DDTC123YE-7-F

Overview

The DDTC123YE-7-F is an NPN pre-biased transistor from Diodes Incorporated, housed in a SOT523 package. It features built-in biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 10 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 150 mW, with an operating temperature range spanning -55°C to +150°C. Transition frequency reaches 250 MHz.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated unequal biasing resistors simplify circuit design
• Totally lead-free and fully RoHS compliant
• Halogen and antimony free green device

Applications

• Switching applications requiring integrated biasing
• Driver circuits for logic interfaces
• General purpose amplification stages

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the reel packaging configuration. Confirm that the component meets the required environmental standards, including RoHS 3 compliance and halogen-free specifications, before finalizing procurement orders.

Selection Notes

Select this part when a compact NPN solution with fixed base and emitter resistors is needed. Ensure the 2.2 kΩ input resistor value aligns with the driving source impedance requirements. Verify that the 100 mA output current capability satisfies the load demands within the specified thermal limits.

Part Context

This component belongs to the DDTC(R1≠R2 Series) E family of pre-biased transistors. It serves as a single NPN unit designed to replace discrete resistor networks, reducing board space and assembly complexity compared to standard bipolar junction transistors without internal biasing.

Replacement Considerations

Direct substitutes include other DDTC series variants with matching pinouts but different resistance ratios, such as DDTC123ZE or DDTC123JE. Cross-reference electrical parameters like transition frequency and power dissipation to ensure compatibility.
