IMX17T110

Overview

The IMX17T110 is a general-purpose isolated dual transistor manufactured by Rohm Semiconductor. It integrates two independent PNP bipolar junction transistors (BJTs) within a single surface-mount SMT6 package, which corresponds to the SC-74 or SOT-457 form factor. The device features a maximum collector current of 500mA and a collector-emitter breakdown voltage of 50V. Key electrical specifications include a DC current gain (hFE) of at least 120 measured at 100mA and 3V, a transition frequency of 200MHz, and a maximum power dissipation of 300mW. The saturation voltage is specified at a maximum of 600mV under defined base and collector current conditions.

Feature Summary

• Contains two electrically isolated PNP transistor elements to prevent signal interference between channels.
• Maintains identical physical dimensions to the standard SMT3 package for compatibility with existing mounting equipment.
• Provides high collector current capability suitable for small-signal amplification tasks.

Applications

• General purpose small signal amplifier circuits
• Switching applications requiring compact dual-channel solutions

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required tape-and-reel quantity. Check the official datasheet for the most recent status updates, as availability may vary. Ensure the package type aligns with your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when space constraints require dual PNP transistors in an SMT3-compatible footprint. Consider the 500mA current limit and 50V voltage rating against circuit demands. Evaluate the 200MHz transition frequency for high-speed switching needs. Compare thermal performance based on the 300mW power dissipation limit in your specific enclosure environment.

Part Context

This part belongs to Rohm's series of general-purpose isolated dual transistors. These components are designed to replace discrete dual setups, reducing board area and assembly costs. The isolation feature distinguishes them from common-base or common-emitter dual configurations, offering independent operation for each transistor element within the shared package.

Replacement Considerations

Direct substitutes include other isolated dual PNP transistors in SOT-457 packages such as the UMT1N or IMX9 from Rohm. Cross-manufacturer equivalents like those from Diodes Incorporated or Unisonic Technologies should be verified for pinout compatibility and electrical parameter matching before integration.
