RN2905FE,LF(CT

Overview

The RN2905FE,LF(CT is a dual digital transistor manufactured by Toshiba Semiconductor and Storage. It integrates two PNP transistors with built-in bias resistors in a single US6 surface-mount package. The device features a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Internal resistor values are typically R1=2.2 kOhms and R2=47 kOhms. It operates within a temperature range up to +150°C and dissipates 200 mW of power. The component is AEC-Q101 qualified for automotive applications.

Feature Summary

• Integrates two PNP transistors with internal bias resistors into a compact six-lead package
• Simplifies circuit design by reducing the quantity of external components required
• Qualified for automotive use under AEC-Q101 standards

Applications

• Switching circuits
• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific suffix FE against the manufacturer's official documentation to confirm pinout and electrical characteristics match the target design requirements. Ensure the LF designation aligns with RoHS compliance needs. Confirm availability through authorized distributors as supply levels fluctuate. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Selection Notes

Select this component when a dual PNP digital transistor configuration is required for space-constrained designs. The integrated bias network eliminates the need for external base resistors, simplifying layout. Verify that the -50 V rating and -100 mA current capacity meet the load requirements. Consider the US6 package dimensions for PCB footprint constraints compared to standard discrete transistors.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine bipolar junction transistors with internal resistor networks. The RN2905 variant specifically provides a complementary pair to the RN190x NPN series, allowing for push-pull or differential configurations in a single package. This integration supports miniaturization in portable and automotive electronics.

Replacement Considerations

Publicly confirmed substitutes include RN2905,LXHF(CT and RN2905AFS from Toshiba Semiconductor. These alternatives share similar electrical characteristics and package types. Verify pin compatibility and thermal performance before substitution.
