DDTA122LE-7-F

Overview

The DDTA122LE-7-F is a PNP pre-biased surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT-523 package. The device integrates built-in biasing resistors, specifically R1 at 0.22 kΩ and R2 at 10 kΩ. Key electrical ratings include a maximum collector-emitter voltage of -40 V, a continuous collector current of -100 mA, and power dissipation of 150 mW. The component operates within a temperature range of -55°C to +150°C and meets RoHS compliance standards.

Feature Summary

Integrates built-in biasing resistors for simplified circuit design
Utilizes epitaxial planar die construction for reliability
Available in lead-free SOT-523 surface mount packaging

Applications

Switching applications requiring integrated base drive
Driver circuits for logic level translation
General purpose amplification stages

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct resistor values and marking codes. Confirm that the procurement channel provides valid traceability for the component's manufacturing date code and lot information. Ensure compatibility with standard surface mount assembly processes.

Selection Notes

Select this component when a compact PNP solution with fixed internal biasing is required. The SOT-523 package offers a small footprint suitable for space-constrained designs. Verify that the -100 mA current rating and -40 V voltage limits align with the target application's operational requirements.

Part Context

This part belongs to the DDTA series of pre-biased transistors from Diodes Incorporated. It is designed as a complementary counterpart to NPN types within the same family. The series emphasizes miniaturization through integrated passive components, reducing the external component count in switching and driver circuits.

Replacement Considerations

Direct substitutes within the same series include the DDTA122TE-7-F, which shares identical resistor values but differs in marking code. Designers should verify pinout compatibility and thermal characteristics before substituting.
