RN1907FE,LXHF(CT

Overview

The RN1907FE,LXHF(CT is an automotive-grade, AEC-Q qualified dual NPN pre-biased digital transistor housed in a compact SOT-563 (ES-6) surface-mount package. It integrates two point-symmetrical NPN transistors with internal biasing resistors, featuring a typical base series resistor of 10 kΩ and a base-emitter resistor of 47 kΩ. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 100 mW. It offers a high cutoff frequency of 250 MHz and a minimum DC current gain of 80 at 10 mA and 5 V, operating reliably up to a maximum junction temperature of +150°C.

Feature Summary

• Integrates two point-symmetrical NPN transistors with built-in biasing resistors for simplified circuit design
• Automotive-grade construction compliant with AEC-Q standards for enhanced reliability
• High-speed switching capability with a maximum cutoff frequency of 250 MHz
• Compact SOT-563 surface-mount packaging suitable for space-constrained applications

Applications

• Automotive electronic control units requiring robust switching components
• General-purpose logic level translation and interface circuits
• Driver stages for relays, solenoids, or small loads in industrial systems

Procurement Notes

Verify the specific ordering suffix against official Toshiba documentation to ensure correct tape-and-reel specifications and automotive qualification status. Confirm that the ES-6 package variant matches your PCB footprint requirements. Cross-reference the AEC-Q certification details with your quality management system standards before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required for automotive or high-reliability applications. Ensure the 50V breakdown voltage and 100mA current limits align with your load requirements. Consider the 10kΩ input resistance for drive current calculations and verify thermal dissipation capabilities within the 100mW limit under your specific operating conditions.

Part Context

This part belongs to Toshiba's RN series of pre-biased digital transistors, designed to replace discrete resistor-transistor networks. The RN1907FE specifically utilizes a dual NPN topology within the SOT-563 package, offering a symmetrical layout that simplifies board layout compared to single-transistor variants. It complements other models in the family by providing matched characteristics for differential or push-pull configurations.

Replacement Considerations

Direct substitutes include the RN1906FE,LXHF(CT for similar NPN dual configurations with different resistor values, or the RN2907FE,LXHF(CT if PNP polarity is acceptable. Verify pinout compatibility and electrical parameter margins before swapping between these related Toshiba part numbers.
