RN4983FE,LXHF(CT

Overview

The RN4983FE,LXHF(CT is a dual pre-biased bipolar junction transistor (BJT) array manufactured by Toshiba Semiconductor and Storage. It integrates one NPN and one PNP transistor within a single US6 surface-mount package, featuring built-in bias resistors to simplify circuit design. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Key electrical parameters include a minimum DC current gain (hFE) of 50 at 10mA and 5V, with a saturation voltage of 300mV max at 250µA base current and 5mA collector current. The unit dissipates up to 200mW of power and operates at transition frequencies up to 250MHz. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Reduces component count and simplifies layout for interface and driver circuits

Applications

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

Procurement Notes

Verify the specific suffix LXHF against the official Toshiba datasheet to confirm pinout symmetry and resistor values. Ensure the ordering code matches the required packaging format, such as cut tape or reel, as distribution variants may differ. Confirm RoHS compliance status directly from the manufacturer's documentation prior to finalizing procurement orders.

Selection Notes

Select this component when a symmetrical NPN/PNP pair 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 50V voltage rating and 100mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the RN49xx series of digital transistors from Toshiba, designed to replace discrete resistor-transistor networks. The FE suffix typically denotes specific internal resistor configurations, while LXHF indicates the automotive-grade variant and packaging type. It serves as a direct replacement for standard pre-biased arrays in modern electronic systems requiring miniaturization.

Replacement Considerations

Check for equivalent parts like RN4982FE or RN4984FE if different resistor ratios are acceptable. Verify pin compatibility with existing footprints before substituting. Ensure any alternative maintains AEC-Q101 qualification if used in automotive environments.
