AEC-Q101 automotive pre-biased PNP — package and bias network
The Toshiba RN2104MFV,L3XHF(CT is an AEC-Q101-qualified PNP pre-biased transistor in a SOT-723 VESM package, rated for 50 V collector-emitter breakdown and 100 mA continuous collector current. The integrated bias network — 47 kOhm base resistor (R1) and 47 kOhm emitter-base resistor (R2) — eliminates two external passives from the BOM, saving board space and reducing pick-and-place cost in high-volume automotive modules.
Saturation voltage and switching performance
Vce(sat) is specified at 300 mV maximum with a 500 µA base drive and 5 mA collector current — the low on-state voltage keeps conduction losses under 1.5 mW at that operating point, well within the 150 mW total power dissipation envelope. Transition frequency is 250 MHz, so the device handles PWM switching in the low-MHz range without significant gain rolloff.
Board-fit and temperature-grade context
The SOT-723 VESM footprint measures roughly 1.2 mm × 1.2 mm with a seated height under 0.5 mm — this is one of the smallest packages for a pre-biased transistor, suited for ECU sub-assemblies where every mm² of PCB real estate is budgeted. The Automotive grade (AEC-Q101) means the part has passed the full suite of reliability stress tests: temperature cycling, high-temperature reverse bias, and autoclave. PPAP documentation is available on request for OEM audit packages.
