Procurement Notes

Verify the specific suffix TPL3 against official Toshiba documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure compatibility with RoHS3 directives if required by your manufacturing standards. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as supply chain conditions may vary. Always consult the latest datasheet for handling and storage recommendations.

Selection Notes

Select this component when a PNP digital transistor with a 1:1 resistor ratio is required in an SC-70 package. It is appropriate for applications needing 50 V collector-emitter voltage and 100 mA current capacity. Consider its 200 MHz frequency response for high-speed switching needs. Compare with similar RN series parts if different resistor ratios or packages are needed for alternative design constraints.

Part Context

The RN2109ACT belongs to Toshiba's RN series of bias resistor built-in transistors (BRTs). These components integrate bipolar junction transistors with internal bias networks to replace multiple discrete components. The ACT suffix typically denotes a specific packaging variant within the SC-70 family, designed for automated surface-mount assembly processes common in modern electronics manufacturing.

Replacement Considerations

Check for direct equivalents such as the RN2109ACT from other manufacturers like ROHM or ON Semiconductor, ensuring identical pinout and electrical parameters. Verify that substitute parts maintain the same 1:1 resistor ratio and SC-70 footprint. Confirm thermal and voltage ratings match or exceed the original specifications for safe operation.
