Its 250 MHz transition frequency keeps it useful for audio preamp stages, signal conditioning, and moderate-speed switching up to a few tens of megahertz. The 330 mW power limit in the SOT-23 footprint means you need to watch the collector current and Vce product — at 100 mA continuous, the Vce must stay under about 3.3 V to stay within the dissipation budget at 25 °C ambient. ## Saturation and gain — where the numbers matter Vce(sat) is specified at 600 mV maximum with a 5 mA base drive and 100 mA collector current, so a forced beta of 20 gives a clean low-side switch with less than 0.6 V drop. Minimum DC current gain (hFE) is 110 at 2 mA, 5 V, which is typical for the BC846A gain group — this is the 'A' suffix version, meaning it is binned for a tighter hFE range than the base BC846, useful when you need consistent gain across a production run. Collector cutoff current is just 15 nA maximum, so leakage in the off state is negligible for most battery-powered designs. ## Package and temperature — fitting the board The SOT-23 package (TO-236-3, SC-59, SOT-23-3) is a standard footprint shared by thousands of small-signal transistors, so the BC846AE6327 drops in as a direct replacement for any BC846-series part in the same package. Operating junction temperature is rated to 150 °C, which gives margin in moderately warm environments — fine for consumer, industrial, and automotive cabin applications as long as the ambient plus self-heating stays under that limit. Surface-mount assembly with standard reflow profiles; no special baking required unless the moisture-sensitive level (MSL) rating of the reel demands it — the SOT-23 typically runs MSL 1 or 2.","metaTitle":"Infineon BC846AE6327 NPN Transistor, 45 V, 100 mA, SOT-23","metaDescription":"Infineon BC846AE6327 NPN general-purpose transistor. 45 V Vce, 100 mA Ic, 330 mW max power, 250 MHz fT.
