IMT17-7

Overview

The IMT17-7 is a dual PNP small signal surface mount transistor manufactured by Diodes Incorporated. It integrates two independent PNP transistors within a single compact package, designed for general-purpose amplification and switching applications. The device features an isolated structure to prevent interference between the two elements. Key electrical specifications include a maximum collector current (IC) of -500mA and a collector-emitter voltage (VCEO) of -50V. The component utilizes a SOT-363 compatible footprint, facilitating automated surface-mount assembly while reducing board space and mounting costs compared to discrete solutions.

Feature Summary

• Integrates two independent PNP transistor chips in a single surface-mount package
• Isolated element design eliminates internal interference between transistors
• High collector current capability for general-purpose signal processing
• Compact footprint reduces mounting area and simplifies assembly processes

Applications

• General purpose small signal amplification circuits
• Low-power switching applications in consumer electronics
• Signal conditioning stages in audio equipment

Procurement Notes

Verify the exact ordering code against the manufacturer's current catalog to ensure compatibility with required tape-and-reel quantities. Confirm that the suffix matches the specific packaging variant needed for your production line. Cross-reference the datasheet revision date to ensure all electrical parameters align with your design specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints require dual PNP functionality in a minimal footprint. Ensure the application voltage does not exceed the -50V VCEO rating. Consider the thermal characteristics if multiple units are placed closely on the PCB. Verify that the -500mA current rating meets the load requirements of the target circuit design.

Part Context

This part belongs to the family of dual PNP small signal transistors offered by Diodes Incorporated. It serves as a surface-mount alternative to through-hole discrete pairs. The IMT17-7 shares functional similarities with other dual PNP packages but is distinguished by its specific pinout and isolation characteristics defined in the official datasheet.

Replacement Considerations

Check for direct replacements such as the standard IMT17 or IMT17-7 from other manufacturers like Rohm or Unisonic Technologies. Verify pin-to-pin compatibility and identical electrical ratings before substitution. Ensure the replacement package type matches the existing PCB footprint exactly.
