RN4908,LXHF(CT

Overview

The RN4908,LXHF(CT is a pre-biased digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates one PNP and one NPN epitaxial transistor within a US6 (SOT-363) surface-mount package. The device features built-in bias resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of -50V, a continuous collector current of 100mA, and a power dissipation rating of 200mW. The typical base resistor (R1) is 10 kΩ and the emitter resistor (R2) is 47 kΩ. The component supports a maximum operating temperature of +150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates complementary PNP and NPN transistors with built-in bias resistors in a single compact package
• Reduces printed circuit board space requirements and simplifies assembly processes
• Designed for high-speed switching applications with transition frequencies up to 200MHz

Applications

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

Procurement Notes

Verify the specific suffix LXHF(CT against the official Toshiba datasheet to confirm pinout compatibility and internal resistor values. Ensure the ordering code matches the required packaging format, such as tape and reel or cut tape, as specified by the distributor. Confirm RoHS compliance status and automotive grade certification if the application requires AEC-Q101 qualification.

Selection Notes

Select this component when a compact solution for simultaneous PNP and NPN switching is required. The fixed 10kΩ/47kΩ resistor ratio suits standard logic interface levels. Verify that the 100mA collector current and 200mW power dissipation meet the thermal and load requirements of the target application before finalizing the design.

Part Context

This part belongs to the RN49xx series of pre-biased transistors from Toshiba. These devices utilize the PCT process for improved performance. The US6 package is an ultra-super mini type designed to minimize footprint in portable electronics. The LXHF suffix typically denotes specific packaging or material specifications within the manufacturer's catalog.

Replacement Considerations

Direct substitutes may include other RN4908 variants with different suffixes, such as RN4908,LF or RN4908FE, provided the package and electrical characteristics remain identical. Cross-referencing with other manufacturers' dual pre-biased transistor arrays requires verifying the resistor ratios and pin configurations.
