RN1417,LXHF

Overview

The RN1417,LXHF is a single NPN digital transistor manufactured by Toshiba Semiconductor and Storage. It integrates an epitaxial planar silicon BJT with built-in bias resistors in a compact S-Mini (USM-3) surface-mount package. Key electrical parameters include a collector-emitter breakdown voltage of 50 V, a continuous collector current of 100 mA, and a maximum power dissipation of 200 mW. The device features typical internal resistances of R1 = 10 kOhms and R2 = 10 kOhms, resulting in a resistor ratio of 1. It operates at a transition frequency of 250 MHz with a minimum DC current gain of 50 and supports a maximum operating temperature of +150°C.

Feature Summary

• Integrates NPN bipolar junction transistor with dual bias resistors for simplified circuit design
• Optimized for high-speed switching applications with a 250 MHz transition frequency
• Automotive-grade reliability certified under AEC-Q101 standards
• Compact USM-3 surface-mount packaging facilitates space-constrained layouts

Applications

• Automotive electronic control units requiring AEC-Q101 qualified components
• Logic level shifting and interface circuits between microcontrollers and peripherals
• Driver circuits for low-power loads and signal inversion tasks

Procurement Notes

Verify the specific suffix LXHF to confirm the reel packaging format and lead-free status. Confirm that the component meets RoHS directives if required by your manufacturing process. Ensure the supplier provides traceability documentation consistent with automotive quality standards. Check for any specific handling instructions related to the small outline package during assembly.

Selection Notes

Select this component when a single NPN digital transistor with equal bias resistors is needed. The 50 V rating suits general-purpose logic interfacing. Consider the 200 mW power dissipation limit for thermal management. Compare against other RN series variants if different resistor ratios or higher current capabilities are required for the specific application load.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine BJTs with internal resistors to reduce board space and assembly costs. The LXHF suffix typically denotes a specific tape-and-reel packaging configuration intended for automated surface-mount placement processes.

Replacement Considerations

Direct substitutes within the same family include RN1417,LF. Verify pin compatibility and electrical ratings before replacing. Cross-manufacturer equivalents require careful validation of resistor values and hFE characteristics.
