Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'T' corresponds to the bag packing specification of 200 pieces per bag as documented in the official datasheet. Confirm that the TO-126ML package dimensions and pinout match the target PCB footprint requirements before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when high voltage handling up to 160 V and substantial current drive near 1.5 A are required in a through-hole configuration. Consider the plastic-covered heat sink design if thermal management without additional insulating washers is preferred. Ensure the application environment stays within the specified -55°C to +150°C operating temperature limits.

Single Bipolar Transistors Part Context

This NPN transistor belongs to the 2SC3902 series, functionally paired with the PNP 2SA1507. Both devices share identical electrical ratings and utilize the same TO-126ML package. They are designed as complementary pairs for push-pull amplifier stages and switching applications requiring matched performance characteristics between NPN and PNP types.

Single Bipolar Transistors Replacement Considerations

The 2SA1507 serves as the direct PNP complement within the same family. Verify compatibility with other general-purpose NPN transistors offering similar 160 V ratings and 1.5 A current capacity in TO-126ML packages, ensuring saturation voltages and gain bandwidth meet circuit requirements.
