DDTA114EKA-7-F

Overview

The DDTA114EKA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and built-in biasing resistors where R1 equals R2, with a nominal value of 10 kOhms. The device operates within a supply voltage range up to -50 V and supports a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, and the junction temperature range spans from -55°C to +150°C. It is housed in an SC-59 package.

Feature Summary

• Integrates dual biasing resistors (R1 = R2) for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Complements NPN types within the DDTC series

Applications

• General-purpose switching applications
• Driver circuits requiring integrated biasing
• Logic interface circuits

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status based on manufacturing date codes, as older units may contain halogens or Sb2O3 fire retardants. Ensure proper handling procedures are followed during assembly to maintain moisture sensitivity level 1 integrity.

Selection Notes

Select this component when a PNP configuration with equal internal base and emitter resistors is required. Verify that the SC-59 package dimensions fit the target PCB layout. Consider the thermal resistance of 625 °C/W and derating curves if operating near maximum power dissipation limits.

Part Context

This part belongs to the DDTA114 series of pre-biased transistors. It serves as the PNP counterpart to the DDTC114 series. The 'KA' suffix indicates the specific SC-59 package type and resistor values. Other variants in the series include different resistance values such as 2.2KΩ or 4.7KΩ.

Replacement Considerations

Direct substitutes include other DDTA114EKA-7-F units from Diodes Incorporated. Cross-referencing with DDTC114EKA-7-F is only suitable if NPN polarity is acceptable. Verify pinout compatibility before replacing.
