DDTC115TUA-7

Overview

The DDTC115TUA-7 is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and includes a built-in biasing resistor (R1) with a nominal value of 100 kΩ. The device operates within a collector-emitter voltage range up to 50 V and supports a continuous collector current of 100 mA. Power dissipation is rated at 200 mW, with a thermal resistance from junction to ambient air of 625 °C/W. The component is housed in an SOT323 package, suitable for automated assembly, and functions across an operating temperature range of -55°C to +150°C.

Feature Summary

Epitaxial planar die construction
Built-in biasing resistor R1 only
Surface mount package suited for automated assembly
Totally lead-free and fully RoHS compliant

Applications

Automated assembly processes
General-purpose switching applications
Driver circuits requiring integrated base biasing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packing quantity and carrier type. Confirm that the requested part number matches the active status listed in the manufacturer's ordering information table. Ensure compliance with environmental directives such as RoHS 3 and halogen-free requirements if specified for the application.

Selection Notes

Select this component when a single NPN pre-biased transistor with a 100 kΩ input resistor is required. Verify that the SOT323 package dimensions fit the PCB layout constraints. Check that the maximum ratings, including 50 V collector-emitter voltage and 100 mA collector current, align with the circuit design parameters.

Part Context

This component belongs to the DDTC (R1-ONLY SERIES) UA family from Diodes Incorporated. The series offers various nominal input resistor values, ranging from 1 kΩ to 200 kΩ, all sharing similar electrical characteristics and packaging. The 'UA' designation indicates the specific SOT323 package variant used for these surface-mount devices.

Replacement Considerations

Direct substitutes within the same series include DDTC114TUA-7-F (10 kΩ) or DDTC125TUA-7-F (200 kΩ), provided the resistor value difference is acceptable. Other manufacturers may offer equivalent NPN pre-biased transistors in SOT323 packages, but verification of pinout and electrical specifications is necessary.
