Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin, as this part number has been associated with both onsemi and Sanyo historically. Confirm that the received component matches the TO-126LP physical dimensions and pinout configuration required for your PCB layout. Ensure the datasheet provided aligns with the specific batch production date to guarantee compliance with current material specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with moderate voltage ratings and high current capacity is required. The TO-126LP package offers superior heat dissipation compared to smaller surface-mount alternatives. Consider the 130 MHz transition frequency for applications requiring faster switching speeds than standard low-frequency transistors provide.

Single Bipolar Transistors Part Context

This component belongs to the family of discrete power bipolar transistors used in general-purpose electronics. It serves as a fundamental switching element in circuits where PNP polarity is necessary. The design supports legacy and modern industrial designs requiring durable, through-hole mounted semiconductor solutions.

Single Bipolar Transistors Replacement Considerations

Check for direct equivalents from other manufacturers offering identical 50V/8A PNP specifications in TO-126LP packages. Verify pin compatibility and thermal resistance values before substitution.
