Single Bipolar Transistors Procurement Notes

Verify the specific manufacturing lot and date code upon receipt to ensure compliance with project timelines. Confirm that the TO-18-3 ceramic package matches the PCB footprint requirements. Check for any specific handling instructions regarding moisture sensitivity or electrostatic discharge protection during storage and assembly processes.

Single Bipolar Transistors Selection Notes

Select this component when a hermetic ceramic package is required for reliability in harsh environments. Consider the 45 V breakdown voltage and 100 mA current limits to ensure adequate headroom for the intended load. Evaluate the thermal management needs given the 600 mW power dissipation capability in the specified package style.

Single Bipolar Transistors Part Context

This part belongs to the standard 2N2432 series of NPN transistors manufactured by Microchip Technology. It represents a legacy discrete semiconductor product often used in replacement scenarios for older designs. The TO-18 can package distinguishes it from modern surface-mount alternatives, targeting applications where traditional leaded components are mandated.

Single Bipolar Transistors Replacement Considerations

Consult official Microchip documentation for direct cross-reference equivalents. Verify pinout compatibility and electrical parameter overlaps before substituting with other NPN BJT models in the same voltage and current class.
