Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer designation and package marking against official Panasonic Electronic Components documentation to confirm authenticity. Ensure that the procurement channel provides traceable component history. Cross-reference the part number with authorized distributor lists to avoid counterfeit sources. Confirm RoHS compliance status directly from the latest datasheet revision, as legacy components may have varying environmental certification records depending on production batch dates.

Single Bipolar Transistors Selection Notes

Select this component when circuit requirements demand a PNP transistor with high voltage handling capabilities in a through-hole format. The 150 V breakdown voltage makes it suitable for higher potential applications compared to standard low-voltage alternatives. Consider the 50 mA current limit when designing load paths. The TO-126B-A1 package requires appropriate thermal management strategies if operating near the 1.2 W dissipation limit under continuous load conditions.

Single Bipolar Transistors Part Context

This component belongs to the broader category of single bipolar transistors manufactured by Panasonic Industry. It serves as a discrete semiconductor device within larger electronic assemblies.
