RN4901(T5L,F,T)

Overview

The RN4901(T5L,F,T) is a pre-biased digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates one NPN and one PNP epitaxial transistor within a single US6 surface-mount package, featuring built-in bias resistors with a ratio of 1:1 (R1=4.7kΩ, R2=4.7kΩ). Key electrical specifications include a maximum collector current of 100mA, a collector-emitter voltage rating of 50V, and a transition frequency of 200MHz for the NPN and 250MHz for the PNP element. The device supports a maximum power dissipation of 200mW and operates within a temperature range up to 150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors with fixed internal bias resistors in a compact six-lead package
• Simplifies circuit design by reducing component count and manufacturing processes through integrated biasing
• Utilizes Silicon PCT process technology for reliable switching performance

Applications

• Switching circuits requiring compact dual-transistor solutions
• Inverter circuits for signal inversion applications
• Interface circuits for logic level translation
• Driver circuits for low-power load control

Procurement Notes

Verify the specific suffix T5L,F,T against official Toshiba documentation to confirm tape-and-reel packaging and lead-free status. Confirm availability as standard RN4901 variants may be discontinued while LXHF(CT versions remain active. Ensure compatibility with existing PCB footprints for the US6 package before procurement.

Selection Notes

Select this component when a combined NPN/PNP pair with matched 4.7kΩ bias resistors is required. The US6 package offers space savings compared to discrete components. Verify that the 50V voltage rating and 100mA current limits meet the target application requirements. Consider the AEC-Q101 qualification if automotive reliability standards are necessary for the deployment environment.

Part Context

The RN4901 belongs to Toshiba's series of pre-biased digital transistors designed to replace multiple discrete components. It is part of the broader RN family, which includes variations like the RN1904 (dual NPN) and RN2001 (dual PNP). These devices are engineered to streamline board layout and reduce assembly costs in consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitutes include the RN4901,LXHF(CT variant from Toshiba Semiconductor and Storage. This version maintains identical electrical characteristics but may differ in packaging configuration or compliance certifications such as AEC-Q101 automotive qualification.
