BC546BG Description

Short technical summary and product information.

BC546BG is an NPN silicon bipolar junction transistor from On Semiconductor, intended for small-signal amplification and low-power switching. Maximum ratings include a collector-emitter voltage of 65V, collector-base voltage of 80V, emitter-base voltage of 6V, and a continuous collector current of 100mA. Power dissipation is rated at 625mW at 25°C ambient and 1.5W at 25°C case temperature.

 

At a test condition of 2mA collector current and 5V collector-emitter voltage, the DC current gain is 200 minimum, 290 typical, and 450 maximum. The transistor has a transition frequency of 300MHz and features a maximum collector-emitter saturation voltage of 0.6V at 100mA. These characteristics support linear amplifier and high-frequency small-signal applications.

 

The device is available in a through-hole TO-92 (TO-226) package with straight lead, bent lead, and tape-and-reel options. It operates over a junction temperature range of -55°C to +150°C. The Pb-free package is available as noted in the datasheet.
