DDTC125TCA-7-F

Overview

The DDTC125TCA-7-F is an NPN pre-biased transistor from the R1-only series, housed in a surface-mount SOT-23 package. It features a built-in base resistor (R1) with a nominal value of 200 kΩ and a tolerance of ±30%. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning -55°C to +150°C. The DC current transfer ratio (hFE) ranges from 100 to 600 under specified test conditions.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated single biasing resistor (R1 only) simplifies circuit design
Totally lead-free and fully RoHS compliant manufacturing
Halogen and antimony free "Green" device composition

Applications

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

Procurement Notes

Verify component status before procurement as this specific part number is listed as obsolete in official documentation. Confirm availability through authorized distributors or secondary markets if immediate sourcing is required. Ensure that any replacement components maintain identical electrical characteristics and physical footprint specifications to guarantee compatibility with existing designs.

Selection Notes

Select this component when a high-value base resistor is required for low-current switching tasks. The 200 kΩ internal resistance limits base drive current significantly compared to lower resistance variants. Verify that the application's input voltage levels are sufficient to overcome the saturation voltage requirements given the high input impedance configuration.

Part Context

This component belongs to the DDTC (R1-ONLY SERIES) CA family manufactured by Diodes Incorporated. It serves as the NPN counterpart to the DDTA PNP series. The marking code for this device is N25 on the SOT-23 package. It shares mechanical dimensions and thermal characteristics with other members of the DDTC1xxTCA series.
