Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank (R or S) required for your circuit design, as the datasheet specifies distinct gain ranges. Confirm the component lifecycle status on the manufacturer's website, as this model may be subject to maintenance or discontinuation phases. Ensure compliance with RoHS directives if applicable to your manufacturing standards.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor with high gain and low saturation voltage is needed for low-frequency applications. Consider the 20 mA continuous current limit and 200 mW power dissipation constraints. The Mini3-G1 package is suitable for automated insertion and space-constrained designs.

Single Bipolar Transistors Part Context

This part belongs to Panasonic's lineup of silicon NPN epitaxial planar transistors intended for general-purpose low-frequency amplification. It utilizes a Mini3-G1 surface-mount package to facilitate equipment miniaturization and automated assembly processes through tape and magazine packing methods.

Single Bipolar Transistors Replacement Considerations

Consult official documentation for verified substitutes. Cross-referencing requires matching the Mini3-G1 package, 100 V collector-emitter voltage, and comparable hFE and fT specifications.
