DDTA115EKA-7-F

Overview

The DDTA115EKA-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 = 100 kΩ and R2 = 100 kΩ. The device supports a maximum collector-emitter voltage (VCC) of -50 V and a continuous collector current (IC) of -100 mA. Power dissipation is rated at 200 mW, with a transition frequency (fT) of 250 MHz. Operating temperature ranges from -55°C to +150°C.

Feature Summary

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

Applications

• General-purpose switching applications
• Driver circuits for logic interfaces
• Level shifting between different voltage domains

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging and compliance status. Ensure that the SC-59 footprint matches the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter resistors is required. The SC-59 package offers space savings compared to through-hole alternatives while maintaining standard electrical characteristics suitable for low-power digital switching tasks.

Part Context

This part belongs to the DDTA series of pre-biased transistors designed for surface mount technology. The 'KA' suffix indicates the SC-59 case style, distinguishing it from other packages like SOT-23 or SOT-323 within the same product family.

Replacement Considerations

Direct substitutes include other DDTA115 variants with different package styles such as DDTA115EUA-7-F (SOT-323) or DDTA115GCA-7-F (SOT-23), provided the physical footprint can be adapted.
