DDTC123EE-7

Overview

The DDTC123EE-7 is an NPN pre-biased transistor manufactured by Diodes Incorporated, housed in a SOT523 surface-mount package. It features built-in biasing resistors with nominal values of R1 = R2 = 2.2 kΩ. The device supports a supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 20 at 5 V and 20 mA, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• RoHS compliant and halogen-free green device

Applications

• General-purpose switching applications
• Driver circuits for small signal loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as reel size and tape width. Confirm compliance requirements including RoHS and lead-free status directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a compact NPN pre-biased solution with 2.2 kΩ internal resistors is required. Ensure the application operates within the 50 V supply limit and 100 mA current capacity. Consider thermal derating curves if ambient temperatures exceed standard operating ranges.

Part Context

This part belongs to the DDTC (R1 = R2 Series) EE family from Diodes Incorporated. Complementary PNP types are available under the DDTA series. The EE suffix denotes the SOT523 package variant designed for surface mount assembly processes.
