Single Bipolar Transistors Procurement Notes

Verify the specific suffix against the datasheet ordering information to confirm package type and lead-free status. Ensure the procurement specification matches the required hFE binning, as gain ranges vary between standard and 'A' variants. Confirm thermal management requirements align with the specified junction-to-ambient resistance values for the intended TO-92 mounting configuration.

Single Bipolar Transistors Selection Notes

Select the BC490 when a PNP transistor with -80V breakdown and -1A continuous current is required. Consider the BC490A variant if higher minimum DC current gain specifications are necessary for the application. Evaluate the thermal resistance parameters to ensure adequate heat dissipation in the chosen TO-92 package configuration under maximum load conditions.

Single Bipolar Transistors Part Context

The BC490 belongs to the High Current Transistors family manufactured by ON Semiconductor. It is housed in a TO-92 (CASE 29) plastic package. The component is part of a series that includes the BC490A variant, which offers different gain characteristics.
