RN1909,LXHF(CT

Overview

The RN1909,LXHF(CT is a dual NPN pre-biased transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two NPN transistors with built-in bias resistors in an ES6 (SOT-563) surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of 50V, a continuous collector current (IC) of 100mA, and a transition frequency (fT) of 250MHz. The device features a base resistor (R1) of 4.7kΩ and an emitter resistor (R2) of 4.7kΩ. It has a maximum power dissipation of 100mW and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Dual NPN configuration with integrated bias resistors for simplified circuit design
• Automotive-grade reliability certified under AEC-Q101 standards
• High-speed switching capability with a 250MHz transition frequency
• Compact SMD packaging suitable for space-constrained applications

Applications

• Automotive interface circuits requiring signal level shifting
• Driver circuits for low-power loads in vehicle electronics
• Switching applications in automotive control modules
• Inverter gate drive circuits within automotive systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and resistance values. Confirm AEC-Q101 compliance requirements for your target application. Check for alternative suffixes that may indicate different thermal or mechanical characteristics. Ensure compatibility with your PCB footprint for the ES6 package. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when a dual NPN digital transistor with equal bias resistors is required. The 4.7kΩ resistor values provide a standard input impedance for many logic families. Consider the 100mA current limit and 50V voltage rating for load compatibility. The ES6 package offers a compact solution compared to discrete components. Verify thermal management needs given the 100mW power dissipation limit.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors designed for automotive and industrial applications. The RN19xx series specifically denotes dual NPN configurations. The LXHF suffix typically indicates lead-free and halogen-free compliance. These devices replace multiple discrete components, reducing board space and assembly costs.

Replacement Considerations

Direct substitutes must match the dual NPN topology, 50V VCEO, 100mA IC, and ES6 package. Verify equivalent bias resistor values (4.7kΩ/4.7kΩ) and hFE characteristics. Check if alternative manufacturers offer AEC-Q101 qualified parts with identical pinouts and electrical parameters.
