collector current of 100mA, with a power dissipation rating of 200mW at 25°C ambient temperature. Packaged in a compact SOT-323 form factor, it offers a DC current gain (hFE) ranging from 100 to 600 and a gain-bandwidth product of 250MHz. The component is fully RoHS compliant, halogen-free, and antimony-free.

Feature Summary

• Epitaxial planar construction with integrated R1 biasing resistor
• Surface mount package optimized for automated assembly processes
• Environmentally compliant material composition without halogens or antimony

Applications

• Automotive electronic systems requiring specific change control protocols
• General purpose switching applications utilizing surface mount technology
• Embedded circuits requiring compact NPN transistor solutions with integrated biasing

Procurement Notes

Verify the ordering suffix matches the required packing quantity and carrier type. Confirm that the active status aligns with long-term production availability requirements. Ensure compliance with automotive quality standards if the application demands AEC-Q100 qualification or IATF 16949 manufacturing certification. Cross-reference the date code key for production year identification upon receipt.

Selection Notes

Select this component when a low-profile SOT-323 package is necessary for space-constrained designs. Choose the 1kΩ input resistance variant for specific base drive requirements. Verify thermal management capabilities against the 625 °C/W junction-to-ambient thermal resistance specification. Ensure the operating temperature range of -55°C to +150°C meets the environmental conditions of the target system.

Part Context

This part belongs to the DDTC(R1-only) series UA family, which includes various NPN pre-biased transistors differentiated primarily by their internal resistor values. The 'UA' suffix denotes the specific SOT-323 surface mount package configuration. The '-7-F' suffix indicates a standard reel packaging format containing 3,000 units per 7-inch reel with an 8mm tape width.

Replacement Considerations

Direct substitutes within the same series include DDTC123TUA-7-F (2.2kΩ), DDTC143TUA-7-F (4.7kΩ), DDTC114TUA-7-F (10kΩ), DDTC124TUA-7-F (22kΩ), DDTC144TUA-7-F (47kΩ), DDTC115TUA-7-F (100kΩ), and DDTC125TUA-7-F (200kΩ). Selection depends on matching the required input resistance value while maintaining identical electrical characteristics and package dimensions.
