BC846ALT1G

The BC846ALT1G is an NPN silicon general purpose transistor from ON Semiconductor, designed for low-power switching and amplification applications. It is part of the BC846ALT1G series and is offered in a compact SOT-23-3 surface mount package.

Key electrical specifications include a minimum collector-emitter voltage (VCEO) of 65V, a minimum collector-base voltage (VCBO) of 80V, and a minimum emitter-base voltage (VEBO) of 6.0V. The continuous collector current is rated at 100mA. DC current gain (hFE) is a minimum of 110 at IC=2mA and VCE=5V, with a maximum saturation voltage (VCE(sat)) of 600mV at IC=100mA and IB=5mA. The typical transition frequency is 100MHz.

Power dissipation is rated at 300mW on an alumina substrate at 25°C ambient, derating at 2.4mW/°C above 25°C. On an FR-5 board, dissipation is 225mW with a derating of 1.8mW/°C. Thermal resistance junction-to-ambient is 417°C/W on alumina and 556°C/W on FR-5. The device operates over a junction temperature range of -55°C to 150°C. It features high ESD ratings: >4000V Human Body Model and >400V Machine Model.

The BC846ALT1G is Pb-free, Halogen Free/BFR Free, and RoHS compliant. Moisture sensitivity level is 1. It is suitable for general purpose switching and amplification in consumer electronics, signal processing, and other low-power circuits.
