It handles a collector-emitter breakdown of 45 V and a continuous collector current of 100 mA, with a transition frequency of 250 MHz. The DC current gain (hFE) is guaranteed at a minimum of 110 when biased at 2 mA collector current and 5 V Vce, making it suitable for small-signal amplification, load switching up to 100 mA, and level translation in mixed-voltage logic circuits. Maximum power dissipation is 330 mW, which sets the thermal budget for the application. ## Package and mounting — Bulk delivery For a pick-and-place line, you will need to transfer the parts to a feeder-compatible carrier or hand-place them. The package is a standard TO-236-3 (SC-59, SOT-23-3) with the Infineon PG-SOT23 supplier code. Surface-mount reflow profile follows the standard MSL 1 / MSL 3 floor-life guidelines for SOT-23 — no special bake required if the original moisture-barrier bag is unopened. ## Sourcing and lifecycle No official second-source or pin-compatible cross is listed in the Infineon documentation for this exact suffix, but the BC846 family is broadly interchangeable with other 45 V NPN SOT-23 parts from multiple manufacturers — verify the hFE bin and package code against your design.","metaTitle":"Infineon BC846AE6433 NPN Transistor, 45 V, 100 mA, 250 MHz","metaDescription":"Infineon BC846AE6433 NPN transistor: 45 V Vce, 100 mA Ic, 250 MHz fT, hFE min 110.
