DDTA123JCA-7

Overview

The DDTA123JCA-7-F is a PNP pre-biased transistor from Diodes Incorporated, housed in an SOT-23 package. It integrates internal biasing resistors R1 (2.2 kΩ) and R2 (47 kΩ). The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Electrical characteristics include a minimum DC current gain of 80 at 10 mA and 5 V, with a transition frequency of 250 MHz. Power dissipation is rated at 200 mW, and the operating temperature range spans from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Surface-mount package optimized for automated assembly

Applications

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

Procurement Notes

Verify the complete part number against official distributor catalogs to ensure correct suffixes. Confirm RoHS compliance status through manufacturer documentation before procurement. Validate component authenticity via authorized supply channels to prevent counterfeit risks.

Selection Notes

Select this component when a PNP configuration with specific 2.2 kΩ and 47 kΩ resistor values is required. Ensure the 50 V voltage rating and 100 mA current capacity meet the application demands. Verify thermal management requirements align with the 200 mW power dissipation limit in the target environment.

Part Context

This component belongs to the DDTA(R1≠R2) Series CA family, which includes various PNP pre-biased transistors with different resistor combinations. It serves as the complementary counterpart to the DDTC series NPN types within the same product line.

Replacement Considerations

Direct substitutes include other DDTA123JCA variants from Diodes Incorporated. Cross-manufacturer equivalents must match the 50 V rating, 100 mA current, and identical resistor ratios.
