Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific hFE binning corresponds to Group 16 requirements for your circuit design. Ensure storage conditions remain within specified limits to maintain lead integrity prior to soldering.

Selection Notes

Select this component when a high-gain NPN transistor is required for low-power audio or signal applications. The SOT-23 package offers compact surface-mount integration. Verify that the 500 mA current rating and 45 V voltage limits align with the operational parameters of the target system.

Part Context

This part belongs to the BC817K series of NPN silicon transistors designed for general-purpose use. The 'K' suffix indicates the SOT-23 package variant, while '16' specifies the DC current gain grouping. The E6327HTSA1 suffix denotes specific ordering and packaging details defined by Infineon.

Replacement Considerations

Direct substitutes include other BC817 variants with matching gain groups, such as BC817K25 or BC817K40, provided the hFE ranges are compatible. Cross-referencing pinouts and thermal resistance values is essential when considering alternative manufacturers.
