RN2904,LXHF(CT

Overview

The RN2904,LXHF(CT is a pre-biased digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two PNP bipolar junction transistors with built-in bias resistors in a compact surface-mount package. The device features a collector-emitter breakdown voltage of 50V and a maximum continuous collector current of 100mA. Each transistor includes a base resistor (R1) and an emitter resistor (R2), both specified at 47 kΩ. The unit operates within a transition frequency of 200MHz and has a maximum power dissipation of 100mW. It is housed in the ES6 supplier device package, corresponding to the SOT-563 or SOT-666 physical footprint.

Feature Summary

• Integrates dual PNP transistors with fixed internal bias resistors to simplify circuit design
• Optimized for high-speed switching applications with a 200MHz transition frequency
• Compact surface-mount packaging reduces board space requirements

Applications

• Switching circuits in automotive electronic control units
• Interface connection drivers for logic level translation
• Inverter driver stages requiring compact pre-biased solutions

Procurement Notes

Verify the specific ordering suffix LXHF(CT against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the ES6 package designation matches the intended PCB land pattern. Confirm AEC-Q101 qualification if the application requires automotive grade reliability standards before finalizing procurement.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required. The 47kΩ resistor values are suitable for standard logic interface driving. Consider the 100mA current limit and 50V voltage rating during circuit design. Verify that the thermal dissipation capabilities of the ES6 package meet the system's power budget under worst-case operating conditions.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine BJT arrays with internal resistors. The RN2904 variant specifically provides two PNP devices. The LXHF(CT) suffix indicates the tape and reel packaging format and specific manufacturing lot characteristics defined by Toshiba for automated assembly processes.

Replacement Considerations

Direct substitutes include other Toshiba parts in the RN290x series with identical resistor ratios and package types. Cross-manufacturer replacements require verification of hFE gain curves, saturation voltages, and pinout alignment to ensure functional equivalence in the existing circuit layout.
