Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix matches the required specifications. The standard BP designation indicates bulk packaging containing one thousand pieces per box. Confirm the presence of the specific hFE rank suffix corresponding to the desired gain range. Ensure procurement channels are authorized distributors to guarantee genuine parts and full traceability as mandated by manufacturer policy.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring an NPN power transistor with a 150 V collector-emitter breakdown voltage. The B classification offers an hFE range of 60 to 120, suitable for specific amplification requirements. Consider the 1.8 W power dissipation limit and TO-220 thermal characteristics during layout planning. Verify compatibility with vertical deflection output topologies before finalizing the design.
