RN2110ACT(TPL3)

Overview

The RN2110ACT(TPL3) is a PNP digital transistor manufactured by Toshiba Semiconductor and Storage, featuring built-in bias resistors to simplify circuit design. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes an internal base resistor (R1) of 47 kΩ and an emitter resistor (R2) of 47 kΩ, providing a 1:1 resistance ratio. Packaged in the SOT-323 (SC-70) surface-mount format, it supports a maximum power dissipation of 100 mW and functions within a temperature range of -55°C to +150°C.

Feature Summary

• Integrated dual bias resistors eliminate external component requirements for base drive circuits.
• High-density SC-70 package minimizes printed circuit board area consumption.
• Automotive-grade qualification ensures reliability under varying thermal conditions.

Applications

• Switching applications in automotive electronic control units
• Interface circuits between microcontrollers and peripheral devices
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix TPL3 against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure compliance with RoHS directives and AEC-Q101 automotive standards if required for the target application environment. Cross-reference the full part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a PNP configuration with equal bias resistors is required for logic-level interfacing. The 47kΩ resistor values are suitable for standard TTL and CMOS logic outputs. Consider the SC-70 footprint constraints and thermal management capabilities relative to the expected power dissipation in the final assembly.

Part Context

This part belongs to Toshiba's RN series of bias resistor-built-in transistors, designed to replace discrete BJT and resistor combinations. The RN2110ACT variant specifically denotes the PNP polarity with defined resistance ratios. The ACT suffix typically indicates specific testing or grading criteria within the product line.

Replacement Considerations

Direct substitutes include other PNP digital transistors with 50V rating, 100mA current, and 1:1 bias resistor ratios in SC-70 packages. Verify pinout compatibility and hFE characteristics before substitution. Check for equivalent automotive qualification status if used in vehicle systems.
