Procurement Notes

Verify the specific suffix designation to confirm the exact current gain bin, as the BCP56H series offers multiple gain options. Ensure the ordering part number matches the required gain selection for your circuit design. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the datasheet revision date to ensure compatibility with latest thermal guidelines.

Selection Notes

Select this component when an NPN transistor with 80V blocking capability and 1A current handling is required in a surface-mount format. The SOT-223 package provides adequate thermal performance for 2.2W dissipation. Consider the available current gain bins to match amplifier linearity or switching speed requirements. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This device belongs to the Nexperia BCP56H family of medium power NPN transistors. The family is designed for general-purpose applications requiring robust performance in compact packages. The BCP56HX variant specifically denotes the SOT-223 packaging configuration. These components are widely used in both consumer and automotive electronics due to their balance of electrical performance and physical size.

Replacement Considerations

Direct substitutes include other NPN transistors with similar 80V/1A ratings in SOT-223 packages, such as the BCY56 or equivalent generic alternatives. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement device meets the same AEC-Q101 automotive qualification if used in automotive contexts.
