RN4902FE,LXHF(CT

Overview

The RN4902FE,LXHF(CT is a pre-biased digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates one NPN and one PNP bipolar junction transistor within a single US-6 surface-mount package. The device features built-in bias resistors to simplify circuit design and reduce component count. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a power dissipation (Pd) of 200 mW. The typical input resistance for both transistors is 10 kΩ. The unit operates at a maximum frequency of 250 MHz and supports a maximum operating temperature of +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in bias resistors in a compact SMD package
• Reduces printed circuit board space and assembly costs by replacing discrete components
• Designed for high-speed switching applications with a transition frequency up to 250 MHz

Applications

• Switching circuits for automotive and industrial control systems
• Inverter and interface circuits in consumer electronics
• Driver circuits for low-power loads requiring compact form factors

Procurement Notes

Verify the specific suffix LXHF(CT) against the manufacturer's latest datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering quantity matches the available reel or cut-tape options provided by authorized distributors. Cross-reference the part number with official Toshiba Semiconductor and Storage catalogs to avoid counterfeit components.

Selection Notes

Select this component when a dual-channel solution with both NPN and PNP outputs is required in a minimal footprint. The 10 kΩ internal resistor values are suitable for standard logic level interfacing. Consider the 200 mW power dissipation limit during thermal analysis for dense PCB layouts. Verify that the 50 V voltage rating exceeds the maximum circuit operating voltage.

Part Context

This part belongs to the Toshiba RN49xx series of pre-biased digital transistors. These devices utilize an epitaxial planar process to achieve high reliability and consistent performance. The US-6 package is a standard small-outline format designed for automated surface-mount assembly processes common in modern electronics manufacturing.

Replacement Considerations

Check for direct equivalents such as the RN4902FE(TPL3,F) or other RN4902 variants from Toshiba. Verify pin compatibility and electrical parameters before substituting with parts from other manufacturers.
