Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'E' against the official ON Semiconductor datasheet EN2086C to confirm packaging or tape-and-reel specifications. Ensure the component matches the required PNP polarity and -50V/-8A ratings for your circuit design. Cross-reference the manufacturer part number to avoid confusion with similar models like the 2SB1203. Confirm RoHS compliance status if required by your manufacturing standards.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with -50V breakdown and -8A continuous current is required in a surface-mount TO-252 package. It is suitable for applications demanding low saturation voltage and fast switching speeds. Consider thermal management requirements as the device dissipates power in a compact footprint. Verify that the high fT meets the frequency demands of your specific inverter or converter topology.

Single Bipolar Transistors Part Context
