Pre-biased PNP for automotive and industrial switching
The Infineon BCR169E6327 is a PNP pre-biased transistor in the SOT-23-3 package (PG-SOT23-3-3), rated for 50 V collector-emitter breakdown and 100 mA continuous collector current. It integrates a 4.7 kOhm base resistor, reducing external component count in switching and interface circuits. The 200 MHz transition frequency supports moderate-speed switching applications. Automotive AEC-Q101 qualification means this part is tested and characterized for use in under-hood, chassis, and body electronics where reliability under temperature cycling and vibration is required. Typical applications include relay drivers, lamp drivers, and logic-level interface circuits in automotive ECUs, as well as industrial control modules that specify AEC-grade components.
The 50 V Vce breakdown and 100 mA Ic maximum suit this transistor for driving low-power loads such as small relays, LEDs, or logic-level signal inversion in an automotive environment. DC current gain (hFE) of 120 minimum at 5 mA, 5 V provides consistent drive capability across production lots. The 100 nA collector cutoff current (ICBO) ensures negligible leakage in off-state, important for low-power standby circuits.
Package and footprint
Supplied in the PG-SOT23-3-3 package (compatible with TO-236-3 / SC-59 / SOT-23-3 footprints), this is a surface-mount device intended for automated assembly. The 200 mW power dissipation limit should be considered in thermal design for high ambient temperature environments.
