RN1309,LXHF

Overview

The RN1309,LXHF is an automotive-grade single NPN digital transistor certified to AEC-Q101 standards. It integrates a built-in bias resistor network with typical values of R1=47kΩ and R2=47kΩ, resulting in a resistance ratio of 1. The device operates within a collector-emitter voltage (VCEO) of 50V and supports a continuous collector current of 100mA. Key electrical specifications include a minimum DC current gain (hFE) of 30 and a maximum operating frequency of 250MHz. Power dissipation is rated at 100mW, with a maximum junction temperature of +150°C. It is housed in the USM-3 package.

Procurement Notes

Verify that the ordering part number explicitly includes the LXHF suffix to ensure compliance with automotive grade requirements and specific packaging configurations. Confirm AEC-Q101 certification status through official Toshiba documentation prior to integration into safety-critical automotive designs. Ensure supply chain sources provide valid traceability data consistent with original manufacturer specifications.

Selection Notes

Select this component when an NPN digital transistor with integrated biasing is required for automotive environments. The 47kΩ input resistance configuration suits standard logic interface applications. Consider the USM-3 package dimensions for PCB layout constraints. Verify that the 50V VCEO rating meets the specific voltage requirements of the target application circuit.

Part Context

This component belongs to Toshiba's RN series of pre-biased transistors, designed to replace discrete resistor-transistor combinations. The LXHF suffix denotes specific automotive-grade manufacturing and packaging standards. It serves as a compact solution for switching and amplification tasks where space efficiency and reliability are critical factors in modern electronic assemblies.

Replacement Considerations

Consult official Toshiba cross-reference documents for verified substitute part numbers. Do not assume functional equivalence based on generic specifications alone. Verify pinout compatibility and electrical parameter margins before implementing any alternative components in existing designs.
