The BCR196WH6327XTSA1 is a PNP pre-biased transistor from Infineon, integrating a 47 kOhm base resistor (R1) and a 22 kOhm emitter-base resistor (R2) in a single SC-70 (SOT-323) package. This eliminates two external resistors per switching node, saving board area and reducing pick-and-place cost in high-volume designs. The 50 V collector-emitter breakdown and 70 mA continuous collector current suit low-power switching and interface circuits — level shifting, relay drivers, or logic-level translation up to 50 V. With a minimum DC current gain of 50 at 5 mA, 5 V, the device provides consistent drive capability across the operating range. The 150 MHz transition frequency is adequate for switching loads up to a few MHz; above that, the integrated resistors limit turn-off speed compared to a discrete transistor plus external base resistor.
Last Buy — plan the BOM transition
The BCR196WH6327XTSA1 carries a Last Buy lifecycle status. This means Infineon has announced end-of-life for this specific variant; final orders are accepted for a limited window, after which the part will no longer be manufactured. For a production line relying on this exact order code, the window to secure lifetime-buy quantities is open now. Buyers should qualify an alternative — either a second-source pre-biased PNP in SC-70 with matching resistor values (47 kOhm base, 22 kOhm emitter-base) or a discrete transistor plus external resistors — before the last-time-buy closes.
Package and storage — SC-70 reels need dry handling
The part ships in Tape & Reel (TR) format, surface-mount in an SC-70 (SOT-323) case. The supplier device package is PG-SOT323. Like most small SOT packages, this is MSL 1 or 2 depending on date code; verify the moisture sensitivity level on the reel label. If the reel has been opened past the floor-life window, bake before reflow per J-STD-033. Store the reels dry — the small body and fine pitch make them sensitive to popcorning during reflow.
