Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as the component may be produced by Continental Device India Limited (CDIL) under license rather than directly by STMicroelectronics. Confirm the package type matches the required TO-18 metal can specifications. Check for any obsolescence notices or lifecycle status updates from the supplier before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high voltage handling capabilities within a small-signal transistor form factor. Ensure the thermal management strategy accounts for the specified junction-to-ambient thermal resistance values. Verify that the required DC current gain falls within the documented minimum range for the intended operating conditions.

Single Bipolar Transistors Part Context

This part belongs to the family of high-voltage bipolar junction transistors manufactured using planar epitaxial processes. It serves as a specialized discrete semiconductor device intended for analog signal processing tasks where standard low-voltage transistors would fail due to breakdown limitations.
