DDTA113TKA-7-F

Overview

The DDTA113TKA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction in an SC-59 package. The device integrates a single built-in biasing resistor (R1) with a nominal value of 1 kΩ. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and power dissipation (Pd) of 200 mW at 25°C. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = -1mA. Operating temperatures span from -55°C to +150°C.

Feature Summary

• Integrates a single built-in biasing resistor for simplified circuit design
• Utilizes epitaxial planar die construction for reliability
• Available in lead-free RoHS compliant packaging

Applications

• General purpose switching applications
• Driver circuits requiring integrated base biasing
• Low voltage digital logic interfacing

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to ensure correct packaging and compliance status. Confirm that the SC-59 package dimensions match the target PCB footprint requirements. Check for any updates regarding the 'Green' molding compound status if manufacturing date codes are critical for halogen-free specifications.

Selection Notes

Select this component when a PNP configuration with a 1 kΩ base resistor is required. Compare hFE gain ranges and saturation voltages against load requirements. Ensure the thermal resistance characteristics fit the ambient temperature constraints of the application environment.

Part Context

This part belongs to the DDTA R1-only series from Diodes Incorporated. It serves as the PNP counterpart to the DDTC NPN series. The 'KA' designation indicates the SC-59 surface mount package. Other variants in this series offer different resistor values such as 2.2 kΩ or 4.7 kΩ.

Replacement Considerations

Direct functional substitutes within the same family include DDTA123TKA-7-F and DDTA143TKA-7-F, which share identical electrical ratings but differ in internal resistor values. Verify pinout compatibility before substitution.
