DDTA114YUA-7-F

Overview

The DDTA114YUA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT-323 case. The device integrates internal biasing resistors with nominal values of R1 = 10 kΩ and R2 = 10 kΩ. Maximum ratings include a supply voltage (VCC) of -50 V, an output current (IO) of -70 mA, and power dissipation (Pd) of 200 mW at 25°C ambient temperature. The operating and storage temperature range spans from -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors with unequal resistance values for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Complements available 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 distribution channels. Confirm RoHS compliance status and manufacturing date codes against current datasheet specifications. Ensure proper handling procedures are followed during assembly to maintain moisture sensitivity level integrity.

Selection Notes

Select this component when a PNP pre-biased transistor with specific 10kΩ resistor ratios is required. Verify that the -70 mA output current rating meets application demands. Consider thermal resistance characteristics for high-power dissipation scenarios.

Part Context

This part belongs to the DDTA (R1≠R2 Series) UA family of pre-biased transistors. It shares the SOT-323 package form factor with other variants like DDTA113ZUA and DDTA144VUA. The 'UA' suffix indicates the specific SOT-323 casing style used across this product line.

Replacement Considerations

DDTA114WUA-7-F offers similar functionality with different resistor values. DDTA114ECAQ-13-F provides automotive qualification in a different package. Verify pin compatibility and electrical parameters before substitution.
