DDTC114WE-7-F

Overview

The DDTC114WE-7-F is an NPN pre-biased transistor manufactured by Diodes Incorporated, housed in a SOT523 surface-mount package. It integrates two distinct biasing resistors (R1 and R2) to facilitate direct interfacing with logic circuits. The device features a supply voltage rating of 50 V and supports a maximum continuous collector current of 100 mA. Electrical characteristics include a typical transition frequency of 250 MHz and a power dissipation capacity of 150 mW. Internal resistor values are nominally 10 kΩ for R1 and 47 kΩ for R2.

Feature Summary

• Epitaxial planar die construction ensures stable performance across operating conditions.
• Integrated unequal biasing resistors simplify circuit design by eliminating external components.
• Halogen-free and antimony-free "Green" device compliant with environmental directives.

Applications

• General-purpose switching applications
• Driver circuits for relays and solenoids
• Logic level translation interfaces

Procurement Notes

Verify the complete part number including the -7-F suffix to confirm reel packaging specifications. Confirm RoHS 3 compliance status through official manufacturer channels prior to procurement. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to maintain solderability and device integrity during assembly processes.

Selection Notes

Select this component when a compact NPN digital transistor with specific unequal bias ratios is required. The 10 kΩ input resistor provides appropriate base drive for standard logic outputs. Verify that the 100 mA output current capability meets the load requirements of the intended application circuit before finalizing the design.

Part Context

This component belongs to the DDTC (R1≠R2 Series) E family from Diodes Incorporated. It serves as a complementary counterpart to PNP devices within the DDTA series. The SOT523 package offers a small footprint suitable for high-density PCB layouts compared to larger transistor packages.

Replacement Considerations

Direct functional substitutes within the same series include DDTC114YE-7-F and DDTC124XE-7-F. These alternatives share identical SOT523 packaging and electrical ratings but feature different nominal resistor values. Verify specific resistance ratios against design requirements before substitution.
