DDTC123JCA-7-F

Overview

The DDTC123JCA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrates internal biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 47 kΩ. The device operates within a supply voltage range up to 50 V and supports a maximum continuous collector current of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 80 at 10 mA, a transition frequency (fT) of 250 MHz, and a maximum power dissipation of 200 mW in the SOT-23 package.

Feature Summary

• Integrates two distinct biasing resistors (R1 ≠ R2) to simplify circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Complies with AEC-Q101 standards for high reliability applications

Applications

• General-purpose switching circuits requiring integrated biasing
• Driver stages for low-power loads
• Logic interface circuits for level shifting or buffering

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and lead-free status against current manufacturing declarations. Ensure storage conditions adhere to moisture sensitivity level 1 requirements per J-STD-020 specifications before soldering.

Selection Notes

Select this part when an NPN configuration with specific 2.2 kΩ base and 47 kΩ emitter resistor ratios is required. Compare hFE minimums and saturation voltages against load requirements. Verify thermal resistance constraints for the intended ambient temperature environment.

Part Context

This component belongs to the DDTC (R1≠R2 Series) CA family from Diodes Incorporated. It serves as the NPN counterpart to the DDTA series PNP devices. The suffix -7-F indicates standard reel packaging with 3,000 units per 7-inch tape.

Replacement Considerations

Direct substitutes within the same manufacturer family include DDTC123YCA-7-F (different resistor values). Cross-manufacturer equivalents require matching NPN polarity, SOT-23 footprint, and electrical ratings.
