RN2907,LXHF(CT

Overview

The RN2907,LXHF(CT is a PNP digital transistor array manufactured by Toshiba Semiconductor and Storage, designed for automotive applications under the AEC-Q101 qualification standard. It integrates two PNP transistors with built-in bias resistors in a compact US-6 (SOT-363) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. The device features a typical input resistance of 47 kOhms and a power dissipation rating of 200 mW. It operates at a maximum junction temperature of +150°C and supports switching frequencies up to 250 MHz, making it suitable for high-speed interface and driver circuits.

Feature Summary

• Dual PNP configuration with integrated bias resistors simplifies circuit design by reducing component count.
• Automotive-grade reliability certified under AEC-Q101 standards for robust performance in vehicle electronics.
• Compact US-6 surface-mount package enables efficient space utilization on printed circuit boards.

Applications

• Switching circuits in automotive electronic control units
• Inverter drive circuits for motor control systems
• Interface connections between logic gates and loads
• Driver circuits for relays or small actuators

Procurement Notes

Verify the specific suffix LXHF(CT) against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure that the ordering quantity aligns with the factory reel size of 3000 units if bulk procurement is required. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as automotive-grade components may have longer supply cycles than commercial equivalents.

Selection Notes

Select this component when a dual PNP digital transistor solution is required for automotive environments. The 47 kOhm base resistor value should be evaluated against the driving source impedance to ensure adequate base current for saturation. Consider the 200 mW power dissipation limit in the SOT-363 package when designing thermal management strategies for high-density layouts.

Part Context

This part belongs to Toshiba's RN series of pre-biased transistors, which are optimized for automotive use. The RN2907 variant specifically provides a dual PNP configuration, contrasting with NPN-only or complementary NPN/PNP pairs found in other models like the RN4901. The LXHF suffix typically denotes specific packaging and environmental compliance attributes defined by Toshiba.

Replacement Considerations

Direct substitutes within the same family include RN2906,LXHF(CT for different resistor ratios. External replacements must match the -50V VCEO, -100mA IC, and US-6 package footprint. Verify that alternative parts also meet AEC-Q101 requirements if used in automotive applications.
