It holds the bias point steady across temperature and supply shifts, which is exactly what a PA stage needs to stay linear. The part is qualified to AEC-Q101, so it's rated for automotive under-hood environments where vibration and thermal cycling are the norm. Supply range runs from 1.6V up to 18V, covering the 12V automotive rail through cold-crank dips and load-dump spikes. ## Package and footprint — SC-82A SOT-343 Housed in a 4-pin SC-82A SOT-343 surface-mount package, the BCR400WH6327XTSA1 takes up minimal board area. The supplier device package is PG-SOT343-4-1. For rework, it's a small part — hot-air profile around 260°C peak, standard lead-free reflow. No exposed pad, so the thermal path is through the pins; keep the copper pour under the part for a bit of heatsinking if the ambient runs hot. ## Lifecycle and sourcing — still in active production That means no last-time-buy clock ticking, no end-of-life scramble.","metaTitle":"Infineon BCR400WH6327XTSA1 Active Bias Controller, AEC-Q101","metaDescription":"Infineon BCR400WH6327XTSA1 active bias controller for RF power transistors.
