Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix (e.g., _D87Z) against official documentation to confirm packing method and reel size. Ensure compatibility with ON Semiconductor system requirements following Fairchild integration updates. Confirm RoHS compliance status and check for any recent product change notices or marking changes before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with high voltage capability (-150 V) and moderate current handling (-600 mA) is required. Consider the thermal resistance and power dissipation limits relative to the ambient temperature. Verify that the SOT-23 footprint matches the PCB layout constraints and that the transition frequency meets the signal bandwidth requirements.

Single Bipolar Transistors Part Context

This part belongs to the MMBT series of small-signal transistors manufactured by ON Semiconductor. It represents a legacy Fairchild Semiconductor design now integrated into the ON Semiconductor portfolio. The device is commonly used in consumer electronics and industrial control systems where reliable high-voltage switching is needed in a minimal footprint.

Single Bipolar Transistors Replacement Considerations

Check for updated part numbers due to Fairchild integration naming conventions. Verify pinout compatibility if substituting with other PNP SOT-23 transistors. Ensure replacement parts meet the same voltage, current, and thermal specifications.
