DDA124EK-7-F

Overview

The DDA124EK-7-F is a single PNP digital transistor manufactured by Diodes Incorporated, belonging to the DDA124 series. It features an epitaxial planar construction with built-in biasing resistors and is totally lead-free. The device operates within a collector-emitter voltage (VCEO) of 50 V and supports a continuous collector current of 100 mA. Power dissipation is rated at 300 mW. The typical input resistance is 22 kOhms, with a minimum DC collector/base gain (hFE) of 56. It functions in a dual configuration environment but contains a single PNP transistor unit. The component is housed in a SOT-26-6 package and operates between -55°C and +150°C.

Feature Summary

• Integrated pre-biasing resistors simplify circuit design by reducing external component count.
• Epitaxial planar construction ensures robust performance and reliability.
• Totally lead-free composition complies with environmental standards.

Applications

• General-purpose switching applications requiring compact surface-mount solutions.
• Driver circuits for low-power loads where space constraints are critical.
• Logic interface circuits utilizing standard TTL or CMOS levels.

Procurement Notes

Verify current availability status as the component is listed with an End-of-Life lifecycle stage. Confirm final assembly and wafer source details through official Product Change Notifications prior to procurement.
