RN2901(T5L,F,T)

Overview

The RN2901(T5L,F,T) 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, designed to simplify circuit design by incorporating built-in bias resistors. The device supports a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA per element. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at 10mA and 5V, with a saturation voltage of 300mV max at 250µA base current and 5mA collector current. The unit features a transition frequency of 200MHz and a maximum power dissipation of 200mW.

Feature Summary

• Integrates complementary NPN and PNP transistors in a compact dual configuration
• Includes built-in bias resistors to reduce external component count and board space
• Optimized for high-speed switching applications with a 200MHz transition frequency

Applications

• Switching circuits requiring complementary logic levels
• Inverter and interface driver circuits
• General-purpose digital signal processing interfaces

Procurement Notes

Verify the specific suffix T5L,F,T against the manufacturer's latest datasheet to confirm packaging type and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the part number with official Toshiba distributors to avoid counterfeit components, as ordering suffixes can indicate variations in reel size or moisture sensitivity handling that do not alter the electrical function.

Selection Notes

Select this component when a compact solution for both NPN and PNP switching is needed without separate discrete parts. The integrated bias resistors eliminate the need for external base resistors, simplifying schematic design. Verify that the 50V voltage rating and 100mA current capacity meet the load requirements. Consider the US6 package dimensions for PCB layout constraints compared to larger transistor packages.

Part Context

This part belongs to the RN29xx series of pre-biased transistor arrays from Toshiba. These devices are engineered to replace multiple discrete transistors and resistors, offering a space-saving alternative for digital logic and switching applications. The RN2901 specifically pairs NPN and PNP types, distinguishing it from single-type arrays like the RN2905 (dual PNP) or RN1904 (dual NPN).

Replacement Considerations

Check for direct equivalents such as the RN2901LF or other variants in the same family. Ensure any substitute maintains the US6 package footprint and identical pinout configuration to guarantee mechanical and electrical compatibility without redesigning the printed circuit board.
