Présentation

Description

The BC846ALT1G is a general-purpose NPN bipolar junction transistor (BJT) from ON Semiconductor, part of the BC846 series. Key features:
- Low power, suitable for amplification and switching.
- High current gain (hFE) with typical values of 200–450.
- Low voltage operation (VCEO = 65V, IC = 100mA).
- SOT-23 package, compact for space-constrained designs.
Common applications include signal amplification, driver stages, and switching circuits in consumer electronics, IoT devices, and embedded systems. It is a Pb-free, RoHS-compliant alternative to the standard BC846.
