RN1416,LXHF

Overview

The RN1416,LXHF is a single NPN digital transistor manufactured by Toshiba Semiconductor and Storage. It integrates bias resistors within a compact S-Mini (TO-236-3, SC-59, SOT-23-3) surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. Internal resistor values are specified as R1 = 4.7 kOhms and R2 = 10 kOhms. Key electrical parameters include a DC current gain (hFE) of at least 50 at 10 mA and 5 V, a saturation voltage of 300 mV max at 250 µA base current and 5 mA collector current, and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count.
• Optimized for high-speed switching applications with a 250 MHz transition frequency.
• Complies with AEC-Q101 automotive qualification standards for reliability.

Applications

• Automotive switch circuits
• Inverter driver circuits
• Interface connection logic

Procurement Notes

Verify the LXHF suffix indicates specific automotive-grade screening and packaging configuration distinct from standard commercial variants. Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the required tape-and-reel quantity specifications for automated assembly lines.

Selection Notes

Select this component when a single NPN pre-biased transistor with 4.7 kOhm input resistance is required in an SOT-23 form factor. Verify that the 50 V collector-emitter voltage rating meets the system's maximum operating voltage. Check that the 200 mW power dissipation capability is sufficient for the intended thermal environment.

Part Context

This part belongs to Toshiba's RN series of built-in bias resistor transistors designed for automotive and industrial use. The LXHF suffix typically denotes automotive-grade qualification (AEC-Q101) and specific reel packaging. It serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs.

Replacement Considerations

Direct substitutes must match the NPN polarity, 50 V rating, 100 mA current, and identical internal resistor values (R1=4.7k, R2=10k). Verify pinout compatibility with TO-236-3/SOT-23-3 packages. Cross-reference AEC-Q101 certification if automotive reliability is mandatory.
