RN4902,LF(CT

Overview

The RN4902,LF(CT is a pre-biased bipolar transistor array containing one NPN and one PNP epitaxial transistor in a US6 surface-mount package. It features integrated bias resistors with a typical value of 10 kΩ each (R1) and a resistor ratio (R1/R2) of 1.0. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of ±50 V for both polarities. Electrical characteristics include a minimum DC current gain (hFE) of 50 at 10 mA and 5 V, and a transition frequency (fT) typically ranging from 200 MHz to 250 MHz. Maximum power dissipation is 200 mW.

Feature Summary

Includes two devices (NPN and PNP) in an ultra super mini type with 6 leads.
Integrated bias resistors reduce the number of external parts required.
Simplifies circuit design and reduces system size and assembly time.

Applications

Switching
Inverter Circuits
Interfacing
Driver Circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official orderable part number list to confirm availability and qualification status. The source document lists RN4902,LF as a general-use option; ensure the CT packaging variant aligns with supply chain requirements. Confirm AEC-Q101 qualification if automotive application is intended, as this depends on the specific base part number configuration.

Selection Notes

Select this component when space-constrained designs require dual complementary switching or inversion functions. The built-in 10 kΩ bias resistors eliminate external resistor placement, reducing board area. Ensure input voltage levels match the specified VI(ON) and VI(off) ranges for reliable saturation and cutoff operation within the 200 mW power dissipation limit.

Part Context

The RN4902 belongs to Toshiba's Silicon PNP/NPN Epitaxial Type series utilizing the PCT Process. Commercial production began in October 1990. The device is designed to replace discrete transistor and resistor combinations, offering a compact solution for interface and driver circuits where minimal footprint and simplified assembly are critical.
