RN4984,LXHF(CT

Overview

The RN4984,LXHF(CT is a dual digital transistor from Toshiba Semiconductor and Storage, configured as a 2-in-1 point-symmetrical NPN and PNP array. It integrates bias resistors to simplify circuit design. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Internal base resistors are typically 10 kOhms for both transistors. The unit operates with a maximum power dissipation of 200 mW and supports a transition frequency up to 250 MHz. It is housed in an SMD US-6 package and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Combines NPN and PNP transistors with integrated bias resistors in a single compact surface-mount package
• Point-symmetrical internal configuration simplifies PCB layout and component placement
• Qualified for automotive applications under the AEC-Q101 standard

Applications

• Automotive logic switching circuits requiring AEC-Q101 compliance
• General-purpose digital buffering and level shifting
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix LXHF against the manufacturer's latest datasheet to confirm lead-free status and tape-and-reel specifications. Ensure the ordering code matches the required packaging format. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when a symmetrical NPN/PNP pair with fixed bias resistors is required for space-constrained designs. Verify that the 10 kOhm internal resistance values align with the driving source capabilities. Confirm that the 50 V rating and 100 mA current limits exceed the application's peak operational requirements.

Part Context

This part belongs to the Toshiba RN49xx series of pre-biased digital transistors. These components replace discrete resistor-transistor networks, reducing board space and assembly costs. The LXHF variant specifically denotes automotive-grade reliability and environmental compliance within the broader RN4984 family.

Replacement Considerations

Check for direct equivalents such as the RN4984FE,LXHF(CT or other RN4984 variants with different suffixes. Verify pin compatibility and electrical parameters before substitution. Consult Toshiba documentation for approved alternative part numbers within the same product line.
