Overview
The DDTC115TE-7-F is an NPN pre-biased transistor from Diodes Incorporated, housed in a SOT-523 package. It features a built-in base resistor (R1) with a nominal value of 100 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and power dissipation of 150 mW. The device offers a DC current gain (hFE) ranging from 100 to 600 at IC = 1mA, VCE = 5V, and a transition frequency (fT) of 250 MHz. Operating temperature ranges from -55°C to +150°C.
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
- Halogen and antimony free "Green" device
Applications
- Automotive applications requiring specific change control
- General purpose switching circuits
- Driver circuits for low-power loads
Procurement Notes
Verify the exact ordering suffix against official documentation, as variations such as -7-F indicate specific packaging configurations like tape and reel quantities. Confirm compliance requirements including RoHS 3 and REACH status prior to procurement. Ensure the selected variant matches the required automotive or standard grade specifications if applicable to the target application environment.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required. The 100 kΩ internal resistor suits applications needing moderate base drive currents. Consider the SOT-523 package dimensions for space-constrained PCB layouts. Verify that the 50 V collector-emitter voltage rating aligns with the maximum operating voltage of the intended circuit to ensure safe operation under all conditions.
Part Context
This part belongs to the DDTC (R1-ONLY SERIES) E family, which includes various resistor values for different biasing needs. Complementary PNP types are available in the DDTA series. The device is manufactured in IATF 16949 certified facilities and is AEC-Q101 qualified for automotive use, ensuring high reliability and consistent quality standards across production batches.
Replacement Considerations
Direct substitutes include other NPN pre-biased transistors with similar R1 values and VCEO ratings. Check pinout compatibility and thermal resistance characteristics when replacing. Verify that the alternative component meets the same RoHS and halogen-free requirements to maintain regulatory compliance in the final assembly.
