Single Bipolar Transistors Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the TO-220AB package dimensions match your PCB footprint requirements. Ensure compatibility with existing thermal management solutions given the 80 W dissipation rating at 25°C case temperature. Check for available alternative part numbers from the same manufacturer family if supply continuity is critical.

Single Bipolar Transistors Selection Notes

Select this component when a PNP Darlington transistor with 12 A continuous collector current and 80 V breakdown voltage is required. Consider the TO-220AB through-hole package for manual assembly or high-power board layouts. Evaluate thermal resistance characteristics against your heat sink capabilities. Verify that the operating junction temperature range meets your environmental specifications.

Single Bipolar Transistors Part Context

This part belongs to the BDW94 series of PNP Darlington transistors from Bourns Inc. The series includes variants with different voltage ratings, such as the BDW94A (60 V) and BDW94C.
