RN2905FE,LXHF(CT

Overview

The RN2905FE,LXHF(CT is a dual PNP digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two PNP transistors with built-in bias resistors into 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 R1=4.7 kOhm and R2=47 kOhm, yielding a typical resistance ratio of approximately 0.0468. The component has a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, with a power dissipation rating of 200 mW. It is qualified under AEC-Q101 for automotive applications and operates up to a maximum junction temperature of +150°C.

Procurement Notes

Verify the specific suffix FE against the manufacturer's official documentation to confirm pinout symmetry or variant differences, as ordering codes can indicate distinct electrical or mechanical configurations. Ensure the supplier provides valid traceability documents confirming AEC-Q101 qualification status. Cross-reference the Mouser part number 757-RN2905FE,LXHF(CT with the original Toshiba datasheet to validate the exact resistor ratios and package dimensions before finalizing procurement orders.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required for space-constrained designs. The US6 package offers a small footprint suitable for high-density PCB layouts. Verify that the 4.7 kOhm input resistor and 47 kOhm emitter resistor values align with the target logic levels and drive requirements. Ensure the system voltage does not exceed the 50 V collector-emitter rating and that thermal management supports the 200 mW power dissipation limit.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine bipolar junction transistors with internal resistors to simplify digital switching applications. The RN2905 variant specifically utilizes a PNP x 2 configuration. The LXHF suffix typically denotes a lead-free, halogen-free packaging specification compliant with environmental directives. These devices are designed to replace multiple discrete components, thereby reducing assembly time and board space.

Replacement Considerations

Publicly confirmed substitute part numbers include RN2905AFS, RN2905FE, and RN2905FS from Toshiba Semiconductor. When replacing, verify that the alternative package type matches the existing footprint and that the internal resistor values remain identical to maintain circuit timing and bias stability.
