RN1306,LXHF

Overview

The RN1306,LXHF is a single NPN digital transistor from Toshiba Semiconductor and Storage, designed for automotive applications under the AEC-Q101 qualification standard. It integrates an NPN bipolar junction transistor with internal bias resistors in a compact SMD package. Key electrical parameters 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 10 kOhms and an emitter resistor (R2) of 10 kOhms, resulting in a resistor ratio of 1. It operates at a maximum frequency of 250 MHz with a minimum DC current gain (hFE) of 50.

Feature Summary

• Automotive-grade reliability certified to AEC-Q101 standards for enhanced durability in vehicle environments.
• Integrated bias resistors simplify circuit design by reducing component count and board space requirements.
• High-speed switching capability supported by a transition frequency of up to 250 MHz.

Applications

• Switching circuits in automotive electronic control units.
• Inverter driver circuits for motor control applications.
• Interface connection buffers between logic levels.
• General-purpose driver circuits requiring compact form factors.

Procurement Notes

Verify the specific suffix LXHF against the official Toshiba datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with AEC-Q101 requirements if the application mandates automotive-grade components. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability. Check for any recent product change notices regarding marking or packaging updates.

Selection Notes

Select this component when a single NPN digital transistor with integrated 10k/10k bias resistors is required for 50V applications. The 100 mA current rating suits low-power switching tasks. Consider the SC-70 (SOT-323) package constraints for PCB layout. Verify that the 250 MHz frequency response meets the signal speed requirements of the target circuit design.

Part Context

This part belongs to Toshiba's RN series of built-in bias resistor transistors, which are optimized for automotive use. The RN1306 variant specifically provides an NPN configuration with equal base and emitter resistance values. It is distinct from other RN series parts that may offer different resistor ratios, polarities, or higher current ratings.

Replacement Considerations

Direct substitutes must match the NPN polarity, 50V VCEO, 100mA IC, and 10k/10k resistor ratio. Verify package compatibility with SC-70/SOT-323 dimensions. Automotive replacements should also hold AEC-Q101 certification. Consult Toshiba's official substitution guide for validated equivalent part numbers.
