RN1303,LXHF

Overview

The RN1303,LXHF is a single NPN digital transistor manufactured by Toshiba Semiconductor and Storage. It integrates an epitaxial planar silicon NPN transistor with built-in bias resistors in a compact surface-mount package. Key electrical parameters include a collector-emitter voltage (VCEO) of 50V, a continuous collector current (IC) of 100mA, and a maximum power dissipation (Pd) of 100mW. The device features typical input resistors R1 and R2 of 10kΩ each, resulting in a resistor ratio of 1. It operates at a maximum frequency of 250MHz and has a minimum DC current gain (hFE) of 50. The component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Integrates NPN transistor with dual bias resistors to simplify circuit design
• AEC-Q101 qualified for automotive reliability requirements
• Compact SMD packaging suitable for space-constrained layouts

Applications

• Switching circuits
• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and resistance values. Ensure the ordering code matches the required tape-and-reel or cut-tape format. Confirm that the AEC-Q101 qualification meets the specific automotive grade requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a single NPN digital switch with 10kΩ base and emitter resistors is required. It serves as a complementary counterpart to PNP devices like the RN2303 series. Verify that the 50V VCEO and 100mA IC ratings exceed the maximum load conditions of the intended switching application.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which combine bipolar junction transistors with internal biasing networks. The LXHF suffix indicates a specific lead-free and halogen-free packaging variant compliant with environmental standards. It is designed to replace discrete resistor-transistor combinations in modern electronics.

Replacement Considerations

Direct functional substitutes include the RN1302 series if different resistance values are acceptable, provided the package and polarity match. Verify pinout compatibility with alternative manufacturers' single NPN digital transistors before substitution.
