Single Bipolar Transistors Procurement Notes

Verify the specific lifecycle status before procurement, as this component may be classified under maintenance or discontinued categories. Consult official Panasonic semiconductor channels for the most up-to-date availability information and confirm that the latest specifications satisfy your design requirements prior to finalizing orders.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high-speed switching characteristics within a low-voltage range. Ensure the thermal management strategy accommodates the 2.0 W power dissipation rating at 25 °C ambient temperature without a heat sink, or utilize the flange mount capability for higher thermal loads. Verify that the 50 V collector-emitter voltage rating aligns with the circuit's operational limits.

Single Bipolar Transistors Part Context

This part belongs to the Panasonic Power Transistors series, specifically utilizing silicon NPN epitaxial planar technology. It is housed in the TO-220F-A1 (EIAJ SC-67) package, which provides an isolated case connection. The device is intended for standard applications such as office equipment, measuring instruments, and household appliances, rather than specialized aerospace or life-support systems.
