RN4908FE,LXHF(CT

Overview

The RN4908FE,LXHF(CT is a pre-biased digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates one NPN and one PNP epitaxial transistor within a single US6 (SOT-363) surface-mount package. The device features built-in bias resistors to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a total power dissipation of 200mW. The unit operates with transition frequencies up to 200MHz for the NPN and 250MHz for the PNP element.

Feature Summary

• Integrates complementary NPN and PNP transistors into a compact six-lead package
• Includes internal bias resistors to reduce external component count
• Designed for high-speed switching applications with specified transition frequencies

Applications

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

Procurement Notes

Verify the specific suffix LXHF(CT against official Toshiba documentation to confirm tape-and-reel packaging and automotive-grade qualification status. Ensure the ordering code matches the required RoHS compliance and moisture sensitivity level for your assembly process. Cross-reference the manufacturer part number with distributor listings to confirm current availability and lead times prior to procurement.

Selection Notes

Select this component when a dual-channel solution requiring both NPN and PNP logic inversion or buffering is needed in a minimal footprint. The integrated bias resistors eliminate the need for external base resistors, simplifying layout. Verify that the 50V breakdown voltage and 100mA current rating meet the specific load requirements of the target application interface.

Part Context

This part belongs to the RN49xx series of pre-biased transistors from Toshiba. These devices are designed to replace multiple discrete components, including transistors and resistors, thereby reducing printed circuit board area and manufacturing costs. The US6 package is an extreme-super-mini form factor suitable for dense consumer and industrial electronics.
