BC818-40LT1G Description

Short technical summary and product information.

The BC818-40LT1G is an NPN silicon epitaxial planar transistor designed for general purpose amplifier and switching applications. It is manufactured by On Semiconductor (onsemi) and offers a maximum collector-emitter voltage (VCEO) of 25V, collector-base voltage (VCBO) of 30V, and emitter-base voltage (VEBO) of 5V. The continuous collector current is rated at 500 mA, with a total device dissipation of 225 mW on an FR-5 board and 300 mW on an alumina substrate at 25°C ambient temperature.

 

The transistor features a DC current gain (hFE) range of 250 to 600 at 100 mA collector current and 1V VCE, with a minimum gain of 40 at 500 mA. The saturation voltage (VCE(sat)) is typically 700 mV at 500 mA collector current and 50 mA base current. The transition frequency (fT) is a minimum of 100 MHz at 10 mA and 5V VCE, making it suitable for low-frequency to moderate-speed switching circuits. Output capacitance is typically 10 pF.

 

The device is housed in a SOT-23-3 surface-mount package (also known as TO-236-3 or SC-59) and is supplied in tape and reel packaging with 3000 pieces per reel. The BC818-40LT1G is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. The operating junction temperature range is -55°C to 150°C, with a maximum junction-to-ambient thermal resistance of 556°C/W on FR-5 board and 417°C/W on alumina substrate.
