Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official Toshiba Semiconductor documentation to confirm lead time and environmental compliance status. Confirm that the 'O' marking corresponds to the required hFE classification range for your design. Ensure the LF designation matches the intended RoHS compliance requirements for your manufacturing process.

Single Bipolar Transistors Selection Notes

Select this component when a small surface-mount PNP transistor is required for audio or driver applications. Consider its complementary relationship with the 2SC4118 for push-pull configurations. Evaluate the thermal derating curves if operating near the maximum junction temperature limits on standard PCB layouts.

Single Bipolar Transistors Part Context

This part belongs to Toshiba's lineup of general-purpose bipolar junction transistors manufactured using the PCT process.
