RN1908FE,LXHF(CT

Overview

The RN1908FE,LXHF(CT is a dual NPN pre-biased transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two NPN bipolar junction transistors with built-in bias resistors in an ES6 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a transition frequency of 250MHz. The device features a base resistor (R1) of 4.7 kΩ and an emitter resistor (R2) of 4.7 kΩ. It has a maximum power dissipation of 100mW and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrated dual NPN configuration with built-in bias resistors simplifies circuit design by reducing component count.
• Automotive-grade reliability certified under AEC-Q101 standards for robust performance in vehicle applications.
• Compact ES6 surface-mount package facilitates high-density PCB layout and automated assembly.

Applications

• Automotive switching circuits requiring reliable low-power signal control.
• General-purpose digital logic interface and level shifting applications.
• Driver stages for small-signal amplification or relay driving in consumer electronics.

Procurement Notes

Verify the complete part number including the suffix LXHF(CT to ensure correct packaging and RoHS compliance. Confirm that the ES6 package matches your PCB footprint requirements. Check for AEC-Q101 certification if the application demands automotive-grade reliability. Ensure the supplier provides official datasheets to validate the specific resistor ratios and electrical limits before integration into the design.

Selection Notes

Select this component when a dual NPN pre-biased solution is required in a compact surface-mount format. The 4.7kΩ/4.7kΩ resistor ratio suits standard logic interfacing where moderate base drive is sufficient. Consider the 100mA current limit and 50V voltage rating against load requirements. The ES6 package is suitable for space-constrained designs compared to larger through-hole alternatives.

Part Context

This part belongs to the RN19xx series of pre-biased transistor arrays from Toshiba. It shares the same internal transistor structure as the RN1908 but differs in packaging and specific suffix designations. The FE variant typically denotes a specific tape-and-reel or cut-tape packaging option within the LXHF product line, ensuring compatibility with standard SMT manufacturing processes.

Replacement Considerations

Direct pin-compatible substitutes may include other RN1908 variants such as RN1908(TE85L,F) or RN1908,LF(CT, provided the package type matches the design constraints. Verify that alternative parts maintain the same 4.7kΩ/4.7kΩ resistor ratio and meet the 50V/100mA electrical specifications. Automotive applications require checking for equivalent AEC-Q101 qualification status in any replacement component.
