RN2911,LXHF(CT

Overview

The RN2911,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 US-6 (SOT-363) surface-mount package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device features built-in bias resistors with typical values of R1=47 kOhms and R2=22 kOhms per transistor, resulting in a resistor ratio of approximately 2.14. Minimum DC current gain (hFE) is specified at 70. Power dissipation is rated at 200 mW, with a maximum operating temperature of +150°C and a cutoff frequency up to 250 MHz.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Dual PNP configuration with integrated bias resistors simplifies circuit design
• High switching speed capability suitable for high-frequency applications

Applications

• Switching circuits in automotive electronic control units
• Inverter circuit interfaces
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix LXHF(CT) against the manufacturer's official datasheet to confirm pinout and internal resistor configurations. Ensure that the US-6 package dimensions match the target PCB footprint. Confirm AEC-Q101 compliance requirements are met for the intended automotive application environment before finalizing component selection.

Selection Notes

Select this component when a dual PNP digital transistor with moderate input resistance is required. The -50V rating suits low-voltage automotive systems. Compare hFE minimums and power dissipation limits against load requirements. Ensure the SMD mounting style aligns with assembly capabilities. Verify thermal management needs given the 200mW dissipation limit in the small outline package.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which integrate bias resistors to reduce board space and component count. The RN2911 specifically provides a dual PNP solution in a compact US-6 package. It is distinct from single-transistor variants like the RN2909 or different polarity options like the RN19xx series. The LXHF(CT) suffix indicates specific packaging and handling characteristics defined by Toshiba.

Replacement Considerations

Direct substitutes must match the dual PNP configuration, -50V VCEO, and US-6 package. Check equivalent parts from other manufacturers for compatible resistor ratios (R1/R2) and hFE specifications. Verify that any replacement also holds AEC-Q101 certification if used in automotive contexts.
