DDTA123EKA-7-F

Overview

The DDTA123EKA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates built-in biasing resistors where R1 equals R2, with a nominal resistance of 2.2 kΩ. 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 built-in biasing resistors with a ratio of R1 to R2 equal to one
• Utilizes epitaxial planar die construction for reliable performance
• Complies with RoHS standards and utilizes green molding compound

Applications

• General-purpose switching applications requiring integrated biasing
• Driver circuits for logic interfaces
• Low-power digital signal processing systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ordering suffix matches the specific packaging requirements. Ensure compliance with environmental regulations regarding lead-free plating and halogen content based on the manufacturing date code.

Selection Notes

Select this component when a single PNP transistor with integrated base and emitter resistors is required. The 2.2 kΩ resistor value suits standard logic interface applications. Consider the SC-59 package dimensions for PCB layout constraints and verify thermal management needs against the specified power dissipation rating.

Part Context

This part belongs to the DDTA (R1 = R2) series of pre-biased transistors from Diodes Incorporated. It serves as the PNP counterpart to the DDTC NPN series. The 'KA' designation indicates the SC-59 case style, while the '-7-F' suffix specifies tape and reel packaging containing 3000 units per reel.

Replacement Considerations

Compatible substitutes include other DDTA123 variants with different packages such as DDTA123ECA-7-F (SOT-23-3) or DDTA123TCA-7-F (SOT-23-3). Verify pinout compatibility and electrical parameters before substitution.
