RN1110ACT(TPL3)

Overview

The RN1110ACT(TPL3) is a single NPN Bias Resistor Built-in Transistor (BRT) manufactured by Toshiba Semiconductor and Storage. It integrates an NPN bipolar junction transistor with internal biasing resistors within a compact surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage of 50 V, a continuous collector current rating of 100 mA, and a maximum power dissipation of 150 mW. The device features a DC current gain (hFE) of at least 120 when tested at 1 mA collector current and 5 V collector-emitter voltage. It operates reliably across a temperature range from -40°C to +150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates NPN transistor with built-in bias resistors to reduce external component count and PCB space.
• Automotive-grade reliability certified under the AEC-Q101 standard for harsh environment operation.
• High thermal stability supports continuous operation at junction temperatures up to 150°C.

Applications

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

Procurement Notes

Verify the specific suffix TPL3 against the official Toshiba datasheet to confirm pinout compatibility and tape-and-reel specifications. Confirm that the AEC-Q101 qualification status remains active for this specific marking code before finalizing procurement plans.

Selection Notes

Select this component when a single NPN BRT with 50V rating and 100mA capacity is required for automotive applications. Ensure the integrated resistor values match the design requirements, as they are fixed within the package. Compare thermal performance against alternative packages if high power density is critical.
