RN4984(T5L,F,T)

Overview

The RN4984(T5L,F,T) is a pre-biased bipolar junction transistor (BJT) array manufactured by Toshiba Semiconductor and Storage. It integrates one NPN and one PNP transistor in a single surface-mount package with built-in bias resistors. The device features a collector-emitter breakdown voltage of 50V and a continuous collector current rating of 100mA. It operates within a transition frequency range of 200MHz to 250MHz, depending on the specific transistor configuration. The maximum power dissipation is specified at 200mW. The component utilizes the SOT-363 (US6/SC-88) package, measuring 2.0mm x 2.1mm x 0.9mm, and is designed for general-purpose switching applications.

Feature Summary

• Integrates complementary NPN and PNP transistors with internal bias resistors in a point-symmetrical 2-in-1 configuration.
• Utilizes a compact SOT-363 surface-mount package suitable for high-density PCB layouts.
• Qualified under AEC-Q101 standards for automotive reliability requirements.

Applications

• General-purpose digital switching circuits
• Automotive electronic control units requiring AEC-Q101 qualified components
• Interface driver stages in consumer electronics

Procurement Notes

Verify the specific suffix and tape-and-reel specifications when ordering. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the selected packaging matches the automated assembly equipment requirements. Check for any recent lifecycle notifications regarding availability or obsolescence before finalizing procurement plans.

Selection Notes

Select this component for designs requiring matched NPN/PNP pairs with integrated base resistors to reduce external component count. The 50V rating and 100mA current capacity suit low-power logic interface tasks. Consider the 200mW power dissipation limit when determining thermal management needs in enclosed spaces. The SOT-363 footprint requires appropriate land pattern design for reliable soldering.

Part Context

This part belongs to Toshiba's RN49xx series of digital transistors, which are pre-biased BJT arrays. The RN4984 specifically denotes the variant with defined internal resistor values for both NPN and PNP elements. It is distinct from other series members like RN4981 or RN4982 based on its specific resistance ratios and package type. The series is widely used in portable devices and automotive systems due to its small form factor.

Replacement Considerations

Direct substitutes include other Toshiba RN49xx series parts with identical pinouts and electrical characteristics. Verify that alternative manufacturers' equivalents match the 50V Vceo, 100mA Ic, and SOT-363 package dimensions. Ensure the replacement maintains AEC-Q101 qualification if used in automotive applications.
