Single Bipolar Transistors Procurement Notes

Verify the exact part number spelling, including punctuation, as distributors may list it with or without the comma. Confirm the manufacturer is NXP Semiconductors. Ensure the package type matches the required TO-92 SMD variant. Check for RoHS compliance documentation if required by your manufacturing standards. Cross-reference the suffix '112' with official NXP ordering codes to ensure correct reel packaging specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a 65V breakdown voltage and 100mA current limit is required. The 'B' grade indicates a specific current gain range; verify that this gain band meets your circuit's amplification requirements. Consider the TO-92 SMD package dimensions for PCB layout compatibility. Evaluate thermal dissipation needs against the device's power handling capabilities in your specific application environment.

Single Bipolar Transistors Part Context

This component is part of the BC556 family of PNP transistors from NXP. The family includes variants with different current gain grades (such as A and C) and packaging options. The BC556 series is widely used in consumer electronics and industrial control systems due to its reliability and cost-effectiveness for small-signal applications.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include other PNP transistors with similar Vceo and Ic ratings, such as the BC557 or 2N3906, provided the pinout and gain characteristics are verified. Always check datasheet parameters for direct replacement suitability.
