RN1411,LXHF

Overview

The RN1411,LXHF is a PNP digital transistor manufactured by Toshiba Semiconductor and Storage, designed for automotive applications with AEC-Q101 qualification. It integrates a single PNP bipolar junction transistor with internal bias resistors in an SSM-3 (SOT-416) surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (Pd) of 100 mW. The device features a typical base resistor (R1) of 22 kOhms and an emitter-base voltage (VEBO) of 10 V. It operates at a maximum frequency of 200 MHz and supports a maximum operating temperature of +150°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for enhanced durability in vehicle environments.
• Integrated bias resistors simplify circuit design by reducing component count and board space requirements.
• High thermal stability supports operation at elevated temperatures up to 150°C.

Applications

• Switching circuits in automotive electronic control units (ECUs).
• Interface connections between microcontrollers and peripheral devices.
• Driver circuits for low-power loads in automotive systems.

Procurement Notes

Verify the specific suffix LXHF(CT) against the official Toshiba datasheet to confirm packaging type and reel specifications. Ensure the component meets AEC-Q101 requirements for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest product documentation before integration into production.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for automotive switching applications. The 22 kOhm input resistance suits standard logic interface levels. Consider the SSM-3 package size for space-constrained designs. Verify that the -50 V rating and -100 mA current capacity align with the load requirements of the target circuit.

Part Context

The RN1411 belongs to Toshiba's RN series of pre-biased transistors, which are optimized for automotive use. This series combines NPN and PNP variants with various resistor ratios to provide flexible solutions for digital switching. The LXHF suffix typically denotes automotive-grade qualification and specific packaging configurations within Toshiba's portfolio.

Replacement Considerations

Direct substitutes may include other PNP digital transistors with similar VCEO, IC, and R1 values in SSM-3 packages. Verify pinout compatibility and electrical characteristics such as hFE and saturation voltage before substitution. Check if alternative parts meet AEC-Q101 requirements if used in automotive contexts.
