It integrates a 4.7 kOhm base resistor (R1) and a 47 kOhm emitter-base resistor (R2), eliminating the need for external bias components in switching and inverter circuits. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the device dissipates up to 250 mW. Transition frequency is 160 MHz, suitable for low-to-mid frequency switching up to a few megahertz.","metaTitle":"Infineon BCR166WH6327XTSA1 PNP Pre-Biased Transistor","metaDescription":"Infineon BCR166WH6327XTSA1 PNP pre-biased transistor, 50 V, 100 mA, 160 MHz, 250 mW.
