Pre-biased PNP for automotive and industrial loads
The Infineon BCR162E6327 is a PNP pre-biased transistor in a SOT-23-3 package, qualified to AEC-Q101 for automotive applications. The 50 V collector-emitter breakdown and 100 mA continuous collector current cover typical low-side switching jobs: relay coils, indicator LEDs, solenoid pre-drivers in engine-control or body-electronics modules.
The 200 mW power dissipation limit in the SOT-23-3 footprint means you need to check the load duty cycle. At 100 mA and a 300 mV Vce(sat) the on-state dissipation is 30 mW, leaving plenty of headroom for switching losses at 200 MHz transition frequency. The 100 nA collector cutoff keeps leakage negligible at high temperature, which matters when the transistor shares a PCB with a hot voltage regulator.
