The Infineon BCR119WE6327HTSA1 is an NPN pre-biased transistor in a SC-70 / SOT-323 package, integrating a 4.7 kOhm base resistor (R1) so the part switches on with a logic-level signal without an external resistor. Rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, it handles 250 mW max dissipation. With a 150 MHz transition frequency and DC current gain (hFE) of 120 minimum at 5 mA, 5 V, it suits low-power load switching, relay drivers, and logic interface circuits in industrial controls, consumer electronics, and general-purpose switching up to 50 V rails.
The BCR119WE6327HTSA1 carries an Obsolete lifecycle status. Infineon no longer manufactures this exact variant, so new-production orders go through independent distribution and surplus channels. For a pin-compatible replacement within the BCR119 family, the BCR119W (base part number) in the same SOT-323 package is the closest functional match — verify the suffix and date code for your specific bias resistor configuration.
PG-SOT323 — rework and footprint notes
The supplier device package is PG-SOT323, a standard three-lead SOT-323 body. Surface-mount with a small footprint — about 2.0 mm × 1.25 mm — so it fits tight layouts but needs a steady hand under the hot-air station. Low thermal mass means it reflows quickly; keep the nozzle temperature around 300 °C and avoid dwelling more than a few seconds to prevent pad lifting.
