Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'AC' against official datasheets to confirm binning or grading variations. Ensure the TO-92-B1 package dimensions match the design requirements. Confirm RoHS compliance status for the specific manufacturing batch. Cross-reference the manufacturer's latest ordering information to ensure availability and correct part identification.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 0.5 A continuous current capability is required in a compact TO-92 package. It serves as the complementary pair to the 2SC1317Q NPN transistor. Consider its 25 V breakdown voltage and 0.625 W power dissipation limits for thermal management in low-power amplifier designs.

Single Bipolar Transistors Part Context

This component belongs to the family of small signal bipolar transistors manufactured by Panasonic and distributed by onsemi. It is specifically engineered for use in audio and general-purpose amplifier stages where low saturation voltage and high current gain are beneficial. The TO-92 package provides a cost-effective solution for through-hole mounting.

Single Bipolar Transistors Replacement Considerations

The 2SC1317Q is the documented complementary NPN counterpart. Verify pinout compatibility before substitution. Check if alternative PNP transistors meet the 0.5 A current and 25 V voltage ratings.
