RN2418,LXHF

Overview

The RN2418,LXHF is a PNP pre-biased transistor manufactured by Toshiba Semiconductor and Storage. It integrates a single NPN bipolar junction transistor with built-in bias resistors in an S-Mini (SC-59) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a transition frequency of 200MHz. The device features a DC current gain of at least 50 at 10mA and 5V, with a maximum saturation voltage of 300mV. Internal resistor values are typically 47kΩ for the base (R1) and 10kΩ for the emitter (R2).

Feature Summary

• Integrates a PNP BJT with dual internal bias resistors to simplify circuit design.
• Provides high-speed switching capabilities with a 200MHz transition frequency.
• Offers low saturation voltage for efficient power dissipation during operation.

Applications

• Switching circuits requiring compact form factors.
• Interface circuits between logic gates and loads.
• Driver circuits for small-signal applications.

Procurement Notes

Verify the specific suffix 'LXHF' against official Toshiba documentation to confirm it denotes the standard RoHS-compliant lead-free variant consistent with the 'LF' designation found in general product listings. Ensure the ordering code matches the required tape-and-reel or cut-tape packaging format for your assembly line. Confirm availability through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The SC-59 package suits applications needing minimal PCB area. Verify that the 50V voltage rating and 100mA current capacity meet the load requirements. Consider the 47kΩ/10kΩ resistor ratio for appropriate base drive characteristics in the target application.

Part Context

The RN2418 belongs to Toshiba's digital transistor series, which combines transistors with bias resistors. This family includes various configurations such as NPN and PNP types with different resistor ratios. The RN2418 specifically addresses the need for simplified driver circuits in consumer electronics and industrial control systems where board space is limited.

Replacement Considerations

Check for direct substitutes like the RN2418,LF or RN2418LFDKR from Toshiba. Cross-reference pinouts and electrical parameters with other manufacturers' PNP pre-biased transistors in the SC-59 package before substitution.
