RN2909,LXHF(CT

Overview

The RN2909,LXHF(CT is a PNP digital transistor from Toshiba Semiconductor and Storage, designed for automotive applications with AEC-Q101 qualification. It integrates two PNP transistors in a single US-6 (SOT-363) surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features typical input resistors of 47 kOhms and 22 kOhms, resulting in a resistor ratio of 2.14. It offers a minimum DC current gain (hFE) of 70 and supports operating frequencies up to 200 MHz or 250 MHz. Power dissipation is rated at 200 mW, with a maximum operating temperature of +150°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for enhanced durability in vehicle environments.
• Dual PNP configuration within a compact SMD package simplifies circuit design by reducing component count.
• Integrated bias resistors eliminate external base drive components, facilitating direct interface with logic circuits.

Applications

• Switching circuits in automotive electronic control units
• Inverter circuit driver stages
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix LXHF(CT) against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the AEC-Q101 qualification status meets the specific requirements of the target automotive application before finalizing procurement decisions.

Selection Notes

Select this component when a dual PNP digital transistor with integrated bias resistors is required for space-constrained designs. Consider the -50V voltage rating and -100mA current capacity to ensure adequate headroom for the intended load. Verify that the US-6 package footprint aligns with the PCB layout constraints.

Part Context

This part belongs to Toshiba's RN series of built-in bias resistor transistors, which are optimized for automotive use. The RN2909 specifically provides a dual PNP solution, contrasting with single-transistor variants like the RN2309 or complementary pairs like the RN4903. It serves as a specialized component within the broader discrete semiconductor portfolio for power management and signal switching.
