Pre-biased PNP with integrated 47 kΩ base resistor
The Toshiba RN2413,LXHF is a PNP pre-biased transistor that integrates a 47 kOhms base resistor (R1) directly into the SOT-23-3 package. This eliminates the external base resistor from the BOM, saving board space and reducing placement cost in high-volume automotive assemblies. The 200 MHz transition frequency gives it enough speed for PWM switching and relay/ solenoid drivers in 12 V and 24 V vehicle electrical systems.
Automotive-grade qualification and operating margins
Maximum power dissipation is 200 mW, so derating is needed if the ambient exceeds 85 °C in a dense PCB layout.
SOT-23-3 footprint and sourcing
Housed in a standard SOT-23-3 (TO-236-3 / SC-59) surface-mount package, the RN2413,LXHF fits existing footprints for pre-biased transistors without layout changes.
