Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead times and packaging formats. The 'TRE' designation typically indicates tape and reel packaging, whereas other suffixes may denote bulk quantities. Confirm RoHS compliance status and pinout orientation prior to integration into printed circuit board designs to ensure correct assembly and operational reliability.

Single Bipolar Transistors Selection Notes

Select this component when a PNP small-signal transistor with moderate voltage handling capabilities is required. The 60 V rating suits low-voltage DC applications. Consider the 625 mW power dissipation limit for thermal management. Ensure the TO-92 package fits the mechanical constraints of the target design compared to surface-mount alternatives.

Single Bipolar Transistors Part Context

This part belongs to the Central Semiconductor PN series of small-signal bipolar transistors. These components are silicon-based NPN or PNP devices intended for general-purpose use. The series provides reliable performance for consumer electronics and industrial control applications requiring discrete switching or amplification functions in compact through-hole form factors.

Single Bipolar Transistors Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements must match the PNP polarity, TO-92 package, and minimum 60 V / 500 mA ratings to maintain circuit functionality without redesign.
