DDTA122LE-7

Overview

The DDTA122LE-7 is a PNP pre-biased surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT-523 case with molded plastic material rated UL 94V-0. The device integrates built-in biasing resistors, specifically R1 at 0.22 kOhms and R2 at 10 kOhms. Key electrical ratings include a collector-emitter breakdown voltage of -40 V, continuous collector current of -100 mA, and power dissipation of 150 mW. It operates within a temperature range of -55 to +150 °C.

Feature Summary

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

Applications

Switching applications requiring integrated biasing
Driver circuits for low-power loads
General-purpose digital logic interfacing

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status as indicated on the datasheet. Check for end-of-life notifications or discontinuance alerts from the manufacturer prior to finalizing procurement plans. Ensure storage conditions align with moisture sensitivity level requirements.

Selection Notes

Select this component when a PNP configuration with specific 0.22 kOhm input resistance is required. Verify that the -40 V collector-emitter voltage rating meets the circuit's maximum operating voltage. Consider the SOT-523 footprint constraints during PCB layout. Compare against complementary NPN types if symmetrical switching is needed.

Part Context

This part belongs to the DDTA series of pre-biased transistors from Diodes Incorporated. It is designed to replace discrete resistor-transistor networks, reducing board space and assembly complexity. The 'LO-R1' designation indicates the specific resistor ratio configuration within the product family.

Replacement Considerations

Direct substitutes may include other DDTA series parts with matching resistor values. Complementary NPN versions are available under the DDTC series. Verify pinout compatibility and thermal characteristics before substitution.
