That eliminates two passives from the BOM and shrinks the board footprint for a simple digital-switch or inverter function. ## 50 V, 100 mA — where it fits Collector-emitter breakdown is rated at 50 V, with a continuous collector current of 100 mA and a power dissipation ceiling of 250 mW. ## 160 MHz transition frequency — switching speed headroom Transition frequency is 160 MHz. Saturation voltage is 300 mV max at 500 µA base and 10 mA collector. ## Package and mounting The SOT-723 package (also marked as PG-TSFP-3) is a three-lead body. ## Obsolete — sourcing path Infineon lists the BCR 166F as obsolete.","metaTitle":"Infineon BCR 166F E6327 PNP Pre-Biased Transistor, SOT-723","metaDescription":"Infineon BCR 166F E6327 PNP pre-biased transistor, 50 V, 100 mA, 250 mW, SOT-723.
