DDTA124GCA-7

Overview

The DDTA124GCA-7-F is a PNP pre-biased small signal transistor from Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a built-in biasing resistor (R2 only) with a nominal value of 22 kOhms. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA, with a power dissipation rating of 200 mW. It operates within a temperature range of -55°C to +150°C and includes a gain-bandwidth product of 250 MHz.

Feature Summary

• Integrates a single internal bleeder resistor (R2) for simplified circuit design
• Constructed using epitaxial planar die technology for high reliability
• Qualified to AEC-Q101 automotive standards for demanding environments

Applications

• Automotive electronic systems requiring high-reliability switching
• General-purpose digital logic interface circuits
• Low-power switching applications in consumer electronics

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status and manufacturing date codes prior to procurement. Ensure compatibility with standard SMT assembly processes and moisture sensitivity levels defined by J-STD-020D.

Selection Notes

Select this component when a PNP configuration with a 22 kOhm base resistor is required. Compare electrical characteristics such as saturation voltage and cutoff current against alternative discrete transistor solutions. Verify that the SOT-23 footprint aligns with existing PCB layout constraints.

Part Context

This part belongs to the DDTA R2-only series manufactured by Diodes Incorporated. It serves as a complementary counterpart to NPN types within the DDTC family. The device is designed to replace multiple discrete components, reducing board space and simplifying bias network design in compact electronic assemblies.

Replacement Considerations

Direct substitutes include other DDTA series variants with different resistance values. Cross-reference with DDTC models for NPN requirements. Verify pinout compatibility and thermal performance before substituting with generic discrete transistors.
