DDTA114YKA-7-F

Overview

The DDTA114YKA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SC-59 package. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 10 kΩ. The device supports a supply voltage (VCC) of -50 V and a continuous collector current (IO) of -100 mA. Power dissipation is rated at 200 mW, with a DC current gain (Gl) minimum of -68. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated unequal biasing resistors simplify circuit design
• RoHS compliant and lead-free manufacturing

Applications

• General-purpose switching applications
• Driver circuits for logic interfaces
• Biasing networks in analog signal processing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging and compliance details. Ensure that the SC-59 footprint matches the target PCB layout requirements. Confirm environmental specifications such as moisture sensitivity level and flammability rating before finalizing procurement decisions.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required. The SC-59 package offers a compact solution for space-constrained designs. Consider the -100 mA current capability and -50 V voltage rating to ensure adequate headroom for the intended application load conditions.

Part Context

This part belongs to the DDTA series of pre-biased transistors manufactured by Diodes Incorporated. The 'KA' designation indicates the SC-59 package type. The '114Y' code specifies the internal resistor ratio and values within the product family.

Replacement Considerations

Check for direct substitutes within the same manufacturer's portfolio or equivalent parts from other vendors. Verify pinout compatibility and electrical parameter alignment, particularly regarding maximum ratings and thermal resistance characteristics.
