DDTA123JCA-7-F

Overview

The DDTA123JCA-7-F is a PNP pre-biased transistor from the DDTA (R1≠R2 SERIES) CA family, manufactured by Diodes Incorporated. It integrates biasing resistors within an SOT-23 surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features a typical input resistor (R1) of 2.2 kΩ and a resistance ratio (R2/R1) of 0.047. Minimum DC current gain is specified at 80, with a power dissipation rating of 200 mW. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Built-in biasing resistors simplify circuit design
• Surface-mount package suited for automated assembly

Applications

• General-purpose switching applications
• Driver circuits requiring integrated biasing
• Automotive electronics (subject to specific qualification requirements)

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm RoHS compliance and lead-free status against current regulatory standards. Ensure packaging specifications match production line requirements. Validate datasheet revision compatibility before integration into final designs.

Selection Notes

Select this component when a PNP configuration with specific internal resistance ratios is required. Verify that the -50 V voltage rating and -100 mA current capacity meet system demands. Consider thermal resistance characteristics for heat dissipation planning in enclosed environments.

Part Context

This part belongs to the DDTA series of pre-biased transistors. It complements the DDTC NPN types within the same product family. The 'CA' suffix indicates specific pinout and marking conventions. The '-7-F' suffix denotes reel packaging with lead-free composition.

Replacement Considerations

Direct substitutes include other DDTA123 variants with matching resistance values, such as DDTA123YCA or DDTA123TCA, provided their specific R1/R2 ratios align with design requirements. Cross-reference electrical limits carefully.
