DDTC123JUA-7-F

Overview

The DDTC123JUA-7-F is a single NPN pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-323 surface-mount package. It integrates internal biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 47 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IOUT) of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at 10 mA output, a transition frequency (fT) of 250 MHz, and a maximum power dissipation of 200 mW. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated base and emitter biasing resistors simplify circuit design
• Surface mount package optimized for automated assembly processes
• Lead-free and fully RoHS compliant manufacturing

Applications

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

Procurement Notes

Verify the specific ordering suffix '-7-F' against official Diodes Incorporated documentation to confirm packaging details and compliance status. Confirm that the required resistor ratio tolerance aligns with the application's input requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with fixed 2.2kΩ/47kΩ biasing is required. Ensure the 200mW power dissipation limit and 100mA current capacity meet the target load specifications. Verify compatibility with the SOT-323 footprint during PCB layout.

Part Context

This part belongs to the DDTC (R1≠R2 Series) UA family of 50V NPN pre-biased transistors. It shares the same SOT-323 mechanical outline and core transistor structure as other variants in the series, distinguished primarily by its specific integrated resistor network configuration.

Replacement Considerations

Direct substitutes within the same series include DDTC123YUA-7-F (2.2kΩ/10kΩ) or DDTC143ZUA-7-F (4.7kΩ/47kΩ), provided the altered resistance ratios are acceptable for the circuit design.
